Sunlight struck the marble pillars of Veranthos at an angle that turned the stone the color of old bone. Dust motes drifted through the columns where Kael Ashworth had been made to wait, three floors up in the eastern wing of the garrison command, and the only sound was the slow tap of his boot heel against the tiled floor. He had been tapping for the better part of an hour.
A magistrate's summons to Lord Commander Theron Marrick was not the sort of invitation one refused. The seal on the parchment had been stamped in black wax, twice, the second impression pressed hard enough to crack the rim of the first. Kael had turned it over in his hands at the inn the night before, tracing the broken crown that marked the royal garrison, and felt the old, familiar weight settle across his shoulders like a hand.
He had worn his magistrate's coat into the hall. It was plain, dark wool, sewn for travel rather than ceremony, with a single silver clasp at the collar marking his office. Beneath it he still carried the soldier's stance, feet planted, shoulders squared, the posture of a man who had learned to stand at attention before he had learned to read a contract. That was what eight years in Crown service left behind. The orders faded. The posture never did.
The door at the end of the corridor was oak, banded in iron, and it opened without anyone having knocked. Kael stopped tapping his heel. He straightened his cuffs. He had not realized, until that moment, how much he had been dreading this.
The room beyond was smaller than he had expected. Maps covered every wall, pinned at the edges with iron nails and weighted at the corners with iron studs. A long table ran down the center, scarred with old knife marks, and at its head stood Lord Commander Theron Marrick, hands clasped behind his back, the silver gorget at his throat catching the pale light from a high window.
Marrick was a lean man, neither tall nor short, with a long face that gave nothing away. His eyes were the color of river water and just as still. He wore the full dress of his rank, the dark blue cloak of the royal garrison falling from his shoulders in heavy folds, and the sword at his hip had been polished until it threw back the window light like a sliver of mirror.
"Knight-Commander Ashworth," Marrick said. The words came out level and clipped, as if each one had been measured against a ruler before being allowed to leave his mouth. "You received my seal."
"I did, my lord." Kael crossed the threshold and bowed, one fist pressed lightly to his chest. The bow he gave was the soldier's bow, quick and correct, not the deeper court bow a magistrate might have offered. He was not sure whether Marrick would notice. He suspected Marrick noticed everything.
"You may have wondered why a travelling magistrate has been called to the garrison command in the capital, rather than to one of the border posts where you customarily conduct your work." Marrick did not move from his place at the head of the table. He did not invite Kael to sit. "I am going to tell you."
Kael inclined his head. The dust in the room tasted faintly of chalk and ink, the sharp mineral tang of old paper, and beneath it the cold iron smell of the nails holding the maps in place. Somewhere below the window, three floors down, a horse snorted in the garrison yard, and a sergeant's voice barked a number that Kael did not catch.
"Six weeks ago," Marrick began, "a farmer in the village of Greymoor, seventeen leagues east of here, brought a sack of grain to the Crown inspector at Hollowmere. The grain was black. Not burnt, not mold, not rotted. Black, as if every kernel had been turned to soot in the husk. The inspector sent the sack on to me."
He paused. He let the silence stretch until Kael could hear the tap of his own pulse in his ears.
"Since then, three more villages have reported the same. Blackened barley. Blackened oats. Blackened wheat, in one field, where the heads of the stalks were full and heavy only the day before. The Crown inspector at Hollowmere is a competent man. He has sent samples to the College of Natural Philosophy. I do not expect an answer that will satisfy me." Marrick's mouth tightened at the corner, the only motion that crossed his face. "I have seen this before."
"You have, my lord?" Kael asked.
"I have not." Marrick's voice did not change. "But my predecessor wrote of it. In the campaign logs from the Sundering, there are references to crops failing, livestock gone mad in their pens, wells turning to water that smelled of rot. The reports were dismissed as the ravings of a frightened garrison. I have not dismissed them." He uncurled one hand from behind his back and gestured toward the far wall. "Look at the map, Knight-Commander."
Kael crossed to the wall. The map was a great sheet of vellum, hand drawn, the rivers inked in blue and the marshlands left blank and ragged, as if the cartographer had not been able to bring himself to commit to any shape for the eastern reaches. Four villages had been marked with small black pins. They were spaced unevenly across the marsh border, but Kael could see, when he stepped back and half closed his eyes, that they fell into a rough line. The line pointed, by slow degrees, west. Toward Veranthos. Toward the capital itself.
