Trace Amount

Summary:

Reborn into a world of guilds and dragons, he can copy any weapon ever forged. He could be the strongest mage alive. He'd rather run a guild full of difficult people and keep every one of them breathing.

Notes:

The shape of it: a man reborn as the eldest brother in a house of orphans, who can copy any blade ever forged and pays for each one with a piece of his own life. He could be the strongest mage alive. He'd rather run a guild full of loud, difficult people and keep every one of them breathing. The catch is what that costs him, and how long he can keep the bill hidden. New chapters weekly.

Chapter 1: Trace Amount — Ch1: Beware the Master

Chapter Text

The first thing Lucy Heartfilia understood, when she woke, was that the light was wrong.

It came down through the great tree at the wrong angle, long and gold and low, the light of an evening that had no business arriving, when the last thing she remembered was a black shape filling the whole sky and a roar that had unmade the air in her chest. She remembered Natsu's hand closing over hers. She remembered a small voice she couldn't place, somewhere very far off, saying a word none of them had been able to hear over the dragon. She remembered deciding, in the last clean second of her life, that she was not afraid, and being almost entirely wrong about that.

And now there was this gold light, and the smell of leaf-mould and salt, and somewhere very close a bird going about its small ordinary business as though the world had not ended at all.

She sat up too fast. The roots of the Tenrou tree pressed their pattern into her palms. Around her the others were stirring in the same slow, drugged way: Gray with his arm thrown across his eyes, Erza already on one knee with a hand at a sword that wasn't there, Natsu making a sound that was half a snore and half her name. Wendy. Happy. Carla. Levy somewhere behind, swearing softly, which from Levy meant genuine distress. And Master Makarov, off to one side, curled small and ancient against a root, only just beginning to stir, the seven lost years letting go of him by slow degrees. They were all here. They were all whole. They were lying in a ring under the tree exactly as they had fallen, as if a careful hand had laid each of them down to sleep and then waited.

"Okay," Lucy said, to no one. Her voice came out cracked. "Okay. We're — we're not dead. That's. That's good. That's a good start."

"It is one of the better ones," said a voice, "though you have set the bar very low."

There was a girl standing in the gold light, her bare feet not quite touching the moss.

Lucy did not know her. She was certain of it at once (you would remember a face like this) and yet there the girl stood as if she had always been standing there: perhaps thirteen, barefoot in a frilled, old-fashioned dress, with very long hair the pale gold of early sunlight and eyes far too old for the rest of her, and the late sun went through her at the edges, lit and translucent at once, a stained-glass child. The guild mark on the back of Lucy's hand gave a faint cold tug, a small private signal she had never felt before and did not understand, that seemed to say, only you. Only the ones who carry the mark.

Erza was on her feet between the girl and the rest of them before Lucy had finished blinking, one hand thrown out, the other still reaching for the sword that wasn't there. "Who are you," she said. It was not a question. "Where is this."

"Tenrou. Still." The girl tipped her head, and the gold light slid across the place where her face wasn't quite solid. "And you are welcome, by the way, though I see we are going to skip past that part." A small pause, almost kind, almost not. "Seven years."

The words didn't land. Lucy heard them and set them down somewhere and went on breathing, because there was no shape in her mind they fit into.

"…What?" said Gray. He had taken his arm off his eyes. He was looking at his own hands as if they might have aged without him.

"You have been asleep under this tree for seven years." She said it lightly — seven years, as lightly as it rained while you were out. The whole world had turned over seven times. Lucy had been twenty-two for seven years and had not aged an hour. Somewhere her father was, somewhere everyone she had ever known was, seven years further down the road, and the girl delivered it swinging one translucent foot, watching them take the blow with an interest that was not, Lucy thought, entirely kind.

"Who are you," Erza said again, lower now, and dangerous.

The answer did not come from the girl.

It came from the edge of the ring, in a voice gone strange and thin. "…I know that face."

Makarov had woken. He was sitting up against his root, ancient and rumpled, and he was staring at the translucent child with an expression Lucy had never seen on him, not fear, not quite; something closer to the look of a man who has turned a familiar corner and found the dead standing patiently at the end of it. "I have known it my whole life and never, not once, in the flesh," he said, very quietly. "It hangs at the top of the stairs, in a portrait so old that no one remembers to dust it." He got to his feet, slow, his knees cracking like green wood, and then he did a thing Lucy had never seen Makarov do for any king or council or god in all her years in the guild: he bowed his head. "That is the First Master. That is Mavis Vermillion. The woman who founded this guild — and who gave me my name, the day I was born under its roof."

