Red Iron: the Oni of the Red Reach

The Coal in Tatara's Hands

Ask an Oni child where her people come from and she will hold up both hands, palms out, and show you the burn.

There is no burn. There has not been one for a thousand years and more. But every Oni child is taught to show it anyway, because every Oni alive is descended from a pair of hands that carried fire for forty days, and the Oni have never been a people to let a good scar go to waste.

Ishiba the Ash-Singer has told the story more times than anyone living. She is blind now, and older than the Iron Father, and she tells it from an upturned forge bucket with her white eyes turned toward the nearest fire. She does not like to be interrupted. She is interrupted every single time.

"Before the star fell," Ishiba says, "we were big, and we were cold, and that was all we were."

In those days the Oni were grey-hided giants in the caves of the western mountains, strong enough to tear a pine out by the root and with nothing whatever to do with it afterwards. They died young, and nobody sang about it, because there was nothing yet to sing.

Then the sky split. A star came down like a lantern dropped from a great height, and the whole world turned gold for a night, and in the morning a fire was burning at the heart of the land. It is called Hoshibi now. The Oni had no name for it then. They had no word bigger than bright.

Four peoples walked toward that light, the Ash-Singers say. The humans of the east came with their heads bowed and asked how to keep a home warm and orderly, and were given the hearth. The moon elves of the north came softly, by night, and asked for cleverness, and were given foxfire. The pandas of the south asked for nothing at all, and so were given the most, which was life.

And Tatara the Red, the biggest and most impatient creature in the western mountains, did not bow, and did not kneel, and did not come by night. She walked straight up to the fallen star until her hide blistered and her eyebrows caught, and looked it up and down, and said:

"You are very bright. Can you make anything?"

I can make anything, said the fire. What will you make with me?

"Whatever my people need," said Tatara.

That is a large promise.

"We are a large people."

And the fire laughed. The Oni say that before Tatara the fire had never laughed, and that every crackle in every hearth on Aurenthal since is the fire remembering the joke.

It would not give her its light, which belonged to everyone. But beneath the light, where the star had driven itself deep into the earth, there was heat: red, slow, patient heat, the kind that does not dazzle but changes things. Tatara reached into the glowing ground with her bare hands and drew out a single coal the size of a child's head, and turned around, and started walking west.

It took her forty days. On the third a human offered her a pair of iron tongs. On the ninth a fox elf offered to carry the coal for her, for a very small consideration, to be settled later, and she laughed so hard she nearly dropped it. On the twentieth a panda offered her a broad green leaf to wrap it in, and that one she almost took, because it was kindly meant. To each of them she said the same thing.

"If I put it down, I will have to pick it up again."

"There," Ishiba always says, and raps her stick on the bucket. "The best thing about us and the worst thing about us, in one breath. Remember it."

On the fortieth day Tatara climbed the tallest mountain in the west and pushed the coal down into its heart. The mountain woke and roared red. Fire ran down its sides like water, and when the smoke cleared the Oni were standing in the warm for the first time in their lives, staring at their own hands.

That mountain is Mount Tatara. The heart she fed it is the Mother Forge of Akagane Hold, and it has not gone out since.

Her hands healed hard, black and red like cooling iron, and could hold hot metal without flinching. She went down to where the mountain bled raw iron, and beat it into a shape.

"And the first thing she made," says Ishiba, "was what?"

"A hammer!" shout the newest children.

"A sword!"

"A pot," says Ishiba, with enormous satisfaction. "Because her people were hungry, and you cannot cook meat in your fist. The second thing was a hammer, to make more pots. The third was a drum, because her hands wanted something to do while the pots boiled. The weapons came much later, and do not let any loud young warrior tell you otherwise."

Some fifty years ago a very small Kenta Akagane put up his hand at this point and asked when Tatara was going to fight something.

"She fought a mountain, boy," said Ishiba. "And she won."

The fire went into the Oni after that. Their grey hides reddened over the generations to the colour of a forge at full heat, and their blood ran hotter than any other people's. An Oni who works or fights for a long time grows hotter, not tired: the heat builds in her like a bellows filling, and the longer the fight, the harder she hits. Their smiths call it the rise. Their enemies have called it other things.

That was the gift the Oni took from Hoshibi: not light, but forge-fire. The fire that makes. Strength to hold the hammer, craft to know where to strike, and the drum, to keep the rhythm while you do it.

And the forge-fire found something in the mountain that the light had left there. Wherever Hoshibi's light falls on stone for long enough, the stone ripens, the way sun ripens a plum, and through the iron that Mount Tatara bled ran thin warm threads of star-gold that hummed when they were struck. The Oni call it hoshigane. The rest of Aurenthal calls it aurum. An Oni smith can feel a seam of it through her boots, and fold it into iron so that the iron holds its heat for a hundred years. Nobody in Tatara's day guessed that one day every wall and tower in Aurenthal would stand on it. They only knew that it made the hammers ring truer.

The Red Reach

West of the Ember Ring the land climbs. First come the iron hills of the borderlands, red-soiled, veined with aurum, and fought over for three hundred years. Then the steep passes. And then, all at once, the Red Reach opens before you like the inside of a furnace.

Mountains smoke on every horizon, and at least one is always grumbling. In the high places the Oni bathe in hot springs in the dead of winter, with snow on their horns, arguing.

Mount Tatara stands over it all, a broad old giant with a white plume at its crown, and on its southern flank sits Akagane Hold. Visitors expect a fortress. What they find is a city that looks as if it was poured. It climbs the mountain in terraces, each one a street of forges breathing smoke. 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.

At the very heart of the mountain, down a stair worn into a gutter by a thousand years of feet, is the Mother Forge: a chamber the size of a small valley with Tatara's fire on its floor. Every war hammer of the Oni is quenched there. Every Oni who dies is sung there.

The Ash-Singers count six great clans.

The Akagane, the Red Iron, hold the mountain and the Mother Forge. They are smiths before they are warriors, and the Iron Father has come from their halls for longer than anyone remembers.

The Kurotetsu, the Black Iron, mine the dark ore under the Kurozaka, the Black Slope. Their mortars throw black iron shells so heavy the ground hums where they land, and when their gunners grow ambitious they pack those shells with something that burns like a small dark sun.

The Hibana, the Sparks, are the drummers of the drum valleys, where wind pours through forests of basalt columns and makes them sing. A Hibana child learns to drum before she can talk. They also make the fireworks for every festival, and it was only a matter of time before somebody put a rocket on a cart and pointed it at an enemy.

