Rurik stood four feet three inches tall, and he had come to hire an army with nothing to pay it. His mountain hold sat under siege three valleys north. Every fighting man he called kin was trapped inside those walls. He had ridden out to raise a warband, and so far his warband was one dwarf and the iron-scaled wyrm coiled in the snow behind him. The beast was the size of a longboat. It did not count as a fighter. It could not hold a wall or swing a blade. The trading post crouched between the pines, its stone frontage lit by two iron lanterns. Rurik pushed through the studded door and stamped snow from his boots. Warmth hit him. The hearth hall glowed. Counters ran the length of the room, stacked with axes, gems, and coiled maps. Behind the largest counter sat the proprietor, a broad dwarf with a forked beard and a war-axe laid across his knees. He did not rise. He weighed Rurik with one flat glance and went back to polishing a blade. "You're the one whose hold is ringed," the proprietor said. "Word travels. So does the smart money. Nobody's buying that fight." "I'm not asking to buy," Rurik said. "I'm asking who'll stand with me." "Standing with you is a fast way to die poor." The proprietor set down his rag. "You've no coin, no men, and a hold that's already half a tomb. What have you got?" Rurik walked to the door and hauled it open. Cold poured in. The wyrm lifted its head from the snow. Its molten eye found the doorway. It hissed, low and long, and every lantern flame bent toward it. The proprietor stood. His axe came up an inch, then stopped. "That thing follows my word," Rurik said. "It clears trenches. It breaks gates. But it's one beast, and I'm one man. A siege needs bodies on the wall after the gate falls. You know these hills. Who's out here with nothing left to lose?" The proprietor stared at the wyrm a long moment. Then he laughed, short and rough. "With that," he said, "the mad ones might listen." He jerked his chin toward the trees. "Deeper in the woods there's a glade nobody sane enters. Wild folk live there. Elves, fae, beast-kin. They owe the valley lords nothing. And there's a stone-backed troll that lairs near them. It hates the men laying siege to you more than it hates the cold. Bring the wyrm. Bring your nerve. They'll hear you out." Rurik shut the door on the snow. He had walked in with one dwarf and a beast. He walked out with a name for his enemies and a place to find allies. But the glade did not answer to gold or to threats. And the troll that guarded its edge had killed the last three men who came asking for its help.

The proprietor's directions ended at a wall of thornvine. Rurik stood before it with the wyrm at his back and the dwarf beside him. The glade lay somewhere past this tangle, and the desperate folk in it were the only army he might raise. But the vines rose twice his height. Thorns as long as his fingers curved from every stem. Blue and pink fungi glowed between them. Deeper in, huge trees leaned together, their branches lit with strange light. No gap showed. A man who forced through would leave his blood on every barb. Rurik drew his hatchet and cut at the nearest vine. The stem snapped back and raked his forearm open. He cut again. The vines closed tighter, coiling where he had cleared. Behind him the wyrm hissed and lowered its head, ready to burn a path. Rurik lifted a hand to stop it. Fire would reach the trees. He would arrive at the glade having torched the home of the folk he meant to beg. A voice came from the trees to his left. "You'll bleed out before you're halfway." Rurik turned. A dark-haired man stepped from the pines, thick braids over layered furs, a weathered beard, one hand resting on an empty scabbard. He looked at the wyrm without flinching. He looked at Rurik's height and did not smile. "Who are you," Rurik said. It was not a question. It was a demand. "Bjorn. Six days I've watched three men die on those thorns." He nodded at the wall. "The vines answer to what's inside. Cut them, they cut back. Burn them, the trolls come." "You know a way through." "There's a beast that dens under the roots." Bjorn's voice stayed flat. "It carves tunnels beneath the thorns. I've watched it come and go. The wild folk let it pass. Follow its trail, the vines don't touch you." Rurik studied him. "Why tell me." "A blade of mine went into that glade on a thief's belt." Bjorn's jaw set. "I want it back. You want bodies for your wall. I'll take you through. You back my claim inside." Rurik weighed it a breath. His arm dripped onto the snow. "Show me the trail." Bjorn led him along the wall to a hollow at the base of an old trunk. The ground fell away into a low tunnel, smooth-walled, packed hard by something large that had passed many times. The thornvine hung above it, unbroken and quiet. Rurik knelt at the mouth and felt cold air breathe up from below. "It's in there now," Bjorn said. "We go when it leaves, or we go with it." Rurik sent the wyrm to guard the mouth. Then he crawled into the dark, Bjorn behind him. The thorns closed over the hollow. The way to the glade was open at last, and it ran straight beneath the den of the thing that had dug it.

The tunnel spat Rurik out into light. He stood, and Bjorn rose beside him. The glade opened wide. Glowing fungi lit the trunks. Vines climbed everywhere. Wild elves watched from the shadows. Beast-kin crouched in the moss. None moved. All of them looked past Rurik to the thing in the center. A troll blocked the heart of the glade. Its hide was bark and moss. Branches grew from its shoulders. It stood taller than three men and did not need to move to seem like a wall. It looked down at Rurik, at his four feet of height, and it laughed low. "Small king," the troll said. "You want their spears." It swept one heavy arm at the watching folk. "They follow strength. Show me yours, or crawl back to your hole." Rurik did not reach for his hatchet. He had left the wyrm at the tunnel mouth. He had nothing here but two men and his own two hands. Behind him a voice spoke, low and flat. "Don't fight it," Thorin said. The old dwarf climbed out of the tunnel last, his father's axe across his back. Gray beard, iron rings, a battered helmet. He had followed Rurik through the dark without complaint, the way he had followed him from the pass. His knees popped as he stood. He looked at the troll the way a man looks at weather. "It wants us broken," Thorin said. "Strength isn't lifting it." Rurik understood. The troll wanted a fool to swing first. He would not. He stepped forward instead. He walked until he stood in the troll's shadow and had to bend his neck to hold its eyes. The wild folk leaned in. "An army burned my supply road," Rurik said. "They killed a man who served that pass forty years. I came here begging. That's not weak. That's what a chief does when his people are dying." He set his boots wide. "Move, or don't. But I'm not crawling back." The troll studied him a long while. Then it reached down. Rurik held still. The huge hand did not strike. It pressed flat against Rurik's chest, testing, the way a man tests a beam before he trusts it. Rurik did not step back. His heels held. "Stone," the troll said at last. It drew its hand away. "You don't bend. Good." It stepped aside. The path to the glade's heart lay open. The wild folk rose from the moss, watching now with new eyes. Then Bjorn spoke. "My blade came in on a thief's belt." His hand found his empty scabbard. "I want it back before any bargain." At his words a fae figure stiffened across the clearing. A wild elf reached for a bow. The moss went tense. Rurik had won his way in. Now Bjorn's claim split the very folk Rurik had come to gather, and every eye turned cold.

