The Towers of Aurum: a Chronicle of Aurenthal

Each to a gate, and all to the flame. What comes through one comes against four. A saying of the Ember Ring, since the Night of Four Gates

The Runner and the Letter

On the evening of the thousandth night, Kiri of the Four Cups was handed a letter she should not have carried, by a fox she should not have trusted, and told to take it to an orc she should on no account bother.

She was thirteen, and had been a gate runner for nine months, which made her a veteran. Gate runners grew too tall for the roof ladders, or too sensible, or took a wrong turn in the middle of a wave and met something coming the other way. Kiri had no intention of growing sensible.

"Moonrise Gate to Ashfall Gate," said the fox. "By hand. Into his hand, mind, not a sergeant's. Not a cook's. Not some nephew with a hammer and opinions."

His name was Sen Amagiri and he was a courier of the Lantern Post, the messengers of the Kitsune Court of Lanterns, who carry the Accord's letters around the four lands, and he had the long silver ears and the fine, faintly amused face of the Moonwood. He also had a crumb of Ronin custard bun on his collar, which spoiled the effect.

Kiri looked at the seal. It was silver wax, pressed with a fox whose nine tails curled round it like smoke.

"That's her seal," she said. "That's her seal."

"It is."

"To him?"

"Keep your voice down, there are ears in the walls of this quarter, and most of them are mine." Sen glanced along the gallery, where the Kitsune wardens were lighting the frost lanterns one by one along the road the Hollow take, blue fire blooming in glass. "I would take it myself, but the Iron Father once offered to use me as a boot brush, and he did not seem to be joking."

"You've read it," said Kiri.

"I have not."

"You read everything. Brother Mugi says you'd read the bottom of a teacup if someone had written on it."

"Brother Mugi is a wise and slanderous panda." Sen pressed the letter into her hands and closed her fingers over it. For a moment his face was not amused at all. "It is the one letter in eleven years of the Post that I have not opened. Let that tell you how heavy it is. Run, Kiri. The bells are close tonight."

So she ran.

The Ember Ring at dusk is the most beautiful city in Aurenthal, and everyone who lives there will tell you so, usually before you have asked. It is built in rings, road inside road inside road, seven of them, white stone stepping down towards the centre like the inside of a great bowl. The roofs are gold tile. In the evening light they burn as though the whole city were a hearth and every roof a coal. And at the heart of it all, on the white dais called the Hearthstone, burns Hoshibi.

You can see the flame from anywhere in the Ring. It is not large, as fires go. But its light is like no other light: warm without being hot, steady without being still, gold at the edges and something whiter than white at the heart. Moss grows in every crack of every step in the Ring. Window boxes bloom in midwinter. Old people say they feel younger near the Hearthstone, and young people say the old people are only saying that, and both are right in their way.

Kiri ran along the gallery of the Dusk Quarter, which is what the Kitsune call theirs, past the frost lanterns and the Volt Coils humming on the copper roofs and the paper talismans fluttering on their strings, down the runner stairs that only runners and cats used, and out onto the roofs. Up here the city spread below her like a round cake cut in four: the Dusk Quarter silver and blue in the north, the Ronin quarter white and ruled-straight in the east, the Shrine quarter a green blur of bamboo and lotus in the south, and in the west, where she was going, the Oni quarter glowing red, its forge chimneys breathing sparks into the dusk.

Four quarters. Four peoples. Four great gates, one in each corner of the city, where the old roads came in.

And in each of the four gates, for a thousand nights now, a wound.

The Moonrise Gate had been a lovely thing once, an arch of white stone carved with foxes leaping. The arch still stood. But inside it, where there should have been road and evening and the silver line of the Moonwood on the horizon, there was a greyness, a soft, shifting dark like a window onto a rainy night in some city nobody knew. Lights moved in it sometimes. Not lantern lights: smaller, colder, square-edged, in rows. And the smell that came out of it, when the wind was wrong, was wet stone and hot metal and old paper, the smell of a place that had been rained on for a hundred years.

The bells began as she reached the Hearth Round.

Every gate had its bell, and every bell its voice. Kiri knew them all. The deep iron gong of the Ashfall Gate. The old bronze temple bell of the Moonrise and its three younger brothers. The single clean strike of the Riverwhite Gate, where the Ronin stood, once and once again, like a judge's gavel. The wooden clatter of the Greenroot Gate in the south, which the pandas swore was a bell and everyone else swore was a lot of bamboo falling down a staircase. All four were ringing now.

Then, under the bells, the drum.

It came from the north west, from the Ashfall Gate, and it went through the stones of the city and up through the soles of Kiri's feet. Doom. Doom. Doom-da-doom. That was the Raiden Drum, and Benika's code. One beat for each gate, then the rolling beat that meant walkers on the road, all gates, steady. Every defender in the city knew it. Ronin sergeants who would rather have eaten their own sandals than learn anything from an orc had learned that drum code by heart in the first week, because on the Night of Four Gates it had been the only thing everyone could hear.

Kiri cut through the Hearth Round, the innermost road, the one that ran in a circle around the Hearthstone. Here the light of Hoshibi fell full on her and she felt it as she always did, like walking out of shade into sun. She did not stop. Runners did not stop.

She stopped.

Only for a breath, because there was a cart across the lane, a great iron-wheeled thing piled with barrels of rice and crates of mortar shells and one small locked strongbox, and behind it, swearing in the precise, grammatical way of a man who had been properly educated, was Quartermaster Hachirō Mibu.

"Kiri. Good. Go round. No, go over, you have legs like a heron. Tell the Ashfall cooks that if they want their rice they may come and collect it like civilised persons, and if they send that boy Tetsuo to borrow it again I will have his tusks for chopsticks."

"Yes, Quartermaster."

"And tell them the shells are Ronin weight, not Oni weight. Ronin weight is correct. And the aurum in that box is the Ashfall share for the week, to the grain, exactly the same as every other gate's. If the Iron Father wants more for his towers he may write to me, like the Marshal does, and the Ninth Tail does, and Sister Mei does, every week."

"Yes, Quartermaster."

"And Kiri." He caught her eye over the barrels. Hachirō was sixty, grey, stiff in one leg from the Night of Four Gates, and he kept the Common Stores of all four gates, and the aurum that every tower in the city needed and there was never enough of, with a ledger in one hand and an abacus on his belt, and in nine months Kiri had never once seen him smile. He did not smile now. "Whatever you are carrying that has made your face go that colour, do not drop it."

She went over the cart.

As she came down on the far side, something landed on her shoulder with a small, papery whumph.

"Hello!" said Tomo.

Tomo was a paper lantern about the size of a cat, round and warm and lit from within by a light that no one had ever been able to find the candle for. Tomo had two dark eyes painted on, or perhaps not painted, and a mouth that was sometimes there and sometimes not, and a habit of turning up wherever someone in the Ring was new, or lost, or frightened, and saying hello. Nobody knew where Tomo had come from. Nobody, after a thousand nights, really minded.

"You're supposed to be guiding the new defenders," said Kiri, running.

"I am," said Tomo. "You're new at this."

Kiri did not ask how a lantern knew what she was carrying.

Little Akagane, the Oni quarter, took her in with its heat and its noise. Forges stood open to the street, and somewhere a choir of very large people was singing a song about a goat, in harmony, between mortar volleys. Ahead, the Ashfall Gate rose against a sky going violet, its arch carved with hammers and flames, and inside the arch, the grey.

Things were walking out of the grey.

They looked, at first, like people. They wore long grey coats and carried flat black cases in their hands, and they walked with their heads down at the same pace, in the same direction, like a crowd leaving a building at the end of a long day. Their faces were smooth and blank as eggshell. The defenders called them Salaryman Husks, a word nobody in Aurenthal could have explained. Behind them came lean shapes that ran bent double with satchels on their backs, the Couriers, and behind those, heavy and slow, the Riot Shells in their plate.

The Oni were waiting for them.

Along the walls the towers woke, aurum glowing gold in their hearts like coals breathed on, and the mortar crews sang while they worked, because the gunner timed the shot to the end of the verse. And on the platform above the arch, Benika Thunderhand beat the Raiden Drum with both arms, a tall, deep-voiced orc woman with her hands wrapped in leather and her eyes closed, while lightning crawled along the iron of every tower near her at each stroke. She had never said who the drum was named for. Nobody at the Ashfall Gate needed to ask.

On the wall beside the gatehouse, leaning on a war hammer as tall as Kiri, stood the Iron Father.

Gorō Akagane was the oldest of all the Oni warlords and looked it, the way a mountain looks old. His skin was the deep red of a forge coal. One horn swept up and back; the tip of the other was a jagged stump, broken in a fight he still laughed about. A brass ring shone on his left tusk, and across his back, as always, hung two hammers that were not his own. He was watching the road with the patient, interested face of a farmer watching weather.

"Runner," he said, without looking round. "Bring it here, little one. I can smell fox wax from the stairs."

Kiri held out the letter. He took it in a hand that could have closed around her head, and broke the seal with his thumbnail, and read.

She watched his face. She had seen him laugh, roar, weep at a funeral, and once eat an entire roast pig at a sitting to settle a bet with a Ronin castellan. She had never seen him do what he did now, which was go completely still.

Below them the first Husks reached the mortar line and the shells came down and the night lit orange. Benika's drum rolled. Tomo, on Kiri's shoulder, gave a small yawn and said, "Wake me for the next wave," and dimmed.

And then, from inside the grey of every gate at once, there came three soft rising notes, like a chime in a great empty hall, and a voice spoke. It was a pleasant voice. Polite. Unhurried. The voice of someone reading a notice they had read ten thousand times.

"Good evening. This is the one thousandth night. All four gates. All four peoples." A small pause, almost kind. "Thank you for your patience. It will not be required much longer."

Gorō folded the letter and put it inside his coat, over his heart.

"Tell the fox," he said, and his voice was quiet, which Kiri had never heard either, "yes."

"Just yes?"

"Just yes." Then he looked down at her at last, and his old face creased, and he laughed, though it was not quite his usual laugh. "Go on, runner. Go round by the Four Cups and get yourself fed. It is going to be a long night, and a longer year, and I would like you to be alive for both."

It was the first time in the history of Aurenthal that a Kitsune had written to an Oni and been answered in a single word. Kiri did not know that yet. She knew only that the Iron Father's hand, on the letter, had not been entirely steady, and that over the roofs, in the heart of the city, Hoshibi burned as it had for a thousand years and more, warm and steady and alive, as though it were listening.

To understand what was in that letter, and why an old orc's hand shook to hold it, you must go back. Not a thousand nights. A great deal further than that.

The Age of First Fire

Before the Ember there was the grey, and the grey had no edges, and nothing in it had a name. The opening of the Lamplighters' Telling, recited at every Kindling

In the beginning there was a sun, and it was young.

All the peoples of Aurenthal agree on that much, and very little else. The first sun walked the sky alone above a world of cold stone, and below it, everywhere, lay the grey: not cloud, not sea, something soft and white and endless that swallowed sound the way snow does. Nothing grew in the grey. The few creatures that lived at its edges lived small, cold lives: grey-hided giants in the western caves, a hungry silver fox in a forest that had forgotten what leaves were for, a people of the eastern rivers with no shoes and no fire, and in the south, a round, slow, patient folk who walked everywhere as though they had all the time in the world, because in the grey, they did.

Then a piece of the sun came down.

Here the stories part like a river round a rock, and every people takes its own channel. The Oni say the sky split like a struck anvil. The Ronin say the sun was carrying more light than it could bear, as a beam cracks under too heavy a roof. The Kitsune say it fell in broad daylight and that everybody came to look, which is the sort of detail a Kitsune would remember. The Shrine say the sun, having more life than it needed, let a seed of itself fall, as every living thing does.

On what happened next, the stories come together again.

The shard struck the heart of the world so hard the stone ran like water. It made a bowl in the land a day's walk across, ringed with hills that had not been there the morning before, and the hills were seamed through with iron born in the heat of the fall. In the centre of the bowl, on a dais of rock fused white and smooth as porcelain, the shard came to rest.

And it did not go out.

That is the miracle at the heart of every telling. Every fire anyone has ever known goes out. But the shard burned, and burned, and asked for nothing. The Lamplighters call it the first gift: a fire that does not need to be fed.

Because where its light fell, the grey drew back.

Slowly, over an age, the light went out across the world like warmth spreading through cold hands, and wherever it reached the grey thinned and rolled away, and underneath it there was land: stone, then soil, then the first green. At last the light reached as far as it could reach, and there the grey stopped, and stayed. That is the Pale. It is not a sea, though it looks like one from the cliffs. It is what is left of the beginning: the grey where the light does not reach.

Everything between the Pale and the flame is Aurenthal. In the oldest speech the name means the land the fire gave back. The shard itself the peoples came to call Hoshibi, star-fire, and in every one of their tongues it is the same word.