"The wells," Marrick continued, "have begun to fail in two of those villages. The water rises black at the bottom of the bucket and clears only when it is poured. The livestock, in the worst affected holdings, will not eat. They stand in their byres and bellow until their throats are raw. Three have broken their stalls and run into the marsh. None have been recovered."
"And the people, my lord?"
Marrick turned to look at him fully for the first time. The stillness of those pale eyes made the back of Kael's neck prickle.
"The people have begun to disappear, Knight-Commander." Marrick's voice did not rise. "Not in numbers. Not in any pattern a man of sense would call a pattern. One from here, two from there. A grandmother who walked out of her cottage in the night and did not come back. A boy who went to check a snare and never returned. A mother who stepped from her porch to call in her daughter and was seen by no one again." He folded his hands behind his back once more. "Your office has been receiving the petitions. I am told you have read them."
Kael had read them. He had read them at the inn at Greymoor, by the light of a tallow candle, and he had read them again on the road between Greymoor and the capital, sitting up late in a hired coach with his coat pulled tight against the chill. The petitions had been written in hands that shook. The ink on the last one had been smeared, as if the writer had wept onto the page.
"I have, my lord," Kael said. "I had intended to ride east at first light tomorrow."
"You will ride east tonight." Marrick stepped to the table and drew a leather case from beneath it. He opened the case and laid a rolled document on the scarred wood. The seal at its head was not the garrison seal. It was the heavier, darker seal of the Crown itself. "This is your new commission. You will act as the Crown's sworn investigator in the matter of the failing villages, with the full authority of a magistrate of the second rank and the protections of a knight-commander of the royal line. You will answer to me. You will report to me, in writing, every three days. You will not enter the marsh without an escort, and the escort will be one of mine."
Kael looked at the document. He did not touch it.
"My lord," he said carefully, "the escort. Will I be given Captain Vale?"
Marrick's expression did not change, but something moved at the back of his eyes, a flicker that might have been amusement or might have been irritation. "Captain Vale is my forward scout. She will be assigned to your detail as my personal choice. She grew up in one of the villages that is now failing. I trust her loyalty to the Crown."
"And to you, my lord?"
Marrick's mouth did not move at all this time. "I trust that she understands where her duty lies, Knight-Commander. I trust that you understand it too."
The dust in the room had thickened. Kael could feel it against his teeth when he breathed. He could hear the faint creak of the vellum map behind him as the breeze from the high window pressed against it. He thought of the petitions, the smeared ink, the empty porches at dusk.
"I understand it, my lord," he said.
"Then take your commission and be ready to ride by the seventh bell." Marrick turned back to the window. His hands were clasped behind him again, and his shoulders were as straight as the sword at his hip. "There is one further matter."
"My lord?"
"There is a name that has surfaced in three of the four villages. A local woman. They call her the Briar Witch." Marrick spoke the title as if it tasted of ash in his mouth. "I want to know what she is. I want to know if she is responsible. And if she is, Knight-Commander, I want her brought to me."
The light in the room shifted. A cloud had crossed the sun beyond the high window, and the marble walls went from the color of old bone to the color of wet stone. Marrick stood in that gray silence, waiting, and Kael stood across from him with the commission on the table between them, and somewhere far to the east, in the marshlands, a field of blackened wheat waited for no man at all.
"Yes, my lord," Kael said. "I will find her."
The cloud moved off the sun. The marble warmed again, and the dust in the chamber settled into slow gold threads through the slant of light. Kael stood where Marrick had left him, his hand on the commission, his fingers remembering the shape of the wax seal even as he tried not to think about it.
"You are quiet, Knight-Commander."
Marrick had not turned from the window. He said it the way he said everything, as though he were merely noting the weather.
"My lord, I have a question," Kael said. "The villages. The four petitions I brought. Were any of the names on them known to you?"
For a long moment Marrick did not answer. His reflection in the glass was a still thing, armored, upright, and very far away from Kael's own. Then he turned. His face had not changed at all, but his eyes had. They had the look of a man who had been waiting to be asked precisely this question, and who had prepared the answer long before Kael had walked into the room.
"Three of them were known to me," Marrick said. "One was known to me very well."
He stepped forward. His boots were precise on the marble. He stopped at the table, and Kael saw for the first time that there was something else lying on the dark wood beside the commission. It had been hidden by the fall of a folded cloth, and Marrick's hand moved now to draw the cloth away.
It was a knife.