The silence that followed had a different weight than the one before it.

"The — founder?" Gray's voice cracked. "Gramps, she's been dead for—"

"I never said dead," Makarov murmured, not looking away from her. "Fairy Tail has never been especially good at staying dead."

And the girl (for she was Mavis now; the name settled over her and made her at once smaller and immeasurably larger) accepted all of it with the supreme unconcern of someone who had expected to be recognized eventually and was mostly put out that it had taken so long. "Third," she said to Makarov, with a small regal nod, as one might greet a serviceable old retainer. "You've gotten old. It's dreadful. We'll discuss it later." Then, briskly, to the rest of them, before Natsu could give shape to whatever enormous question was building visibly behind his face: "There is something you need to know before you go home," she said, "and I have had a long time to decide how to say it, so I am going to say it plainly, and you are going to listen."

She drifted closer, and the mark on the back of Lucy's hand went colder, and when she spoke again the brightness had gone out of her voice and left behind something low, and careful, and very old.

"There is a man sitting in the master's chair. He came while you were asleep, and he calls himself yours." A pause; the gold light did not seem to reach her now. "And I have been trying to read him since the day he walked in off the road — I read everyone, it is the one thing I am for — and do you know what I have to show for it, after all this while?" The too-old eyes moved over them, slow, one by one. "Nothing. Not a single page. I do not know what he is."

The words sat in the warm evening air and did not warm.

Lucy heard her own voice come out of her, small and unsteady, before she had decided to use it. "She doesn't know." She was looking at Erza, at Makarov, at anyone. "The First Master just stood there and said she can't — that she doesn't—" and she couldn't make herself finish it, because finishing it out loud meant it was real.

Makarov had not spoken since he named her. He spoke now, and it was not the big brass roar he used on the guild; it was something gone small, and old, and tired. "Seven years." He said it to his own folded hands. "I shut my eyes beside my sleeping children, and some stranger walked in off the road and picked up my guild and held it — seven years — and now the First Master of Fairy Tail is standing over us to tell me the one soul she could never read to the bottom of has had his hands around everything I love since the day I went under." His throat worked, once. "...Tell me the rest of it, First. I would sooner hear all of it standing up."

"And why," said Erza, carefully, respect and steel in equal measure, "should even the First Master fear the man who kept this guild standing while we slept?"

"Because I have watched what he does." Mavis did not raise her voice; if anything it dropped, and that was worse. "That man will lie. He will cheat. He will do whatever a thing asks of him to reach the end he has already settled upon — and he reaches it, every time, without fail. I have watched him decide that he wants a thing, and then simply arrange the world, smiling all the while, until the world lays the thing in his hands and thanks him for carrying the weight of it away."

She drifted a step nearer, and her mouth curled — somewhere between distaste and a kind of baffled contempt. "And then there are the women. He keeps a whole flock of them, every one a beauty, and the moment he turns that tired smile on a girl she goes — silly. Soft in the wits. I have watched grown women, women who ran their own affairs and answered to no one, melt into simpering creatures who fetch his tea and finish his sentences and gaze at him across a room as though he hung the moon and a fair number of the stars besides. One, and then another, and then another — he gathers them in, and they bloom at him, glowing and witless, and not a single one of them appears to notice she has handed over every last part of herself to a man none of them can tell you the first true thing about. A whole house full of swooning fools — and him in the middle of it, smiling."

Something shifted behind the too-old eyes then, and it was not spite, nor anything like it; it was the careful blankness of a person standing at the lip of a very great drop and declining to look down.

"And I founded this guild," she said. "I have read the soul of every creature that ever crossed its threshold — the brave, and the broken, and the ones who came in smiling to do us harm. And his I cannot read at all. That is the part that empties the air out of me. I cannot tell you what a man like that is for — what so careful and so patient and so endlessly victorious a man means to do, in the end, with a houseful of people who would lie down in the road for him and call it joy — only that he has built himself exactly that, soul by soul, on purpose, and folded whatever he intends away behind the kindest face you will ever in your lives be lied to by."