Bjorn's words hung in the glade. The wild folk had risen for Rurik moments ago. Now they turned on each other. A wild elf with blood-red eyes stepped forward from the beast-kin. She wore green cloth and feathers, and a red mark stained one cheek. Her hand rested on a curved blade at her hip. She was the thief Bjorn meant, and every elf behind her drew close, ready to bleed for her. "He calls us thieves," the red-eyed elf said. Her voice carried. "He crawls into our home and names us dogs." A fae figure hissed. Bows lifted. The alliance Rurik had won was cracking in front of him. Rurik stepped between them. He had to crane his neck to hold Bjorn's eyes, then turn to face the elf. "Bjorn." His voice was flat. "The blade waits. My people don't." Bjorn's hand stayed on his empty scabbard. He did not move. Thorin came up beside Rurik. The old dwarf looked at the drawn bows and said nothing at first. Then he spoke low, for Rurik alone. "He'll get us all killed over a sword. Or you fix it now." Rurik knew Thorin was right. He turned to the red-eyed elf. "Did you take his blade?" She met his eyes. "I took it off a raider two winters past. He came burning. I burned back." She drew the curved blade and held it flat. "It was never Bjorn's." Bjorn stared at the blade. His jaw worked. "That's my clan's steel. Six generations." "Then your clan's steel was in a thief's hand before it was in mine," the elf said. "I killed the thief. That makes it mine." The glade went still. Bjorn could swing, and the elves would answer, and Rurik's army would die here in the moss. Rurik saw it clear. He made his choice. "Bjorn." Rurik stepped close. "You want the blade back. She wants blood paid for it. Both true." He put his hand on Bjorn's arm. "Ride with me. Break my siege. When it's done, I'll buy that blade off her with the raider's gold we take. You get your steel. She gets her due. Nobody dies in this glade." Bjorn looked at the elf a long time. He looked at the empty scabbard. Then he closed his hand and let it fall from the hilt. "After the siege," he said. "Your word." "My word," Rurik said. The elf slid the blade back into her belt. The bows lowered. The fae eased into the moss. Rurik breathed. The quarrel was done, and the wild folk were still one. The red-eyed elf stepped closer to Rurik. "You held the fight off," she said. "But I don't march for a stranger's word. Show us this army you want us to bleed for." Behind her, the beast-kin and fae watched, waiting. Rurik had kept the alliance. Now he had to prove the siege was worth their spears.

The wild folk followed Rurik out of the glade to see his army. His wyrm waited by the tunnel, iron scales dark in the light, its eye burning amber. But the red-eyed elf had asked for proof the siege was worth their spears. Rurik had shown her the wyrm. Now Bjorn wanted his proof too. He fell into step beside Rurik on the trail down. "The gold," Bjorn said. "You promised raider's gold for the blade. Show me it exists." Rurik kept walking. "After the siege. I take their war chest. You get paid." "Words." Bjorn stopped. The wild folk behind them stopped too. "My uncle died over words. I don't ride on them." He put his hand near his empty scabbard. "Show me the gold now, or I take my men and go." Rurik had no gold. The gold sat in an enemy camp he had not yet beaten. He felt the whole alliance tip on Bjorn's next step. Thorin came up on his other side, ax loose in his fist, watching Bjorn the way a man watches a snapped rope. "He can't show you what he hasn't taken," Thorin said. "Nobody can." "Then his word's worth nothing." Bjorn turned to leave. Rurik grabbed his arm. "You want steel you can hold. Fine." He reached to his own belt and unbuckled it. His father's axe was in the gate post at Greyspine, but this belt-knife had ridden with him since he claimed the pass. The handle was wrapped in old wire. He pressed it into Bjorn's hand. "This stays with you until the gold's in your fist. It's worth more to me than the sword you're chasing. If I don't pay, you keep it and take my hand with it." Bjorn looked at the knife. He turned it over. The wire was worn smooth where Rurik gripped it. "A knife's not gold," Bjorn said. "It's a hostage," Thorin said. "Same thing men have traded for a thousand years. He gives you the thing he won't leave behind. That's how you know he'll come back for it." Bjorn closed his hand on the knife. He was quiet a long moment. Then he slid it into his belt, next to the empty scabbard. "Until the gold," he said. "Then I trade it back for the blade." "Until the gold," Rurik said. The wild folk watched the two men clasp arms. Bjorn's loyalty held, bought now with iron instead of a promise. But Rurik felt the weight of it settle. He had staked his father's knife on gold that sat inside the enemy's camp. To keep his word to Bjorn, he had to break the siege first. And the war chest he had promised was ringed by the very army besieging his home.

The alliance was bought. Now Rurik had to use it. He led his warband down toward Greyspine and stopped where the trees still hid them from the plain. Below, the enemy camp ringed his hold. He could see tents and cook-fires, but not the lines that mattered. Where were the watches? Where were the weak points? March in blind, and he'd feed his people to a wall of spears. Thorin crouched beside him and spat. "Can't fight what you can't see." "Then we see first," Rurik said. "We send a scout close. Count the pickets. Find the gap." Bjorn shook his head. "They'll take a man who walks that ground. He won't walk back." Rurik knew he was right. A man on foot would die on the open plain. He needed eyes that moved faster than a spear could reach. Brenna came up the slope behind them. Rurik had met her three days past, a dwarf shield maiden racing south ahead of the freeze. Her eldest brother's shield hung on her back, and she'd sworn to reach Greyspine before the passes closed. She dropped to a knee beside Rurik and looked at the camp the way a smith looks at a bad weld. "Your enemy's lazy," she said. "They've bunched the tents on the near side. The far slope's near empty." "You can't know that from here," Bjorn said. "I watched their smoke this morning. Cook-fires cluster where the men sleep." She pointed. "Nobody's cooking on the north edge. That's your gap." Rurik studied where she pointed. It could be a gap. It could be a trap. He would not stake the warband on smoke. "I want proof before I move." "Then let me prove it." Rurik whistled low. The wyrm slid from the trees, iron scales dark, its eye burning amber. Rurik pointed it toward the camp. It climbed the air in a long slow circle, high enough that the men below shielded their eyes and never raised a bow. It crossed the whole ring once, then dropped back into the trees and coiled at his feet. Rurik had walked it before. He knew how it turned when it saw men, how it slowed where it saw none. He read its path in his head. "It banked over the near tents. It flew straight over the north slope. No men there." He looked at Brenna. "You were right. The north edge is open." Brenna nodded once. "Told you." Bjorn grunted. "Then that's where we hit them." Rurik stood. He had the enemy's shape now, drawn plain in his mind. He knew where the spears were thick and where the ground lay bare. "We march at dark. We come through the north slope and roll their line before they wake." The blind march was gone. But knowing the gap meant using it, and a night attack on a sleeping camp could wake into a battle he could not stop.