The Iwabara, the Stone Thorns, herd shaggy black ash-oxen on the grey grass plains and dig the long tunnels that carry warm water out from the mountains. Give an Iwabara a shovel and a reason and she will bring down a hillside. Give her a sulphur pool and a grudge and she will brew something in a vat that even the Hollow cannot walk through.

The Kumoyama, the Cloud Mountain clan, live in the high cedar forests on the northern ridges, where the mist comes in off the Moonwood. They are timber cutters and builders, and the inventors of a great many saws with a great many teeth.

And the Shiokaze, the Salt Wind, live farthest west of all, on the black cliffs where the Reach drops away into the Pale. They fish the edge of the fog in boats tied to the shore by long iron chains, and they never untie them. They sing to the fog to keep it back. Nobody else is sure this works, and nobody wants to find out.

But an Oni thinks of herself first as band: the people she works with, eats with and fights beside, a forge crew of six or a war band of sixty. "A band is a forge," the saying goes, "and a forge is a family." When two Oni meet on the road the first question is never what clan but whose band.

Every band swears the same oath, and it is very short.

I will not leave you at the gate.

In the old days that meant the gate of a hold under siege. When the band falls back, nobody is left outside when the doors close: not the slow, not the wounded, not the fool who got himself cut off. You go back for them, or you stay out there with them. The Oni have lost battles because of that oath. They have never once considered giving it up.

Other customs visitors learn by getting them wrong. No Oni eats before the youngest child at the table has eaten; a war chief with an empty belly will sit growling while a three year old decides whether he likes turnip. When an Oni child loses her milk tusks they are kept in an iron box no bigger than a walnut, and at thirty, when she comes of age, they are folded into the iron of her first hammer, so that she carries a piece of her own childhood into every fight. Rings on the tusks mark vows: iron for a marriage, copper for a debt owed.

And when an Oni dies, the band laughs. They tell every ridiculous thing the dead one ever did, until the mourners are weeping with laughter and the laughter has turned into the other kind of weeping without anyone being able to say when. Then the dead one's hammer is carried down to the Mother Forge and melted into the great crucible, and the iron goes into the hammers of the next generation. When an Oni says her ancestors fight beside her, she means it in the most practical sense imaginable.

"Grief is only love with nowhere to go," the Iron Father says, whenever a young Oni asks why they laugh. "So we give it somewhere to go."

He has said it at three thousand funerals. And yet on his back, wherever he goes, he carries two hammers that are not his own, and he has never taken them down to the Mother Forge. Nobody in the Reach has the courage to ask him why.

Last of all there is the singing. Every winter, at the longest night, the Ash-Singers gather at the Mother Forge and sing the Long Song: the name of every Oni who has died since Tatara, in order, from memory. Nobody writes it down. The Oni think a name you have only written down is a name you have not bothered to remember. It now takes three days and three nights, and the children fall asleep against their parents and wake hearing the names of people who died nine hundred years before them, and that is the point.

There are, in the Long Song, exactly two hundred and twelve names that are not Oni names.

Ironjaw at the Black Slope

The Long War began in 412 After the Ember, and the Oni will tell you it began over iron and aurum, which is true, and that the Ronin started it, which is a matter of opinion.

The Oni had dug at the iron hills of the borderlands for centuries, casually, as a people who owned more mountains than they could dig. Then a Ronin miner called Jinbei found a deep red seam there, with aurum running through it as thick as a wrist, the richest anyone had ever seen so far from the flame. The eastern seams are thin, and the Ronin had never in their history held so much star-gold in one place. So the humans of the Shirogane Marches came west with their surveyors and their straight roads and their beautiful, maddening sense of order, and built a keep beside it. Then another. Then a wall between the keeps. The Oni pulled the wall down. The Ronin built it again, better. The Oni pulled it down again, and this time people were standing on it.

That, more or less, was the next three hundred years.

It was never simple. There were massacres on both sides. In 689 Ronin engineers broke a dam on purpose above the borderland valley of Tatara, named for the first smith, and nine thousand Oni drowned in a night. The Oni have never forgiven the Drowning of Tatara. Every spring a Ronin Marshal rings a bell on the dam, and every spring the Oni send a watcher to stand on the far bank and hear it, and say nothing.

And one difference made everything worse. An Oni counts her life in centuries as a human counts in decades. A Ronin who killed an Oni's father would die of old age long before the son's grief had begun to cool. The Ronin remembered the war in their books; the Oni remembered it in their bodies, glaring across the border at the great grandchildren of the men who had wounded them. You cannot make peace with a dead man, and the Oni kept having to try.

So the Oni tell their war in heroes, because heroes are what you have left when the reasons wear thin. They honour enemies too, in their way: for an enemy who earned it, the Hibana strike a single drumbeat, and no more. They struck one for Kurogane Sadako, the Lady of the Iron Gate, who held Tetsumon against them for forty three days in 538. But the hero the children love best is Hayame Ironjaw.

In the spring of 563 a Ronin army came over the borderlands on a road built in secret through the winter, and made straight for the Kurozaka. In the deep mines under the Black Slope lived the whole Kurotetsu clan: their old ones, their children, their sick. There was one way out, a long tunnel to the western valleys, and it would take two days to move everyone through it.

The pass above the mine was held by forty Oni, under a Kurotetsu gunner called Hayame who had a loud voice and a bad temper and a habit of singing out of tune. The Ronin had four thousand.

"Two days," Hayame told her band. "Then we can go."

They held the pass for nine.

On the first day the Ronin came up the slope in perfect lines, and Hayame's mortars broke the lines, and the Ronin re-formed them as calmly as if they were folding laundry. On the third day a spear broke Hayame's jaw in two places, and the band's smith wired it shut with iron from his own hammer, and she went on singing through her teeth, more out of tune than ever. On the fifth day word came down the tunnel that the clan was through, and Hayame could have gone. She stayed, because nine of her band were too badly hurt to walk the tunnel, and she would not leave them at the gate.

On the ninth day there were six Oni left, and no shells.

The Ronin commander rode up the slope alone, a grey-haired human on a tired horse, and took off a plain helm among the dead. Hayame never learned the commander's name.

"You may go," the commander said. "Take your wounded. Take your hammers. The road west is open."

Hayame, who could not open her mouth, said through her iron, "Why?"

"Because I would like my soldiers to see that it can be done."