Gray had gone very still, and very white, and for once the frost did not even think about coming up off him. "...Great," he said, flat and cracked, to no one in particular. "So the man who's had the run of our home for seven years didn't just walk in and take it. He made every single soul in it grateful he did — and not one of them can even see it." He shut his mouth like he wished he hadn't opened it.

"First Master—" Erza tried.

"And I cannot decide," Mavis said, low and riding straight over her, and there was something almost petulant in it now, a child genuinely affronted by a puzzle that would not come right, "whether that makes him the safest man in all of Fiore or the very worst thing walking about in it. I have turned it and turned it and it will not land. I do not know if he means you well. And I crossed an entire island to stand over a tree full of sleeping children and say as much, which even you will allow is no small effort for a dead woman." She drew herself up, and whatever brightness she had come in with had burned all the way down now, and left only the bare thing underneath. "Be careful of your master. Be careful of his kindness most of all. And until you understand what he is—" the gold light caught and held in the ancient eyes "—and you will not understand what he is—"

For a moment she did not look like a child at all.

"—be a little afraid of him. He is a very bad, bad man."

For a long moment none of them said anything at all. Somewhere up in the branches the bird had stopped singing; Lucy could not have said when.

"You can't just say that," Natsu got out, finally, hoarse. "You can't — who is he. What did he do."

But the cold thing that had been looking out of the girl's face was already folding itself away (as neatly, Lucy thought, with a chill she did not understand, as the man she'd described must fold himself) and when Mavis spoke again the bright strange child was back in her voice, as though it had never gone. "Go home. He already knows that you are awake; he always knows." She drifted away across the impossible gold evening, toward the sea and the long road and whatever was waiting at the end of it, and she said the last of it quietly, almost to herself, in a tone Lucy could not begin to read. "He has probably saved you a plate."

And then, because Lucy happened to be looking right at her, she saw Mavis's face do one more thing, fast, and almost hidden, and so unlike everything else that she half-doubted it even as she saw it.

It looked, for just a second, like grief.

Then the gold light was empty, and she was gone, and far off across the water a bell began, very faintly, to ring them home.


The Strausses found him in his second winter, in the snow at the edge of a market town: a hollow-eyed silent thing too small to be out alone in that cold, and far too still to be a child.

Whatever family the cold had taken from him before that, he never spoke of and never asked after. He had been some days on his own, and strangely unbothered by it, when a man with a great dark beard and a woman with white-gold hair crouched down in front of him in the snow and looked at him for a long time.

He would remember the woman's face for the rest of two lives. He had been very good, in the other one, at reading faces, and he read hers in a single second and found in it the one thing he had no defense against: not pity — pity he could have refused — but recognition. She looked at the silent old thing sitting behind the child's eyes, and she did not flinch from it, and she did not ask him to be any smaller than he was. She only held out her hand and said, "Well. You'll be ours, then," as if it had been settled somewhere out of his hearing; and he was too tired to argue; and that was how he became a Strauss.

That had been four winters ago. The boy from the snow was six now — taller, quieter, already too useful about the house — and still, under all of it, not a child at all.

It was the stone he carried everywhere in his coat, privately, constantly, knowing the exact weight of it. He had come into this world as any child does, and then, somewhere in the first wordless years, the rest of him had arrived: not gently, but the way a tide comes into a sea-cave, all at once and from below, so that a great deal of him had drowned in it and come back changed. Another life. A long one, that had ended, and then somehow not ended, and then ended again, worse. A war he had walked into as a boy with a head full of light and walked out of as something that was no longer, strictly, a person: small soft hands that already knew, in some grain below memory, how to make a blade out of nothing and put it through a man who deserved it, and several who hadn't. And then a long gray after, longer than the war had been, until at the very end of it he had been so tired that the tiredness had become a kind of faith. He had stopped wanting things. He had finished that life a man with no wants left at all, and mistaken it, at the time, for peace.

And then he had woken small and squalling in a cold Earthland house, and the first thing he felt, before he could stop it, was no.

Because he knew exactly what wanting cost. He had the receipts; he had buried them. He had not wanted this — any of it. So he had spent these years standing carefully at the very edge of his own existence with his arms folded, like a man brought against his will to a party, waiting politely for the thing to be over. Even the light he kept at arm's length (the light in Earthland was younger than any he remembered, falling across the wheat as it falls in the first paintings a person ever makes, before they have learned shadow, generous and certain of its welcome) and he would stand in the door of the Strauss house at the gray edge of morning and watch it come up over the eastern field and feel a thing in his chest that he had decided, after long consideration, not to look at directly.

