Merlyn ran his thumb across the last shard of bone and felt the crack. He was blind, but his hands read stone and bone better than any eye. This piece would carve like the others: it would split under the sacrifice-rune and misfire. A misfired sacrifice-rune killed the one who cut it. He needed his sight back, and the only way to earn it was this rune, the same rune his old master left unfinished before death took him. Every medium Merlyn owned was flawed. He stood in the workshop where the seer once studied. Dried herbs hung above him. His fingers found bottles, dice, and a heavy stone-bound book on the shelf. He knew that book by its carved covers. His master had marked pages in it for three hundred years of readers. Merlyn opened it and traced the raised lines with his fingertips. The pages spoke of the deep ash tree and the doorway inside its trunk. Beyond that doorway grew bone-white bark, pure enough to hold any rune. Merlyn had read of it as a boy. He had thought it a story. The door opened behind him. He knew the weight of the step. "You look like a dead man reading," Kjell said. The dwarf set something on the table. Coins rang against wood. Merlyn had taught Kjell to read runes years ago, and the man had never once softened a hard truth. "Every bone I own is cracked," Merlyn said. "I cut the rune, I die." "Then don't cut it." "Then I stay blind." Merlyn closed the book. "There is a wood past the ash-tree door. The bark there takes a rune clean." Kjell was quiet. "That door burns fools." "I am not a fool. I am tired of my father's hands." Merlyn's own hands began to glow, the knots on his forearms brightening as he pulled at the earth. "He worked that stone with no fingers left. He died before he saw. I will not." Kjell pushed the coins closer. "Payment for the wild folk, if the door leads to them. Take it." Merlyn gathered the coins into his apron. He found the ash tree by the hum in the ground, the way roots pull at buried magic. His hand met bark, then open air where the trunk should have been solid. The doorway breathed cold at his face. He reached through and touched a young tree on the far side. The bark peeled away smooth and whole. No crack. No flaw. He pressed his thumbnail into it and felt it hold. Merlyn drew his hammer and set the fresh bark against a flat stone. He cut the first line of the sacrifice-rune. The bark took it clean, no split, no misfire. His hands would live to finish it. But cutting the full rune meant giving something in return. The book had named the price. He had the medium now. He did not yet have what the rune would demand.

Merlyn set the fresh bark down and read the rest of the rune from his master's stone-bound book. His fingers traced the raised lines. The book named the price plain: the sacrifice-rune took a life to seal. Not always the carver's. It fed on whatever stood nearest when the last line closed. A carver who worked alone had no guard against it turning back on him. He needed a witness. Not to help cut, but to hold him steady when the rune reached for a life. Someone who could pull the price away from his own body if it turned. He knew one man who could read the work and would not flinch. The workshop door opened. Merlyn knew the short, heavy step. "You still smell like burnt bone," Kjell said. The dwarf had taught himself to read runes in the mountains, paid an old man three hunts of silver for it. He owed Merlyn nothing but old debt. He set his axe against the wall. "You cut it yet?" "The rune wants a life," Merlyn said. "When the last line closes, it takes whatever is closest. If I stand alone, that is me." Kjell was quiet. "So you need a body between you and it." "I need a witness bound to hold the price off me. You read the work. You can watch the lines and pull it wide." "Bound how?" Merlyn slid a rune-coin across the table. Its stamped face was worn smooth. "Blood on the coin. You hold it. The rune reads you as guard, not offering. If it turns, it burns the coin, not either of us." Kjell picked up the coin. He turned it once. "And if the coin fails?" "Then one of us pays." Outside, something crashed through brush. A dire boar broke from the trees and threw itself at the workshop steps, tusks scraping wood. Kjell had it. He drew a throwing knife and put it through the boar's eye in one throw. The beast dropped on the porch, twitching, then still. Kjell looked at the dead boar. Then at Merlyn. "There's your body between you and the rune," he said. "A live thing, closer than either of us." Merlyn's hands went still. The book had said a living offering. He had thought it meant a person. It meant only a life. They dragged the boar inside. Merlyn pressed his palm to the coin, then to Kjell's hand, and bled a line across both. He set the boar against the stone, close, and put the bark under his hammer. His forearms glowed. He cut the last line. The rune took. The boar's body seized and went cold in a breath. The bark held, whole, the full rune burned into it clean. Kjell's coin was hot but unbroken. Merlyn's hands shook. He had a finished sacrifice-rune now. But it was carved for a boar's life, not the greater price his sight would truly cost.