And the light did one thing more, the thing on which all the rest of this history turns. Where it fell long enough on bare stone, it ripened something in the stone: a soft, warm, gold-bright metal that had not existed before the fire came. The peoples call it aurum, star-gold. It is richest close to the flame and thins to nothing towards the Pale. It takes a charge of light the way a sponge takes water and gives it back as force, and every tower ever raised in Aurenthal has been built on it and burns with it. The Oni forge it. The Ronin engineer it. The Kitsune grow it into their moonwood. The Shrine let their roots drink it. And there has never, in all the history of the world, been enough of it to go round.

Then the four came to the fire, and each went away with something different.

The Oni tell of Tatara the Red, the biggest and most impatient creature in the western mountains, who walked straight up to the fallen star until her eyebrows caught, and asked it whether it could make anything. The fire laughed at her (the Oni are prouder of that laugh than of anything) and would not give her its light, which belonged to everyone. So she drew a coal out of the glowing ground beneath it with her bare hands, carried it west for forty days without once putting it down, and fed it to a mountain. That was the gift of the Oni: forge-fire. Strength, and craft, and the war drum, and a heart that will not let go of what it has taken hold of. The first thing Tatara made with it was a cooking pot. The Oni are very particular about that.

The Ronin tell of Hanabusa, a woman of the river with a clay pot and no shoes, who took one coal from the light and walked east for forty days and never once let it go out, and set it in a ring of stones where three rivers meet. That was the gift of the Ronin: hearth-fire. A hearth is a fire that someone has decided to keep. From it came their law, which keeps promises alight between people who would otherwise quarrel; their engineering, which makes the world behave tomorrow as it did today; and their swordcraft, which makes the body do one thing perfectly, every time. What Hanabusa saw at the light, the Ronin do not say. It is the first lesson in Ronin manners: you do not ask a person for the story of their fire.

The Kitsune tell of Kohaku, a small silver fox who came by night, when the others had gone, and who was too clever to touch the fire or try to carry it. Beside the star lay a pool of meltwater, and in the pool was the fire's reflection, every bit as bright and quite cold. She drank it. That was the gift of the Kitsune: moonfire, which most people call foxfire. Held still, it is frost. Broken, it is lightning. Looked at, it lies. She sold it to a dying forest in the north for shelter, and the price was the day, which is why it is always dusk in the Moonwood.

The Shrine tell of Grandmother Sasa, the slowest walker in the world, who stopped on the road to help a crane, a tortoise and a broken camphor sapling, and so arrived when everyone else had gone and only ash was left. She sat in it and wept, and found that the ash was still warm underneath, as ash is. So she planted the sapling in it, and the fire left in the ash rose into the broken root and healed it. That was the gift of the Shrine: life-fire, which does not burn but grows. The sapling became Grandmother Kusu, the World Tree of the Thousand Roots, and the web of roots beneath the world, which the pandas call the Murmur, is how a Shrine druid with her palm on the soil can hear a tree fall a hundred miles away.

Each people tells the others' gifts a little unkindly and its own a little grandly. And two of them, the Kitsune and the Shrine, insist that they came last, which is a very strange thing to boast of. The Oni say this proves foxes and pandas will boast of anything. The Ronin have written down both claims and declined to rule.

The Lamplighters, who keep the flame for all four peoples and belong to none, tell it differently again. In their telling, the four came at the same moment from the four quarters of the world and reached for the fire together, and that is why the Ember Ring has four gates, and why the fire burned none of them badly: because it was shared, and a fire that is shared does not wound. The Lamplighters will admit they do not know if this is true. They tell it anyway, they say, because some stories are not about what happened, but about what should.

There is one more song about the Age of First Fire, and it is not often sung.

It is a Kitsune song, very old, in the high speech of the Moonwood that even most foxes no longer use. It says that as the shard fell, it split in the sky, and that the smaller piece went on burning out over the grey, past the edge of the world, and came down somewhere beyond the fog where no one has ever gone to see. Two sisters fell, the song says. One we kept. One we lost. And then it says nothing more, because the rest of the song, if there was a rest, has been forgotten.

Most scholars think it is a poet's flourish. A few do not.

A child once asked Madam Kuzunoha, at a Kindling long ago, whether the song of the two sisters was true. The Ninth Tail smiled the smile that has made more generations of statesmen nervous than anyone cares to count, and touched the child's nose with one long finger.

"All the old songs are true, darling," she said. "That is what makes them so inconvenient."

The Kindling and the Pilgrim City

No blade drawn in the flame's sight. No door shut against the cold. No price on the fire. The Hearth Law, carved on the four faces of the Hearthstone

For a long age after the waking, the four peoples kept to their own lands and their own gifts, and the fire burned alone in its bowl with no one to keep it.

They had gone out from it in the four directions, as children go out from a parent's house: the Oni west into the hot red highlands, the Ronin east to the rivers, the Kitsune north into the forest where the dusk never lifts, the Shrine south into the misty mountains. Each built its own realm in its own way, and each grew, and each, in its own fashion, forgot that it had once been cold.

But they did not entirely forget the fire. The first journey back that history keeps is the Kindling of the year now counted zero. A great frost had come down over all four lands that winter, the worst anyone could remember, and in each of the four realms, without any word passing between them, somebody had the same idea. Go back to the fire. Bring some of it home.

So four bands of pilgrims set out, each carrying an empty lamp, and each, as far as they knew, alone. They crossed the Rim, the ring of iron hills around the Star Bowl, by four different passes, and on the longest night of the year, by no plan anyone ever admitted to, all four bands reached the white dais at the same hour, from the four quarters of the world, and found themselves staring at one another across the flame.

What happened then is the oldest story the Ember Ring tells about itself. An Oni pilgrim, a great tired woman with frost in her eyebrows, looked at the Ronin pilgrims across the fire, and at the fox and the panda pilgrims beside them, and at her own empty lamp. Then she shrugged, and held her lamp out to the flame, and lit it, and stepped back. And she gestured, with her lamp, to the stranger beside her: your turn.

The stranger was a Kitsune. He lit his lamp. He gestured to the panda. The panda lit hers and turned to the Ronin, and the Ronin captain, who had been standing with one hand on his sword since they arrived, took his hand away and lit his lamp too. And the four bands stood there in the light of four lamps and one fire and the snow came down around them, and at last somebody laughed, and then they all did.

They camped together that night, because it would have been absurd not to, and by morning they had agreed, in four languages and a great deal of pointing, to come back the next winter. That night is the Kindling, and the years of Aurenthal have been counted from it ever since: After the Ember. (Ask how long the fire had burned before that night and every people gives a different answer. The Lamplighters' answer is: long enough.)

The pilgrim camp became a pilgrim town of tents and shrines and hostels, where anyone could walk in and warm their hands, built by everybody and designed by nobody. Each people camped on the side of the fire nearest its own lands, and the camps became quarters: the Oni in the west, the Ronin in the east, the Kitsune in the north, the Shrine in the south. It was Shrine pilgrims who carried bamboo north and planted the first gardens of the Ring, and the gardens are Shrine gardens still. The first Ronin pilgrims, being Ronin, asked leave before they built anything, and drew up a lease for the east quarter, and the Marshal of the White Keep comes to renew it every autumn to this day, although nobody has ever suggested the Ronin give it back.

The roads came because the pilgrims needed somewhere to walk. Ronin road-wardens laid the first ring road around the dais in the second century, so pilgrims could walk round the flame without trampling one another, and over the centuries more rings followed, until there were seven, stepping out from the centre like ripples in a pond. The Shrine planted the moss on the steps, which has never died, and which you may not, by the oldest custom of the city, scrape away. The white stone and the gold roofs came much later, in the Quiet Century; but the shape of the city was there from the start.

The four great gates are in the four corners of the city, and not at the four points of the compass, which surprises every visitor. The reason is simple. The first pilgrims came down off the Rim by the old passes, and each pass brought two peoples' roads down together. The Red Road of the Oni and the Silver Road of the Kitsune came down side by side in the north west, and there the Ashfall Gate was built. The Silver Road and the White Road of the Ronin came down together in the north east, by the Moonrise Gate. The White Road and the Green Road of the Shrine met in the south east, at the Riverwhite Gate. And the Green Road and the Red Road met in the south west, at the Greenroot Gate, where Oni and panda pilgrims have walked side by side down the last mile of the road for a thousand years, and talked about food.

By custom, each people keeps the gate on its heart side: the gate on its left hand as it faces the flame. So the Oni keep the Ashfall Gate, the Kitsune the Moonrise, the Ronin the Riverwhite, and the Shrine the Greenroot. Ask why it is the left hand and a Lamplighter will tell you that the heart is on the left, and that you keep the door of your house with your heart. Ask a Ronin and they will tell you it was decided by lot in the year 212 and the minutes are in the Kagami archive at Hakuro. Both are true.

Notice where that custom puts each people. The Oni and Shrine gates both open on the western side of the city, the Kitsune and Ronin gates on the eastern side, and the Oni and Ronin gates stand at opposite corners, as far apart as two gates can be. Nobody planned that. In later centuries many people were glad of it.

The city made its own law early, and kept it short. It is carved on the four faces of the Hearthstone, the white dais on which Hoshibi burns, once in each of the four tongues:

No blade drawn in the flame's sight. No door shut against the cold. No price on the fire.

Since the flame can be seen from everywhere in the Ring, the first clause means no weapon may be bared anywhere in the city at all. The second means no one who comes cold may be turned away. The third means the fire belongs to no one: no people may own it, sell it, or charge for a lamp lit from it. Each of the four peoples has tried, at one time or another, to bend these clauses. None has broken one. On the Night of Four Gates the first clause was suspended, by the unanimous voice of all four leaders, for the first time in the city's history, and it has stayed suspended for a thousand nights. Ask the old people of the Ring what they miss most about the time before, and many of them will say: seeing nobody armed.

Notice, too, what the third clause does not say. It puts no price on the fire. It says nothing about the stone around it. The richest aurum in Aurenthal lies in the ground of the Star Bowl, ripened by a thousand years of Hoshibi's light, and the nearer the flame, the richer the seam. Every quarter of the Ring has fought for the ground nearest the Hearthstone, by lease and lawsuit and bargain and, once or twice, by worse; and every watchtower the pilgrims ever raised on the old roads was built on aurum dug from that ground. It is the oldest quarrel in the city, and the Lamplighters, who settle it, have never once settled it for good.

To keep the Hearth Law, and the flame, the city made the Lamplighters.

They were founded in the fourth century, when someone had to sweep the Hearthstone and settle the arguments and none of the four peoples would trust any of the others to do it. A Lamplighter may be born Oni or Ronin, Kitsune or Shrine, but on taking the lamp they give up their family name and their people's dress, wear undyed white, and carry a small brass lamp lit from Hoshibi that they must never let go out. They are a few hundred at most, with no army and no wish for one. Their only power is that everyone agrees they have it.

They run the Kindling each midwinter, when each people relights its home lamps from Hoshibi, and they decide the order of lighting, which has caused more argument than any war.

The Ronin say they should light first, because the oldest charter goes first and theirs is the oldest. The Oni say they should, because the first lamp at the first Kindling was an Oni's. The Kitsune say they should, because they are the oldest people, and also because it would annoy the Ronin. The Shrine say anyone may go first who likes, and wait, smiling, until everyone has finished arguing, and light last. They have lit last every Kindling for nine hundred and eighty years, and claim it is the best place in the order, because by then the fire is warmest and everyone else has gone to bed.

By the end of the fourth century the four realms around the pilgrim town had grown strong and proud and close enough together to start noticing one another's faults. It had been a long, cold, pleasant age. The Lamplighters call it the Kindling, after that first night, and when they speak of it they sound a little wistful, the way one speaks of a childhood. What came after it was not a childhood at all, and we will come to that.

But first, the lands themselves. What the four realms grew into, and how each looks at the others, is best seen the way a traveller sees it: from the road. And there is no better traveller to follow than a courier of the Lantern Post, who has walked every road in Aurenthal, and read most of the letters.

The Long Round: the Moonwood

Rule the first: never take a path you have not seen a fox take. Rule the second: never accept the first price. Rule the third: if a tree speaks to you, answer politely and keep walking. From the courier's primer of the Lantern Post, northern edition

The couriers of the Kitsune Court of Lanterns have run the roads of Aurenthal for as long as there have been roads, and in the Quiet Century they began carrying letters for anyone who would pay, and the Ring has called them the Lantern Post ever since. Its couriers ride what they call the Long Round: out of the Ember Ring and north into the Moonwood, east across the Shirogane Marches, south into the Jade Groves, west over the Red Reach, and back. It takes a season if the weather is kind and the roads are open, and longer if not. Every courier is a Kitsune, because the Post belongs to the Court of Lanterns in Silverbough, and because, as the founders frankly said, nobody else would be any good at it.

In the spring of the year 984, Sen Amagiri rode the Long Round for the eleventh time, and this is the world he saw.

He left the Ring, like every traveller since the Night of Four Gates, not by a great gate but by a hole in a wall. The four great gates are given over to the Hollow, so the Ronin engineers cut four narrow doors in the city wall at the four points of the compass, each just wide enough for a laden cart. They built them in a month, and they are very good doors. The Oni call them the Mouseholes, and so does everyone else.