They named him Shirou.

That was the strange part, the part he turned over sometimes in the dark. He had had the name already (it had come up out of the tide-water with the rest of him, the one syllable of the old life that had survived intact) and when the bearded man had asked the silent boy if he had a name, the boy had said it, the only word he'd spoken in a month, Shirou, and the man had nodded as if it were a perfectly ordinary Fiore name and never questioned it again. So he kept it. It was the only thing he had brought across. He held onto it like the one photograph that survives a fire — not because it was beautiful, but because it was proof.

For four years he was their son as a lodger is a member of the household: present, useful, unfailingly polite, and somewhere else. He chopped the wood. He learned the letters they taught him a year before they expected and then pretended to keep struggling, because a child who learns to read in a fortnight is a child people ask questions about, and he had decided, very early, that he would be no one's question. He let the bearded man (Father, he made himself think the word, like a man practicing a foreign phrase) teach him to fish, and he caught fish, and he ate at their table, and he kept the wall up. The wall was very good. He had built it over the course of a war and refined it over the course of an eternity, and a farming family in a backwater of Earthland was never going to be the thing that brought it down.

He had been so sure of that.

He thought about it, later, for the rest of this life he thought about it, the arrogance of it. He had survived the worst things a world could do to a man, and he had walked into a warm kitchen thinking he understood what he was up against.

The bearded man came closest, in those four years, to finding the seam — and never knew that he had, which was very likely the only reason he came close at all.

He was not a clever man, not by the measure Shirou's first life had set for the word. He was a fisherman. He mended nets, and fixed what broke, and said perhaps thirty words on a generous day and meant every last one of them. And in the gray hour before the village stirred, every single morning, he would set one heavy hand on the boy's shoulder where he lay pretending at sleep, and say, "Coming" (which was not a question) and go out to the water; and every morning, after the first month or so, the boy got up, and pulled his coat on in the dark, and came.

The lake at that hour was a sheet of hammered pewter. Mist stood on it in long low banks; the far shore was a rumor; the only sounds were the drip off the oars and the small private complaints of the boat. The bearded man would row them out past the reed-beds with the slow inevitability of a thing that has done it ten thousand times, and set the boy to the lines, and then simply be there, large and silent and unhurried, a presence like weather.

And the boy was good at it. That was the part that had cost him, the part he had not been able to help. His small hands knew the work a beat before they were shown it: the clean economy of a body that had once been, for a very long time, a tool; the unthinking efficiency of someone for whom a wasted motion had once been the difference between living and not. He hauled and coiled and read the flat water's small tells with a steadiness no child has and no child should, and the first morning he did it the bearded man watched him out of the side of one eye for a long, weighing moment — and said nothing. And the second morning said nothing. And went on, day after gray day, saying nothing at all, in a silence the boy came only slowly to understand was not incurious but kind: the deliberate, mountainous kindness of a man who had decided that whatever this child was, and wherever the rest of him had come from, it was the child's to tell or to keep, and not a thing to be dug after.

It was the not-digging that was dangerous. Shirou could have stood against questions; he had two lifetimes of practice standing against questions. He had no practice at all at being simply, patiently, let be.

And once, only once, in four years, the man came near to saying the thing aloud. They were drifting in the mist with the lines out and the village gone invisible behind them, and the boy had slipped off somewhere behind his own eyes, gone, as he did, away into the gray country of the other life. And the bearded man looked at him across the little boat, around the cold stem of his pipe, and said, not unkindly, "You carry it well. Whatever it is." A long pull of mist between them. "Carried a few of my own. Everyone does, who's lived. The trick of it nobody tells you—" he paused, choosing with the care of a man who has only thirty words a day and cannot afford to waste one "—is that you set it down when you're able. Even a little. Even the once in a while. You'll ruin your back else, holding it all up alone, all your life. I've seen men do it. It doesn't end well for them."

And for one heartbeat, one single heartbeat in four guarded years, the wall went thin as the mist, and something behind the boy's ribs turned over and ached toward the unclever gentle man with a force that frightened him badly. Then the bearded man, who did not know what to do with a silence gone suddenly fragile, spat neatly over the side and said, "Mind the third line. It's fraying," and the moment closed over like water, and neither of them ever spoke of it again.