The boar's life had not been enough. Merlyn knew it the moment the coin cooled in his palm. Two days later, in the seer's workshop, he felt the truth in his own blood. The rune-coin lay against his chest on its cord, and it was drinking from him. His hands trembled at the forge. His breath came thin. The rune had sealed for a boar's price, but the sacrifice it wanted was greater. Now it took the rest from the carver. He traced the coin's face. The blood-line he had cut across it was warm, feeding. A slow leak from his own veins to fill what the boar could not. If he let it run, it would empty him the way forge-sickness had emptied his father. The door opened. The short, heavy step. Kjell. "You've gone gray," Kjell said. He set his axe by the wall. "Not old-gray. Sick-gray." "The coin is bleeding me," Merlyn said. "The boar was too small. The rune reached past it and found me." Kjell crossed the room. He lifted the cord, felt the coin's heat, and dropped it. "Cut the cord." "Cut it and the rune turns loose. It takes whatever stands closest." Merlyn's blind face turned toward him. "That is you." Kjell was quiet. Then he pulled a rune-marked coin from his belt and set it on the table. An old one, stamped, worn smooth. "Feed it this instead." Merlyn's fingers found the coin. Metal, not flesh. "It wants a life, not silver." "Then bind the debt to the metal." Kjell's voice did not rise. "You carve. I hold. Same as before. Read the second coin as the offering. Move the price off your blood and onto it." Merlyn thought of his father, working the stone with ruined hands. He would not die feeding a coin. He set both coins together on the anvil, his own and the old Viking one. He pressed his palm across them and opened the blood-line again, wider. Kjell laid a hand over his wrist and held it steady. "Read the lines," Merlyn said. "If it turns to me, pull it wide." He raised the hammer. His forearms glowed. He struck a binding rune into the old coin, joining it to the first. One strike. Two. The bleeding coin flared hot, then dragged at the new metal instead of his chest. The old coin cracked down the middle. Both halves went cold. The cord slackened. Merlyn's breath came back into him all at once. He sat down hard on the bench. His hands still shook, but the pull was gone. The debt had passed into the broken coin and died there. Kjell picked up the two halves and looked at them. "It's spent," he said. "But the sight-rune still holds a boar's price. Not yours." Merlyn nodded slowly. The rune was safe now. But it was still too weak. To buy back his eyes, he would have to pay the greater price himself.

The broken coin lay cold on the anvil, and Merlyn's strength had come back. But the sight-rune still held only a boar's price. To buy his eyes, he needed the greater price, and he did not know its name. His master's book might hold it. He had carried the heavy volume for weeks and not dared open it to that page. Now he did. He worked in the seer's workshop by feel, running his fingers over the raised marks. The book was a slab, its covers cut like temple pillars, its pages stiff as stone. Merlyn read the sacrifice-page slowly. The rune for sight demanded a thing beyond blood. It wanted heart-wood from the ash-tree doorway, cut living, still wet with sap. His master had written the price. He had not written where such wood could be found. "It names the cost," Merlyn said. "Not the place. He left that out." Kjell stood by the wall. Two more men had come with him from the deep roads. Merlyn knew their steps. Thorin, old and heavy in his mail. Thorgar, wide as a door, smelling of ash and salt. They had fought under the mountain and lived. Now they crowded the small room. "Read it again," Kjell said. Merlyn traced the marks. Then his thumb caught the border. Along the page's edge ran a ring of small stones, carved in a circle. Standing stones. He had felt them before and thought them only decoration. Now he counted the runes cut into them. "There is a ring drawn here," Merlyn said. "Round the page. Old stones. Each one marked." Thorin leaned close. His iron beard-rings clicked. "I know that ring. North of the pass. Twelve stones in a circle. My clan passed it every spring." He stopped. His voice went flat. "An ash-tree grows in the middle of it." Merlyn's hands went still. The doorway. The living heart-wood. It stood inside the stone ring Thorin had walked past his whole life. "The place was never in the words," Merlyn said. "It was in the picture. He hid it in the border." Gunnar spoke from the doorway, blunt. "Then the tree is real. And so is the price." "A living cut," Merlyn said. "Still wet." He closed the book. The pillars pressed cold under his palms. He had the name of the price and now the place to pay it. That was more than his father ever held. His father died blind, bent over sealed stone, and never got this far. Merlyn stood. His forearms glowed faint as he steadied himself. "Then we go north," he said. "To the ring of stones." Thorin picked up his axe. "I'll take you. I know the road." The way was found. But the ash grew inside a broken circle of old markings, and no book told him what still guarded it.

The stones stood where Thorin said. Merlyn felt them before he reached them, twelve tall shapes ringed in cold grass. His fingers found the nearest one and traced the marks. Old runes, worn soft by rain. In the center, the ash-tree waited, its bark alive under his palm. Beside him Kjell, Thorgar, and Gunnar spread out, boots crunching. But Merlyn's master's book had warned of a guardian, and the passage naming it had crumbled to dust. He did not know what watched. "Something guards this place," Merlyn said. "The book named it. I could not read the name." Gunnar set a hand on his hammer. "Then we watch the trees." Merlyn walked to the ash and drew his own hammer. He pressed his blade to the living wood. If the guardian would not show itself, he would force its hand by cutting. The grass moved. A small shape rose from the roots, no taller than a child, its hair a knot of leaves and green shoots. Two eyes burned orange in its face. It stepped between Merlyn and the tree and did not flinch. "Take your iron off my bark," it said. Kjell moved his hand to his axe. Merlyn lifted an open palm to stop him. He knew a keeper when he heard one. This was no beast to fight. "You tend it," Merlyn said. "I do." The keeper touched the trunk. "This tree cut its water last year. Two saplings downhill died for it. I left a tree once, thinking it dead. I was wrong. I will not be wrong again." The orange eyes did not blink. "You want its heart-wood. Cutting it living kills it." "I need it living," Merlyn said. "For my eyes." He touched the leather over his blind sockets. "My father died blind. His father too. This wood is the price to end that." The keeper was quiet. "Your want does not matter to the tree." Merlyn knelt. He pressed both palms to the roots and let his tattoos glow. He read the tree the way he read a seal, feeling for its lines. He found the drought-scars, the shut channels, the crown dying from the top down. "It is sick," Merlyn said. "The roots strangle each other. Left alone, it dies whole. Let me cut the dead crownwood. Free the rest. The tree lives. I get my heart-wood from the part already dying." The keeper stared at him. Then it climbed the trunk and pressed an ear to the high branches. It came down slow. "The dead wood chokes it," the keeper said. "You read true." It stepped aside. "Cut only what I mark. No more." Merlyn struck. His hammer bit the dead crownwood the keeper marked. A pale chunk fell into his hands, still wet with sap. Living heart-wood, taken without killing the tree. He had the last piece. But the wood was not the whole price. The rune still demanded a life, and no boar would pay it now.