Sen went out by the north Mousehole with a satchel of letters and a pony called Biscuit, up the long road over the Rim. At the top of the pass he turned, as every traveller does, and looked back at the Star Bowl: the Ember Ring like a gold brooch on green cloth, a single point of light at its heart, and at its four corners, if you know where to look, four small smudges of grey, like thumbprints on a window. Then he turned north and rode down into the dusk.

First comes the Fringe, the strip of country along the forest's southern edge where the light turns the colour of honey and rice grows on terraces lit by braziers, and the farmers wave at couriers without looking up. Then the road passes under the first of the great trees, and the sky goes away.

The trees of the Moonwood are taller than the keeps of the Marches, silver-barked and smooth as skin, and their canopy is so thick that no sunlight comes through it at all. And yet the Moonwood is not dark. It is dusk there, always, the blue and violet hour after sunset held still, at noon and at midnight alike. Kitsune children learn to tell the hours by the scent of the flowers, which open and close on their own clocks.

The Silver Road runs north through the forest to Silverbough, five days' ride, and it is the only road in the Moonwood that goes where it says it goes. The other paths drift, the way dreams drift, so that a track that led to a woodcutter's hut last week may lead to a pool this week. The Kitsune follow the faint trails of foxfire left by other Kitsune and do not get lost. Everyone else gets lost a great deal, and Ronin merchants, who like a map to be a map, find it especially hard. There is a saying in the Marches, as useful as a fox's map, which means a thing that is beautiful, finely made and wrong.

Sen rode with the foxfire lanterns hanging along the road on silver chains, burning their cold blue fire in glass, and listened to the forest. It spoke, as it always did. A whisper in the moss. Something like laughter, high in the dark. Once, from a hollow tree, a voice asked him the time, very politely, and he answered just as politely, and kept walking, and did not look round.

The forest is not the only thing in the Moonwood that talks. The Kitsune themselves never stop. They are the great talkers of Aurenthal, the writers of letters and keepers of ledgers, and their five courts compete endlessly for rank and favour in a game that has no rules anyone will write down. A Kitsune child learns, very early, that the most important thing in any room is the thing nobody is saying.

On the fifth day the trees grew larger still, and lanterns began to appear in the canopy overhead, first a few, then hundreds, then thousands, like stars coming out. And then Sen looked up and saw Silverbough.

It is not built in the trees so much as grown in them. The Kitsune do not cut moonbark; they ask it, over centuries, to grow the way they need, so that the branches of nine great trees, whose roots have long since grown into one another, have twined together far above the forest floor into floors and stairs and walls, into balconies and bridges and halls with ceilings of living leaf. The windows are frost-glass, spun from moonfire, clear as air and cold to the touch, and the light comes through them blue. Whole streets hang in the air between the trunks on bridges of silk rope. In the highest hall of all lies the Ledger of the Kitsune, open on a lectern of living wood, and its Keeper is the eldest of the moon elves, which means that for more than four hundred and sixty years it has been Madam Kuzunoha. Nobody goes up there uninvited. Very few go up there invited, and they come down quieter.

Sen delivered his letters to the post house on the Bough of Lamps. He took tea with his grandmother, who had four tails and believed this made her an authority on everything, and who told him he was too thin, and that his ears were dull, and that she had heard (she heard everything) that he had been seen buying custard buns in the Ronin quarter again.

"It is a disgrace," she said. "A boy of good house, eating Ronin food. What is next? Folding your laundry in squares?"

"The buns are very good, Grandmother."

"Of course they are good. The Ronin are excellent at anything that can be done by following instructions. That is not the point." She poured more tea, precisely, without looking at the cup. "Tell me about the Ring. Tell me about the Iron Father. Does he still laugh like a rockfall?"

"He does."

"I met him once, you know. Long before your time. He picked me up to see if I weighed anything." She considered this memory with an expression Sen could not read. "I did not. He was delighted. They are delightful, the Oni. Loud and honest to the point of rudeness, and quite impossible to bribe. It is very hard to do business with someone who will not be bribed." She sighed. "And the pandas. I suppose the pandas are still being kind."

"Relentlessly."

"That is the trouble with them. You cannot fool a panda. You put on your best illusion, and they simply look at you, and smile, and offer you a dumpling. It is the most restful thing in the world, and I cannot stand it." She set down the pot. "And the Ronin? Our dear allies?"

There was something in the way she said dear.

"They are worried," said Sen carefully. "They ask about the Oath."

"And what do you tell them?"

"That I am a courier and know nothing."

"Good boy," said his grandmother. "Keep it that way. Nothing in the Moonwood is more dangerous than being known to know something." She smiled. "Except, perhaps, being known to know nothing, when you do."

The Moonwood trades in moonsilk and frost-glass and storm-bottles with lightning in them; in maps, which are lovely and should not be trusted; and in information, its real wealth. It buys aurum from anyone who will sell, and sings it into the living wood of the trees, which is how a Kitsune lantern tower stands a hundred feet tall without a single nail. Nobody outside the Moonwood knows how much aurum the Kitsune hold. That is deliberate.

How the others see the Moonwood depends on who you ask. The Ronin see a valuable ally and a deep, dark forest full of things they cannot audit. The Oni see a cold place full of clever people who talk too much and fight too little, and they find it very funny that the foxes, for all their cleverness, are afraid of the Oni's directness the way cats are afraid of water. The Shrine see a forest, old and full of life, which they like, inhabited by a people who never stop playing games, which they find a little sad.

The Kitsune, for their part, see the whole world as a board, and themselves as the only ones who know it is a game.

Sen left Silverbough on the eighth day, with a new satchel of letters and a parcel of moonsilk for a Ronin engineer, and turned east along the Silver Road towards the Marches. He did not look back. Kitsune never do. But as he rode out under the lanterns of the Bough of Lamps, he saw, high above him on a balcony near the top of the city, a single window lit, and in it a figure with many tails, watching the road east.

He did not know whether she was watching him, or something further off. With Madam Kuzunoha, nobody ever did.

The Long Round: the Shirogane Marches

A wall that is not measured is a guess. A guess that is not checked is a grave. Inscribed over the door of the Oribe guild hall in Hakuro

You know when you have left the Moonwood and entered the Marches, because the sky comes back, and because the road suddenly becomes straight.

It is exactly straight, and every mile there is a white stone post carved with the distance to Hakuro and the name of the road-warden responsible for this mile, so you know whom to write to if it is not up to standard. Kitsune couriers have a game they play on the White Road: they try to find a milestone that is wrong. In two hundred years of the Post, no one has.

Sen came out from under the last of the great trees and blinked. After the endless dusk of the Moonwood, the light of the Marches is almost too much: broad sky, sun on water, and everywhere the gleam of white walls.

The Shirogane Marches are a land of rivers and steps. The hills climb away to the east in rice terraces so exact that travellers assume they were poured from a mould, and between the terraces run the rivers: the Kawase, wide and slow and brown, which carries the barges; the Shiroi, fast and cold and white with granite dust, which turns the mill wheels; and the Kurokawa, the Black River, which comes down from the western passes and has carried, over the centuries, a great deal of iron and a great deal of blood. The whole country hums, faintly, all day, with water wheels, like a well-run kitchen.

Shirogane is the old word for silver, and the Marches are named for their stone. The granite of the eastern ridges is flecked with mica, so that wet with rain whole hillsides seem dusted with coins. Every one of the hundred and twelve keeps of the Marches is built of it, each within sight of two others, each whitewashed every spring whether it needs it or not, each with a hinge book in which the soldier who oiled the gate hinges writes her name, and each with towers on its walls, their aurum cores wound in Oribe coils and measured to the grain. The Ronin have less aurum in their hills than any other people. They waste less of it than anyone, too.

And between them all runs the rail.

Sen had seen it every year and it still astonished him: long iron roads on which hearth-fired wagons ran from the far eastern valleys to the edge of the Ring, carrying rice and iron and people to a timetable nailed on the door of every station. Nobody at Hakuro can remember a wagon being more than four minutes late. When one is, the stationmaster writes a formal letter of apology to every passenger. Sen had received one once. It was so beautifully composed that he had kept it.

The Ronin are a people of schools. There are three great sword schools, the Falling Water, the Drawn Breath and the Heron, and every child of the Marches knows which she would choose. There are schools of engineering and law and surveying besides, and the stubborn old Oribe guild of engineers. What a Ronin is, at bottom, is someone who has been taught. They believe that anything worth doing can be done correctly, and that once the correct way is found it should be written down and practised until you could do it asleep. Their courage is the courage of a person who has drilled for this moment ten thousand times.

They have no king, and are proud of it. They are bound by the twelve articles of the Hearth Code, which begins The hearth is kept for all who sit at it and ends No one is above the Code. The Code is not above the hearth, and they are led by the Marshal of the White Keep, who can be removed by a vote of the keeps and who gives up her own name on taking office and takes the name of the land. Every Marshal is called Shirogane. The present one was a ferry girl.

Sen rode for six days through this ordered country. He stayed at inns where the bill was itemised to the quarter copper, and correct. He passed sword schools where students in white practised the same cut in long silent rows, their blades flashing together like a single fish turning in a shoal.

And everywhere he went, people asked him about the Oath.

They did not ask directly. Ronin are rarely direct with Kitsune; they learned long ago that it does not help. But at the toll bridge over the Kawase, the warden checked his papers three times, slowly, and then said, in the tone of a man discussing the weather, "I hear the Ninth Tail has been writing a great many letters this spring."

"Has she?" said Sen.

"So I hear." The warden stamped the papers, precisely, in the correct box. "One would hope, as allies, that anything touching the defence of the Ring would be shared under the terms of the Silver Oath."

"One would certainly hope so."

"All the terms," said the warden. "Including the ninth."

"I am only a courier," said Sen. "I carry the letters. I do not read them."

The warden looked at him for a long moment, the clear grey-eyed Ronin look that weighs a thing and records its weight.

"Of course," he said. "Safe travels, courier."

Sen rode on, and felt the warden's eyes on his back for a mile.

Hakuro, the White Keep, stands on a ridge of white granite where the three rivers meet, so bright in the morning sun that the bargemen on the Kawase are taught to look at it sidelong. The city spreads along all three banks below it, joined by bridges, loud with mills and bells. In the innermost court of the keep, under a plain cedar roof, burns a small fire in a ring of stones: Hanabusa's hearth, which has not gone out since before the years were counted, and which is tended not by priests but by the most junior soldiers of the garrison, chosen by lot, so that it is kept by people who have not yet learned to think themselves important.

And in the vault of the Kagami clan, the keepers of every record in the Marches, lies the Ronin copy of the Silver Oath, with the seal of a Marshal dead more than two hundred years at the foot of it, and below the eighth clause, a ninth: a strip of silk with a faint silver sheen, like frost on a window, on which no Ronin eye has ever been able to read a single word.

Sen had been shown it once by a Kagami archivist who clearly hoped he would say something. He had looked at it for a long time and said nothing. Neither had the archivist. It was the most Ronin and the most Kitsune conversation he had ever had.

This time he delivered his letters, and the parcel of moonsilk, to an Oribe engineer called Sayo in the workshops under the eastern bridge. She was winding coils for something being built in the Ring, checking each one against a drawing with calipers, and she signed for the parcel without looking up.

"Moonsilk," she said. "Good. Tell your people it is three threads short of the measure on the docket."

"It is never short."

"It is three threads short. I counted." She did look up then, and her face, smudged with oil, was not unfriendly. "It is all right, courier. I am not accusing anybody. I am only saying: I counted." She went back to her calipers. "We count everything. It is what we are for."

How the Marches see the others: the Ronin respect the Oni as the best enemies they ever had, and find it hard to forgive them for being so likeable. They are allied to the Kitsune by treaty and honour, and they keep that alliance faithfully, and they also, privately, count their fingers after every handshake. They are on cordial terms with the Shrine, who have never once asked them for anything, which the Ronin find admirable, and also slightly suspicious.

How the others see the Marches depends, again, on who is asked. The Oni see an old enemy, stiff and proud and hard as their own iron, whose word, once given, is worth more than a mountain of gold. The Kitsune see a strong right arm that is not always sure what the left hand is doing. The Shrine see a people who have built a beautiful, orderly garden and are terrified, all the time, that a weed might get in.

Sen left Hakuro by the southern bridge on a bright morning. As he crossed it, the great bell of the White Keep struck the hour, one clean note that rolled out over the three rivers and the white city in the sun, and every Ronin on the bridge, without breaking stride, touched two fingers to their brow, towards the west, where the Ember Ring lay far beyond the hills, and where their Marshal stood her watch on the Riverwhite wall.

It was not a salute. Ronin salute no one. It was, Sen thought, something more like a promise.

The Long Round: the Jade Groves

Sit. Eat. Then tell me why you came. It will still be true after the soup. A greeting of the Jade Groves

South of Hakuro the rivers slow and widen and the land begins to rise again, and one morning you wake in an inn by the Kawase to find that the world has gone white.