Nobody in the Reach agrees on what that meant. Hayame walked down the western road with her six and her wounded, and the Ronin parted for them, and not one lowered a spear. When her jaw healed she made a drum song about it, the Song of the Open Road, and the Hibana still play it at every great feast. Nobody can decide whether it is a victory song or a lament. For four hundred years someone has stood up drunk at every feast and declared it one or the other, and someone else has thrown a cup. It ends, always, on a single drumbeat.

There is a rule among the Oni that you do not tell a war story without telling the other kind too. So when the children have finished cheering for Ironjaw, Ishiba turns her blind eyes toward the fire and tells them about the Wrong Fire. The Iron Father does not need to hear it. He was there.

The Wrong Fire

In the winter of 716 Gorō Akagane was eighteen, which for an Oni is barely out of the nursery. He had two whole horns and a hammer given early, because his father was the Iron Father and could not bear to wait.

Daitetsu Akagane had been Iron Father for sixty years: a huge, slow Oni with a beard like a burnt hedge, who forged hammers the way other people pray. He had been Iron Father on the night of the Drowning, and he was tired of the war in the way only the very strong get tired, somewhere deep, where rest does not reach.

Gorō was not tired of anything. He had decided, privately, that the Song of the Open Road was a victory song, and that he would like one of his own.

That winter the scouts came back from Asagiri, a small Ronin keep in a fold of the iron hills, with a town tucked inside its outer wall and long stone granaries along the river. For three nights they had lain in the snow above it and watched wagons rolling in from the east, torches moving at all hours, the granaries filling, figures crowding in and out through the night.

"They are stocking a spring campaign," the scout leader told the war council. "Rice and soldiers. If they march in spring with all that behind them, they will be at the passes by midsummer."

Daitetsu asked careful questions. Then he did what any war chief in the Reach would have done, and what he would spend his life wishing he had not.

"We burn the stores," he said. "Not the town. The stores. No food, no campaign."

They went down in the fog two nights later, two hundred strong, the Hibana drums muffled in felt. Gorō went with the torch bearers. He remembers the fog freezing on his horns, and his heart going so hard he was sure the sentries would hear it.

There were no sentries. Nobody wondered about that until afterwards.

The torch bearers went along the granaries in a line, and the roofs went up all at once with a sound like a huge breath let out. Gorō was at the fourth building, and he was grinning, and composing the song in his head.

Then the screaming started, and it was not the screaming of soldiers.

The garrison of Asagiri had heard rumours of an Oni raid that winter. They had ordered the people of the outlying farms to come into town for safety, and the safest buildings in Asagiri were the granaries, with their thick stone walls and heavy doors. The wagons had been families. The torches had been parents carrying children in from the snow. The figures in the night had been grandmothers and farmers and their animals, settling down to sleep in the warm among the rice.

The garrison itself was up in the keep's tower. It arrived in time to see the roofs fall in.

Gorō tells this part flatly. He dropped his torch. He put his shoulder to the door of the fourth granary, and it had been barred from inside against the Oni, so he broke it. He came out of the black smoke with two children under one arm and an old man over his shoulder, and went in again. The third time, the roof was coming down, and a small girl caught hold of his right horn with both hands as he lifted her, and would not let go, and he came out of the fire like that, with her hanging off his head, both of them burning a little at the edges.

When he set her down in the snow he had to unfold her fingers one at a time. She was perhaps five. She looked at him with an expression he has never been able to describe and never forgotten.

By then the Ronin garrison stood on one side of the square with spears down, and the Oni on the other with hammers up, and between them sat the people who had got out, in the snow. For a moment nobody moved.

Then Gorō picked the girl up again and walked out into the open ground. Spears came round to follow him. He walked right up to the Ronin line and held the child out, and a Ronin officer with a soot-streaked face lowered his spear and took her. The two of them looked at each other over her head without a word. Then Gorō walked back to his own side, and nobody threw anything at him, and Daitetsu quietly gave the order to withdraw.

Two hundred and twelve people died in the granaries of Asagiri. The Ronin have never named that night in Oni hearing; they speak only of a keep and a night. The Oni call it the Wrong Fire. It is the only thing in the history of the Reach that is never sung as anything at all.

Daitetsu did not speak for nine days. On the tenth he did something no Iron Father had ever done. He sent an envoy under a truce flag to the keep, to ask for the names of the dead. The envoy waited at the gate for a week. On the eighth morning a Ronin clerk came out, put a folded paper in the envoy's hands, and went back in without a word or a bow.

Daitetsu took the paper to Ishiba, who was young then, and newly an Ash-Singer, and could still see, and asked her to learn it. She did. Every winter since, in the middle of the Long Song, between the Oni who died in the autumn of 716 and those who died in the spring of 717, the Ash-Singers stop, and sing two hundred and twelve Ronin names in order, from memory. The children of Asagiri. Their parents. An old man who kept bees. A farmer called Hiro who had brought his ox.

The Ronin do not know. The Oni have never told them. It has never seemed the kind of thing you could say out loud, and so for two hundred and sixty eight years it has been sung into the dark of the Mother Forge, where only the Oni and the fire can hear it.

Gorō fought five more years and made no more songs. He learned that the Ronin bleed red, hold a line when any sane people would run, and fight hardest for whatever is behind them. He came to respect them the way you respect a mountain that has thrown you off more than once. He called them tin-cans, and would for the next two and a half centuries. Among the Oni, a rude name is a kind of respect.

The war did not end in a great battle. It ran down, like a forge nobody is feeding, and something had gone out of the Iron Father after the Drowning and Asagiri that never came back. In 721 the Truce of the Broken Bridge set the border on the Kurokawa, the Black River, and left the mines between as a grave that neither people would dig.

Gorō was there, a young smith of twenty three with both horns still whole. The Ronin who were there remember him laughing, because the truce scribe's ink had frozen and he offered to warm it in his hands. There was a thin pale scar low on his right horn, where a five year old Ronin girl had held on.

The Famine of Ash

In the spring of 734, Mount Hiwatari blew its top off.

Hiwatari was a sharp young peak in the north of the Reach that had always smoked politely. On the morning it burst, the floor of Akagane Hold jumped, and every drum in the drum valleys rang by itself.

Then the sky went dark from the north, and stayed dark for six years.