Merlyn held the heart-wood in both hands. The sap still ran warm against his palms. He had the wood. He had the rune cut and ready. But the sight-rune demanded a life to seal it, and no boar walked this cold ring of stones. He would not spend an innocent for his eyes. That thought closed like a door. Thorin stood near the tallest stone, arms folded. He had guided Merlyn here, knowing his own father died blind and bent. Kjell crouched by the ash, watching the keeper. Gunnar and Thorgar spread wide, hands near their steel. "The rune wants blood," Merlyn said. "A life. I will not take one that isn't owed." "Then it stays unsealed," Thorin said. "You go home blind." "No." Merlyn set the wood down and knelt over his master's carved rune. He ran his fingers along its lines the way he read a seal. He felt the cut for a full life. And under it, faint, a second groove he had missed. His master had cut two paths, not one. "There's a lesser channel," Merlyn said. "He hid it. A smaller price. Not a life whole. A part of one." Kjell rose. "What part." Merlyn pressed his thumb to the second groove. The rune answered. It wanted years, not a heart. Years off the one who sealed it. His own years. He would trade them for the sight he had lost. "Mine," he said. "It takes from me. Not enough to kill. Enough to age me." Gunnar's hand left his hammer. "You're sure it's not a trap." "I know his hand." Merlyn traced the corner. "He cheated the fourth quadrant, same as always. The groove is true." Thorin said nothing. He drew a slow breath through his nose. Merlyn fit the heart-wood into the rune's mouth. He struck it once with his hammer. The wood took the cut clean and did not crack. He pressed both palms flat and pulled earth magic up through his arms. His tattoos lit white. The rune drank. It pulled from his chest, from his bones, a cold draining like a wound bleeding inward. His knees hit the grass. His beard-stones clacked as he shook. He did not stop pulling. Then the leather over his eyes grew warm. Light bled through it, gray at first, then sharp. Merlyn tore the blindfold off. He saw the ash-tree black against a pale sky. He saw Kjell's teeth-strung beard, Thorin's iron rings, the keeper watching with orange eyes. His hands were his hands, but the skin had thinned. Gray had crept into his beard where copper had been. "I see," Merlyn said. Kjell knelt beside him. "You're older." "Ten years, maybe." Merlyn stood, unsteady. He looked at the carved rune. It had drained the wood too, and the ash beyond it stood dead-still. The keeper stepped toward the trunk, ears pressed to the bark, and made a low sound. Whatever the rune had taken, it had not stopped at Merlyn.

Merlyn saw the dead ash and the keeper pressed to its bark. His new sight was clear. His body was not. His legs shook under him, and the ground pitched. He reached for the tallest stone and missed. Ten years had left his chest hollow. His hands, once strong on the hammer, now trembled like an old man's. Kjell caught his arm. "Sit." "I can't stay here." Merlyn's voice cracked. "The keeper. He'll turn on us." He looked at the leaf-haired keeper, who had gone still by the trunk. Orange eyes fixed on Merlyn. The rune had drunk the tree dry, and the keeper knew it. Thorin planted his axe in the grass. "Then we move. Now." He watched the keeper, not Merlyn. "That one won't stay quiet long." Merlyn tried to rise. His knees folded. He hit the cold ground and stayed there, breath rasping. "I can't walk." The words shamed him. He had spent his years to see. Now he could not carry himself from the ring. Gunnar knelt and gripped Merlyn's shoulder. His soot-black hand felt the thinned muscle there. "Bone's fine. Meat's gone." He said it flat, the way he named cracked iron. "You need carrying." "There's no time to carry me slow." Merlyn pointed a shaking finger at the keeper. "He'll wake the whole wood. We go fast or not at all." Thorgar stepped over the dead roots. He was wide as a door, bear pelt heavy on his shoulders. He looked at Merlyn on the ground, then at the keeper, then said, "Fast, then." He bent, hooked one thick arm behind Merlyn's knees and one behind his back, and lifted him like a sack of grain. "Put me on my feet," Merlyn said. "Your feet don't work." Thorgar turned toward the gap between the stones. "Argue when we're out." The keeper made a low sound and stepped from the trunk. Thorin swung his axe up between them. "Go," he told the others. He backed after them, facing the keeper the whole way, iron rings clacking in his beard. Kjell led. Gunnar took the rear beside Thorin. Thorgar carried Merlyn through the gap and down the slope, fast, his breath even under the weight. Merlyn watched the ring shrink behind them. The keeper did not follow past the stones. It stood at the edge of its dead tree and let them go. They stopped when the ring was gone from sight. Thorgar set Merlyn down against a rock. Merlyn sat, drained, and drew his master's tome from his pack. The stone-toned cover was cold in his weak hands. He could read it now with his own eyes. But his fingers shook so badly the pages blurred. "I have my sight," Merlyn said. "I traded the strength to use it." He closed the book. "I need my body back before the wood decides to hunt us."