Not a working knife. Not a field blade. The handle was black iron, polished until it caught the light like a pool of ink. The pommel was worked in the shape of a closed fist. The sheath was lacquered wood, and along its length a single word had been burned into the grain in the old High tongue: Ember.
"This is the Veylan oath-blade," Marrick said. "It was carried to the marsh border by your father before you were born, and by his father before him, and by every Ashworth who has served this Crown in living memory."
Kael could not speak.
"It is not a gift," Marrick said. "It is a loan. And loans must be repaid."
His hand closed around the sheath and he lifted the blade from the table. He held it out across the wood, level with Kael's chest, and his face above the outstretched arm was calm and very cold.
"Kneel, Knight-Commander."
Kael did not kneel. Not yet. He stood looking at the blade, and he could feel the weight of it in the air between them as clearly as if it had already touched his palm. The word Ember. The closed fist at the pommel. He had seen that blade once, when he was a boy, in a cedar chest in the family hall at Ashworth Keep. He had not been allowed to touch it. He had been told, in the careful voice his father used for things that mattered, that the oath it carried was a blood oath, and that blood once given could not be taken back.
"My lord," Kael said, and his voice was not as steady as he would have liked. "Before I take it, I have to know. The name that was known to you very well."
Marrick did not lower the blade.
"Edric," he said. "Your brother."
The room went very still. The slant of light on the marble did not move. The dust hung where it was. Kael heard his own breath come in, and he heard it not come out again for what felt like a long time.
"Edric," he said.
"Edric Ashworth," Marrick said. "Younger son of Edric Ashworth the elder, late of Ashworth Keep. Volunteered for the eastern levy eleven months ago, against his father's express instruction. Last seen riding with a patrol of six along the river road toward the village of Hollowmere. Found three days later in a drainage ditch two leagues short of the village border, his throat cut from ear to ear, and a symbol burned into the skin of his chest in a shape no garrison scribe has been able to read."
Kael's hand had come up. He did not remember raising it. It was pressed flat against his own sternum, as if to hold something in.
"A witch-mark," Marrick said. "That is what the Crown has elected to call it. The Crown has also elected to call the manner of his death witch-magic. It is a useful word. It does not require us to admit we do not understand what we are dealing with."
"You knew," Kael said. "You knew it was my brother, and you let me stand here and read the petitions, and you did not tell me."
"I let you stand there because I wanted to see your face when I told you."
The words were not cruel. That was the worst of it. They were delivered in the same measured tone Marrick used for everything, as if he were merely describing a piece of furniture or a turn in the road. Kael looked at the blade in Marrick's hand. He looked at the closed fist at the pommel. He thought of Edric at seventeen, in the cedar-scented hall, trying to lift the same blade with both hands and laughing when he could not.
"You are the only Ashworth left who carries any weight in the southern courts," Marrick said. "Your father is too broken to ride. Your uncle is in the capital, and he will sign whatever he is told to sign. You, however, are a Knight-Commander of the Order of the Crown, and you have the ear of Prince Aldric Veranthos his own self, and when you speak, even in the south, men listen."
The name of the Prince rose in Kael's mind unbidden, and with it the face of Aldric as he had last seen it across a long table in the palace at Veranthos, calm and watchful, listening while Kael spoke of border matters that no one else had been willing to speak of. The Prince had not promised anything. He had only nodded, once, and said, Go and see what is there, and come back to me. Kael had taken that nod as a commission in itself, and now Marrick was standing in front of him with a blade and a blood-oath, and the two commissions were about to become the same thing.
"My lord," Kael said. "I will take the oath."
"Then kneel."
This time Kael knelt.
The marble was cold through the cloth of his trousers. He could feel the seams of the stone against his kneecaps. Marrick stepped around the table and stood over him, and the blade was held now in both hands, the point upward, the closed fist at the pommel level with Kael's eyes.
"The oath of the Veylan is simple," Marrick said. "There is only one question. You will answer it once. You will not answer it twice."
"I understand, my lord."
"The question is this. Will you, Kael Ashworth, Knight-Commander of the Order of the Crown, swear by your blood and by the blood of your house to hunt down the source of the curse that has fallen upon the marsh border, to find the woman they call the Briar Witch if she exists, to bring her to me living or dead, and not to rest, and not to lay down the burden of this oath, until the work is finished or your blood is spent?"
Kael looked up at the blade. The black iron of it caught the light, and the reflection in it was a small and very distant thing, his own face bent upward from the floor of a high room, with a man standing over him who held his brother's death in one hand and his family's honor in the other.