The ash fell for a month. When it stopped, the sun hung behind the haze like a coin seen through dirty water. Summer came, and it snowed: grey snow, gritty, tasting of sulphur. Nothing grew. The ash-oxen died in their thousands with their lungs full of grit, and the Iwabara walked among them weeping.

By the first winter every clan in the Reach had come in to Akagane Hold. You cannot eat warmth, and the storehouses had been meant for one clan through one bad winter, not six clans through who knew how many.

Daitetsu was a hundred and eighty by then, and the Wrong Fire had turned in him into something hard and quiet. He ran the rationing himself, ruthlessly and fairly, and when the clan chiefs asked whether to send for help, he refused.

"Send to whom? The tin-cans, thirteen years from the truce, across a river full of our dead? When they say no, we will have shown them our throats for nothing."

A Kitsune trader did come over the northern ridges, with a very carefully arranged smile, to offer grain on credit. Daitetsu read the terms, which ran to eleven pages, laughed for the first time in a year, and sent the fox home without a signature.

So the Oni endured, which they are very good at, and which is very nearly the same thing as being stubborn.

Before midwinter the ash cough came to the Hall of Small Hands, the children's healing house on the third terrace (the Cradle House, as the pandas call it): dry and endless, taking the smallest first. You could hear it all down the terrace at night.

Sumi Kurotetsu, the master smith who had taught Gorō everything he knew of the forge, went down to the Mother Forge one night with the hammer she had carried for two hundred years. She melted it in the great crucible and came back up the stair with eleven cooking pots.

"The first thing was a pot," she said, when Gorō stared. "I am only going back to the beginning."

Gorō was thirty six, the youngest war band captain in the Reach, and quieter than the boy who had gone down to Asagiri. He had lost a wife and a baby to fever before the ash came, and did not speak of it. Without anyone deciding it, the Hold had begun to look to him. He carried the dead down the stair, and told the coughing children stories, badly, and they laughed at how badly, which helped.

Late in that winter the watch on the Ladder of Clouds, the high pass that climbs south through the Ash Teeth toward the Jade Groves, sent a runner down the mountain, shouting something nobody understood at first.

"Lanterns. Green lanterns. On the Ladder. Coming over the snow."

Gorō went up to the border stones at the head of the pass and looked south down its long white throat and saw a line of lights strung out across the snow for a mile, soft and green as new leaves. Under them moved broad black and white shapes, bent under loads, hauling sledges, leading ponies piled with sacks. Pandas. Hundreds of them. They had come over the Ash Teeth in midwinter, where nobody went in midwinter, and they were singing as they walked.

When Gorō brought the news down, Daitetsu's face did not change.

"We cannot pay them. And what we cannot pay for, we do not take. Go up and thank them, with courtesy, and turn them back."

Gorō stood there a long moment. Then he went.

He met the caravan at the border stones, with his brass-bound hammer on his shoulder. The leading panda was the biggest creature Gorō had ever seen who was not an Oni: a monk in a quilted robe white with frost, with a staff in one paw and a great brass bell clanking on a cord around his neck. He looked up at Gorō with small cheerful eyes and bowed.

"Brother Bao, of the Thousand Roots. We heard you were having a bad winter."

"Who told you?"

"The roots." He said it as if reporting the weather. "Everything that grows is connected, a little. When your grass died, our bamboo felt it. Sister Mei has been crying about you since the spring, and we finally decided we had better come and see."

Gorō looked past him at the young pandas at the back, so tired they were leaning on each other as they walked.

"My father says the Oni do not take what they cannot pay for," Gorō said. "So name the price."

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

Gorō stood in the road a while. He was thinking, he said afterwards, about Tatara and the panda with the leaf, and how she had almost taken it. And he was thinking about his father's face after Asagiri: the face of someone who no longer believed he deserved anything good.

Then he stepped to the side of the road.

"Come down," he said. "Come and get warm. I will carry something."

He took the heaviest sledge from two young pandas, who fell asleep on top of the load almost at once, and he hauled it down to the Hold himself, with Brother Bao beside him singing a Shrine walking song so far out of tune that Gorō, despite everything, began to laugh.

The pandas brought rice and beans, lotus root and barley seed, and herbs for the ash cough. Some of the rice sacks bore a small neat mark on the stitching that was not a Shrine sign and that nobody in the Reach could read. When Ishiba asked, Brother Bao only smiled and said a great many hands had helped to fill the carts. Ishiba knew a deliberate silence when she heard one.

That night Gorō went to his father, braced for rage. Daitetsu was sitting alone with no fire lit, and when Gorō came close he saw how thin the old Oni had become under the great beard and heavy robes. Thinner than anyone in the Hold. For months the Iron Father had been eating half his ration and carrying the other half down to the Hall of Small Hands himself, at night, and leaving it for the healers without a word.

"You were starving yourself."

"I was eating after the youngest child," said Daitetsu. "That is the law."

"That is not what the law means."

His father looked at the cold hearth for a long while.

"After Asagiri," he said, very quietly, "I did not think we were owed kindness. Not from anyone. Not ever again."

Gorō sat down beside him on the floor.

"It is not owed," he said. "That is why it is kindness."

Daitetsu died before the spring. He died well fed, in the end, because Gorō sat with him and fed him Shrine rice spoon by spoon, and the old Iron Father ate it, and cried, and ate. When the band sat round to tell the ridiculous stories, there turned out to be many more of them than anyone had expected.

The pandas came every winter after that until the sky cleared, and planted tall carved lantern poles up the Ladder to mark the road through the snow. Their druids stayed in the Hold to tend the sick, and the youngest of them, a small serious panda called Mei Tsukuyomi who was not yet anybody's Keeper of anything, went straight to the Hall of Small Hands and stayed there. She planted a lantern root in its rafters, and it grew along the beams and hung the ceiling with soft green lights that did not flicker, and under them the children's breathing eased, and the coughing slowed, and stopped. She did not save them all. She saved more than anyone had a right to expect. Gorō called her Little Lantern. He still does.

Those lights still burn in the Hall of Small Hands, two hundred and fifty years later. Every Oni child born in Akagane Hold since the Famine has been born under them.

Not every crossing was kind. One winter an avalanche came down on the caravan in the high bowl of the Ash Teeth that the pandas call the Kettle, and thirty eight pandas died under it. In the spring the Oni climbed up and built a cairn there, and laid on it thirty eight war hammers, their own, unmelted. It is the only place in Aurenthal where Oni hammers are left out in the weather, and every Oni who passes it takes off her helm.