Merlyn sat against the rock and tried to pull earth magic through his brands. Nothing came. The dead ash had swallowed his last thread of power. His tattoos stayed dark on his forearms. He could see the wood now with his own eyes, and he could see the branches begin to shift. "They're coming," Merlyn said. "Roots and vine folk. The tree drank them dry, and now the wood wants payment." He pressed his hand to the ground. No warmth answered. "I can't channel. There's no live earth to pull from here. All of it near the ring is dead." Kjell crouched beside him. Teeth and claws rattled on his beard. "You broke worse seals with me watching. Find something living." "Nothing near is living." Merlyn's voice shook like his hands. "The rune killed the tree and everything the tree fed. I'm empty." Thorin stood over them, axe ready, watching the tree line. "Then someone gives you a source." He said it plain, as if handing over a tool. He knelt and set his bare palm on Merlyn's brand. "Take it from me. I've bled for worse." Merlyn shook his head. "I can't pull life from a man and stay clean. The rune already cost me ten years." Gunnar had said nothing. He walked to a low stone shelf beyond the rock and struck it once with his hammer. The blow rang. He struck again. On the third hit the surface cracked, and dark water welled up from beneath. "Live spring," Gunnar said. "Stone told me. Water's still moving down there." He pointed. "Old rock. Never touched by the tree." Merlyn crawled to the wet crack. He pressed both palms flat to the cold, running stone. He reached down, past the dead crust, into rock that had never fed the ash. Deep water pulsed against his fingers. His brands flickered. Then they caught and burned bright gold up both forearms. The first vine broke from the ground three paces off. Merlyn slammed his hammer against the stone and drove a rune into the wet rock. Earth magic answered him now. A wall of loose stone heaved up and pinned the vine flat. He carved a second sign. The ground around the camp hardened to slab. The leaf-haired keeper did not cross it. It stood at the edge of the dead wood, orange eyes on Merlyn, and stepped back into the trees. Merlyn sagged over the spring, but his hands held steady on the hammer. "I have a source now," he said. "Live rock, not dead tree. I can channel again." Thorgar hauled him up by the pelt. Merlyn stood on his own feet for one breath before his knees gave. He caught the stone shelf. "Fixed one thing," Thorgar said. "Not your legs." Merlyn looked at the tome in his pack, then at the woods closing behind them. His power was back. His body was not. "Then we carry the book," he said, "and find deeper stone before the wood tries again."

The group carried Merlyn deeper into the stone. Thorgar hauled him by the pelt through a low tunnel, the tome heavy in Merlyn's arms. His legs still would not hold. Behind them, root and leaf scraped rock. The leaf-haired keeper had followed them off the dead ground and into the dark. It wanted them dead for killing its ash tree, and Merlyn's last channeling had drained him to the bone. "It's still coming," Merlyn said. He pressed a palm to the tunnel floor. A thin warmth answered, deep and far off. "There's live rock below. But I'm too spent to reach it. If I pull now, it takes years I don't have left." Kjell crouched by his old teacher. The troll teeth on his beard clicked against the stone. For years Merlyn had taught this hunter to read the signs he could not carve himself. Now Kjell looked to him for the answer. "You don't reach it," Kjell said. "You seal the tunnel behind us. Trap it out." Merlyn shook his head. "A wall won't hold. It grows through stone." Then he stopped. His fingers found a seam in the floor where old rock met older. "Unless the wall drinks it." He looked up. "I carve a rune that pulls the tree-life out of it. The keeper is made of the wood I killed. Cut its source, and it falls." "Then carve," Thorin said. He set his back to the tunnel and lifted his father's axe. Iron rings shook in his gray beard. "I'll hold it while you work." Gunnar knelt and struck the floor with his hammer. The blow rang. He struck again and the stone split, showing wet black rock beneath. "Live rock," he said. "Water still moves. Draw from here, not from you." Merlyn pressed both hands to the wet crack. His brands caught and burned gold. He raised his hammer and drove a rune into the split stone. The keeper reached the tunnel mouth. Thorin met it. His axe bit into vine and it recoiled, orange eyes fixed on Merlyn. Merlyn cut the second half of the rune. The sign pulled. Green light bled from the keeper's limbs and ran along the floor into the stone. The creature's leaves browned. Its vines went slack. It sank to the rock, curled small, and stopped moving. Thorin lowered his axe. The tunnel went quiet but for water. Merlyn slumped over the crack. His hands still gripped the hammer. "It's dead," he said. "Drank the last of the wood out of it. The forest won't send another. I broke its keeper." Thorgar lifted him upright. Merlyn stood one breath, then his knees folded. He caught the wall. "Killed the thing chasing us," Thorgar said. "Still can't walk." Merlyn looked at the tome in his arms, then down the dark tunnel. His sight was his own now. His strength was not. "Then we go down," he said, "to the live rock, before my legs cost us more than years."

Thorgar hauled Merlyn down the tunnel by the pelt. The floor sloped, wet and black. Merlyn held the stone-bound tome against his chest. His legs dragged useless behind him. Far below, water moved through rock. He could feel it now with his own eyes, a faint gold thread in the dark. Live rock. Deep. Too deep to touch. "Stop," Merlyn said. Thorgar set him against the wall. Merlyn pressed his palm to the floor. The warmth answered, but it lay under a body of hard stone. "The water's below us. I can't reach it. If I channel from here, I pull it up through the whole shelf. That costs me years I don't have." Gunnar knelt and struck the floor with his hammer. The blow rang dull. He struck again. No split. "Solid," he said. "Old rock. Runs deep." He set his ear to the stone, listened, then shook his head. "Water's there. But it's under a shelf thick as a wall." Kjell crouched by his old teacher. The troll teeth in his beard clicked. For years Merlyn had taught this hunter to read the runes he could not carve himself. Now Kjell looked to him again. "You've got the tome," Kjell said. "And your own eyes to read it. Use them." Merlyn opened the stone-bound book. He turned the pages himself, tracing the carved borders with his finger. His sight was clear now. That was the whole cost of it. He found a rune drawn small in the margin, a channel-sign meant to move power through stone without spending the caster. "A conduit," he said. "I don't pull the water. I make the rock carry it to me. The stone pays the reach, not my blood." "Then carve it," Thorin said. He set his back to the wall, father's axe across his knees. Iron rings shook in his gray beard. "We're not going deeper if you can't walk out." Merlyn raised his hammer. His arms shook. Gunnar gripped his wrist to steady the swing. Merlyn drove the first half of the sign into the dry shelf. Then the second. The brands on his forearms caught and burned gold. The rune pulled. Gold light ran down through the rock, down and down, then rose again. It came back carrying the deep water's warmth. Merlyn drank it in. He did not spend himself. The stone spent for him. Warmth spread through his legs. His knees firmed. He set a hand to the wall and stood. He held. Then he took one step, and another, without falling. "It holds," Merlyn said. He looked at the tome in his hands, then down the black tunnel where the gold thread ran. "I can walk. And I can carve from stone now without paying blood." Gunnar struck the floor once more. This time the rock split. Wet black stone showed beneath, water moving fast under it, and a hard cold air rising up from below.