"I will," Kael said.
Marrick drew the blade from the sheath. The sound of it was a long thin whisper, like the breath of something waking up in a cold place. He reversed it in his hand and held the pommel out to Kael, the edge still toward himself.
"Take it by the fist," he said. "Cross your left palm over the edge. Press."
Kael took the pommel. The iron was cold and very heavy. He laid his left palm flat across the edge of the blade. The metal bit into the soft skin below the fingers. It was not a deep cut. It was a clean one. The blood came up slow and bright against the black of the iron, and Marrick stepped back a single pace, and nodded once, and did not smile.
"Rise, Knight-Commander," he said. "You are bound."
Kael rose. The oath-blade was in his right hand. His left was bleeding quietly onto the marble, and he did not bother to close his fist. He looked at Marrick, and Marrick looked back, and there was nothing in the Lord's face that suggested this had cost either of them anything beyond a few minutes of a bright afternoon.
"The first of the four villages is called Thornfield," Marrick said. "You will ride there by the seventh bell tomorrow. You will not take a retinue. A single man asks fewer questions than a column of horsemen."
"My lord," Kael said. "When I find her. What do you want done with her?"
Marrick was already turning back to the window.
"What is necessary," he said. "You will know it when you see it."
The light in the room had shifted again. The cloud was gone, and the marble was warm, and the dust was falling in slow gold threads toward the floor, and somewhere far to the east, in the marshlands, a field of blackened wheat waited, and somewhere closer, in a drainage ditch two leagues from a village whose name Kael had spoken aloud only once in his life, his younger brother lay in the dark with a witch-mark burned into his chest and no one to say his name.
Kael sheathed the oath-blade. He picked up the commission from the table. He did not bow, because Marrick was not looking at him, and he did not speak, because there was nothing left to say that would not sound like a boy's voice in a cedar hall, asking to be allowed to touch something he had been told he was not yet ready to hold.
He walked to the door. He opened it. The corridor beyond was cool and gray, and at the far end of it a page was waiting with Kael's traveling cloak, and the cloak was folded across the boy's arm in the precise way that page-boys were taught in the royal household, and Kael took it from him without a word, and the boy stepped back, and Kael walked out into the long light of the Veranthos afternoon, with his brother's blood on his hand and his brother's oath in his grip, and the road east already beginning to unspool in front of him like a length of dark silk.
The page boy held the cloak across his arm in the precise fold the royal household had taught him, and Kael took it without looking, because his eyes were still full of the oath-blade and the marble dust and the sound of his own voice making a promise he did not yet understand the price of. The boy stepped back. Kael walked. The corridor of the Veranthos garrison keep was long and cool and gray, and every servant he passed flattened himself against the wall without being told, because something in his face had changed since the door of the commander's office had closed behind him, and servants in royal garrisons learned to read such faces the way fish learned to read the current.
He descended the eastern stair. The light through the arrow-slit windows had gone the color of weak tea, and the dust was thick in the beams, and for three flights he thought of nothing, and then he thought of the cedar hall at home, and his brother at eight, practicing the sword-forms in the courtyard with a wooden blade that was too heavy for him, and the wooden blade had cracked against the practice post, and the boy had not cried, and their father had watched from the upper window and not come down, and the post had been replaced the next morning, and no one had ever spoken of it again.
Kael reached the chapel. It was a small stone room at the base of the keep, dedicated to whatever nameless thing the soldiers of the Veranthos border prayed to when they prayed at all, and it smelled of tallow and wet wool and the ghost of incense burned the week before. He pushed the door. The hinges complained. Inside, a single votive candle guttered on the altar, and the shadows pooled in the corners like dark water, and the silence was the kind of silence that listened back.
He drew the oath-blade. He set the commission on the altar beside the candle. He knelt on the cold stone, and the cold came up through his breeches and into his knees, and he bowed his head, and he said the words his father had taught him when he was seven and his brother was five and the world was still the shape it had been before the war.
"I swear by the name of my blood. I swear by the house that bore me. I swear by the brother I could not save."
The candle flame shivered. Kael watched the light move across the blade.
"I will find what took him. I will see it ended. And if the road costs me what the road costs, then the road is paid, and I will not be heard to complain."
He stood. The stone had marked his knees. He did not rub them. He sheathed the blade at his hip, and the weight of it felt different now, heavier in the hand, or perhaps lighter, the way a thing becomes lighter once one has agreed to carry it.
The door opened behind him. He did not turn.
"Magistrate Ashworth."