Sumi Kurotetsu did not live to see the sky clear. There was no hammer to melt for her, so the band carried one of her eleven pots down to the Mother Forge instead. The smiths still say, with pride, that every Oni hammer made since has a little soup pot in it.

In the spring of 740 the sun came up red and enormous through the last of the haze, and the whole Hold stood on the terraces to look at it, and nobody spoke.

That summer three hundred Oni went south over the Ladder of Clouds without their weapons, hauling on an iron sledge a bell that every clan had given iron for, and laid a feast for the Shrine on a single table that ran along one of the great roots of Grandmother Kusu, the world tree of the Thousand Roots. They kept it laid for eleven days. That was the first Long Table, and both peoples have kept the festival every year since. On the ninth night, very drunk on plum wine, Gorō challenged Brother Bao to a wrestling match on the root, and Brother Bao accepted with the greatest courtesy and threw him so hard into the cook fires that the tip of his left horn snapped clean off. Gorō lay on his back among the cinders, blood running into his eyes, staring at the stars, and laughed until he could not breathe.

He still claims he let Bao win. Brother Bao, while he lived, used to reply that he had let Gorō keep the other horn.

On the last night, at the head of the Long Table, the two peoples swore the words that every Oni and every panda still knows.

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 Oni hung their bell in Grandmother Kusu's crown, and the Iron Bell hangs there today. When they went home, Brother Bao took off his own brass bell, which had cracked in the cold of a crossing and would not ring true, and gave it to Gorō. Gorō drew it out into a ring at the Mother Forge and put it on his left tusk, where it still is. A brass ring on a tusk had never meant anything in the Reach. Now it means one thing only, and the Oni say it in fewer words.

When the Root calls, the Iron comes.

That is Root and Iron. Nobody signed anything. There are no clauses. It is simply a fact, like the heat of the mountain: if the Shrine is ever in need, any Oni anywhere will drop what she is holding and come. The pandas have never once asked. That, the Oni say, is exactly why the vow is so strong.

The Iron Father

The clans chose Gorō as Iron Father at the Mother Forge in the autumn of 740, with the first harvest in six years stacked in the streets outside. A few voices suggested that forty two was rather young. The Hibana had decided the matter in advance, and drummed so loudly that the debate could not be heard.

The vow of the Iron Father has one line, and it is Tatara's answer to the fire.

I will make whatever my people need.

Kneeling on the hot stone with the brass ring new on his tusk and his broken horn still tender, Gorō added to it, which no Iron Father had done before.

"And I will make every hammer myself. Every war hammer any Oni carries, from today, I will forge with my own hands. I will put the milk tusks in the iron myself. I will know every name."

It was a ridiculous promise. There were tens of thousands of Oni in the Reach.

"Why?" Ishiba asked him afterwards. She was the only one who would.

"Because my father ordered a fire," said Gorō, "and two hundred and twelve people died, and he did not know a single one of their names until he asked for them. I would like to know the name of everyone who carries what I make. Before, not after."

He has kept that vow for two hundred and forty four years, and more than forty thousand hammers. Every Oni who has come of age since has climbed to his forge with a little iron box, and watched him fold her milk tusks into the red iron, and heard him say her name aloud as he quenched it. He will stop a grandmother in the street and say, "Seventh hammer of the spring of 812, short haft, you wanted the head heavier than was sensible," and she will go pink to the tips of her horns.

The century after the Famine was the best the Reach had known. The Iwabara filled the mountain with storehouses, which nobody has ever called anything but the Bao stores. The Hibana built the first war taiko, so large it needs four drummers and a cart. The Kumoyama carved the Shrine's lantern poles into tall totems for every hold, in thanks, and when ash hawks came raiding the Bao stores the Hibana fitted those totems with aurum barrels and taught them to throw fire at the sky. They were the first Flak Totems. And the smiths learned to make a small anvil that a crew could carry to a broken wall and mend it in an hour.

Gorō married again in 790: Hotaru, a Hibana drummer, loud and sharp and the only Oni in the Reach who could make him blush. They had two sons. Kōtetsu, born in 812, was a smith to his bones, broad and patient and slow to speak, who could listen to a bar of iron cooling and tell you what was wrong with it. Ibuki, born in 829, was quick and funny and restless, a drummer like his mother, who could not sit through a meal without tapping a rhythm on the table.

"One for the forge and one for the drum," Hotaru used to say. "We made a whole Oni between us. It just came out in two pieces."

She died in 902, of a sickness in the chest that even the Shrine druids could not mend, laughing at something Gorō had said. He has never told anyone what it was. He told the stories at her funeral himself, for three hours, and then sat all night at the Mother Forge with her hammer.

The Fox at the Table

In 752 word came to the Reach that Madam Kuzunoha of the Kitsune had sworn a treaty of mutual defence with the Ronin: the Silver Oath.

The Reach did not take it well. Thirty one years after the truce, the news that the cleverest people in Aurenthal had bound themselves to the Oni's oldest enemy seemed to have only one meaning. The war chiefs shouted for two days, and someone suggested, quite seriously, marching on Silverbough.

Gorō let them shout. Then he sent a single letter north, which said, in its entirety: What is it for?

He did not expect an answer. He got a guest.

She came in the spring of 753, alone, on foot, with a parasol, although it was not raining. The guards at the Hold gate did not see her arrive. They simply turned round and found her behind them, admiring the view.

She was small and silver and very still, and her tails moved behind her in a slow way the Oni found hard to look at. She sat down at Gorō's table and drank a cup of the Reach's roughest spirit without blinking, and accepted another.

"You asked what it is for," she said. "Almost nobody asks."

"Against us."

Kuzunoha smiled, a beautiful smile that told them absolutely nothing.

"Darling, if I wanted to be defended against the Oni, I would simply stay out of your mountains. You have never once come looking for me. No. The Oath does not point west."

"Then where?"

She turned her cup slowly on the table, and for a moment looked not at Gorō but past him, out of the forge door, toward the far west where the Reach ran out and the fog began.

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

"Which dark?"

"If I told you that, you would go out and try to hit it. And it is much too far away to hit. Shall we play dice?"

They played dice. She won every game but one, and Gorō is certain she let him win that one and cheated in all the others, and he has never worked out how. He loved it. 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.

"That fox knew the name of the thing behind the door," he told Ishiba, long afterwards, when the gates had opened. "She knew it at my table, more than two hundred years ago. I would bet my good horn on it."