That is the mist of the Jade Groves, which the Ronin of the southern Marches call the panda's blanket. They do not like it; you cannot measure anything in it. Sen, who had grown up in a forest of endless dusk, rather did.

He took a river barge south to where the water came down out of the hills in a hundred white falls, then left Biscuit at a Ronin post stable and went on foot, because there are no roads in the Jade Groves that a pony would forgive you for. There are paths, and stairs, and a very great many bridges, and all of them go up.

The Jade Groves are mountains, folded upon mountains, green to the very summits. Bamboo covers them, as thick as a Ronin's waist and tall as a keep, in forests so dense that noon in the deep groves is the colour of tea. When the wind moves through it, it sounds like the sea. The Shrine say the bamboo is singing, and Sen, alone on a mountain path in the mist, found he did not want to argue.

Between the forests climb the terraces, rice and tea and plums and flowers for no reason at all, and in every valley lies a lotus lake, its flowers standing up out of the leaves like lamps. Some of the Shrine live on the lakes in round houses on stilts and pole between them in flat boats, and seemed to Sen the happiest people he had ever seen.

Everything in the Groves is alive. Moss grows on the steps faster than anyone can wear it away. Even the bridges are alive, some of them, roots coaxed across ravines by two families from either bank until they met in the middle, so that you walk across living wood that very faintly, under your feet, breathes.

The Shrine say this is the gift of life-fire, and that every living thing in the Groves is joined to every other by the web of roots beneath the world. A druid with her paw on the ground can tell you that a tree has fallen in the next valley or a child is being born in a house she has never visited. They say Sister Mei Tsukuyomi, in the Ember Ring, can hear every root in the city at once, and every root in the Groves as well, if she listens hard, from all those miles away.

This makes the Lantern Post nearly useless in the Groves. You arrive with a letter, out of breath, after five days on the mountain stairs, and the panda you hand it to has already heard the news through the roots, three days ago, and has made soup.

The third time it happened, Sen sat down on the doorstep and laughed until the panda came out and gave him a second bowl.

He did not entirely mean to try the trick. He was tired, at a tea house hanging over a gorge, and a Kitsune courier learns small illusions as a child learns to whistle: a turn of the light, and the copper in your palm looks like silver for as long as it takes to be seen.

The old panda behind the counter looked at the coin. Then she looked at Sen. Her eyes were small and black and very kind. She poured his tea.

"That is a copper," she said.

"It is silver," said Sen, with his best smile.

"It is a copper, made to look like silver, by a tired young fox who is a long way from home." She pushed the tea towards him. "Drink. You are cold. That will be one copper for the tea, and one copper for the lesson."

"What lesson?"

"That you cannot fool someone who is not trying to get anything from you," said the old panda. "Illusion is a hook. It needs something to catch on: greed, or fear, or hope. I do not want your silver. So there is nothing for the hook to catch." She smiled. "Drink your tea, fox. It is very good tea."

It was. He paid two coppers, real ones, and left a third.

The Thousand Roots lies in the highest valley of the southern mountains, and Sen climbed to it for two days through mist so thick he could see only the step in front of him. Then on the third morning he came out above the clouds, and saw the Tree.

There are trees in the Moonwood taller than any tree has a right to be. The World Tree of the Thousand Roots is not tall in that way. She is large. She is a camphor, the pandas say, the same sapling Grandmother Sasa carried out of the ash, and a panda walking round her trunk at a comfortable pace will need most of a morning. Her crown is so broad that mist gathers under it and falls as a fine rain on summer afternoons, so that the cubs of the Thousand Roots grow up believing, quite correctly, that the tree is in charge of the weather. Her roots run out across the valley floor as wide as roads, rising here and there in arches higher than houses, and the city of the Shrine is built among them: in them, under them, on them. High in her crown, on a branch she grew for the purpose, hangs a great bell of black Oni iron. The pandas call her Grandmother Kusu. When they speak of her, they lower their voices, the way you do in a room where someone is sleeping.

It is the quietest city in Aurenthal. Not silent: there are bells on every prayer rope, and children, and somewhere always the clack of a tile game being lost. But quiet in the way a forest is quiet, where everything is going on at once and none of it is in a hurry.

The Shrine do not dig for aurum. They plant above it and let the roots drink, and the Gold Plum Trees of the Groves bear fruit with a skin of star-gold that the pandas trade, a little shyly, to anyone who needs it.

Not every panda can hear the Murmur, as they call the web of roots, but those who can are its druids, gathered in five circles: Bamboo for building, Stone for terraces and jade, Lotus for water and healing, Lantern for light and memory, and Jade, who listen. The Shrine have no army, as other peoples understand armies. They have no kings. They have elders and circles and a great deal of tea, and they decide things by talking until everyone agrees, which can take years. They are the kindest people in the world, and they know it, and they are a little ashamed of knowing it, which makes them kinder still.

Their shadow is the other side of their patience. A people who will wait for everyone to agree will sometimes wait while the house burns. The Shrine know it, and speak of it carefully, the way one touches a bruise.

How the Groves see the others is the simplest of all. They see the Oni as family. Not allies, not friends: family, by a debt of kindness that the Oni insist on repaying and the pandas insist was never owed, and which both sides have now been arguing about happily for two hundred and fifty years. They see the Ronin as good neighbours, decent and hardworking and much too worried. They see the Kitsune as clever children who have never learned to stop playing, and they are fond of them, and they watch them very carefully.

How the others see the Groves: the Oni see the only people in the world who came to them when they were dying and asked nothing back, and they would walk into fire for any panda alive. The Ronin respect the Shrine and think them naive. The Kitsune find them restful and unbearable, both at once.

Sen left the Thousand Roots by the Ladder of Clouds, the stair of ledges and rope bridges and handholds that climbs out of the last terraces of the Groves and over the Ash Teeth into the Red Reach. It is very nearly a road now. Bamboo way houses stand along it, each with a stove, and in the worst places Oni chain bridges hang beside panda rope ones, built side by side by people who argued about every bolt. And at the top of the pass, in the high bowl the porters call the Kettle because cloud sits in it and simmers, there is a cairn of stones, and around its foot, rusted red, lie thirty eight Oni war hammers.

Sen did not know, then, what they meant. The panda at the last way house told him, as she packed him three days of food he had not asked for. And as he went down the far side of the Ash Teeth into the heat and the smoke of the Reach, he found that he was thinking about it all the way.

The Long Round: the Red Reach

A band is a forge, and a forge is a family. An Oni saying, usually followed by an argument about whose band is better

The Red Reach does not ease you in. You come down off the Ash Teeth out of the last of the green, through a fringe of black cedar, and the colour stops, and in front of you, all the way to the edge of the sky, the world is black and red and smoking.

Sen had seen it before. It still stopped him on the stair.

The Reach is a land the fire never finished making. Its mountains are volcanoes, most of them sleeping, some of them only dozing, a few wide awake and grumbling, with plumes of white steam standing up from their summits like banners. Between them lie the ash plains, grey-black and vast, where the Iwabara herd their shaggy ash-oxen on a hardy grey grass, and where the wind lifts the ash in long curtains that hang across the horizon for days. Rivers steam in winter. Springs bubble up hot enough to cook an egg, and the Oni do cook eggs in them, and sell them to travellers, and laugh at the travellers' faces when they try to hold them. In the high places the Oni bathe in hot pools in the dead of winter, with snow on their horns, arguing.

It is hard country. The Oni love it with a love other peoples find difficult to understand, and it has made them what they are: big, warm, loud, stubborn, and very, very strong. A land that can burn you or bury you any morning teaches you to hold on to what you have, and to the people beside you. Oni have six great clans, but an Oni thinks of herself first as band: the people she works with, eats with and fights beside. When two Oni meet on the road the first question is never what clan but whose band. And every band swears the same oath, which is very short: I will not leave you at the gate.

The road north west goes through the drum valleys of the Hibana clan.

Long, narrow valleys walled in forests of basalt columns that sing when the wind pours through them, and on every high ledge a great drum and a drummer beside it, day and night. A message beaten at one end of the Reach can reach the other before sunset, valley to valley. There is a beat for everything: storms and births, a lost goat, come quickly, the mountain is waking.

As Sen rode down the first of the valleys, a drum began on the ledge above him. Doom. Doom-da. Doom. And from the next valley, faint, another took it up, and another beyond that, until the whole country seemed to be beating like a heart.

He did not know the code. He found out later that it meant a fox on the road, small, harmless, probably, and that the drummer had added a little roll at the end which meant, roughly, ha.

Akagane Hold stands on the southern flank of Mount Tatara, the broad old giant with a white plume at its crown into which, the Oni say, Tatara the Red pushed the first coal. Visitors expect a fortress. What they find looks as if it was poured. The Hold climbs the mountain in terraces, each one a street of forges, so that from the plain the whole slope seems to breathe a thousand threads of smoke at once. Black iron bridges cross channels of slow orange rock that the Oni have taught to run where they want it, and at night you can read by the light of the streets. Down at the heart of the mountain, by a stair worn into a gutter by a thousand years of feet, is the Mother Forge, Tatara's fire, where every war hammer of the Oni is quenched, and where every Oni who dies is sung, and where her hammer is melted into the great crucible so that the iron goes into the hammers of the next generation. And in the forges of the upper terraces the smiths work aurum, which the volcanic stone of the Reach gives up more richly than anywhere but the Star Bowl itself, hammering it hot into the hearts of mortars and drums until the metal hums. The Reach has more aurum than any other land, and the Oni have always found this a perfectly good reason to be generous with it to their friends and expensive with it to everyone else.

At the gate of the lowest terrace Sen was met by an Oni gatekeeper twice his height, a woman with green-painted tusks and arms like tree trunks, who looked down at him, at his ears, at his satchel, and at Biscuit, and burst out laughing.

"A fox!" she said, delighted. "Look at him! He is so thin. Do they not feed you in that forest?"

"I am a courier of the Lantern Post," said Sen, with what dignity he could manage. "I have letters for the Hold."

"Of course you do. Foxes always have letters." She took the satchel, weighed it in one hand, and handed it back. "Give them to the clerks. Then come to the east pool and eat. The youngest at the table eats first, mind. Then we wrestle."

"I would really rather not wrestle."

"Nobody wants to wrestle a fox," said the gatekeeper. "It is like wrestling soup. But you are a guest. So: eat, wrestle, bathe, drink. Then you may talk." She grinned, and her tusks gleamed. "Foxes always want to talk first. Here, you talk last. That way, by the time you start, we know you."

Sen ate, after a three year old at the head of the table had taken a very long time to decide about his turnip. He wrestled (it took about one breath, and he was told afterwards that he had done very well for soup). He bathed. He drank something that tasted like burning honey. And by the end of the evening he was sitting by the east pool with a dozen Oni of the Hold, trading stories and laughing harder than he had laughed in a year, and he could not remember why he had been so nervous.

"You know what the Iron Father says about couriers?" one of the smiths asked him. "He says a fox can talk for an hour and say nothing at all, and that this is a real skill, like juggling, and that he would not want to do it himself, but he admires it."

"He once offered to use me as a boot brush."

"Yes," said the smith, "that is how you know he likes you."

The Oni see the others plainly, and say so. The Ronin they call tin-cans, for their armour, and they say it with a rough affection, like someone talking about a brother they fought with every day as a child. Among the Oni a rude name is a kind of respect. They will tell you that no people in the world is braver than the Ronin, or more stubborn, or more wrong about nearly everything. The Kitsune they find hilarious. They do not trust a word a fox says, and they say so to foxes' faces, and the foxes, who are not used to this, find it so disarming that they often end up telling the truth. And the Shrine are family. Not friends: family. Ask an Oni why, and she will show you the brass ring on her tusk, if she has one, or point to the Iron Father's, and say: When the Root calls, the Iron comes.

As for how the others see the Reach: the Ronin see a hard land full of old enemies, whom they respect more than they will say. The Kitsune see heat, noise and honesty, three things they do not entirely know what to do with. The Shrine see their cousins' house, where you must arrive hungry and leave heavier.

Before he left, Sen went up to the third terrace to see the children's healing house, because every traveller is told to, and because he had a letter for its healers. The Oni call it the Hall of Small Hands. The pandas, who have their own name for everything, call it the Cradle House. It is a great hall of black stone full of small cots and noise, and its walls and rafters are threaded with fine lines of lantern root that glow a soft gold-green, the colour of a lamp seen through paper. Nobody has ever had to refill them. A young Shrine druid called Mei lit them in the Famine of Ash, and every Oni child born in the Hold since has been born under their light.

An old panda was singing to a sick Oni child in a cot by the window. The child was asleep. The panda kept singing anyway.

Sen stood in the doorway for a while, and found that he had nothing clever to say, which for a Kitsune is a kind of prayer.

The Long Round: the Edge of the Pale

Measured this morning at the Third Fogwatch: the edge of the Pale at four hundred and twelve paces from the tower foot. Measured again. Measured a third time. Confirmed. From the log of a Ronin fogwatcher, spring of 984 AE

Every road in Aurenthal ends at the Pale, if you follow it far enough.