Merlyn stood at the edge of the broken shelf. Water rushed in the dark below. His legs held him now, and the conduit rune spared his blood. But his eyes ached. A gray film crept across the gold thread of live rock he had read so clearly moments ago. He blinked. The thread dimmed, then returned. His sight was failing. Slowly. The greater cost of the rune had not finished with him. "Something's wrong," Merlyn said. He pressed a knuckle to his eye. "My sight comes and goes. The rune took ten years. I think it means to take more." Kjell crouched beside him. The troll teeth in his beard clicked. For years this hunter had trusted Merlyn to read what he could not. Now he watched his old teacher rub his eyes like a man going blind again. "Then read the book," Kjell said. "Find the fault. You always could." Merlyn opened the stone-bound tome across his knees. He turned the carved pages himself. His finger traced the border his master had cut. Near the sight-rune he found a mark he had missed before, small and half-buried in the pillar design. He leaned close. The gray film thickened. He could not tell the rune from the shadow. "I can't see it," Merlyn said. "That's the fault itself. The rune bleeds sight to feed its own hunger. If I don't seal it, I go blind for good." Gunnar knelt by the split rock. He set his ear to the wet stone, then struck it once with his hammer. "Live rock's close now," he said. "Strong. Stronger than the shelf above." He looked at Merlyn. "Use it." Thorin stood at the wall, his father's axe across his arms. Iron rings shook in his gray beard. "Carve, then," he said. "We didn't drag you this deep to bury you here." Merlyn pressed his palm to the broken edge. The deep water's warmth answered through the fresh stone. He read the buried mark not with his eyes but with his tattoos, letting the earth magic trace its shape. A sealing-sign, meant to close the wound the sight-rune had left open. He raised his hammer. Gunnar gripped his wrist and steadied the swing. Merlyn drove the first half of the sign into the wet rock. Then the second. The brands on his forearms burned gold. Power ran down into the deep water and rose again. It did not spend his years. The stone paid the reach. The gray film pulled back. The gold thread sharpened. Merlyn saw the tome's carved letters, then the split rock, then Kjell's scarred face, each one clear and steady. He held his hand before his eyes and counted the calluses. "It holds," Merlyn said. "The bleeding's stopped. My sight is mine now, and it stays." Thorgar hauled a slab aside. Cold air rushed up from the split, and below, the water ran fast toward some deeper dark.

Thorgar heaved the last slab aside. Cold water filled the passage below, black and deep. Merlyn knelt at the edge and read the stone with his tattoos. The gold thread of live rock ran under the flood and vanished. There was no ledge, no dry path. The way forward lay through the water, and it ran too far to hold one breath. "That's the only door," Thorgar said. He wiped his hands on his pelt. "Under the water. I felt no other." Merlyn pressed his palm to the flood. His body was still weak from the years the rune had taken. He could barely stand a full watch. Cold water like this would seize his chest and drag him down. "I can't swim it," he said. "Not as I am. My lungs would fail before the far side." Kjell crouched beside him. The teeth in his beard clicked. For years this hunter had trusted Merlyn to read what he could not. Now he watched his old teacher measure a drowning. "Then don't swim," Kjell said. "Carve." Merlyn turned. "Carve what?" "A rune to hold air. You seal stone. Seal a breath into your chest." Thorin planted his father's axe against the wall. Iron rings shook in his gray beard. "Or float," he said. "Seal the flood so it lifts you." He looked at the dark water and said no more. Merlyn opened the stone-bound tome across his knees. He turned the carved pages himself, his sight clear and steady now. He found a rune shaped like a shut mouth, cut into the border of a page. A breath-hold sign. His master had marked it for divers who worked the drowned seals. But it needed a stone to bind it, and the price would drain his blood if he had no live rock to pay. "There," Merlyn said. "But I need the live rock. If I channel from myself, I'm too weak. It could stop my heart in the water." Gunnar set his ear to the wet stone at the edge. He struck it once with his hammer and listened. "Live rock runs right under the flood," he said. "Strong. It'll take the reach." Merlyn set his hand flat on the drenched stone. The warmth answered up through his palm. He raised his hammer. Gunnar gripped his wrist and steadied the swing. Merlyn drove the first half of the shut-mouth sign into the stone. Then the second. The brands on his forearms burned gold. The power ran down into the live rock and rose again. It did not spend his years. His chest filled and held. The air stayed, sealed, as if his lungs were stone. Merlyn breathed once and felt no need to breathe again. "It holds," he said. He rose and stepped into the black water. "I can cross now. Follow the thread of live rock below. It leads on." He went under. The cold gripped him, but his chest did not.