The north slope was open. Rurik had proof of that. But when his wyrm circled back a second time, it slowed over two dead trees on the ridge. Rurik read the pause. He crept forward through the brush and looked. Two ravens sat on the bare branches. They wore worked leather bands on their legs, cut with old knotwork. These were not wild birds. The enemy had posted them as watchers. One raven would fly at the first boot on the slope, and the whole camp would wake before an axe fell. "Watchbirds," Thorin said beside him. He spat. "You can't rush past those." Brenna crouched low and studied the trees. She had scouted this camp with her eyes for days, and now she read the birds the same way. "Two of them. Wide apart. One bow can't drop both before the other lifts." She shook her head. "We shoot one, the other screams." Bjorn said nothing. He knelt and watched the ravens, hard-eyed. Rurik knew he was counting the same odds and finding none. Rurik looked at the wyrm coiled at his feet. It had flown over the birds twice and they had not moved. They knew it. They did not fear a thing that circled and left. "They ignore the wyrm," he said. "They've seen it all night." "So?" Thorin asked. "So it doesn't spook them. It can get close." Rurik set his hand on the iron scales. "Fast, both at once, before either takes air." Bjorn's head turned. "One beast. Two birds." "One pass," Rurik said. "It takes one in the jaws and one in the claws." He had walked the wyrm a hundred times. He knew how it struck. He knew it could take two men in a single lunge. Two ravens were smaller game. Brenna held his eyes. "And if it misses one." "Then the camp wakes and we're dead on the slope." Rurik did not soften it. "But we're dead on the slope either way if I do nothing." He pointed the wyrm at the ridge and gave the low whistle. The beast slid off through the dark, belly to the ground, the way it had never flown before them. It went slow. The ravens watched it come and stayed still, because it had come and gone all night. At the last stride the wyrm rose. Its jaws closed on the near bird. Its claws snapped shut on the far one. Both went down without a cry. No wings hit the air. No sound reached the tents below. Rurik let out his breath. The watchers were dead. The slope lay open and blind. "Now," he said, and stood. "Before they post new ones." Bjorn was already moving. Brenna set her shield. Thorin drew his father's axe. The gap was theirs, and the count against them had just begun.

Both watchbirds lay dead on the ridge. Rurik stood and started for the slope. Then he heard it. A thin, high whine, steady under the wind. One raven still moved. Its wing dragged. Its leg band caught the last of the moonlight, and the knotwork glowed faint blue. A warning-charm. It had not screamed, but it did not need to. The charm carried its own voice. If that sound reached the tents below, the camp would wake before Rurik crossed the open ground. "The band," Brenna said. She dropped to a knee beside the bird. Her hand hovered over it. "It's singing. I've seen this. Break the bird, you don't break the charm." She had scouted this camp for days and read every fire in it. Now she read the sound and shook her head. "Cut the leg. Fast. But the cut carries too." Thorin crouched over the raven. He said nothing for a moment. The old dwarf had walked out of one betrayed pass alone, and he weighed every plan like it might be the one that killed him. "Bury the sound," he said. "Not the bird." Rurik understood. He looked at the wyrm. "Under it," he said. "Whole beast on top." He gave the low whistle and pointed at the twitching raven. Bjorn caught his arm. The man had ridden here on Rurik's promise and a knife given in trust, and he trusted nothing he could not see done. "One beast makes noise too," he said. "Its scales on stone." "Then we cover the scales with dirt," Rurik said. He knelt and dug with both hands into the soft ground under the dead tree. Brenna dug beside him. Thorin scraped a trench with his axe blade. The whine climbed. Rurik felt it in his teeth. The wyrm settled its bulk over the raven and pressed it into the hole. Rurik shoved the loose earth up against its flank. Brenna packed it hard with her shield. Bjorn dropped his cloak over the last gap and stamped it flat. The whine dropped to nothing. Rurik held his breath and listened past the wind. No horn. No shout from the tents. The charm sang into dirt and beast and heard no answer back. "Down," Rurik whispered. "Slow." They moved off the ridge. But Bjorn stopped at the tree line and pointed his chin at the sky. Above the far end of the camp, a third dark shape circled. Wide bands on both legs. Another watchbird, already up, already turning toward the north slope they had just opened. "They keep a spare," Brenna said. Rurik looked at his wyrm, half-buried and slow to rise. The blind gap was theirs. But the enemy still had one eye in the air, and now it was flying home.