"Then why do you still play dice with her?"

"Because one day she will slip, and say it. And I want to be across the table when she does."

In the Quiet Century the Ember Ring grew into a great city, and an Oni quarter grew up on its western side around a street of forges that the Oni called, inevitably, Little Akagane. Oni fireworks went up at every festival, and the Kitsune complained about the noise, and the Hibana made them louder.

Gorō went to the Ring every autumn to sell the year's iron and aurum and haggle loudly with Ronin quartermasters, which he privately thought the best part of his year. The aurum fetched three times the price of the iron, and the Ronin always paid it, and always wrote down exactly how much it hurt.

Kōtetsu became his father's only apprentice, and in 931 had a son, Kenta, who screamed from the hour of his birth as though personally insulted by it. Ibuki married the best of the Hibana drummers, a tall, deep-voiced Oni called Benika, who could keep a beat on the war taiko for a day and a night without stopping and was known across the Reach as Benika Thunderhand. They had no children. "We have a hundred," Benika would say, waving at the young drummers who followed her about. "They just keep coming to the house."

In 970 an old Kurotetsu miner, dying, asked to lie with his clan's dead in the grave mines along the Kurokawa, and Gorō carried him down there on a litter with the band. The young heir of Tetsumon, Kurogane Masahide, came to stop them with forty riders. A young Ronin captain got there first. She waded the ford alone and unarmed to see what the Oni were about, and then stood in the middle of the road facing her own side, and kept it open until the last song was sung. Gorō thanked her in the only way he knew.

"Try not to cut yourself, tin-can."

"Try to aim," said Shirogane Aoi.

He laughed all the way home.

Ishiba's sight went in 960, and she went on singing to the fire anyway. And the Iron Father grew old: not weak, for the Oni do not weaken with age, only slow and grow harder to move. His beard went white, and his hands turned as black and red as Tatara's must have been. He forged and haggled and diced with a fox and drank plum wine with pandas, and for a long while it seemed the world had settled into a shape he could live with.

The Night of Four Gates

In the autumn of 981 Gorō was a day out from the Ember Ring on the western road, bringing the year's iron and aurum to market with sixty of his band. His sons had gone ahead with Benika and thirty Hibana drummers, who had been asked to play at the festival. Kenta had been left at home, sulking magnificently over a fight he had picked with a Kumoyama timber cutter, and lost.

They camped on the last ridge of the borderlands, where the glow of Hoshibi lies on the eastern sky like a second sunset. Gorō sat up late by the fire, and so he saw it: for the length of a breath the glow went pale. Not dim, but pale, the way a face goes pale. Every campfire on the ridge guttered at the same instant, as if something enormous had breathed in.

He left the carts where they stood. The band ran the rest of the road in the dark, and came in through the western streets a little after midnight, and found Little Akagane at war.

Benika told him afterwards how it had begun. First a bell: not a temple bell, but a clean, flat chime of three rising notes, out of the air itself, and after it a voice, calm and clear and very slightly bored, from everywhere at once.

Thank you for your patience. Service will resume shortly.

Then, out past the last forges, where the old pilgrim gate of the Oni quarter, the Ashfall Gate, stood in the north western corner of the city, the air had torn. It was like watching cloth tear. The night opened in a ragged upright wound taller than the walls, and behind it was a darkness flatter and colder than any night, pricked with small square lights in rows, like the windows of a city very far away. Out of it the Hollow came walking.

They did not charge. That was the worst of it. They walked, in hundreds, in grey coats and grey hats, with cases in their hands and their heads down, as though late for something. When an Oni stood in their way they struck her down like a branch, and walked on toward Hoshibi. Behind the grey coats came Hollow in heavy plate that hammers rang off, and Hollow that flickered and buzzed and were only half there. Above them flew crows made of smoke and wire, and the lanterns went out where they passed.

The Oni had been at peace for two hundred and sixty years, and were at war again in a heartbeat. Benika Thunderhand threw away her cup and was at the war taiko before anyone else had moved, and the old summoning rhythm, to me, to me, to me, came down over the quarter like blows. All through Little Akagane, Oni came out of the forges and taverns with hammers in their fists, and Kōtetsu took the arch of the gate, and held it.

When Gorō came up the gate road with sixty fresh hammers behind him, his elder son looked round once and nodded, as if his father had come in a little late for supper. "Took your time," said Ibuki, over the drum.

They held the road together through the small hours, against Hollow without fear or hurry or end. And the Oni felt the rise, the one thing the Hollow had not counted on: the hammers of Little Akagane fell harder as the night wore on, not softer.

Then a young panda came running down the ring road from the south with her robe torn and blood over one eye, and caught Gorō by the arm.

"Children," she managed. "The school on the south road. The Hollow came through behind it. Sister Mei is holding it alone. Please."

When the Root calls, the Iron comes.

Gorō looked at the grey tide still walking out of the torn air. He looked at his sons.

"Kōtetsu. Ibuki. Hold the arch. I will take forty and come back."

"Go," said Kōtetsu, without looking round, swinging his hammer in the slow even rhythm he used at the anvil. "We have it."

"Go on, old man," said Ibuki, grinning over the drum. "And bring back something to eat."

That is the last thing either of his sons ever said to him.

Gorō took forty Oni south at a run. He found the little Shrine school among the lotus pools ringed with roots as thick as cedar trunks, burst up through the paving and wound around the building like a fist, and the Hollow tearing at them a splinter at a time. In the doorway stood Sister Mei, old now and small, her paws on the frame and her eyes shut, holding every root at once. She opened her eyes at the sound of his band's drums, and smiled the same smile she had smiled in the Hall of Small Hands nearly two hundred and fifty years before.

"Gorō. You came."

"Of course I came, Little Lantern," he said, and put the first Hollow through a wall.

They brought out sixty one children. Gorō carried four himself, one under each arm and two on his shoulders, holding on to his horns. On the ring road back they found the way blocked by Ronin: a shield line falling back step by step from the Ronin gate, steady as a wall, and in front of it, fighting with a single blade as if she had all night, the captain from the grave mines, silver-haired now, with a crescent crest on her helm.

The two lines met on the ring road with Hollow pressing on both sides, and for one terrible moment it was Asagiri again: two lines facing each other, weapons up, and children between them.

Aoi looked at Gorō, at the four children hanging off his horns, at the sixty behind him. She said one word, crisply.

"Left."