Captain Lisbeth Vale stood in the doorway with her scout's cloak still muddy from the morning ride, and her hair cut short in the northern fashion, and her eyes the color of river stones. She was shorter than Kael by a head, and broader across the shoulders, and she smelled of horse and woodsmoke and the first cold edge of the autumn marsh.
"Lordship."
"Captain."
"The Lord Commander sends me as your second for the marsh expedition. He was particular about that word. Second. Not guide. Not counsel. Second."
"I heard him."
"Did you."
It was not a question. Lisbeth stepped into the chapel, and her boots were loud on the flags, and she stopped two paces from the altar and looked at the commission lying there, and then at Kael, and then at the oath-blade at his hip.
"That is the old form," she said. "The one with the brother."
"Yes."
"My grandmother used it. Before she stopped saying anything at all."
Kael did not answer. Lisbeth waited, the way a good soldier waits for a civilian to make up his mind about something that does not need to be made up.
"The men," Kael said.
"Twelve who will ride. Twelve who will not ask questions until the questions are useful. Six from my own forward scouts. Six volunteers from the garrison horse. They know the marsh tracks."
"You trust them."
"I trust them to ride. I trust them to fight if they have to. I do not trust them to do anything clever, and I do not intend to ask them to."
"Good."
"There is a boy at the stables wants to come."
Kael frowned. "What boy."
"Stable boy. Name of Wren. Fifteen. Says he knows the marsh paths better than any map in the garrison library. Says he was born in a village two leagues from the eastern causeway. Says his mother was the seventh daughter of a seventh daughter, and his father was a witch-finder once, before the witch-finders were recalled."
"Is any of that true."
"His mother is dead. His father is dead. The rest of it is the kind of thing a fifteen-year-old says when he wants to be allowed to follow a magistrate into a place where magistrates have been known to stop returning."
"What do you advise."
"I advise we leave the boy."
"And."
"And if we leave the boy, I am going to have to tie him to a post, because he has already saddled his own horse and is pretending to check the girth strap."
Kael almost smiled. It did not reach his mouth, but it moved somewhere behind his eyes.
"Bring him."
"You understand he is fifteen."
"I understand."
"And that I am not his nursemaid."
"I understand that too."
Lisbeth nodded once. She turned and walked out of the chapel, and her cloak swung behind her, and her boots rang on the stone stairs, and Kael listened to the sound of her receding until it was swallowed by the larger sounds of the garrison preparing for a dawn ride, and then he was alone again, and the candle was guttering low, and the oath-blade was warm against his thigh.
He blew out the candle. He picked up the commission. He walked out into the dark of the lower keep, and the dark smelled of lamp oil and bread baking somewhere, and a dog was barking at the moon, and the moon was a sliver of dirty silver over the eastern wall, and the road to the marshes was a pale ribbon in the half-light, and somewhere along that road, in a drainage ditch, his brother lay with a mark on his chest, and Kael had sworn an oath on his name, and the oath was warm in his mouth like a coal he had swallowed and could not bring up again.
He did not sleep that night. He sat on the edge of his cot in the small chamber the garrison had given him, and he sharpened the oath-blade on a whetstone, and the sound of the blade on the stone was the only sound in the room, and the blade sang a thin high note, and he thought of nothing, and then he thought of his brother, and then he thought of a single rogue witch in the marshes, because that was what Marrick had told him, and Marrick was the Crown's man, and the Crown did not lie, except that the Crown lied all the time, and Kael knew that, and Lisbeth knew that, and the stable boy probably knew it too, and tomorrow morning they would ride east anyway, because the oath was sworn, and an oath sworn on a brother's name is not a thing one un-swears.
At first light the eastern gate of the Veranthos garrison opened, and twelve riders came out in a loose column, and at their head was Kael Ashworth on a grey mare with a magistrate's badge pinned to his cloak, and at his right shoulder was Captain Lisbeth Vale on a chestnut gelding with a scout's eye already turned toward the marsh, and behind them, on a pony that was too small for him, sat a fifteen-year-old boy named Wren who had no business being there and knew it and had come anyway.
The marsh lay ahead of them in the grey of the early morning. It smelled of rot and water and cold. It smelled, Kael thought, like the inside of a closed room in which something had recently died.
He touched his heels to the mare. The mare stepped forward. The column moved.
Ahead of them, a single rogue witch waited, and Kael was certain of it, because he had to be certain of something, and certainty was cheaper than doubt, and cheaper still was the truth.