Merlyn swam the black water with the thread of live rock glowing below him. His sealed chest held steady. Then the water shifted. Something large moved in the deep, off to his left. A cold swell pushed past him. He turned in the dark and saw a pale shape roll through the flood, long as three men. It circled toward him. He reached for his hammer and knew the trap at once. The breath-rune held his lungs. If he stopped channeling it to strike a defense-rune, the water would flood in and drown him. If he held the breath-rune, he could not spare the power to fight. He could do one or the other. Not both. The pale thing came around again, faster. Above him, at the water's edge, Kjell saw the swell break the surface. The teeth in his beard clicked once. For years this hunter had trusted Merlyn to read what he could not. Now he trusted himself. He drew a silver-tipped knife and dropped into the flood beside his old teacher. Merlyn felt the water move. Kjell swam down to the live rock and set his bare palm flat on it. He had learned runes from a mountain man, three hunts' worth of silver paid in silence. He knew a strike-sign. He drove his knife into the stone and cut it fast, blood clouding the water from his knuckles. The rock lit gold under his hand. The defense-rune fired. A hard pulse rolled out through the water. It struck the pale beast broadside and threw it back against the far wall. The thing thrashed, stunned, and sank into the deeper dark. Merlyn held his breath-rune the whole time. He never let it slip. Kjell had paid the price from his own hand so Merlyn would not have to choose. They broke the surface on the far side together. Thorgar hauled them both onto the wet ledge. Gunnar knelt with his hammer ready. Thorin stood over them, his father's axe raised at the water. Kjell coughed and held up his hand. His knuckles ran red where the knife had torn them. "It's stunned," he said. "Not dead. It'll wake." Merlyn let the breath-rune go at last. Air rushed from his chest. He gasped and drank the cold air of the far tunnel. "You carved in the water," he said. "With no live rock to read." "I read it," Kjell said. He wrapped his torn hand in leather. "You taught me enough." Gunnar set his ear to the wet stone. He struck it once and listened. His face went hard. "Water's rising," he said. "Fast. The far pool is filling." Merlyn looked back at the flood. The beast slept in it, and the tide was climbing. They had crossed, but the way behind them was closing, and the thing in the water would not stay stunned for long.

The water climbed the ledge behind them. Merlyn pressed his palm to the wet stone and felt for live rock. There was none. The tunnel forward narrowed to a low mouth, and water already ran into it. In minutes the way would drown. He had crossed one flood only to meet another, and this one would seal them in before he could cut a single sign. Gunnar struck the wall with his hammer and listened. "Dead rock," he said. "All of it. No spring, no water-vein I can use." He tried three more spots. Each rang flat. Merlyn opened the stone-bound tome across his knees. Its cracked gray covers were slick with spray. He read fast, hunting a sign that did not need live rock. The pillar-carved margins held old marks his master had copied long ago. One caught him. A sign that pulled power from a struck edge, not from the earth beneath. "I need iron," Merlyn said. "Something forged, something struck ten thousand times. It holds the memory of the hammer. I can draw from that." Kjell unwound the leather from his torn hand. He looked at the flooded mouth, then at his old teacher. "You mean my axe." "Rune-carved. Worked by a smith for years. It will answer." Thorin gripped his father's axe closer. "Not that one," he said. Then he glanced at the rising water and said nothing more. Kjell drew his rune-carved axe from his belt. He had carried it through trolls and draugr, and Merlyn knew what it cost him to hold it out flat. "Cut fast," Kjell said. He set the axe-head against the tunnel floor and pinned it there with his boot. "It'll wake soon." He meant the pale beast, still stunned in the flood behind them. Merlyn laid his hand on the cold iron. His arm tattoos lit gold. He raised his twin-headed hammer and struck the axe-head three times, cutting the drain-sign into its flat. The iron rang. Power poured up his arm, sharp as a coal. He turned to the tunnel mouth. Water sheeted across it now. He pressed both palms to the stone above the flood and carved the second sign into dead rock, feeding it the axe's stolen strength. The wall lit. Stone cracked and heaved. A slab fell inward and the water poured off sideways, draining into the broken gap. The low mouth opened wide and dry above the pull of the flood. "Through," Gunnar shouted. "Now." They climbed through the broken wall one by one. Behind them the pale beast rolled in the deep and woke. Kjell went last, his axe left dead and dark on the ledge, its runes burned clean. He did not look back at it. Merlyn stood in the new passage, the tome shut under his arm. His sight held. But the drain-sign had bled the iron cold, and he knew now that dead rock alone would never carry him to the sight-rune's end.