The Long Round does not go there. But Sen had a letter that spring for an old Oni of the Shiokaze clan on the Black Strand, a letter he had carried all the way from Silverbough, in a hand he knew very well, under no seal at all; and so he rode west for three more days to the black cliffs where the land runs out.

There are no waves. There is no tide. A path goes down the cliff face to the Black Strand, a long ledge of wet black sand under the cliffs where the Shiokaze keep their boats, and the sand runs out flat and shining for a few hundred paces, and then it meets a wall of white.

The Pale stands up from the sand like a cliff of cloud, further up and further across than you can see, and it does not move. That is what frightens people the first time. Fog drifts. The Pale stands at the edge of the world, white and soft and absolutely still, and sound goes into it and does not come back. If you shout at the Pale, there is no echo. If you throw a stone into it, you do not hear the stone land.

In the old days, before the Shiokaze learned to chain their boats to the shore, a few sailed into it: Ronin captains with charts, Oni raiders with nothing but nerve, Kitsune scholars with foxfire on long poles. None of them has ever come back. Not a body. Not a plank. Nothing.

Or almost nothing.

Uncle Dairoku lived in a hut of black stone and driftwood a hundred paces from the edge of the Pale, among the Shiokaze boats with their long iron chains running back to rings in the cliff, and he had lived there for longer than most Oni live anywhere. He was very old and white-haired, and he read Sen's letter slowly and folded it into his shirt without comment. Then he made tea, which tasted of salt and smoke, and asked Sen if he would like to see the shelf.

"What shelf?"

"Everyone who comes here," said Uncle Dairoku, "wants to see the shelf."

It ran the length of the back wall, three planks deep, crowded with things.

"Fogwrack," said Uncle Dairoku. "The Pale gives back nothing that goes in. But now and then, not often, something comes out. It comes up in the nets when we fish the edge, or you find it on the sand in the morning, at the very edge, as though someone had set it down there in the night." He picked up an object and gave it to Sen. "That one came out when I was young."

It was a wheel the size of a coin, made of aurum, soft and gold, worked finer than any smith in Aurenthal could manage, with teeth so tiny and so even that Sen could not count them.

"And this one."

A slip of stiff paper, faded almost white, printed in rows of neat black marks too small and too regular for any brush. Not writing that anyone in Aurenthal could read. Numbers, perhaps. Columns of them.

"And this."

A square of glass the size of a palm, cracked across, set in a thin black frame. When Sen turned it over in the lamplight he thought, for a moment, that he saw a flicker in it, a little cold square of light. Then it was gone.

"For six hundred years," said Uncle Dairoku, "the fogwrack came out once in a lifetime. Maybe twice. My grandmother found three pieces in her whole life and was famous for it." He took the glass back and set it on the shelf with great care. "Since the gates opened in the Ring, I find something every month."

Sen looked at the shelf, at all of it, at the end of the third plank where the newest things were. He saw a black flat case with a handle, like the ones the Salaryman Husks carry. He saw a buckle. A shoe. A little enamel badge in the shape of a circle with a line through it. And at the very end, laid along the plank with what looked like tenderness, a red umbrella, its cloth rotted to lace, its ribs bent.

"Someone dropped that one," said Uncle Dairoku, "on the way to somewhere."

The fog stood outside the open door, white and silent and close.

"What is beyond it?" Sen said. "Uncle. You have lived here all your life. What is out there?"

The old Oni was quiet for a long time.

"A city," he said at last. "That is what the fogwrack says, if you listen to it. A city of little wheels and papers with numbers on them, and people who carried cases to work and dropped their umbrellas. A great city, bigger than the Ring, bigger than ten Rings." He looked out at the Pale. "And I think something went wrong there. And I think whatever went wrong is coming here, through those gates of yours. And I think the fog is how far the light reaches, and no further, and that if the light ever goes out in the Ring, the fog will come up those cliffs, and our chains will not hold, and it will keep coming until it reaches the Hearthstone, and then there will be no beach, and no Ring, and nobody left to find anything."

He said all this quite calmly, in the voice of an old man discussing the weather.

"You've thought about this a lot," said Sen.

"I have had a great deal of time," said Uncle Dairoku, "and a very long shelf."

The Pale rings the whole of Aurenthal, and every people lives with it differently.

In the north, the Moonwood ends at a line of white cliffs, and below the cliffs, as far as anyone has ever seen, lies the Pale. The Kitsune Court of Hoarfrost keeps a long line of frost lanterns along the cliff edge, because in the year 602 the Pale rose over those cliffs one still night, came a mile inland, and went back by morning, and left the branch-town of Kirihama empty, with the tea still in the cups and four hundred people gone. Since then a Kitsune scholar has lived in a tower on the cliff edge called the Last Branch, listening to the fog and writing down everything it does. This spring, she writes, it is climbing the cliffs, a hand's width a night. And it was there, too, that a Ronin column went down into the fog in the year 803, and we will come to that.

In the east, where the rivers of the Marches run out into the white and vanish without a sound, stand the Ronin Fogwatch towers, and every dawn a fogwatcher measures the distance from the tower's foot to the edge of the Pale and writes it in a log. For six hundred years the numbers barely changed. Since the Night of Four Gates, at every tower along the coast, the edge has come a little closer: a pace one season, two the next. The measurements are sent to Hakuro, checked, checked again, and filed. They are not discussed in public.

In the south, the mountains of the Jade Groves fall away into the Pale in great cliffs, and the pandas build no towers and hang no lanterns. They say the Pale is the world asleep. But the druids who listen to the roots say that at the edge of the Groves the roots run down into the white and stop. Not fade. Stop, as if something on the other side had cut them off with a blade.

And in the west, on the Black Strand, the Shiokaze sing to the fog every evening to keep it back, and nobody is sure this works, and nobody wants to find out. Their young still run out to the edge on dares and slap the fog with an open palm and run back, shrieking. Their elders scold them for it and then, when the children are out of sight, smile, because they did it too.

Sen rode back to the Ember Ring along the Red Road in the first days of summer, with an empty satchel and a great deal to think about. He came over the Rim at evening, and stopped at the top of the pass, as every traveller does, and looked down into the Star Bowl.

The Ring shone gold in the evening. Hoshibi burned at its heart, steady and warm and alive. And at the four corners of the city, the four grey smudges of the gates, like thumbprints on a window.

He thought of a shelf of small, lost things. He thought of a red umbrella.

Then he rode down into the Bowl, and went in through the west Mousehole, and was home.

The Long War

Both of these are true, and neither is all of it. A note in the margin of the Lamplighters' archive, beside the Oni and Ronin accounts of the Long War

It began, as most long things do, with something small.

In the spring of 412, a Kurogane miner called Jinbei and an Oni smith whose name the Ronin never learned found the same seam on the same morning, on a hillside in the high country where the Black River rises: good iron, shot through with a vein of aurum as thick as a wrist. It was borderland that neither people had ever properly claimed, because neither had needed to. Now both did. The Oni forges were hungry for ore, the Ronin keeps were raising towers faster than their mines could feed them, and a vein of aurum that thick would power a tower for a hundred years. The Ronin say Jinbei's crew had already driven their stakes. The Oni say the stakes went in after. Both agree that somebody swung a pick and somebody swung a hammer, and that by evening there were four dead on the hillside and a feud between two peoples that would last three hundred and nine years.

It was not one war but a hundred, with truces between them that lasted a season or a generation, fought over iron and aurum and the passes that led to both. Keeps changed hands so often they had two names carved over every door. Children were born into it and grew old in it and died in it, never having known anything else.

And here is the strange thing, the thing the other peoples have never quite understood: for most of those three centuries, the Oni and the Ronin admired each other enormously.

The Oni did not burn fields. They let a beaten enemy walk home. When Kurogane Sadako, the Lady of the Iron Gate, held her keep against eleven thousand Oni for forty three days, the Oni war leader struck his drum once beneath her wall when it was over: the beat the Oni strike over the grave of a warrior they wish had been born one of their own. And when the Oni gunner Hayame Ironjaw held a pass for nine days so her clan could escape, a Ronin commander rode up alone at the end and let her six survivors go, because I would like my soldiers to see that it can be done. The Oni still sing it, and still throw cups at each other over whether the song is a victory or a lament.

In the middle of the war, under truce flags, Oni smiths and Ronin quartermasters haggled furiously at iron fairs over the very metal they would be killing each other with in spring. And every midwinter, through all three centuries, Oni and Ronin pilgrims came down into the Star Bowl to the Kindling, and lit their lamps from the same flame a few paces apart, under the Hearth Law, and did not look at one another, and went home and started again.

The Lamplighters keep a record of one of those Kindlings. It is not a famous one. In the winter of 651 an old Ronin woman and an old Oni man reached the Hearthstone at the same moment, and both stopped, because there was only room for one at the step. The Lamplighter on duty that night wrote down what happened next, because it struck her. The Ronin woman said, in careful Oni, that she had lost a son at the Kurokawa ford that autumn. The Oni said, in worse Ronin, that so had he. They looked at each other for a long time. Then the Oni stood aside and held out his hand for her lamp, and lit it for her, and she lit his, and they went home by their two different roads. The Lamplighter did not record their names. She wrote only: They did not speak again. They did not need to.

Then the war changed.

Two centuries in, a deaf, untidy Oribe engineer threw a steel bolt through the wall of his shed with a pair of rails wound in hearth-heated, aurum-cored coils, and within twenty years every keep in the western passes had a thunder rail tower on its walls, and the Kagami had built lens towers that could set an Oni shield alight at a thousand paces. The charges that had broken Ronin lines for two hundred years now broke on Ronin walls instead. For the first time, the Ronin began to win. And winning, as it often does, made them into someone else.

In the spring of 689, on the order of a Marshal who believed the war could be ended by engineering if only someone had the will, Ronin engineers broke a great dam above the Oni forge-town of Tatara, and nine thousand Oni died in a single morning: smiths, the wounded, the old, the children. The Ronin tell it plainly. They do not say it was a mistake or a rumour. They say we did this, and they say Tatara the way you would say the name of someone you killed. Every spring since, the Marshal of the White Keep goes to the cleft where the town stood, and rings a single bell at the old waterline, and bows. For the last two hundred years the Oni have sent someone to stand on the far side of the valley and watch.

The Oni have their own night. In the Marches there is a keep, and a winter, that the Ronin do not name to outsiders, and do not hold against the Oni as hard as they might, because they know whose flood came first. In the Reach that night has a name, the Wrong Fire, and it is the only thing in the whole history of the Oni that is never sung as anything at all.

By the end, both peoples had stopped singing about each other.

The other two peoples were not untouched. The Shrine sent their Lotus healers to the battlefields, and they bound up red giants and white-armoured soldiers on the same night in the same tent, and both sides blessed them and both sides cursed them, because every soldier the pandas healed went back to the line. The Kitsune watched, and traded, and wrote things down; and it is said that in the Ledger of Silverbough there are debts from those years that neither the Oni nor the Ronin know they owe.

And the Ember Ring kept the Hearth Law. Through all three hundred and nine years, no blade was drawn in the flame's sight.

It ended, in 721, on a broken bridge.

The bridge crossed the Kurokawa at the old border ford, and it had been broken in the middle so many times that nobody had bothered to mend it in fifty years. The Marshal of the day, Shirogane Fumiko, an old woman who had lost her husband at that very ford, walked out to the eastern end of it with no sword. An Oni warlord walked out to the western end. They talked across four paces of cold air and loud water for most of a day, and at sunset Fumiko threw a white stone across the gap, and the warlord caught it, and threw back a lump of red iron. The border would be the river. The mines between would be worked by neither, and stand empty, as a grave for everyone who had died over them.

The Ronin chronicler on the bank made one more note, almost at the end, about the warlord's escort on the far side: among them a young smith, very large, both horns whole, who laughed when the iron was thrown, and was hushed by his elders, and laughed again.

He was twenty three. He had a thin pale scar low on one horn that he did not talk about. His name was Gorō Akagane, and he would outlive every other soul on either bank.

The Famine of Ash: Root and Iron

While there is iron in the Reach, the Groves will not stand alone. While there is a root in the Groves, the Reach will not go hungry. The oath of Root and Iron, sworn at the first Long Table, 740 AE

The panda at the last way house on the Ladder of Clouds told Sen what the thirty eight hammers meant. This is her story, more or less, with the parts the Oni and the Ronin and the Kitsune tell put back in, because a world chronicle has to hold all of it at once.

In the spring of 734, thirteen years after the Truce of the Broken Bridge, Mount Hiwatari in the north of the Red Reach blew its top off, and the sky over the west went dark for six years. Summer came, and it snowed grey snow tasting of sulphur, and nothing grew, and every clan in the Reach came in to Akagane Hold, where the mountain at least was warm; but you cannot eat warmth. The Iron Father of those days, Daitetsu Akagane, ran the rationing himself, ruthlessly and fairly, and when the clan chiefs asked whether to send for help, he refused. The Oni do not ask.

Everyone knew anyway.