She stepped right. Gorō, without thinking, stepped left. The Ronin line opened like a door, the Oni and the children of the Shrine went through, and it closed behind them, and an Oni and a Ronin ended up back to back in the middle of the road with Hollow on every side.

"I know where left is, tin-can," Gorō growled over his shoulder.

"Good," said Aoi, and took the head off a Hollow that had come too close to him. "Then stay there."

They held the ring road together until first light. Somewhere in the night the Hollow in front of them began walking calmly in circles, and someone saw a faint silver flicker of foxfire running along the paving, as if a fox somewhere had told the road a lie and the road had believed it. Toward dawn Gorō rolled a cart of festival rockets into the thick of them and lit it, and when the smoke cleared the ring road was empty. The Hibana have built carts for that purpose ever since, and the Rocket Carts of the Ashfall Gate are their grandchildren.

At dawn the gates did not close, but they quietened, and the four peoples stood in the wreck of their city and counted.

Gorō went back to the Ashfall Gate alone. The arch was standing, the gate road heaped with broken Hollow, and behind it the people of Little Akagane were alive.

His sons lay on the steps of the arch, side by side, as if they had sat down to rest, with their hammers beside them. He had made those hammers. Kōtetsu's had a short thick haft and a broad flat head, for a smith who liked to feel the iron; Ibuki's was light and long, with a drummer's grip worn smooth. He had folded their milk tusks into them with his own hands, in 842 and in 859, and said their names aloud as he quenched them.

Benika sat beside them, her hands bleeding through their wrappings. She had drummed the whole night, until there were no drums left. She did not look up when he sat down.

"They held the arch," she said.

"I know."

"Ibuki made a joke. Right at the end. A terrible one. I will tell you sometime."

"Tell me now."

So she did, and it was terrible, and the two of them sat on the steps of the Oni gate in the grey dawn and laughed and laughed, until the laughter turned into the other thing, and neither could say when.

They swore the Ember Accord that morning on the steps around Hoshibi, the four leaders, filthy and bloodied and barely on speaking terms. Others have written how it went: that the Unbent Blade said each people should hold one gate, and the Ninth Tail chose the words. The Oni remember Gorō's part, because the Hibana drummed it home that week.

He had come straight from the arch with his sons' hammers on his back, and he has not taken them off since. The Ninth Tail, grey with weariness and frost in her hair, looked him up and down as he came.

"Darling," said Kuzunoha. "That last explosion was almost subtle."

"Almost?" he roared, and the Oni say it was the first time that morning that anyone at the flame had laughed.

"I will hold my gate," said the Iron Father, "until it closes. Or until I do."

Then, because the Oni do not leave a promise unhammered, he looked at the other three in turn: at the Unbent Blade, who had opened her line for him; at the Ninth Tail, who had held her corner alone and asked nobody for help; at the Keeper of the Root, who had once sat up all night in the Hall of Small Hands.

"And one rule. Write it how you like. No gate is left alone. When one gate is breaking, the other three come. Not one of you holds a gate by yourself. Not even the fox."

Kuzunoha laughed, the Oni say, and for once it sounded as though she meant it.

The Thousandth Night

Three years on, the Oni are still at their gate.

Little Akagane is a war camp with forges in it now. The bands come down from the Reach in turns, a season at the gate and a season at home, and the western passes are never empty. The Kumoyama have walled the gate road in timber, and the Kurotetsu have dragged their great black mortars down from the Black Slope and set them in a crescent round the arch. Flak Totems stand above them to bring down the smoke crows, and Rocket Carts wait on rails between the forges, and every one of them is built on a footing of aurum and burns it as it fights. The Hibana have built a new drum, a war taiko so loud that its beat sends lightning crawling along the iron of every tower near it. They call it the Raiden Drum. Benika will not say who it is named for, and nobody needs to ask. Every dusk she climbs onto the platform above the arch and plays the summoning beat, and every Oni in the quarter answers.

The Hollow still come, in waves, walking their patient routes toward Hoshibi. Some bring things that have no business existing: an engine of bone as tall as a keep, a woman under a red umbrella who walks through hammer blows as if they were rain. And between the waves comes the polite voice.

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

"So is a spark," Gorō said, the first time he heard it. "Ever been burnt by one?"

The Accord holds. But it is a thousand nights old, and the Oni can feel it fraying the way you feel a rope going in your hands. They drink with the Ronin now, and brawl with them about once a week, and near the Shrine gate an Oni cook and a retired Ronin pikeman run a noodle stall together and argue about the broth so loudly that both quarters come to listen. The Kitsune send polite advice that turns out, three days later, to have been right, which is infuriating. Shrine druids walk the Oni wards each morning, and the young Oni at the gate have taken to tying a green leaf to their brass rings, which the pandas pretend not to notice and are visibly delighted by.

And there is never enough aurum. A mortar burns a handful a night, a Raiden Drum rather more, and the old seams of the Reach were dug for hammers and festival rockets, not for a war without end. The Common Stores share it between the four gates equally, to the grain, under the eye of a Ronin quartermaster who has never been seen to smile, and every gate believes it holds the hardest corner. The Oni say the shares should follow the hammers. The Kitsune buy more, quietly, from everyone. The Shrine grow Gold Plum Trees and try to give the fruit to the Ashfall Gate, which makes the Oni prouder and more ashamed in equal measure. And this spring an Oni sapper band and a Ronin survey crew came to blows over a new seam found under the Lantern Round, and had to be locked in a storeroom together until they had counted it.

What the Oni want they will tell you at great volume. They want the gates closed. They want to go home, and sit in the hot springs under Mount Tatara arguing about nothing, and raise their children under the lights of the Hall of Small Hands without ever hearing that polite voice.

But how? That is where they have begun to come apart.

The young bands want to go through. Anything that can be reached, they say, can be hit. Their loudest voice is Kenta Akagane, Kōtetsu's son: fifty three, still very nearly a boy by Oni counting, with his father's shoulders and his grandfather's temper and the patience of neither. He was not at the gate on the first night, and he has never forgiven himself, and so he has decided, as the young do, to forgive nobody else either.

"We sit here every night like nails in a board," he shouted at the war council in the spring of 984, "and they come, and we hit them, and they come again. My father died holding an arch. So we can hold it another thousand years? I say we go through and find the thing that talks and break it."

"And who holds the arch while you are gone?" Gorō asked.

"The tin-cans. They love standing still."