The new passage ran dry, but the drained wall behind them shook. Merlyn turned. Through the broken gap he had cut, the flood still churned. In it, the pale beast rolled and thrashed. Its long body scraped the stone. The stun was wearing off. Soon it would reach the gap and come through after them. Merlyn's arms hung heavy. The last carving had bled him hollow. He could not raise another sign in time. "It's waking," Kjell said. He drew a throwing knife, though he knew iron meant nothing to the thing. "Merlyn. Can you seal the gap?" "No live rock," Merlyn said. "No iron left. I've got nothing to draw from." His tattoos lay dark on his arms. He had struck the axe cold. There was no forged metal near, no spring, no vein. Thorgar stepped past him toward the gap. He gripped both bearded axes. He had killed a sea beast in a drowned cave, alone. He looked at the pale thing thrashing in the water and named it plainly. "Wrong shape," he said. "Like the one that took my brother's crew." He set his feet at the broken wall. "You can't hold it," Thorin said. He came up beside Thorgar, his father's axe raised. The old dwarf's knees shook, but he planted them like stone. "Not with steel. It doesn't die from steel." Merlyn looked at the tome shut under his arm, then at the broken slab he had dropped to divert the flood. The stone lay wedged half in the gap. He remembered the drain-sign, still fresh in his mind. Iron held the hammer's memory. But so did worked stone, cut and struck by hands. "Gunnar," he said. "This slab. Was it shaped? Worked?" Gunnar knelt and ran a scarred palm across the fallen stone. He tapped it once, listened. "Dressed," he said. "Chisel marks. Old, but true. Someone squared this." "Then it remembers the tool." Merlyn dropped to his knees. He pressed both palms to the dressed stone. Faint gold woke in his tattoos, thin as a thread. Not live rock. Worked rock, holding the ghost of the mason's blows. He raised his hammer and cut a wedge-sign into the slab's face. The stone rang under the iron. Power crept up his arm, weak but enough. He fed it into the gap. The dressed slab groaned and slid. It jammed hard into the broken mouth. The pale beast struck the far side. Stone held. Water hissed through a hairline crack, then stopped. "Sealed," Gunnar said. He struck it once. It rang solid. Merlyn sat back against the dry wall. His hands shook. The gap was shut, the beast walled off in the flood. But the wedge-sign had bled the worked stone gray and dead, same as the iron before it. Every source he touched burned out and left him weaker. He was closer to the sight-rune's end. He was also running out of things to break.

The sealed slab held, but not for long. Merlyn heard the pale beast strike it again. A crack split the dressed stone. Water hissed through and pooled at his knees. He had walled the thing off with a wedge-sign, but the stone was gray and dead now, all its strength spent. He needed a killing sign to end the beast for good. His arms would not lift the hammer. Every source he had touched lay burned out around him. "It's breaking through," Kjell said. He crouched by the slab, one hand flat on the shivering stone. "You carved this. Can you carve the thing that kills it?" "I've got nothing to pull from," Merlyn said. His tattoos lay dark. "No live rock. No iron. The stone's dead." Thorgar set his feet at the gap, both axes ready. "Wrong shape," he said, watching the pale body roll behind the crack. "Steel won't hold it. But I'll slow it." Thorin planted his father's axe beside him. His knees shook under him. "Slow it for what? He's got no power left." Then Gunnar dropped to a knee. He unlaced a small pouch from his belt and spilled it into his palm. Old Viking coins, edges worn, faces stamped with runes and knots. "Forged," he said. He pressed one into Merlyn's hand. "Struck by a hammer, same as your iron. They hold the memory." Merlyn closed his fingers on the coin. It was warm from Gunnar's body. Worked metal, cut and stamped by some long-dead smith. A thread of gold woke in his tattoos, thin but real. He spread the coins on the wet floor in a row. "How many?" "Nine," Gunnar said. "All I carry." "It'll be enough for one sign." Merlyn raised the hammer. His arm burned. He struck the first coin, then the next, cutting a killing-rune across all nine faces. Each blow rang. Each coin darkened as the power bled out and crept up his arm. The row went dull, one after another, spent. The slab cracked wider. A pale limb pushed through the gap. Merlyn pressed both palms to the broken stone and drove the killing-sign into it. Gold flooded his tattoos, then guttered. The rune bit deep. The stone glowed white where the beast touched it. The creature shrieked and thrashed. Then it went still. Its long body slid down the far side of the slab and sank in the flood. "Dead?" Thorin asked. Gunnar struck the slab. It rang solid. "Dead," he said. Merlyn slumped against the wall. Nine dead coins lay scattered at his knees. His hands would not stop shaking. The beast was gone, but so was the last forged thing they carried. He had spent Gunnar's coins, his iron, his worked stone. Ahead the tunnel ran dark and empty. He could read his master's tome with his own eyes now. But when the next wall rose, he would have nothing left to break it with.

The pale beast sank behind the slab, and the tunnel went quiet. Merlyn slumped against the wet wall. Nine dead coins lay at his knees. His iron was spent, his worked stone spent, the live rock miles behind. He had a killing done and nothing left to kill again with. Then he heard it. Not water. A slow drag through the dark ahead, older and heavier than the beast. The floor shivered under his palms. "Something's coming," Merlyn said. His tattoos lay dark. "Bigger than the last." Kjell drew a knife. Beside him Thorgar set his feet, an axe in each hand. Thorin planted his father's axe and stared into the black. None of them spoke the plain fact. Steel would not hold whatever moved down there. Gunnar knelt and opened the stone-toned tome on his knees. Pillars of carved gold ran down its covers. Merlyn had read it with his own eyes for weeks now, sight bought with ten years of his life. "You've pulled from rock. From iron. From coins," Gunnar said. His blunt voice did not rise. "What haven't you pulled from?" Merlyn ran his fingers across the page. The border showed a sign he had skipped every time, ugly and forbidden. A blood-sign. It drew power straight from the carver's own body, no rock or iron between. His father had used it near the end. His father's hands had rotted from it. "I know that mark," Merlyn said. "It burns the one who cuts it." "Then don't," Thorin said, short and final. The drag grew louder. A cold, wet reek rolled up the tunnel. Merlyn felt the thing's weight through the stone, vast and patient. He had no other source. He had promised himself he would not die blind and bent like his father. He had not promised how much of the rest he would keep. "Give me the hammer," he told Gunnar. Gunnar looked at him a long moment. Then he pressed the twin-headed iron into Merlyn's grip. "How much will it take?" "Enough," Merlyn said. He dragged the hammer's edge across his own left forearm. Blood welled over the runic brands. He pressed the wet arm to the dead stone and cut the blood-sign with the hammer's point. Pain climbed his arm like fire up a fuse. His tattoos flared gold, brighter than they had all day, fed by his own body. The rune bit deep into the wall. The thing shrieked in the dark and stopped its dragging. The floor stilled. The reek pulled back down the tunnel and faded. Merlyn dropped the hammer. His left hand hung useless. The fingers would not close. He looked at Gunnar with the eyes he had paid so dearly to keep. "It held them off," he said. "But my hand's gone the way my father's went. If the next wall rises, I've only the one hand left to cut with."

