Mango Chiefton knelt in the mud and stabbed his own arm again. The bone needle bit shallow. Ash-black ink welled up, then thinned to gray within an hour. He watched the mark fade like the last three had faded. He needed these lines to hold. His troop needed them to hold. A beast old as the swamp stalked their sleeping ground, and only a full-body binding ritual could chain it. But a binding ritual demanded deep lines that lasted a lifetime. His crude needles could not cut that deep. He had lost two cousins to the beast already. He pressed the needle to his skin a fourth time and drew blood, not ink. His hand shook. The tool was too soft, too dull. Every mark he made was a promise the beast would break. Mango stopped. He lifted the ornate bong at his side and packed the bowl with a torn violet leaf. He had traded a moon of foraging for that leaf. The elders swore its smoke opened the trance a true ritual required. He lit it, drew deep, and held the smoke until the swamp bent sideways in his eyes. In the trance, he stopped seeing his arm as skin. He saw it as a thing that could be carved by something hungrier than bone. He crawled to the neglected fence at the edge of camp, where wild weeds choked the rotting posts. Beyond it, the shallows churned. A swarm of marsh piranhas boiled in the murk, teeth flashing, bodies never still. Small. Fast. Their bites cut clean and deep. Mango understood then. He could not force the lines. He would let something else bite them. He smeared a stripe of ink-paste across his forearm in the shape of the first binding rune. Then he plunged the arm into the shallows and held it there. The piranhas struck. Pain ripped up to his shoulder. He roared and kept the arm down, dragging it slow so the teeth followed the paste line. They tore where the ink led them, hungry for the scent he'd mixed in. When he wrenched the arm free, blood sheeted off it. He fell back against the fence and scrubbed the wound clean. Under the mess, the rune sat carved into muscle, ragged but deep. He packed fresh ink into the raw grooves. This time it would not thin. This time it would scar and stay. Mango laughed, wild and ragged, blood dripping off his fingers. He had his tool. He had a way to cut lines the beast could not erase. But one rune had nearly emptied him. The full ritual covered his whole body, dozens of runes across chest and back and legs. No creature would let him drain that much blood and live. And the fish would strip flesh faster than the marks could set. He needed the lines to grow instead of bleed him dry.

Mango pressed a rag to his carved arm and watched the blood soak through. One rune had nearly killed him. Dozens waited. He could not keep bleeding out for each line. He wrapped his arm tight and set off across the shallows, hunting the old ink parlor the elders whispered about. If any place held a shaman's secrets, it was there. The parlor slumped between rotted posts. Its sign hung cracked, the paint long gone. Mango shoved the door and stepped into dust and cobwebs. Faded chairs. Empty jars. On a shelf he found bundled sticks of pale incense, ground from bone. Beside them lay a broken bone stencil, its edges worn smooth by old hands. Someone had carved runes here before him. He gathered both and turned to go. A shape moved in the doorway. Mango raised his fists. "Easy," the shape said. It was Riko Quickpaw, his young cousin, thin fingers already busy shaving a splinter of bone to a point. Riko had trailed him from camp. The boy carved fishhooks so fine they looked like hair. "You bleed too much, cousin. The whole troop smells it on you. I want to help before the fish take you next." Mango almost sent him away. But he looked at the wrapped arm and the dozens of runes ahead. He held out the incense and the stencil. "Then help." Riko chewed his lip. He crossed to the shelf and pulled down a glossy bulb, red petals wet in the gloom. A swamp poppy. "My mother chews this for pain. It kills feeling in the skin." He crushed the bulb and smeared the pulp along a fresh line on Mango's chest. The skin went numb and cold. "That stops the hurt," Mango said. "Not the bleeding." Riko lit a stick of the bone incense. Pale smoke curled up. He waved it over the numbed skin. "The old master burned this over his cuts. Watch." Where the smoke settled, the raw grooves from the first rune stopped weeping. The blood thickened and crusted fast. Mango stared. He pressed the numbed patch. No fresh blood came. The smoke sealed the wound as the fish carved it. They worked through the night. Riko chewed poppy pulp and packed each planned line. He burned the incense low over the fresh cuts. Mango waded to the shallows, smeared the paste, and gave his skin to the teeth. This time the piranhas bit and the smoke closed the grooves behind them. He carved four runes before dawn and stood upright, pale but breathing. Riko wiped his hands and grinned. "See? You keep the ink. You keep the blood." Mango touched the four fresh runes on his chest. He would live long enough to finish now. But four had taken a whole night, and dozens remained. The beast still walked the sleeping ground. Time, not blood, was the enemy now.