The third watchbird cut north across the sky. Rurik watched it come and felt the ground close around him. His wyrm lay half-buried at the ridge, slow and out of the fight. Below, the enemy camp slept behind sparse cook-fires. If the bird's leg band screamed over those tents, every plan died here. He had killed two ravens in silence. He could not kill this one in time. "It's already turned," Brenna said. She rose from the packed dirt, shield on her arm. The dwarf shield maiden had read every fire in that camp to find the weak slope. Now she read the bird's line and her jaw set. "It saw the wyrm move. It knows something's wrong." Bjorn stood at the tree line. He had ridden here on Rurik's word and a knife given in trust, and he trusted nothing he could not see done. "Then we're finished," he said. He did not soften it. Thorin crouched by the muffled raven. The old dwarf had walked out of one betrayed pass alone. He weighed each plan like it might kill him. He looked at the dead bird under the dirt, then up at the live one closing in. "Same trick," he said. "Different hand." Rurik understood. The wyrm was spent. But the second raven was not fully buried. He dug it free with both hands, the leg band still warm and silent under packed earth. He pulled a coin from his belt pouch, one of the stamped Viking pieces meant to pay Bjorn's debt after the siege. He tied the coin to the dead bird's leg with a strip of leather. "They come to their own," he whispered. "Give it something to land on." He threw the dead raven high off the ridge. It spun out over the open slope, the coin catching moonlight like a live eye. The third watchbird broke its northward line and dropped toward the falling shape. It circled once, low, hunting the glint. "Now," Rurik said, and gave the low whistle. The wyrm tore free of the dirt. It rose in one hard beat and struck the circling bird from below. Feathers burst. The watchbird folded and dropped. Brenna was already running. She met it where it fell and drove her shield rim down on the leg band. The whine started, thin and blue. She ground it into the stone under her weight until it died. Silence held. No horn. No shout from the tents. Rurik stood over the two dead birds. The enemy had no more eyes in the air. The north slope lay open and blind. But he looked at the coin in the dirt, cut loose and dented flat, and knew the pouch that paid Bjorn was one piece lighter now. Bjorn saw it too. He said nothing. He only touched the empty sheath where his knife had been, and turned toward the dark camp below.

The birds were dead and the slope lay open. Rurik crouched at the ridge and looked down at the sleeping camp. His warband waited behind him in the trees, scattered along the tree line. That was the trouble. Bjorn's men held one edge. Thorin held the center. The wild folk waited apart, watching, still unsure. If Rurik gave the word, each cluster would break loose at its own pace. A ragged line would spill down the slope in pieces, and the enemy would cut them apart one group at a time. "They'll charge when they see me move," Rurik said. "Not together. Scattered." Thorin knelt beside him. The old dwarf had walked out of one betrayed pass alone, and he weighed every plan like it might be his last. He looked at the tree line, then at the men strung along it. "Too many hands," he said. "They need one signal. One start." Bjorn stood behind them, arms crossed. He had ridden here on Rurik's word and a knife given in trust. "A horn," he said. "Wakes the camp too. Same as a scream." He was right. A horn would carry to every tent. Rurik pressed his fist to the cold stone. His wyrm lay curled below the ridge, spent and slow, iron scales dull in the moonlight. It could not fly. But it did not need to fly. Rurik went to it and put his hand flat on its neck. The beast lifted its head. Its one good eye caught the light like an ember. "Not a sound they hear," Rurik said. "A sound only we know." He had trained the wyrm on a low call across the glade nights. A single note, thrown up from the throat, felt more than heard. It rolled through the ground, not the air. His own men had learned to feel it in their boots. The enemy in their tents would feel nothing. "When it hums," Rurik told Thorin, "you go. All of you. One breath, one line." Thorin passed the word down the tree line, dwarf to man to wild folk, hand on shoulder, no voices. Rurik watched each cluster nod. Bjorn drew his axe and set his feet. Even the wild folk shifted forward, ready as one shape now. Rurik put his hand back on the wyrm and gave the sign. The beast opened its throat. No shriek came out. A deep note rolled through the stone, up through every boot on the ridge. Rurik felt it in his teeth. The whole line broke at once. Not clusters. One wall of shields and axes poured down the open slope together, silent until the first blade struck a tent rope. The warband hit the north edge as a single fist. The camp woke to a wall already on top of it. Rurik ran at the center, his father's blood in his arms, and for the first time the siege bent under his weight.

The camp was theirs, all but one thing. In the middle of the burning tents rose a squat stone tower. Rurik's men crashed against its door and fell back. Arrows came from the slits above, quick and sure. Two of the wild folk lay dead in the open mud. Every man who ran at the door drew fire. Rurik crouched behind an overturned cart and watched the shafts fall. Thorin dropped beside him, breathing hard. The old dwarf had fought his way through the center and still gripped his father's axe. "Door's oak banded with iron," he said. "We won't cut it. Not before they cut us." "Then we don't cut it," Rurik said. He looked at the tower slits, then at his wyrm. The beast lay near the wall, too spent to fly. But it could still crawl, and its iron scales could still turn an arrow. Bjorn came at a low run and threw himself down. Blood ran from a cut on his arm. He had ridden here on Rurik's word and a knife given as hostage. "They'll hold that stone till dawn," he said. "Then their main host wakes and takes us from behind." Rurik had no time and no gold to buy any. He turned to the ones still with him. Kjell knelt near the cart, a monster hunter with teeth strung in his beard, iron traps hung at his belt. Beside him stood Gunnar, the smith, broad through the shoulders, a heavy hammer in his fist. "The door," Rurik said to Gunnar. "You know iron. Where does it fail?" Gunnar wiped soot from his eyes. "Hinges," he said. "Not the wood. The pins." Rurik moved fast. He sent the wyrm forward first, crawling low, its scaled back raised like a shield against the slits above. Arrows struck the beast and skidded off. Behind it came Rurik, Thorin, Gunnar, and Bjorn, crouched in its shadow. Kjell hung back and threw. His silver-tipped knives found the slits, and two archers dropped their bows to duck. At the door Gunnar swung. The hammer rang once, twice, on the lower hinge pin. Iron screamed. The pin bent, then jumped free. He struck the upper pin while Rurik and Thorin set their shoulders to the wood. Bjorn braced beside them. The last pin sheared. The whole door tore loose and fell inward with a crash. Men poured through the gap. The archers had no time to draw. It was close work now, axe and knife in a small stone room, and close work was where Rurik's people were strongest. In moments the tower fell silent. Rurik stood in the dark room, breathing smoke. The north camp was broken and the tower was his. But through the arrow slit he saw torches waking to the south. The enemy's main host had heard the tower fall, and now it was rising.