But the boy had felt it — the wall, for that one heartbeat, simply gone — and understood, sitting in the cold boat with the young sun coming up at last across the pewter, that this man was reaching him without trying to; and that if he stayed in this boat in this gray hour long enough, some morning the wall would simply not be there at all. So he was careful, after that. He came to the boat, because not coming would itself have been a kind of answer, and he was good at the lines, and he held the wall.

He held it, in the end, against the father. Four years, and he never let it fall.

It would take someone much smaller, and far fiercer, and entirely without mercy, to bring it down.

Then the woman with the white-gold hair got round and slow and laughing through a long summer, and on a night in late autumn, with the rain coming sideways off the eastern field and the bearded man pacing a groove in the floor and the midwife shouting cheerful brutal instructions through the wall, the Strauss family had its first child of its own blood.

And Shirou, ten years old, was put in a chair by the fire and told to wait, and given, an hour before dawn, with no ceremony at all, a small heavy furious bundle to hold.

He had not wanted to take her.

He remembered that, too, with shame and with a kind of awe at his own stupidity: that even then, even in that moment, the wall had been up, and his first clear thought when the exhausted woman held out the blanket had been a flat interior no, I can't, don't make me hold that, I will only watch it die. Because that was the lesson. That was the one thing his whole long ruin of a life had taught him for certain — that the things you held, you lost; that to love a small breakable thing was to sign a contract whose only term was grief; that a man who had buried everyone he ever reached for had no business reaching again.

But you cannot say no to a woman who has been in labor for nineteen hours. There is no wall in any world that holds against that. So he took the bundle, stiff-armed, held out at arm's length like something he intended to give back immediately —

— and the baby opened her eyes.

They were enormous. They were the blue-going-gray that newborns are, the unfinished color, and they did not focus on anything, because newborns do not focus on anything, and Shirou knew this, knew it with the same flat certainty as the weight of a wardrobe in his arms, that she could not see him, that there was no one home behind those eyes yet, that this was simply a small mammal doing the small involuntary things small mammals do.

She looked at him anyway.

That was how it felt. That was how it felt and there was no arguing his ten-year-old heart out of it: that the furious red unfinished creature in his arms turned her unfocused unfinished eyes up to the old ruined soul holding her and looked at him, without fear, without judgment, without the faintest idea of all the reasons he had compiled across either life for why he should not be trusted with anything precious — and decided, in the bottomless democracy of the newborn, that he would do.

And the wall came down.

It didn't crack. It didn't crumble by degrees over a tender season as these things are supposed to. It came down all at once and from below, like a tide into a cave, the way the other thing had come, and a great deal of who he had decided to be drowned in it and did not come back. He sat in the chair by the fire with the rain going sideways past the window and the gray dawn coming up over the field, holding a baby who could not see him, and he felt the old tired peace, the peace that was really just the absence of wanting, break open down the middle, and underneath it, raw and terrible and alive, was the one thing he had spent a second childhood and an entire previous existence learning to do without.

He wanted.

He wanted this. He wanted the small furious weight and the unfinished eyes and the warm kitchen and the bearded man weeping unashamedly in the doorway and the years, all the years, every ordinary terrifying year of watching this creature grow into whoever she was going to be. He wanted it so much and so suddenly that it frightened him more than anything had frightened him in a long, long time, because he knew exactly what wanting cost, he had the receipts, he had buried them — and he looked down at the baby and understood, with the clarity of a man reading his own death sentence, that he was going to pay it anyway. That he had already decided. That somewhere out of his own hearing it had been decided, as these things always were, you'll be ours, then, and he was too far gone to argue.

"Her name's Mirajane," the woman said from the bed, watching him with knowing exhausted eyes, having seen, he realized, the whole thing happen on his face. "Mira. What do you think?"

Shirou looked down at his sister.

"I think," he said, and his voice did something it had not done in either life, it shook, "I think I'll keep her."

The woman laughed, soft and wrecked. "You'll keep her," she agreed. "You'll keep all of us, I expect. You've got that look." She closed her eyes. "Stubborn boy. Old soul. I knew it in the snow." And then, drifting, already half into the sleep her body was demanding: "Don't let her get away with anything. She's going to be a terror."