The young bands roared with laughter. The old ones were silent. Gorō looked at his grandson a long while. He knew that face. He had worn it at eighteen, walking down to Asagiri in the fog.

Kenta had a second idea, for the nights when going through seemed too far. Under the Kurokawa, in the grave mines the Truce of the Broken Bridge left to the dead, lies the old red seam that started the Long War, still the richest aurum this side of the flame.

"Our towers are starving," he said, "and we are sitting on a meal."

"Our dead are sitting on it," said Gorō. "And theirs."

"Then the dead can lend it to us. They want the gates held as much as anyone."

Nobody laughed at that one, young or old. It was not foolish, and everyone knew it. And everyone knew, too, that the Ronin lord at Tetsumon had been saying the same thing the other way round at every council in Hakuro.

What the Oni fear they say less. They fear the flat cold dark beyond the gates, and the day the fog of the Pale climbs the Shiokaze cliffs and the iron chains do not hold. They fear that Kuzunoha knows more than she says. They fear, a little, that the Ronin will decide they are better off without the Oni.

But deepest of all, where no one is allowed to see, the Oni fear themselves. They are the people who would not put the coal down. They are stubborn and proud and brave, and have never once been able to tell those three apart, and the worst things in the history of the Reach were done by Oni who were certain they were right. If the Accord breaks, they are terrified that they will be the ones who break it, and that all Aurenthal will pay for one Oni's pride.

And they fear for the Iron Father. Gorō Akagane is two hundred and eighty six, the oldest warlord in Aurenthal and the last soul living who fought in the Long War. His hands are still steady. But every Oni knows the arithmetic, and knows too that he has taken no apprentice since the one who died on the steps of the arch.

When Gorō is gone, who will make what the people need?

The Iron Father's Last Idea

On the thousandth night the Hollow came hard, and the Ashfall Gate held, and not one of them reached the ring road. Kenta fought at the arch like three Oni, and was nearly killed twice, and was sent off the line by his grandfather in front of everyone, and went, white with fury.

Afterwards Gorō lit his forge in Little Akagane, as he did every night, and sat before it. He did not forge anything. He took the two hammers down off his back, which he almost never did, and laid them across his knees. There was aurum in both. He had folded it in himself.

Kenta found him there an hour later, with a speech ready. Then he saw what lay on his grandfather's knees, and the speech went out of him.

"You never melted them."

"No."

"You make everyone else do it. Grief is only love with nowhere to go. You say it every time."

"I do."

"Then why?"

The coals ticked.

"Because I left them at the gate," said Gorō at last. "I told them to hold the arch, and I took forty and went south. I was right to go. There were sixty one children on that road, and I would go again. But I said I would come back, and I did not come back in time. An Oni does not leave his band at the gate. So I have been carrying them. I suppose I thought that if I carried them long enough, it would count as going back."

Kenta sat down on the floor beside him, slowly, like someone much older.

There was a small sound at the door. A paper lantern was floating there, round and slightly crumpled, with a little painted face that looked extremely embarrassed. Everyone in the Ember Ring knew Tomo, who guided newcomers at the gates and napped between waves, and had come from nobody knew where.

"Sorry," said Tomo. "I saw the light on. Is it a sad talk? I can go."

"Come in, little one," said Gorō. "It is a sad talk. You may as well hear it."

Tomo drifted over the threshold, and the forge changed.

Kenta saw it first. The coals brightened all at once, as if someone had pumped the bellows, and for a breath they burned not red but gold: a deep, warm, steady gold, the colour of late afternoon, the colour of Hoshibi. The whole fire leaned toward the little lantern the way a flower leans to the sun, or a child toward its mother, and on Gorō's knees the aurum in the two hammers woke and rang, faintly, as if someone had struck them. Then it was red again.

Tomo did not seem to notice, and settled on the edge of the anvil to study the hammers with great seriousness.

"Those are nice. Are you going to make something?"

Gorō stared at the lantern, then at the fire.

"What did you say?"

"I said, are you going to make something," said Tomo patiently. "That is what this room is for, isn't it?"

And Gorō Akagane began to laugh. Not the funeral laugh. The other one: the laugh from the ninth night of the Long Table, flat on his back among the cinders, staring at the stars.

"You are very bright," he said, to no one in particular. "Can you make anything?"

"Grandfather?"

"Tatara asked the fire what it could make, and the fire asked her back, and she said, Whatever my people need." He stood, the hammers in his hands, with a light in his eyes Kenta had never seen there. "Her people. Every Iron Father since has taken that to mean the Oni. And I have sat at this gate a thousand nights making hammers to hit things with, and holding on to these two because I could not bear to put them down."

"I do not..."

"We do not need another hammer, boy. Hammers we have. We need a door." He turned the two hammers over in his hands: the smith's and the drummer's. "Something to shut a gate torn in the air. Or to open one from our side, on the day we are tired of waiting for them to knock." Kenta went very still. "No forge on Aurenthal has ever made one, and I cannot make it alone. The tin-cans know how to build a thing to fit within a hair. The fox knows what is on the other side. The Root can make anything grow into anything." He looked at Tomo. "And something tells me the fire might help, if it is asked politely."

Tomo looked back with great round painted eyes and said nothing at all, which for Tomo was most unusual.

"You are going to melt them," said Kenta, very quietly.

"I am going to give them somewhere to go," said Gorō. "Get your coat."

They crossed the Ember Ring as the night ended, an old Oni and a young one and a small floating lantern, along the empty ring road, past the great warm light of Hoshibi burning steady at the heart of everything, to the far side of the city, where the white walls of the Ronin quarter rose clean against the paling sky.

The gate of the Ronin quarter was barred, and the two sentries before it watched the Iron Father come down the road with an expression of profound alarm.

Gorō knocked. Not loudly. Three times, with the head of his son's hammer.

After a long pause a small door in the gate opened, and Shirogane Aoi stood there, still in her armour from the night watch, helmet under one arm and a cup of tea in her hand, a folded paper in her sleeve, looking as though she had not slept either. She looked at the two hammers in his hands, which she had seen on his back every day for three years and never once anywhere else. She looked at Kenta, and at Tomo, and back at Gorō.

"Iron Father."

"Tin-can," said Gorō. "I have an idea. You are going to hate it."

Aoi considered him for a long moment over the rim of her cup.

Then she stood aside, and held the door open.

"Come in," she said.

Far behind them, in Little Akagane, in a forge nobody was tending, the coals were burning gold.