The tower was silent now, but the south was waking. Rurik counted torches on the far slope and knew the enemy's main host would march at dawn. He would meet it blind unless he learned how it planned to come. Then Thorin dragged a man up from the tower's lower room. An officer, hands bound, a captain's badge on his chest. "He was giving the orders," Thorin said. "He knows the plan." Rurik crouched to meet the man's eyes. "Your host wakes," he said. "How does it march? Where does it strike first?" The officer spat blood on the stone and said nothing. Rurik asked again, slower. Still nothing. The man had the calm of someone who knew Rurik could not spare a torturer's hour with the host so close. "We'll get nothing this way," Rurik said. Bjorn stood at the door, blood drying on his arm. He had ridden here on Rurik's word and a hostage knife. "Then kill him," Bjorn said. "He costs us food." Kjell came in from the yard, teeth strung in his beard, iron traps at his belt. He looked at the officer the way he looked at things he had tracked. "He's afraid," Kjell said. "Not of dying. Of something else." Rurik followed the man's eyes. They kept drifting to a table by the wall. On it lay a stack of stamped coins, a war chest's tally, and a scatter of dispatches. Beside the coins rested a moth pinned under glass, its wings dusted gray, its edges glowing like banked coals. A courier's seal. Rurik lifted the coins. The officer's jaw tightened. "These aren't yours," Rurik said. He turned a coin in the firelight. "You skimmed the war chest. Your commander doesn't know." He set the coins down slowly. "I ride south at dawn. If I fall, your commander finds this room. He finds the count short. He finds you took the tower's silver." He let it sit. "Or you tell me how the host marches, and these coins ride out with me. No count. No proof." The officer stared at the coins a long moment. Then he broke. "They come up the ravine, not the open slope," he said. "Two wings. The heavy foot holds the center to pin you. The riders swing wide and take your flank." He gave the timing, the signal horn, the reserve held back. Kjell watched his face and gave Rurik a small nod. Truth. Rurik stood. He knew the shape of the fight now. The ravine, the flanking riders, the pinning center. He could set his own trap in the ground before dawn. "Bind him tighter," he told Thorin. He pocketed the coins. But the plan he'd bought only made the danger plain. The host was larger than his warband, and it would be on him by first light. Blind no longer, he now had to survive what he'd finally learned to see.

Rurik pocketed the coins and stepped into the yard. The captured camp lay quiet around him. His men sat where they had fallen when the fighting stopped. Some slept. Some stared at nothing. They had taken the camp and the tower, but the night had emptied them. The southern host would come up the ravine at dawn, and these hands could barely hold their axes. Thorin found him counting the sleepers. The old dwarf's chainmail hung heavy, his knees stiff from the long night. He said what Rurik already knew. "They can't fight like this. Half will die before the riders reach the flank." "Then we don't fight tired," Rurik said. He looked past the tents. The enemy had built a brewing hall on the high ground, stone-walled, its chimney cold. Barrels lined the front. Inside waited what an army stores for the night before a march: mead, bread, salt meat. "Their stores are ours now. Feed the men. Two hours' sleep in shifts. Half rest, half watch." Gunnar came from the hall already, soot on his hands, a mead cask under one thick arm. He set it down hard. "Full," he said. "Grain sacks in back. Enough for all of us." He pried the cask lid loose with his hammer. "They meant to drink after they killed you." Kjell moved through the camp like he tracked something. He kicked sleepers awake, pointed them to the hall, sent them back to their posts. "Eat standing," he told them. "You sleep when I say." He turned to Rurik. "Wyrm's spent too. It hasn't fed since the birds." The iron-scaled wyrm lay coiled against the tower wall, its serpent body dull, one gold eye half open. Rurik knelt and pressed a hand to its cold scales. He had leaned on it all night, for the doors, for the signal, for the birds. He could not spend it dry. "Meat," he told Kjell. "Whatever they salted. Let it eat and rest." Bjorn watched from the hall door, blood dried on his arm. He had ridden here on a promised sword and a hostage knife, and he trusted little. "You feed them and they'll sleep too deep," he said. "The host won't wait for us to wake." "Two hours," Rurik said. "Then they'll stand." He held Bjorn's stare. "Fed men hold a line. Starved ones break." Bjorn looked at the sleeping warband, then at the mead. He said nothing more, which from him was agreement. The warband ate in shifts. They drank one cup each, no more, and Kjell counted the pours. Men closed their eyes against the stone and the wyrm drew warmth back into its blood. When Rurik walked the line again, the sleepers woke faster. Hands gripped harder. The exhaustion had not left them, but they could fight. He climbed the tower and looked south. Torches moved in the dark, forming into wings. The host was marching early. His men were fed and standing, but the enemy would reach the ravine before the two hours ended.

Rurik came down from the tower with the enemy plan clear in his head. The riders would sweep the ravine at dawn, cavalry on both wings, the center pinning his line. He knew where they would come. He had no way to stop the horses once they entered. A ravine with open ends was a road, not a trap. He needed a wall. He gathered the others in the yard. Thorin, the old dwarf who had walked at his shoulder all night, leaned on his rune-carved axe. Bjorn stood apart, blood dried on his arm, still weighing every word Rurik spoke. Gunnar wiped soot from his hands. Kjell watched the south, where torches formed into wings. "Cavalry needs open ground," Rurik said. "We give them none. We close the ravine mouth. Funnel the wings into one narrow throat, then hold it." "With what?" Bjorn said. "We have no wall." Rurik pointed at the brewing hall on the high ground. Barrels lined its front, stacked two deep. "We have those. Full casks, grain sacks, the tower's fallen doors. We build across the ravine mouth before the sun." Thorin frowned. "Barrels won't stop a horse at the gallop." "They'll slow it. Break its legs." Rurik turned to Gunnar. "You breached the tower. Can you drop the iron doors across the gap?" Gunnar looked at the ravine, then the hall. "Doors, casks, a wagon on its side. Lash it. Won't be pretty." He hefted his hammer. "It'll hold long enough to kill on." They worked in the dark. Kjell drove the men in shifts, the way he had at the mead hall. They rolled the full casks down and wedged them mouth to mouth. Gunnar and two others dragged the iron-banded doors from the tower and set them upright, braced with grain sacks. Bjorn heaved a supply wagon onto its side and jammed it into the throat. Rurik brought the wyrm last. The iron-scaled body had drawn back its warmth from the meat and the rest. He walked it into the narrow gap and coiled it low behind the wall, gold eye open. "You wait here," he told it. "When they pile against the barrels, you come over the top." Gunnar drove the final spike as the sky went gray. He stepped back and spat. "Done." The wall crossed the ravine mouth, waist-high, ugly, packed tight. The wide road had become a throat one horse wide. Rurik set his archers on the high sides and his line behind the barrels. Then the ground shook with hooves. The southern host came up the ravine at the gallop, both wings pouring toward the open mouth. The lead horses hit the wall of casks and doors. Legs snapped. Riders pitched forward into the packed throat, and the horses behind crushed into the wreck. The killing ground was made. But the center column did not charge the wall. It split left and climbed the ravine's stone side, coming for the archers on the high ground.