She had no idea. None of them had any idea (not the dying mother, not the weeping father, not the boy in the chair with the tide breaking over him) how completely, how famously, how dangerously right she would turn out to be.

Shirou held his sister until the sun was all the way up.


After that he stopped pretending he could read at a normal speed, mostly because he no longer had the patience to be no one's question, and a man who is teaching a small terror her letters cannot afford to be slow about it himself. He let the wall stay down. It was the hardest thing he had ever done, harder than the war, harder than the long gray service after it, to walk around in the world without it, skinless, every nerve out in the open air, knowing the bill was coming and choosing the warm kitchen anyway, one ordinary day after another.

Elfman came two years after Mira: a fat solemn boy who cried at loud noises and grew, by degrees, into a child who said the word man as other children say please: a small magic spell muttered against the dark. And then Lisanna, last and least and white-haired like her mother, who the family always swore had been born laughing. Shirou had been in the room for that one too, by then unable to imagine standing anywhere else when a Strauss was being added to the world, and he could confirm under oath that it was very nearly true: she had come out furious like all of them, and then, within a minute, while her mother held her and her father wept and her terrible older sister glared down at the wrinkled red intruder with naked six-year-old jealousy, the baby had looked up at the candlelit ceiling and made a sound that no one in that room would ever agree to call anything but a laugh.

Three of them, then. Three small breakable furious miracles.

By the time Mirajane was six she was, precisely as her mother had foretold, a terror, and on the kind of long blue winter evening that Shirou would spend the rest of his days trying to hold onto, she was conducting a war.

"You can't have the crust," she was informing Elfman, with the absolute moral authority of the eldest, standing on the bench so as to better command the table, "because last time you had the crust you cried."

"I didn't cry." Elfman's lower lip, four years old and trembling, suggested otherwise. "Men don't — men don't cry about bread."

"You're not a man, you're a baby, and you cried."

"Mira," Shirou said, from the hearth, not turning around. He had learned long ago that he did not need to turn around; the not-turning was, in fact, the entire weapon. "Whose crust is it?"

A pause, thick with the sound of a six-year-old calculating. "…His," Mira admitted, in the tone of a general signing a treaty she fully intended to violate.

"And what do we do with a thing that is someone else's?"

"Give it back," chorused two voices: Mira's aggrieved, and from the floor by the fire, where she was systematically removing every log from the basket and arranging them by a logic known only to herself, two-year-old Lisanna's, delighted, a half-beat late and entirely without understanding, give it back!, because Lisanna had discovered that week that the surest route to her brother's attention was to agree loudly with whatever the room had most recently said.

Shirou turned around at last. The crust was, by then, very much in Mira's fist. She met his eyes with the flat unrepentant stare of the genuinely guilty, and he looked back at her, and he felt, as he felt forty times a day, as he had felt every day for six years, the great helpless tide of it go through him, the wanting, the keeping, mine, these are mine, I will burn the world flat before I let it take a single one of them — and he kept his face entirely stern, because a man who is raising a terror cannot afford to let her see how completely she has already won.

"Give your brother the crust," he said, "and you can have the heel of the new loaf when it comes out. Which is bigger. Which I will deny saying if you tell anyone."

Mira considered this. Then she flung the crust at Elfman with the air of one making a tremendous sacrifice, climbed down off the bench, came around the table, and (because she was six, and a tyrant, and his) wrapped both arms around his leg and held on, fierce and wordless, three or four times a day, as if to confirm he was still where she had left him.

He put his hand on her white-gold head. Across the room their mother caught his eye over the mending in her lap, and smiled the small knowing smile she had been giving him since the snow, you'll keep all of us, I expect, and their father grumbled something into his beard about discipline that fooled absolutely no one, and the fire moved, and the blue winter dark pressed gently on the windows, and Shirou stood in the middle of his stolen, undeserved, impossible second life with a child clamped to his leg and a loaf coming up golden in the oven and thought, with the clear flat certainty of a man reading a verdict: I would die for this. I would do worse than die. There is nothing I would not spend.

He had to go out to the barn, after, when the children were down. He did that, some nights. The happiness got too big to keep inside a person and he would go and stand in the cold dark with the animals breathing and the frost coming and let it be enormous where no one could see, until he could fold it small enough to carry back indoors.

It was on one of those nights that the world first came to remind him what it was.