The hum grew. It rose through the floor into Merlyn's knees, then his ruined arm, a slow beat like something vast turning in its sleep. He knew that feeling. His power sources were spent—rock, iron, coins, the lindworm scale, all dead behind him. He had one working hand and no fuel to carve a single sign. "It's coming for the sound," he said. "And I have nothing left to stop it." Kjell drew his throwing knives and set them on the stone. He had hunted trolls and draugr for a living, and he did not waste words. "Steel won't kill it," he said. "Not this deep." He looked at his old teacher. Merlyn had taught him to read runes years ago, in silence, for three hunts' worth of silver. Kjell knew what an empty rune-worker was worth in the dark. Nothing. "Then we don't kill it," Merlyn said. "We stop the hum. The sound woke it. Kill the sound, it goes back to sleep." Gunnar knelt with the stone-bound tome on his knees, its carved pillars catching the low light. He turned pages until Merlyn's fingers stopped him. "A silence-sign," Merlyn said. "It doesn't cut. It swallows. But it still needs power." "We have none," Gunnar said. Flat. Final. "We have the hum itself," Merlyn said. "It's power moving through the rock. I can carve a sign that drinks it. Turn the beast's own call against it." Thorin crouched by the wall, gray beard braided with iron, his father's axe across his knees. He pressed his palm to the floor and felt the beat. "Where do you cut," he asked. "The floor. Where the hum runs strongest." Merlyn dragged himself to the spot. His left hand hung useless. He set the hammer's point with his right, but he could not hold the stone steady and strike at once. Thorgar knelt and pinned Merlyn's wrist in one broad fist. "Go," he said. Merlyn struck. The sign bit into rock. The hum poured up through the floor and into the mark, and the mark pulled it in. His brands lit gold along his good arm. The vibration ran off the stone and vanished into the sign like water down a crack. He cut the second stroke, then the third. The hum thinned. Then it stopped. The tunnel fell dead quiet. Far below, the vast turning slowed and settled. Whatever had stirred sank back toward sleep. Merlyn slumped over the finished sign. It glowed faint, still drinking, holding the silence shut. "It's sleeping," he breathed. "The sound's gone." But his fingers found the mark's edge and traced it. The sign fed on the hum to stay lit. When the hum was fully spent, the sign would die—and the silence with it. He had bought quiet, not safety. "How long," Kjell asked. Merlyn pressed his ear to the stone. The faint pull was already weakening. "Not long," he said. "We move now, or we're here when it wakes hungry."

The silence-sign glowed at Merlyn's knee, but its light was already fading. He pressed his palm to it and felt the hum draining out fast. His good hand shook. His left hung dead at his side. He had no fuel to carve a path, and his weakened body could not walk far in the dark. "The sign holds for a few breaths more," he said. "We need a way out before it dies. I can't find one blind, and I can't stand for long." Kjell knelt beside his old teacher. Years back, Kjell had paid three hunts' worth of silver to learn runes from this man. He knew what Merlyn could do and what he could not. "You've got sight now," Kjell said. "Use it. Read the rock. Where's the air coming from?" Merlyn turned his face slow across the tunnel. His restored eyes stung in the dark, but they still worked. He caught a thin draft crossing his cheek. "There," he said, pointing left. "Air moves. A crack, low down. But my legs won't carry me." Thorgar bent and lifted Merlyn onto his broad back like a sack of grain. "Then I carry you," he said. He said it plain, the way he named ugly things and moved on. Gunnar went first, one thick hand on the wall, the tome strapped to his chest. Thorin followed with his father's axe, watching behind them for the beast. The silence-sign guttered out. The tunnel filled with a low, waking groan far below. "It's stirring," Merlyn breathed against Thorgar's shoulder. "The sign's dead." Gunnar stopped at the crack. It was a narrow slit in the rock, barely wide enough for a dwarf. Cold air poured through. "Tight," Gunnar said. "But it goes." Thorgar set Merlyn down at the gap. Merlyn ran his fingers over the stone edge and read it with his eyes close to the crack. The rock here was live. He felt the faint pull of earth power still humming in it. "This stone breathes," he said. "I can draw from it. Not to fight. Just to walk." He set the hammer's point against the live rock with his right hand. Thorgar pinned his wrist and held it steady. Merlyn cut a short conduit-sign, three strokes, drinking strength from the stone instead of his blood. His brands lit gold along his good arm. The ache left his legs. He stood on his own. Behind them, the groan grew into a grinding roar. "Go," Merlyn said. He pushed through the crack first, walking now, feeling the draft pull him toward open dark ahead. One by one they squeezed through. Thorgar came last and jammed his shoulder against the slit, packing it with loose rock. The roar was close now, but it could not follow through the narrow gap. Merlyn leaned on the far wall, breathing hard. He could walk. He could see. The beast was sealed behind them. But the live rock was already going cold under his hand, spent again.