The center column climbed the ravine's stone side. Rurik watched from behind the barrel wall as enemy foot soldiers spilled over the high edge and fell on his archers. His trap had worked on the horses. Now it was failing on the men. He killed one rider pinned against the casks, then turned and saw why the attack would not stop. A man stood on the ravine's rim, tall in a red cloak, pointing with a sword. He waved fresh soldiers up the slope in waves. Every time Rurik's line pushed back, the man in red sent more. The enemy commander was steering the whole fight from above. Rurik grabbed Thorin's arm. The old dwarf had walked at his shoulder all night, blunt and steady, his father's rune-carved axe wet to the haft. "See him? The one directing." Thorin followed his eyes. "Kill him. The waves stop." "They stop," Rurik said. "I can't reach him. The slope's crawling." "Then don't climb it." Thorin nodded at the barrier's low end, where the ground fell away into the ravine. "Send the worm." Rurik looked at the wyrm coiled behind the wall. Its iron scales ran with blood from the trapped horses. Its gold eye tracked him. He had held it back for the killing throat. But the throat was won, and the rim was losing. He put his hand flat on the cold scales. "Up," he said. "The man in red." The wyrm poured out of the ravine like water running backward. It went up the stone face where no horse could climb, silent, fast. Bjorn saw it go. He wrenched his axe from a fallen man and shouted to the archers, plain and hard: "Cover it! Loose high!" Arrows raked the rim. Kjell threw a silver-tipped knife that took a soldier through the throat before the man could turn. Gunnar heaved a broken door aside and drove three enemy back with his hammer, clearing the wyrm's path. The commander saw the wyrm too late. He swung his sword at the great head. The blade skated off the iron scales. The wyrm struck once and took him off the rim. He fell into the ravine and did not rise. The waves broke. Without the man in red pointing, the soldiers on the slope stopped climbing. They looked to a rim that gave no orders. Rurik climbed onto a cask and roared for his line to push. His warband surged up the stone, and the enemy foot began to run. Thorin wiped his axe and spat. "Told you." Rurik did not answer. He watched the enemy break and scatter down the far side of the ravine. The dawn assault was finished. But he counted his archers on the high ground and found gaps where men had stood. The wyrm came down slow, dragging one wing of its body, a fresh gash open along its flank. The southern host was broken. His weapon was hurt, and the siege was not yet lifted.

The last enemy foot soldier vanished down the far side of the ravine. Rurik walked his line and counted. Where twenty archers had stood at dusk, eleven remained. The wounded he could carry. The dead he could not. His wyrm lay coiled below the barrel wall, one wing of its body dragging, the fresh gash black along its iron scales. The dawn assault was broken. But Rurik knew what broke assaults did next. They rallied, counted their own gaps, and came back at the thin place. His thin place was here, on this ground, with eleven bows. Thorin climbed onto a cask beside him and looked south. "They'll re-form. Down past the tree line." "How long?" "An hour. Maybe less." Thorin wiped his father's axe on a dead man's cloak. "You can't hold the rim with eleven bows." Rurik did not answer. He looked at the ravine walls, at the makeshift barrier of casks and grain sacks and iron doors his men had built through the night. The trap had killed the horses. It could kill again, if the enemy did not learn. Bjorn came up the slope, blood dried on his beard, dragging an armful of enemy shields. He dropped them in the dirt. "Their bows. Off the dead." He kicked a bundle of enemy quivers toward Rurik. "Take what they carried." Rurik understood. "Arm the men who can't draw. Line them on the rim. Make it look full." "Won't fool a man who counts," Bjorn said. "They won't count. They'll see a full rim and a live wyrm." Rurik turned to Gunnar, who was already prying an iron door loose from the wall. "The barrier. Can you move it up?" "Break my back doing it," Gunnar said. He hefted the door onto his shoulder. "But yes. Narrow the mouth. They come in single, they die single." Kjell walked the ravine floor below, setting his iron traps in the churned mud where the horses had fallen. He looked up once. "Anything that steps here loses a foot. That buys a breath." Rurik put his hand on the wyrm's cold scales. The gold eye rolled toward him. He could not send it up the wall again. It could barely climb. But it could still coil behind the narrowed gap and strike what came through. "One more," he told it. "Just hold the mouth." They worked the hour Thorin gave them. Gunnar hauled the doors up and pinned the ravine to a gap two men wide. Kjell seeded the mud with iron. Bjorn stood dead men's bows in the hands of the wounded. When the enemy re-formed and marched, they saw a full rim, a live wyrm, and a gap that swallowed men one at a time. They tested it once. Three men stepped into the traps and fell. The wyrm took the first through. The others pulled back and did not come again. The pass held. Rurik had eleven bows and a wounded wyrm, and it was enough for today. But the enemy had not fled. They had only stopped counting.