He had been in the barn perhaps ten minutes when the cow stopped chewing.

That was all. A small thing. The patient endless sound of a cow working its cud simply stopped, and in the silence Shirou felt the back of his neck go cold in a way that had nothing to do with the frost: an old cold, a learned cold, the cold of a body that had spent the better part of both his lives being told by the dark when the dark was no longer empty. He did not move. He stood very still in the stall with his hand on the cow's warm flank and he listened past his own heartbeat, and out beyond the barn wall, out at the black edge of the eastern field where the young light came up every morning, something large set one foot down in the frozen grass and then waited to see if it had been heard.

Earthland was a beautiful world and a generous one and the light in it was younger than any light he remembered, and it was also (he had always known this, under the warmth, the knowledge sitting in him like a hand's knowledge of cold water before the plunge) a world full of monsters. They came down out of the hills in hard winters. Everyone knew it. The village knew it. It was why the men kept iron by the door and why no one let the children past the fences after dark, and it was the one fact of this life that the old soldier in him had never for one moment forgotten, even while the rest of him taught letters and baked bread and learned how to be loved.

He could feel the old self wanting to wake.

That was the thing no one would ever know, the thing he would not let even his own face know, standing alone in the dark. Some grain below memory, below choice, the part of him that had been forged in a fire and tempered in a war and worn down across an eternity into something that was no longer quite a person stirred at the smell of a hunting thing near his family, and surged — easily, gratefully, the way a hand finds in the black a railing it has held ten thousand times — up toward the surface, toward the old terrible competence: the soldier who had once known a hundred ways to turn a predator inside out before it finished its next step.

He did not know, any longer, what that self could still do. Whether the old craft would even answer if he called it, down here, in this small borrowed body; whether the hands that had once made weapons out of empty air in another life could still manage the trick in this one. He had never tested it. He had never dared. Because he understood, in the place below proof, the one thing that mattered: that the day he reached down into that sleeping dark and called the old self up, it would not lie back down again — and on that day the old life, the whole long gray ruin of it, would finally come looking for the new one. The war was not over. It had only ever been waiting, very patiently, for him to go and wake it.

He had let one wall fall already, for a white-haired infant in a candlelit room, and never once regretted it. This was the other wall, older, and deeper, and far worse — and this one he would not let fall for anything in any world.

So he did not reach.

He put it down, the wanting, the reaching, all of it, with an effort that left him shaking, and he picked up instead the long iron pry-bar that hung by the door, ordinary cold iron that any frightened farmer might hold, and he walked out into the black field alone, a tired man with a piece of metal, and he did the thing he had decided to be instead of the thing he was: he stood between his family and the dark, and he was only that, only a brother with a bar of iron and a great deal of nerve, and when the thing in the field smelled the old killing quiet coming off him anyway (smelled it as animals do, as a man in a dark street two lifetimes from now would feel a cold hand at his throat that no one else could see) it decided, on balance, that this farm was not worth what this farmer was, and it turned, and it went back up into the hills, and it did not come down again that winter.

The children never knew. In the morning there were only tracks in the frost, large and clawed and already softening, and Shirou raked the snow over them before Mira was awake, and made the bread, and said nothing, and the young untroubled light came up over the eastern field exactly as it always did, generous and certain of its welcome, falling across the place where, in the dark, he had stood with all his ruin held down inside him by his own two hands and chosen, one more time, to be a small soft harmless thing.

He stood in the doorway and watched it come up and felt the old knowledge turn over in him like a sleeper — the things you hold, you lose — and he pushed it down, as he always did, and went in.

He had bought himself a little more time. He knew that was all it was. The wall had held tonight, and it would hold tomorrow, and it would go on holding right up until the night, and he could not see it yet, could not have named the shape of it, but he could feel it out there, the same cold certainty as the foot coming down in the frozen grass — the night it would stop being a choice.

But that was still to come. For now there was only this: a man who had decided to keep a family, standing in a doorway in the youngest light in any world, with no idea that a girl named Lucy would one day wake under a tree seven years and a lifetime away, and be warned in the gravest possible terms, by a translucent child holding a very old grudge, to beware of him.

He started the bread.

Behind him, in the warm dark of the house, the terror he had decided to keep made a small sleeping sound, and his whole impossible heart turned over toward it — as it would keep turning, and turning, for everything he had not yet begun to lose.