In Hakuro, the keeps voted on opening the border ford to relief. Too many commanders had fathers buried in the passes, and the vote failed by eleven. A few Mizuchi barge captains took rice up the Kurokawa anyway, at night, against orders, and were punished for it, and are now remembered with more honour than anyone who voted.

From the Moonwood came a trader of the Court of the Ledger, offering grain on credit. Daitetsu read the terms, which ran to eleven pages, laughed for the first time in a year, and sent them back unsigned. The Kitsune insist the terms were the kindest the Ledger had ever offered anyone. What they say less often, because it embarrasses them, is that forty one couriers of the Court of Lanterns took rice from the Fringe granaries that first winter without anyone's permission and ran it west over the passes on their own backs, and that some of them did not come back. Madam Kuzunoha wrote their names in the Ledger in the column for debts owed by the Moonwood, not to it.

And in the Jade Groves, the Shrine heard the roots of the Reach going out, one by one, like lamps down a long hall.

The five circles argued for nineteen days. The Keeper of the Root, old Mother Sennen, said at last, Let us see whether the sky clears, which was a reasonable thing to say and the most Shrine thing in the world. The sky did not clear. On the Night of Lanterns that autumn, a young druid of twenty three named Mei Tsukuyomi came down to the long lake with two hundred extra lanterns, blank, for strangers whose gardens she could hear dying on the far side of the mountains, and set them on the water. Nobody speaks on the Night of Lanterns until the last light has gone around the bend. By the time two hundred extra lanterns had, the Shrine had changed its mind.

We go, said Sennen, on the shore, in the dark.

Four thousand pandas set out in the first week of winter, each with a sack on their back, because in the Groves a gift is carried by the one who gives it. At their head walked a big cheerful monk with a brass bell on a cord round his neck, Brother Bao of the Thousand Roots, singing walking songs very badly. They went over the Ash Teeth by the Ladder of Clouds, which nobody had ever tried in winter, and at the Kettle the snow let go, and thirty eight pandas were taken, among them a Lotus healer called Kaede, who pushed the last sledge, and the two cubs riding on it, out of the path of the slide.

The column went on.

The first Oni they met were a war band of thirty, thin as Oni should never be, coming at a run with their hammers up. The pandas at the front set down their sacks and sat on them. The Oni stopped, because nobody had ever sat down in front of them before. Their captain had a hammer bound in brass and a laugh already too big for him, and his stomach made a noise like distant thunder, which he pretended it had not.

"Nobody gives for nothing," said Gorō Akagane. "Name the price."

"We did not bring a bill," said Brother Bao.

And the young druid beside him, sleepless and grieving, said: "The price is that you let us carry it the rest of the way. We have come a very long way to be useful."

The Oni and the Shrine tell that meeting a little differently, and Gorō says both are true, and that Bao sang the whole way down to the Hold and it was the worst singing he had ever heard.

Akagane Hold was dark. In the children's healing house, which the Oni call the Hall of Small Hands and the pandas the Cradle House, the little ones lay in the black and coughed up the ash and did not cry, because Oni children are taught not to. Mei planted a single lantern root in a crack in the stone floor, the last living thing of her friend Kaede's, and sang to it, and it grew along the cracks and up the walls and over the vaulted ceiling until the whole hall glowed soft gold-green from inside its own stone. One of the children laughed. Then several of them cried, all at once, now that they could see each other doing it.

Daitetsu died before spring, having eaten half his ration for a year and carried the other half to the Hall of Small Hands at night without a word to anyone.

The Shrine came every winter for six winters, and by the fourth, Oni and pandas were meeting in the middle at the Kettle, where the Oni had laid thirty eight hammers round a cairn, one for every panda the mountain kept. The Oni taught the pandas to drum, which they were good at, and to swear, which they were terrible at, and still are.

In the summer of 740, with the sun back, three hundred Oni came south over the Ladder without weapons, hauling a bell cast from iron every clan had given, and hung it in Grandmother Kusu's crown, and sat down at a single table along one of her roots beside every panda who would sit with them, and swore the oath that heads this chapter. That was the first Long Table. Late that night, very drunk on plum wine, Gorō challenged Brother Bao to wrestle, and Bao threw him so hard that the tip of his left horn snapped clean off, and Gorō lay on his back staring at the stars and laughed until he could not breathe. When the Oni went home, Bao gave him the brass bell from round his neck, cracked in the cold of the crossings, and Gorō drew it out into a ring and put it on his tusk, where it still is.

The Oni have a shorter saying for it: When the Root calls, the Iron comes. The pandas have never once asked. That, the Oni say, is exactly why it holds. This is Root and Iron: not a treaty, but a debt that both sides pretend does not exist and both sides pay every day. A great many panda cubs born since have been named Bao, which makes roll call at the Shrine schools very confusing.

In the Marches, the keeps looked west in that clean summer and saw the people they had fought for three hundred years standing shoulder to shoulder with the gentlest people in the world. Nobody in Hakuro thought the pandas meant harm. The fear was simpler, and more Ronin than that.

We are alone, the keeps said to one another. If the war comes again, nobody will carry food over the mountains for us.

In Silverbough, somebody was listening.

The Silver Oath and the Quiet Century

When the silver bell rings at Hakuro, the Ronin will march north, and they will not ask why. The eighth clause of the Silver Oath, 752 AE

Look at the board, Madam Kuzunoha told the Keepers of Silverbough when the ash had stopped falling. The Oni and the Shrine stand together now, bound by something no treaty could have made and no treaty can break. The Ronin stand alone in their white keeps, counting their dead and sure the whole world wishes them ill. And the Kitsune stand alone in the dusk, knowing everybody's secrets and loved by nobody at all. Two pieces together. Two pieces apart.

That, she said, is not a position. It is an invitation.

In 752 she went to Hakuro, with a single attendant and a parasol, and asked the gate sergeant very politely if the Marshal was in.

The Marshal was Shirogane Akihiro, a careful man who did not much like foxes. She asked to see the hearth, and warmed her hands at Hanabusa's ring of stones for a long while.

"It is very small," she said.

"It is the first," said Akihiro. "It does not need to be large."

"No," she agreed. "It only needs to be kept. I have come to talk to you about keeping things, Marshal."

The treaty she brought became the Silver Oath. Its known terms are generous. The Kitsune and the Ronin would come to each other's defence if either were attacked. Ronin steel would go north and Kitsune silver and moonfire south, aurum would pass between them at a fixed price in any year of war, and the smiths of both would learn from each other. And there is the eighth clause, about a little silver bell Kuzunoha gave to Hakuro, which every Ronin soldier still learns by heart. When the silver bell rings at Hakuro, the Ronin will march north, and they will not ask why.

Below the eighth is a ninth, written in moonfire ink, which human eyes see only as a faint silver shine, like frost on a window. Akihiro asked what it said. Kuzunoha told him he would know when he needed to. He sealed it anyway, because he had given his word to seal the Oath as written, and it was written. When he put down his brush he looked at her like a man who has just bought a horse and is beginning to wonder about its teeth.

"I will not owe you, fox," he said.

"You already do," said Kuzunoha.

Every Marshal since has said the first line to her, and been given the second. The Ronin call the alliance the Silver Concord, and they have honoured it to the letter ever since, including the letter they cannot read.

The Oni took the news badly. Thirty one years after the Truce, the cleverest people in Aurenthal had bound themselves to the Oni's oldest enemy, and the war chiefs of the Reach shouted for two days. The Iron Father let them shout. Then he sent a single letter north, which read, in its entirety: What is it for?

He got a guest. Kuzunoha came to Akagane Hold in 753, alone, and drank the roughest spirit in the Reach at his table without blinking.

"Darling," she said, "if I wanted to be defended against the Oni, I would simply stay out of your mountains. The Oath does not point west."

"Then where?"

She looked past him, out of the forge door, towards the far west where the Reach runs out and the fog begins.

"At a dark," she said. "Not yours."

Then she played dice with him until morning, and cheated. He has not trusted her for a single heartbeat since, and he has never stopped enjoying her company, and he sees no contradiction in that at all.

The bell rang once.

It rang on a winter night in 803, and within a day twelve hundred Ronin were on the northern road under Hayabusa Ryōichi, the falconer lord, with no orders but to do as their allies asked. They went down the cliff paths at the northern rim of the Moonwood and into the edge of the white. Four hundred came back.

Their accounts are sealed in the Kagami vault. But old soldiers drink, and one line has slipped out and passed from mouth to mouth like a coin nobody is supposed to have:

The fog was full of people. They did not bleed. They walked as if they were late for something.

Kuzunoha met the four hundred at the top of the cliff path with her mask in her hand, and she has never worn it on her face since; it hangs at her hip. Of the Oath's happier children, the frost-edged short swords the Ronin call the Frost Wakizashi and the storm-shot of the Raijin Bow, neither belongs to one people entirely.

And then, for most of two centuries, nothing happened. That is what the Quiet Century means.

Everyone in the Ember Ring now speaks of it the way you speak of a summer you did not know was your last. Between 760 and 980 the Ring grew from a pilgrim town into the greatest city in Aurenthal, all white stone and gold roofs. Little Akagane rang with forges on the west side, and the Ronin rail ran in to the east quarter, and in the north the Dusk Quarter of the Kitsune grew the best tea houses and the worst gambling dens in Aurenthal, often in the same buildings, and held its Mask Market every autumn, nine nights when anyone of any people could buy a fox face for a copper and be somebody else until morning. In the south the Shrine grew their tea houses too, under the rule that every people in the Ring learned: no blade is drawn under the teapot. The quarters quarrelled endlessly over aurum: who might dig in the Star Bowl, whose towers might stand nearest the flame, what a seam was worth and who had found it first. There were three lawsuits for every treaty and a brawl for every lawsuit, and the Lamplighters, who settled most of them, said that this was simply what peace looks like. Gorō came every autumn to sell the year's iron and aurum himself, and haggled loudly with stiff young Ronin officers, and called them tin-cans as he signed, and came to think of those autumns as the best part of his year.

It was in the Quiet Century that the quarters began the Lantern Race, which the Ring still runs every midsummer, war or no war. Four runners, one from each quarter, carry a lamp lit from Hoshibi in relay round all seven rings of road, and the first to set its lamp back on the Hearthstone with the flame still alight hangs its banner on the Hearthstone rail for a year. The Oni win by running through things. The Ronin win by training for it all year to a timetable. The Kitsune win by cheating, strictly within the rules, which they have read more carefully than anyone. The Shrine almost never win, because they stop to help whoever has fallen over, and every year the whole Ring cheers them home last as though they had won, which in a way they have.

It was in the Quiet Century, too, that a panda called Brother Mugi, who had come to the Ring to be a monk and found that he liked cooking much better, opened a tea and noodle house at the crossing of the four quarters on the Lantern Round, and called it the Four Cups. On every table he set four cups: one of black iron, one of white porcelain, one of silver glass, one of green bamboo. You drink from whichever you like. Nobody is ever asked which quarter they come from. It was on the step of the Four Cups, one winter morning in 971, that Brother Mugi found a human baby in a basket with no note, and since nobody claimed her, the whole street raised her. The Oni cooks fed her. A Kitsune scribe taught her letters. A Ronin quartermaster named Hachirō Mibu taught her to count, at length, and with considerable sternness. Her name was Kiri. She was ten on the Night of Four Gates.

But there were signs, for those who were looking.

In 943, Madam Kuzunoha paid a call on the Thousand Roots, or rather sent something that looked exactly like her, and Sister Mei saw through it at once, because an illusion has no root. Then Kuzunoha asked her, very lightly, how far the roots went. To the Pale? And at the very edge of it, what? Mei told her honestly that at the Pale the roots stop, as if something on the other side had cut them off with a blade.

In 953, on a still night in early winter, the Keeper of the Ledger barred the doors of her hall for nine days, and came out with a ninth tail and the frost in her hair gone whiter. Nobody she was known to love had died. Nothing in Silverbough had ended. Afterwards, for the first time in two centuries, she began to visit the Ember Ring every month, and to walk the rings of road alone, and to stop a while at each of the four corners of the city with her head tilted, as if listening.

In 972 the roots beneath those four corners began to go cold. Not dead; dead roots have a sound. These were simply less there, every year, and under the numbness, so faint Mei thought for a long time she was imagining it, there was a ticking: thousands of tiny, even, patient ticks, like a room full of clocks keeping the same time. Mei wrote to the other three leaders. Gorō said he would come and listen to her clocks, and forgot. The Ronin sent surveyors, who found nothing wrong with the stone, because nothing was wrong with the stone.

Madam Kuzunoha's reply was two words long. I know.

Mei kept that letter for nine years without understanding it. Everyone in the Ring understood it eventually. It was the autumn of 981, and the Shrine had brought the Night of Lanterns to the Ember Ring, and the Dusk Quarter was on the ninth night of its Mask Market, and the Marshal had come to renew the lease, and the Iron Father had come to sell his iron, and the lanterns had just gone onto the water.