The pass held. But the enemy did not leave. They pulled back past the tree line and stopped, out of sight. Rurik stood at the narrowed gap and watched the empty ground. Silence was worse than the charge. He could not tell if they meant to march home or circle wide and strike his blind side. Eleven bows could not guard two directions at once. "They're doing something down there," Rurik said. "I can't see what." Thorin climbed the cask beside him. The old dwarf carried his father's axe, its runes cut deep in the steel. He had walked out of one betrayed pass alone; he knew the shape of men planning a second blow. "Could be a retreat," Thorin said. "Could be they're splitting to come around. You wait to find out, you find out too late." "Then I stop waiting." Rurik turned to the wyrm. It lay coiled below the barrel wall, the black gash still wet along its iron scales. Its gold eye rolled to him. He knew he asked too much. It could not climb the wall again. But it could still fly, if only for a moment. "One pass," Rurik told it. "Look. Then come back." Bjorn caught his arm. The dark-braided warrior had bargained safe passage for a stolen blade, and held Rurik's own belt-knife as hostage against the gold still owed. He did not waste words. "It's hurt. Send it up, it may not come down." "If they circle, we're all dead by dusk," Rurik said. "I need eyes." Bjorn let go. "Your creature. Your call." Rurik put his hand flat on the cold scales. The wyrm gathered itself, uncoiled, and rose off the ravine floor. One side of its body dragged. It climbed slow, wobbling, over the tree line, and vanished south. Kjell watched it go from below, a hand on his traps. "If it drops, I can't reach it," the hunter said. "Not before they do." Rurik counted his own breaths. Twenty. Forty. Then the wyrm came back over the trees, low and crooked, and folded down behind the wall. It hummed. The sound came up through the dirt, a deep vibration in Rurik's boots. He had trained his men to know it. One pulse, then two. "Two," Thorin said. "That's the split signal." "They're not retreating." Rurik felt the truth settle in his gut. "They're coming wide. West side, past the rim." He looked at the eleven exhausted bows, at Gunnar leaning on a pried iron door, at the traps seeded in mud that guarded only the mouth. The blind blow had a direction now. It had a direction, and it was coming for the one flank he had left open. Rurik pulled his men off the narrowed gap. "Leave the mouth to the traps," he said. "We swing west. We meet them before they crest the rim."

Rurik led his men west along the rim. The wyrm dragged behind them, one side stiff with its wound. He saw the flanking force below, cresting the slope for the west side. They moved fast. His men were spent, their arms heavy from a night and a dawn of fighting. If the enemy reached the open ground first, they would spread wide and charge. Eleven tired bows could not stop a charge on flat rock. "We won't beat them to the top," Thorin said. The old dwarf climbed slower than the rest now, his knees stiff under worn mail. He carried his father's axe across his back, the protection runes worn shiny by his thumb. He had walked out of one betrayed pass alone; he read ground the way other men read faces. "Open ground gives them the horses. We need a throat to choke them in." Rurik looked at the rim. He saw a narrow cut where the rock pinched, just below the crest. "There," he said. "They have to funnel through that gap. One at a time." Gunnar dropped the iron door he had carried since the ravine. The blacksmith's hands were black with soot and old blood. "Metal's tired," he said, kicking the door flat across the cut. "So am I. It'll hold once." Kjell was already on his knees in the mud past the gap. He worked fast, setting his iron traps in the dark between stones. "Five," the hunter said. "That's all I have left." He set the last jaw and stood. "Anything through the gap loses a foot." Bjorn planted himself at the mouth of the cut. He drew his axe and said nothing. Rurik's belt-knife still hung at Bjorn's hip, held as hostage against gold not yet paid. Bjorn had followed him this far without the coin. He would fight the flank first and settle debts after. The enemy hit the gap. The lead horses took the traps and screamed. Bodies piled in the narrow cut. Behind the iron door, the eleven bows loosed into the crush. Gunnar's door buckled but held. Bjorn's axe rose and fell at the mouth. The wyrm pressed low behind them and let out its subsonic hum, and Rurik's men held the line as one. The flank broke. The enemy could not spread. They could not charge. They died in the throat of the cut or turned and ran back down the slope. Rurik stood in the gap and watched them go. Then Kjell called from the rock above. "North." He pointed past the crest, off the west side entirely. "Riders. A fresh column. No banners." Rurik climbed to see. A second body of horses crossed the far ground, moving hard for the pass itself while both his horses bled here. He had beaten the flank. He had spent everything to do it. And the road home stood open behind him.

Rurik came down off the rock. The fresh column crossed the far ground, hard for the pass. Both his wyrms bled here in the cut. His men leaned on their bows and could barely stand. Eleven arrows would not turn horses. He counted the hands he had and knew the number was too small. He needed more before that column reached the throat of the pass. "We can't hold two fronts," Thorin said. The old dwarf wiped his father's axe on his sleeve. "Not with this many. Not tired." "Then we find more hands," Rurik said. Bjorn spat blood into the mud. "There are none. We spent them all." Rurik's belt-knife still hung at Bjorn's hip, the hostage against gold not yet paid. Bjorn met his eyes and did not look away. "The wild folk stayed back. They wanted proof." Rurik looked north, past the crest, toward the low ground where the stone brewing hall sat. He had passed it going in. Kjell's group had gone that way at dusk, into the enemy camp, hunting the master under the mountain. If any of them lived, they were close. "Kjell," Rurik said. "Send the wyrm." Gunnar frowned. "It's cut half through." "It can fly once more." Rurik knelt by the wounded creature and pressed his hand to its neck. "Find the hunter. Bring him." The wyrm dragged itself up and beat into the sky, listing on the torn side. They waited in the cut. The column grew larger on the far ground. Then boots came up the slope, and Rurik reached for his axe. Kjell climbed into the gap first. His braided beard was short one troll tooth, the space raw where it had ridden thirty years. Blood crusted his armor. Behind him came men Rurik had not sent out and did not know, hard mountain fighters with soot on their hands and enemy weapons in their fists. A dozen of them, then more. "The master under the mountain is dead," Kjell said. He did not soften it. "We opened the deep roads and killed what sat there." He looked at the column across the ground. "These freed themselves when the binding broke. Their homes are gone. They'll fight the ones who burned them." Rurik counted. Thirty hands, maybe forty. Fresh. Angry. "They fight for pay?" Bjorn asked. "They fight for the men who torched their fields," Kjell said. "That's the ones coming now." Rurik stood in the throat of the cut with the number he had needed. He looked at the fresh fighters, then at the column bearing down on the pass. "Gunnar. Reset the door," he said. "Kjell, put your men on the high rock. We choke this column the way we choked the last." He had found the hands. But the north column was closer now than it had been, and it did not slow. The fight for the pass itself had not yet begun.

The north column reached the throat of the pass before Rurik's fresh fighters could set their feet. He heard the boots first, then saw them come around the shoulder of rock. His mountain men were still climbing to the high stone. The door was not seated. The line was open, and the first ranks broke into a run for the gap. "Gunnar," Rurik said. "How long?" Gunnar knelt at the iron door, driving a pin with the flat of his hammer. Soot streaked his arms. He did not look up. "Not long enough." He struck again. The pin bit. "They're already here." Rurik looked at the running men, then at the two men at the gap. It would not hold. A charge would spill through before the door closed. He counted the seconds he did not have. "Thorin," he said. "The stones above." Thorin stood on the high rock with his father's axe in his fist. He saw what Rurik meant before the words were done. A loose shelf of rock leaned over the throat of the cut, held by nothing but its own weight. "Foolish," Thorin said. "Might bring the whole face down on us." He was already moving. "Get your men back." "Bjorn. With me." Rurik ran for the shelf. Bjorn came without a word, Rurik's belt-knife still swinging at his hip. The two of them set their shoulders against the leaning stone. Thorin drove his axe into the crack behind it and hauled. The first enemy ranks hit the gap. The two defenders there took the charge on their shields and gave a step. Steel rang. A man went down in the mud. The line bent. "Now," Rurik said. They heaved together. Rurik felt the stone give. It ground, tipped, and let go. The shelf came off the rim in a slab and dropped into the throat of the cut. It struck the front of the charge and buried the leading men where they ran. Dust rolled up thick. The rock jammed the gap to a hand's width. No horse would cross it. No rank would push through it. The charge broke on the far side. Men clawed at the fallen slab and found no way through. Behind it, Gunnar seated the last pin and the iron door swung true. Rurik stood on the rim, chest heaving. The gap was choked. The first charge had failed to break his open line, because there was no open line left to break. The column was stopped cold at the throat. Bjorn wiped dust from his eyes. "They'll dig it out." "Let them dig." Rurik looked down at the buried men and the wall of stone he had dropped on them. Thorin leaned on his axe, breathing hard, saying nothing. "They dig one stone at a time. We hold the door. And we make them pay for every hand." The siege was not lifted. But the pass had not fallen, and the column had learned it would bleed to take it.

The stone held, but Rurik could not see behind it. The enemy dug on the far side, hidden by the choke of rubble. He heard picks bite rock. Scrapes. A grunt. But he could not tell if they had cleared one stone or ten. He stood at the iron door with his ear to the seam and learned nothing. "They could break through in an hour," Rurik said. "Or a day. I can't see how close they are." Thorin came up the rock with his father's axe across his back. The old dwarf pressed his palm flat to the fallen slab and held it there. He closed his eyes. "Feel it," he said. "Don't look. Feel." Rurik set his hand beside Thorin's. The stone hummed under his fingers. Each pick strike traveled through the rock as a small shock. Thorin counted them under his breath. "Close," he said. "Too close. They're at the last course." Bjorn spat. "Then we wait for them to fall through and take us one by one." Rurik's belt-knife still hung at Bjorn's hip. He did not soften it. "That's a bad death." Rurik would not wait. If he could not see them, he would make them show themselves. "Gunnar," he said. "Can you unseat the door fast?" Gunnar knelt at the hinges, hammer in his fist. He had driven the pins that closed this door. Now Rurik wanted them out. "Aye," Gunnar said. "But you open that, they pour in." "That's what I want." Rurik pointed at the choked gap. "They think they dig into a blind wall. When the last stone drops, they'll rush it. Blind, in a line, one after another. We open the door beside it and hit their flank as they climb through." Thorin nodded once. "Trap the trappers." Gunnar tapped the first pin loose but held it. They set the line. Rurik put his best men at the door, shields low. He kept his own place at the front. He waited with his hand on the humming stone and counted the strikes. The blows quickened. Then a stone tumbled loose on the far side. Daylight and dust spilled through the gap. The first enemy shoved his shoulders into the hole and started to climb. "Now," Rurik said. Gunnar knocked the pins. The door fell open. Rurik's line struck the flank of the climbing men. The enemy came through blind and bunched, just as he'd said. His warband cut them down in the choke before they could form. The mountain men pressed from the high rock. It was short and ugly. The gap filled with the enemy's own dead, and the digging stopped. Rurik stood in the settling dust. The trap had worked. But the bodies now jammed the gap worse than the stone had. He could not see past them either. And from the north, a horn sounded. The main column had come up behind their diggers, in full strength, and now they knew exactly where his door was.

The horn from the north faded, but the dead still jammed the gap. Rurik pulled his men back from the choke and turned to face the tower behind them. He had put off one debt too long. Bjorn stood at his shoulder, Rurik's belt-knife still hanging at his hip. The gold Rurik owed him sat locked in the enemy's war chest, sealed inside that stone tower, and the tower's iron doors held fast. Until Bjorn was paid, his men fought without heart, and the alliance strained thin. "Your gold's behind that door," Rurik said. "I mean to break it open now." Bjorn folded his arms. "You've said that before." "I've never had the key before." Rurik held up the captured officer's iron ring. He had taken it when he blackmailed the man for the battle plan. "He guarded the chest. He kept the key." Gunnar worked the lock while Thorin watched the north. The old dwarf pressed his palm to the ground, reading the enemy's approach through the stone. "They're close," Thorin said. "You've got no time to count coins." The lock gave. Inside sat the war chest, bound in iron bands. Gunnar split the hasp with two blows. The lid fell back on a heap of Viking coins, worn and stamped, gleaming dull in the tower dark. Bjorn stared at it and said nothing. Rurik dug both hands into the pile and dropped a heavy fistful into Bjorn's palm. "That's your gold. And the price of your clan's sword, paid in full." He held out his hand. "My knife." Bjorn weighed the coins. His face did not change. He drew the belt-knife and set it in Rurik's palm handle-first. "Debt's closed," he said. He did not soften it. Then he turned to the men crowding the tower door. "Rurik pays what he swears. Now we fight for pay, not for promises." It was the most Rurik had heard him say at once. Kjell shouldered through with his mountain men behind him, teeth and claws swinging in his beard. He looked at the open chest, then at Bjorn's full fist. "Good," he said. "Men fight harder with silver in their belts. Mine will." Rurik sheathed his own knife at his hip and felt the weight of it, back where it belonged. He filled a sack with coin and threw it to Kjell for the mountain men. The alliance that had cracked all night pulled tight again in the space of a breath. Thorin's hand came off the ground. "They're at the gap. Now." The horn sounded a second time, closer. The main column had reached the choked dead and begun to climb over their own fallen. Rurik gripped his knife and turned from the empty chest to the door. His debt was paid. His men were his. But the enemy was already inside the pass, and the last fight for Greyspine had come to him.