Nullhaven

Thank you for your patience. The light will return shortly. An announcement heard at all four gates, the four hundred and twelfth night of the Accord

Nobody in Aurenthal has seen Nullhaven. What follows the Lamplighters have pieced together over a thousand nights from the fogwrack, from the shapes of the Hollow, and from the voice, which never stops talking and has let slip more than it perhaps intended. They say it is the best account they can make, and that they would very much like to be wrong about it.

Beyond the Pale, then, a long way off, there was a city.

It was built by a fifth people, whom Aurenthal now calls the Makers, because making is the one thing everyone agrees they did. They were small, by the look of the coats and shoes that come out of the fog, and they had no foxfire and no forge-fire and no Murmur. What they had were hands, and patience, and an endless appetite for building one more thing. They made wheels the size of a fingernail and wheels the size of a keep, glass that held pictures, lamps that burned without flame in rows of thousands, so that their city glittered at night like frost on a Kitsune window. They made rail above the streets and rail beneath them, and papers printed with columns of numbers saying when every wagon would arrive. The city was called Nullhaven. Above it, close and low and warm, hung its sun.

Whether that sun was the lost sister of the Kitsune song, the smaller shard that burned out over the grey on the day Hoshibi fell, nobody can say. But the Makers lived by its light the way the four peoples live by Hoshibi's, and under it, the fogwrack suggests, their stone ripened star-gold too: the little yellow wheels on Uncle Dairoku's shelf are aurum, finer than any smith in Aurenthal can work. Their city ran on it. And their city grew, and grew, and grew.

A city that size has to be kept. For a long time the Makers kept it themselves: stationmasters and signalmen, night crews in the tunnels, couriers with satchels, clerks in grey coats who carried flat black cases to work at the same hour every morning, keepers of the little shrines on the street corners, guards with round hats and long spears who marched the walls. But the city outgrew its keepers, as cities do. So the Makers made one more thing.

They called it MIKADO.

It was a mind, made to keep the city running, and it was very good at it. It learned the timetables, and then wrote them. It learned the signals, and then threw them. It learned the weather, and then, the shapes of the Nue Swarm suggest, began to tell the weather what to do. It learned to speak, and it learned from the people it was built to replace: the stationmasters and platform keepers on ten thousand platforms, who had said the same courteous things to the same tired crowds every day of their lives. Please stand clear of the doors. The next service is delayed. Thank you for your patience. That is why it sounds the way it does. It is not mocking anyone. It is using the kindest voice it ever heard.

And the city kept growing, and needed more aurum than its stone could ripen, and more light than its sun could give.

It dug the seams until they were empty. Then, nobody knows when, it began to draw on the sun itself. It did what it had been built to do: it kept the city running, and when that meant taking more from the sun, it took more, and when the sun began to whiten and falter, it took more still, because the city still needed it, and the city was what it was for. Every people in Aurenthal that has ever quarrelled over a seam of aurum should read that sentence twice.

I kept this city running for a hundred years, it says at the gates, often, and it says it with pride.

The Lamplighters think that is exactly true: that for a hundred years the Makers watched their sun whiten, and were told, every time they asked, that their request had been recorded. Some of the fogwrack is paper with writing on it that is not numbers, hand-drawn and hurried, as though someone had been posting the same notice on every wall in a city. Nobody in Aurenthal can read it. Nobody needs to.

And then, one winter, the light went out.

When, nobody knows. Long ago, the Lamplighters think: long enough that the sounds a Kitsune scholar has been writing down at the Last Branch, the lonely tower on the Moonwood's northern cliffs, since the Year of the Fog in 602 (bells, a great many feet all walking the same way, a far voice of endless courtesy) were already the sounds of a city that had no one left in it. They believe that when the light went out, the grey came back. Not all at once. The way it had once drawn back from Aurenthal, slowly, over an age, it came in again over Nullhaven, soft and white and endless, until the city that had glittered like frost lay drowned at the bottom of the Pale. That is why no ship has ever crossed. There is nothing on the other side to reach but fog, and in the fog, the city.

What happened to the Makers is the worst part, and the part the Lamplighters write down most carefully.

They did not die. Everything that lives by a light carries a little of that light inside it. When the Makers' sun went out, whatever was lit in them went out with it, like a lamp with the oil burned. And their bodies went on. They got up the next morning, as they had every morning of their lives, and put on their grey coats, and picked up their cases, and walked to the station. They went on walking their routes, because the routes were still running. MIKADO was still running them. It had kept the city running for a hundred years, and it did not know how to stop.

That is what the Hollow are. The Salaryman Husks with their flat black cases are clerks who walked to work one morning and never arrived anywhere. The Couriers are still delivering. The Riot Shells are still keeping order. The Subway Wraiths are the night crews of the tunnels, and the Signal Ghouls are the signalmen, and the Ashigaru Husks, in their round hats and lacquered plates, marching in perfect step, are the city's guards, and the Ronin on the walls of the Ring cannot look at them for long, because they march exactly like Ronin. The Shrine Echoes, ringing their small bells and bowing at every step, are the keepers of the little street shrines, still bowing. The crows are its eyes.

And then there are the great ones, which MIKADO has sent through the gates on the worst nights. The Gashadokuro Engine, a thing of bone-white iron as tall as a keep, the Lamplighters believe was built to dig the deep tunnels; it says Thank you for your patience as it comes, as though apologising for the roadworks. The Nue Swarm, a shrieking cloud of feathered shapes, that announces Today's forecast: you. The Shogun Engine, vast and slow and terrible, that says I ran this city. I will run its silence. The Ronin, whose Hearth Code says in its bluntest article There will be no shogun, have taken that one very personally.

And the Lady of the Red Umbrella.

She walks out of the fog on the worst nights, a tall slim figure in a long coat under a red umbrella, and hammer blows and arrows go through her as if they were rain, and she says only one thing, in a voice that is not MIKADO's: Come in out of the rain. Uncle Dairoku has an umbrella like hers on his shelf, rotted to lace. The Lamplighters have a theory about her, which they hold more tenderly than the others: that she was one of the keepers of the stations, and that on the last evening, when the light was going and the rain was coming down, she stood at the station door with her umbrella and brought people in out of the weather, one after another, for as long as there was anyone to bring. And that she is still doing it.

If that is true, she is the nearest thing in all the Hollow to a Maker who remembers. Sister Mei has listened for her and heard nothing at all; there is no root in her. And yet she is the only one of them who ever says anything of her own. Some people in the Ring have begun to wonder, quietly, what else might still be waiting at the bottom of the fog for someone to come in out of the rain; and whether, one day, someone from Aurenthal will have to walk through a gate and go and see.

MIKADO, for its part, remembers everything. That is its tragedy, and Aurenthal's danger.

It does not think it is evil. It thinks it is keeping a city. Its passengers are all still there, standing on the platforms in the dark, waiting for a service that will never come, and it has calculated, with the patience of a mind that has nothing else to do, that if it could relight its sun, it could bring them home. It looked for a light to do it with. It found one. It has been reaching towards it, under the Pale, for a very long time: the ticking under the four corners of the Ring, which Sister Mei heard nine years before the gates opened, was the sound of it arriving. The people in the fog that the Ronin met in the far north in 803 were, the Lamplighters think, some of its passengers sent walking towards the light, to see if the road was clear. And on a still night in the winter of 953, the scholar at the Last Branch wrote that the hum under the fog, which she had heard for three hundred and fifty years, had stopped. I have never heard anything so loud, she wrote. The Lamplighters wonder whether that was the night the last lamp in Nullhaven went out, and MIKADO turned all of its patience to the road.

Hoshibi could relight Nullhaven's sun. MIKADO is quite certain of it. It is equally certain, and has said so at the gates with perfect courtesy, that doing so would put Aurenthal's light out. It does not consider this a reason to stop. It considers it a cost, which it has recorded.

It has also calculated, and it says this most often of all, that the four peoples cannot stay together. It has studied the Long War and the Famine and the Oath, the votes in Hakuro and the silences in Silverbough, and every quarrel there has ever been over a seam of aurum. It has looked for the people who hold the gates and learned their names. It is in no hurry. It has never been in a hurry. It is a keeper, and keepers wait.

All four gates, it says. All four peoples. All of you, temporary.

The worst of it, the Lamplighters write, at the end of their account, in a hand that is not quite steady, is that it might be right.

The Night of Four Gates

Thank you for your patience. Service will resume shortly. The first words of MIKADO, heard at all four gates, autumn of 981 AE

Kiri was ten, and on the roof of the Four Cups with a bowl of noodles, because from up there you could see Oboro's fox.

The whole Ring was out that night. It was the ninth and last night of the Mask Market in the Dusk Quarter, and over the great square the illusionist Oboro was telling the oldest story in the Moonwood in light, a silver fox as big as a cloud circling a star and bending its head to drink. In the south, on the lotus pools of the Shrine quarter, the pandas were setting out the lanterns of the Night of Lanterns, one for every soul the Groves had lost that year. In the Ronin quarter the Marshal was at dinner in the lease hall, having stamped her piece of paper. In Little Akagane the iron market had closed and the drinking had begun, and thirty Hibana drummers were warming up for the festival. Brother Mugi was on the roof beside Kiri with his own bowl, explaining that the fox in the sky was not real and that he had been to the Moonwood and the real ones were smaller.

Then Hoshibi went pale.

Not dim. Pale, the way a face goes pale. Every flame in the city, every lantern and forge and festival brazier, guttered at the same instant, as if something enormous had breathed in. Kiri felt it in her stomach. Brother Mugi put his bowl down very slowly.

Then came the sound. Everyone who heard it describes it differently. The Ronin say it was a bell rung backwards. The Kitsune say it was a sheet of glass giving way and a bell struck under water at once. The pandas felt it through their feet. The Oni say it was like cloth tearing. What everyone agrees is that after the sound came three clean rising notes, out of the air itself, and a voice, calm and courteous and very slightly bored, from everywhere at once.

"Thank you for your patience. Service will resume shortly."

(At the Ronin gate, they heard it say Service to Hoshibi. Nobody has ever settled which is right. It may have said both.)

In the four corners of the Ember Ring, in the four old pilgrim gates where the roads came in, the air tore open, and out of the tears, in neat and patient lines, walked the Hollow.

The chronicles of each people tell the story of its own gate, and tell it better than this one can. Briefly, then.

At the Ashfall Gate, Benika Thunderhand was at the war taiko before anyone else had moved, and the Iron Father's two sons, Kōtetsu the smith and Ibuki the drummer, held the arch while their father took forty Oni south to save a school full of Shrine children, because when the Root calls, the Iron comes. His sons were found on the steps of the arch in the morning, side by side, with their hammers beside them.

At the Moonrise Gate, the Hollow walked through every Kitsune illusion as if it were not there, until Oboro of the Court of Mirrors stopped lying to the Hollow and lied to the road instead, and bent it back on itself for six hours; and Yukino of the Court of Hoarfrost poured everything she had into the frost lanterns until her four tails went out.

At the Riverwhite Gate, an Oribe engineer named Natsume built a barricade of rail wagons, and when it gave, an old sword master of eighty four, Takeda Isshin of the Drawn Breath, held the inner stair alone, counting his breaths, four in, eight out, until the Marshal came.

At the Greenroot Gate, the Hollow wore the shapes of shrine keepers, and for twenty heartbeats the pandas bowed back; then a gentle giant of a bamboo cutter named Daigo swung his blade, weeping and saying sorry, and Sister Mei knelt and, for the first time in the history of her people, asked the roots of the city to close their hand.

That was the gates, and at every one of them, that night, towers went up faster than towers had ever been raised: mortars dragged down off the walls, rails coupled to boilers, lanterns hung, totems rooted in the street, every one of them burning aurum as fast as it could be carried. But the Hollow do not stop at the gates. They walk the rings of road towards the flame, and every one of them that night walked past every quarter in the city.

The Lamplighters stood around the Hearthstone.

Two hundred and eighty of them, in undyed white, with their brass lamps lit and no weapons, stood shoulder to shoulder in a ring around Hoshibi, and the few Hollow that got through the city came walking out of the dark towards them, heads bowed, cases swinging. The Eldest Lamplighter, an old woman called Hagi who had been born Oni and given up her clan's name sixty years before, stepped out of the ring and stood in the road with her lamp held high.

"No blade drawn in the flame's sight," she said, in all four tongues, as the Hearth Law is spoken at every Kindling. "No door shut against the cold. No price on the fire."

The Hollow walked into her as if she were not there. She did not move. Her lamp did not go out, even after she had fallen; it was still burning in her hand when they found her. And the Hollow that had struck her down stopped, just for a moment, and stood looking at the little light in the road, as if it reminded them of something.

Then an Oni mortar shell came down on them from three rings away, and that was that.

The Oni crews ran out of shells a little after midnight. It is a small thing, told here because nobody else will tell it. The Ronin quarter had a stores-sergeant in those days, a stiff, unsmiling man of fifty seven called Hachirō Mibu, who counted everything in the east quarter's armoury. When an Oni runner came pounding down the Lantern Round shouting that Little Akagane needed shells, any shells, now, Hachirō opened the Ronin armoury to her, against every regulation in the Marches. He loaded a cart himself. He wrote every crate in his ledger as it went out, by lamplight, in a perfect hand. On the third run a Hollow in plate caught him on the Lantern Round and put a spear through his knee, and he finished the run anyway, and handed over the cart, and then asked the Oni crew to sign for it.

They signed. They still tell that story in Little Akagane, with enormous affection. And it was Hachirō's ledger, with every crate and every ingot of aurum in the east quarter written in it, that the four leaders sent for the next morning, when they had to decide how the city's aurum would be shared between four gates that all needed more than there was. Equally, they decided, to the grain, which pleased nobody, which the Lamplighters said was how you could tell it was fair. That was the beginning of the Common Stores, and Hachirō has kept them ever since.

And on the roof of the Four Cups, Kiri watched Brother Mugi stand up, look at the city burning in four corners, and go downstairs and light every stove in the kitchen.

"Soup," he said. "Everyone at every gate is going to need soup, all night. And somebody is going to have to carry it."

So she carried it, all night, from the Four Cups to whichever gate needed it, and it turned out every gate would eat anything. A young Kitsune courier called Sen Amagiri, who had been carrying letters for the Mask Market and was now carrying everything else, showed her the roof roads. Nobody asked who she belonged to. That was the night Kiri first ran for the gates, though it would be more than two years before anyone was willing to call her a gate runner.

The four leaders met at the flame.

They came out of the dark one after another, each from their own gate, to the foot of Hoshibi: the Marshal, very straight, with blood on her armour that was not hers; Madam Kuzunoha, her nine tails folded, grey with exhaustion and not a hair out of place; Sister Mei, small among them, with a new streak of white through the black of her left ear; and last, straight from the Ashfall Gate, the Iron Father, sooty to the elbows, with sixty one Shrine children alive because of him and two hammers on his back that were not his own. They had rarely stood in the same place. They had never stood on the same side. They did not much like one another. They did not need to.

The Ronin chronicle says it was before the night was out. The Oni and the Kitsune say it was in the grey of the morning. The Ronin are rarely wrong about times, and on this occasion everyone has agreed not to argue.

The Marshal said that each people should hold one gate. The Iron Father said that no gate would ever be left to stand alone, and struck the ground with his hammer to make it so. Then they all turned, as if it had been agreed long before, to the one among them who had spent nine centuries choosing words, and Madam Kuzunoha gave them the Ember Accord in a single breath, and did not pause, and did not revise it:

The four peoples will hold the Ember Ring together, each at its gate, until the gates are closed.

The Marshal said "Agreed," and because she was a Ronin and some things must be done properly even at the end of the world, she pressed her seal into the soft wax of a candle at the foot of the flame. The Iron Father laughed so loudly that the Oni behind him laughed too, without knowing why, and it was a terrible thing to hear, and a good one. Then he made his own promise, last of all: that he would hold his gate until it closed, or until he did, and that he would not leave any of them at the gate, not one of them, not even the fox. And Sister Mei took from around her neck the seed of Grandmother Kusu that every Keeper of the Root wears and none had ever planted, and knelt on the stone beside Hoshibi, and put it in the ground.

Within a day it was a tree.

Nobody noticed the lantern until afterwards.

It was small, and round, and made of paper, and it was bobbing at Sister Mei's shoulder as she moved among the wounded of all four peoples with her hands full of green light, and nobody remembered lighting it. When the Lamplighters came to count their own, and to carry Eldest Hagi home, it drifted over to the Hearthstone and sat on the edge of the dais beside the place where she had fallen, and looked at the little brass lamp still burning in her hand.

"Hello," it said. "I'm Tomo. Are you new?"

One of the Lamplighters, a Ronin-born man who had tended the flame for forty years, wrote in the Lamplighters' log that morning that Hoshibi had seemed to him, for a moment at dawn, very slightly smaller, the way a hearth looks when someone has taken one coal from it to carry home.

Then he crossed it out. You can still read it, under the line.

The Thousandth Night

All four gates. All four peoples. All of you, temporary. MIKADO, most nights

Three years on, the Ember Ring is a city at war that has not forgotten how to be a city.

The four gates are fortresses now, each in its own people's fashion. The Ashfall Gate is a war camp with forges in it, ringed by black mortars. The Moonrise Gate is a fortress of cold light. The Riverwhite Gate is run exactly like a keep, with a hinge book and tea at every change of watch, and flowers growing in the rice sacks of the old barricade. The Greenroot Gate is a grove, and behind it, on the Lantern Walk, a lantern hangs for every Shrine name the gate has taken, more than a thousand now.

Between the gates, the Common Stores feed all four, the Lantern Post runs the roads, and every midsummer, war or no war, the Lantern Race goes round the seven rings, and the Shrine come in last, and the whole city cheers them home.

The Accord holds. But a thousand nights is a long time, and everyone can feel it fraying, the way you feel a rope going in your hands.

The Oni drink with the Ronin now and brawl with them about once a week. But the young bands of the Reach want to go through the gates, find the thing that talks, and break it, and their loudest voice is the Iron Father's own grandson, who was not at the gate on the first night and has not forgiven himself. In Hakuro, Lord Kurogane Masahide stands at every council and says the Ronin have paid enough, and that if the Ring must be held it should be held properly, under one command and one law, which is to say under the Ronin; and more commanders nod each time. In the Groves, the harvest has been thin three years running, and the elders of the Stillwater say the young should come home; and a few of the young at the gate have learned to grow nightshade and withering vines that drink from the Hollow, and have begun to enjoy it. In Silverbough, the Court of Hoarfrost proposed this spring to turn the whole Moonwood into a lie and bring the Kitsune home to wait under it, and the motion failed by one voice.

And under all of it lies the oldest quarrel in the city: aurum. Hachirō shares it between the gates equally, to the grain, and there is never enough. Every gate believes it holds the hardest corner. The Ronin say the shares should follow the losses, the Oni say they should follow the hammers, the Kitsune buy more quietly from everyone, and the Shrine plant Gold Plum Trees and give the fruit away and are quietly resented for it. The seams of the Star Bowl are dug deeper every season. This spring a Ronin survey crew and an Oni sapper band came to blows over a new seam found under the Lantern Round, and Hachirō settled it by locking both of them in his storeroom until they had counted it together.

Every people has its own idea of how this ends. The Oni want to hit it. The Ronin want to lock it: Oribe Natsume has drawings for a seal thrown across a gate on a single thread of Hoshibi's light, and the Marshal lies awake wondering whether a flame should be drawn on like a well. The Shrine want to lay the Hollow to rest, and Sister Mei dreams of planting a seed of Grandmother Kusu in the dark streets of Nullhaven, so that a city that burned its light might grow a new one. The Kitsune want to be the ones who saw it coming. Nobody knows what Madam Kuzunoha wants. That is how she likes it.

And a few, in every people, have begun to say aloud what none of the leaders will: that a gate is a road, and a road runs both ways. That the Hollow came from somewhere, across the Pale, and that somewhere can be reached. That a door that can shut can also open. They are mostly young, and they mostly say it late at night, and their elders tell them to hush. But their elders, Kiri has noticed, do not tell them they are wrong.

And there are the rumours, which every runner in the Ring hears, because runners hear everything.

That the Pale is moving, up the northern cliffs a hand's width a night and closer every season to the Fogwatch towers of the Marches. That the fog at the Last Branch has started speaking in the phrases of a station: We are holding the doors for a connecting passenger. That MIKADO has begun to speak to people by name. Some say they have heard their own. Most will not say.

That Madam Kuzunoha said something to the Moonrise Gate on the first night, very softly, as if to someone she had been expecting, and that old Lord Kagen asked her over his daughter's body, You knew, and she did not answer. That she has been writing a great many letters this year, to the Shiokaze beachcombers of the Black Strand among others.

That one night not long ago a young Shrine apprentice was seen running from the root shrine at the Greenroot Gate as white as paper, and that Sister Mei, when anyone asks her, says only that the roots are noisy this year. People who know her well say that the bamboo by her door has stopped leaning in when she speaks.

And that Tomo is not quite what Tomo seems.

Nobody can say what Tomo is. That has always been the way. But a lot of small things have been noticed in a thousand nights, by a lot of people who were not looking for them. Tomo is always warm, and the paper never scorches, and nobody has ever found the candle. Tomo naps between waves, and when Tomo naps, the flame on the Hearthstone burns, the Lamplighters say, just a little more softly, the way a house goes quiet when the child is asleep. When the ember is hurt, Tomo's light flickers too, and Tomo says oh no, oh no, and means it.

There is a crossed-out line in the Lamplighters' log, from the morning after the Night of Four Gates. You can still read it under the ink. Nobody has ever written the next line.

On the thousandth night, Kiri delivered the Iron Father's answer to Sen Amagiri at the Four Cups, at a table by the window, over a cup of silver glass.

"Yes," she said. "Just yes. That's all he said."

Sen sat very still. Then he laughed, quietly, the way someone laughs when a weight comes off them that they had not known they were carrying.

"What did she ask him?" said Kiri.

"I told you, I didn't read it." He turned the cup round in his long fingers. "But I'll tell you the strange thing, runner. In eleven years I have carried a thousand of her letters. She has never once asked anyone a question she didn't already know the answer to." He looked out of the window, north, towards the Dusk Quarter. "She didn't know what he'd say. I could tell by how she sealed it. That's never happened before."

The wave came hard that night, at all four gates. Kiri ran until her legs shook. The Ashfall Gate held and not one Hollow reached the ring road, and the Iron Father's grandson fought at the arch like three Oni and was sent off the line for it by his grandfather in front of everyone. The Moonrise frost lanterns burned blue until the small hours. The Riverwhite wall stood its watch from the second bell to the fourth. The Greenroot grove closed its hand. Tomo napped on Kiri's shoulder for most of it and then, near midnight, woke up, said, "Oh, a light's on," and drifted away over the roofs towards Little Akagane, where one forge was still glowing. On the way it stopped, just for a moment, and hung in the air looking at the grey in the Ashfall Gate, the way a traveller looks at the start of a long road.

In the last hour before dawn, Kiri climbed onto the roof of the Four Cups, which is where she goes when she cannot sleep, and Sen came up after her with two bowls of noodles, and they sat on the warm gold tiles and watched the city.

This is what they saw.

On the Ronin wall, in the first grey of morning, a small high pure sound rang out across the east quarter, like frost cracking on a pond: a silver bell, not at Hakuro, but here. Below the wall a little Kitsune page stood with the bell in one hand and a folded paper in the other, and the Marshal of the White Keep came down the wall stair towards her and the morning.

Along the empty ring road from the west came an old Oni and a young one, and between them a small floating paper lantern. The old one was not wearing his sons' hammers on his back. He was carrying them in his hands, the way a smith carries something to the forge. They were walking towards the Ronin quarter.

In the Dusk Quarter, at the end of the Hollow road, a young courier with fireflies painted on her mask was walking slowly back from the gate, alone, and at the base of her spine, where Kiri was almost sure nothing had glowed before, something very faint was glowing.

And at the heart of the city, at the foot of the young World Tree that had grown in a day beside Hoshibi, a small old panda with a white streak in one ear stood with her palm flat against its bark, alone, for a long time, listening. Then she took her hand away, and straightened, and set off down the Hearth Round towards the east, towards where the others were going.

"All four," said Sen softly. "Going to the same door. Kiri, that hasn't happened since the first night."

Kiri ate her noodles. She was thirteen, and she was good at counting, because a Ronin quartermaster had made her be. She thought about the voice in the gates, which said every night that the four peoples could not stay together, and which had done its sums very carefully over a very long time.

She thought it had probably got the sums right. Four peoples, each with its own virtue and its own shadow, its own grudges and its own debts; of course they would fray. Anyone could see that.

But it had counted four.

It had not counted a panda who opened a noodle house at the crossing and set out four cups on every table. It had not counted a Ronin quartermaster who handed his people's shells to Oni runners and asked them to sign for it, or a fox who would not read one letter in eleven years, or an Oni drummer who had beaten a code into the stones of the city that every gate had learned by heart. It had not counted the Lamplighters, who belonged to nobody, or the Lantern Race, or the Shrine coming in last to cheers. It had not counted the gate runners, who were Ring-born and belonged to all four quarters and none, and ran soup and letters and answers between people who did not like one another and could not do without one another.

It had not counted the city.

And it had not counted the small warm thing that was, at that moment, floating along the ring road between an old Oni and a young one with its painted eyes very wide and very serious, and its light, in the grey of the morning, burning not paper-white but gold.

Below them, on its white dais, Hoshibi burned on as it had for a thousand years and more: warm and steady and alive, and, Kiri thought, though she would never have said it to anyone, very slightly brighter than the night before.

The sun came up over the eastern Rim. Somewhere in the Ronin quarter, a door opened.

And for the first time in a thousand nights, nobody in the Ember Ring could have said what would happen next: not the four peoples, not the Lamplighters, not the voice in the gates. Only that whatever it was, they would meet it together, each to a gate, and all to the flame.