By the next dusk, Mango had five runes and fresh cuts weeping under the wraps. The beast smelled them. It came at nightfall, a lean gray wolf with six eyes glowing red and green through the fog. It circled the parlor, snout low, drinking the scent of his blood. Every time Mango crouched to smear paste and start a line, the wolf slammed the wall and forced him back. He couldn't hold still under the teeth. He couldn't carve while it hunted him. "We move it, or you die on the floor," Riko said. The boy pressed his back to the door. "It wants your blood. Give it another." Mango thought of the boar he'd found stiff in the reeds that morning, split open and heavy with old blood. "The dead boar. It reeks worse than me." He nodded to the far shallows. "Drag it downwind. Pull the wolf off my scent." But neither of them could drag it far with the wolf between them and the door. Then the door shoved open. A young hunter stepped through, half wolf himself, black ears pinned back, claws out. Mango had seen him track boar through the marsh, always alone, always too fast for sense. Fenrir Kane. He grinned at the six-eyed wolf like he'd been waiting all his life for it. "That thing's been eating your troop?" Fenrir said. "Good. I've wanted a real fight." "Don't," Mango said. "It's faster than you." "Everything's faster than everything until it isn't." Fenrir snatched a length of bone from the shelf and bolted outside. He whistled sharp and slapped the beast's flank. The wolf spun. Fenrir led it away from the wall in a wild loop, ducking snaps, howling to keep its six eyes on him. "Now," Riko hissed. Mango and Riko heaved the boar carcass out the back and hauled it through the mud. Blood smeared their arms. They dumped it in the reeds downwind and ran back. The wolf's head snapped up. It caught the thick reek of dead boar, dropped Fenrir, and bounded toward the reeds to feed. Fenrir stumbled through the door, panting, one arm raked and bleeding. "See? Slow enough." The wall stopped shaking. Outside, the wolf tore into the carcass, far from Mango's scent now. He didn't waste the gap. He crouched, smeared the paste along his ribs, and waded to the shallows where the piranhas waited. Riko chewed poppy and burned the incense low. Mango gave his skin to the teeth. This time no wall shook, no snout hunted him. He carved through the dark. By dawn he had eleven runes. But the boar was bone by morning, and the wolf would come back for the only fresh blood left. The bait had bought one night. It would not buy another.

By midday the boar was picked bones. Mango stood in the parlor and counted his runes: eleven dark scars along his ribs and arms. Dozens more to go. The wolf would smell his wounds by dusk and come for the last fresh blood in the marsh. He needed bait that lasted, not one more corpse. Riko dumped the ink-paste bowl and shook his head. "No more boar out there. Nothing dead but us soon." Then a woman staggered through the broken door. She was young, curvy, mud to the knees, eyes wild. She'd run a long way. She held a metal jar tight to her chest, its lid sealed with wax. Inside sloshed something thick and brown. The smell hit Mango like a fist. Musk. Wild and rank, worse than any dead thing. "You're the ones carving," she said. Her voice came fast and clipped. "It's tracking blood. I know. It killed everyone in my house." She stopped herself. "Doesn't matter. This jar. It's how I lived three days." "Who are you?" Mango asked. "Valentina. Don't waste time." She thrust the jar out. "Beast musk. Smear it and it can't find your scent under it. That's how I hid." Mango took the jar. His hands shook. This was better than a rotting boar. Musk didn't rot. Musk could hide him for as long as it lasted, and he could spread it thin over many nights. But Valentina's arms were bare and shaking. If she gave the jar away, she had nothing left to hide behind. "This kept you alive," he said. "You're giving me your only cover." "I'm not staying in this swamp," she said. "You bind it, nobody needs to hide. Do it or don't." Mango pried the wax free. The stink boiled up. Riko gagged and stepped back. Mango dipped two fingers and dragged the musk over his wounds, over the fresh cuts, over the paste lines he still had to carve. The smell buried his blood completely. He waded to the shallows. Riko chewed poppy fast and pressed it to his skin, then lit the bone incense low. Mango smeared paste along a fresh line and gave his arm to the piranhas. Their teeth cut deep. No wall shook. No snout hunted him. The musk held. He carved all afternoon and into the dark. At dusk the wolf came close. Mango heard it snuffle the reeds beyond the wall. It circled, confused, snapping at empty air. It could not find him under the musk. It slunk off hungry. By dawn Mango had nineteen runes. The jar was near empty. He wiped the last smear from the bottom and knew it would not cover him tomorrow. But the wolf hadn't tasted his blood, and Valentina still sat by the door, arms bare, no cover left, watching the reeds where the beast had gone.

Dawn broke gray over the marsh. Mango wiped the last musk from the jar bottom and rubbed it into his fresh cuts. The stink covered his blood one final time. But the woman who gave him that cover sat by the door with bare arms and no scent to hide behind. He had taken her only shield. Now the wolf that hunted them both would smell her first. Valentina stared at the reeds where the beast had slunk off. "It'll come back," she said. "For me now. Not you." Mango knew she was right. She'd traded her life for his runes. He had nineteen marks and dozens still to carve. If the wolf killed her, he lost the only helper who could keep his skin masked. He needed her alive as much as she needed shelter. "Riko," Mango said. "Where's the closest safe roof?" Riko wiped ink from his small hands. "The tree house. Upriver. It's built like a cage. Bars all around one side. Nothing gets in." Mango pictured it. A home wrapped in iron latticework, raised on a thick trunk above the water. The wolf could climb, but it could not bend those bars. "We move now," Mango said. "Before the sun's full up." They ran. Mango smeared the dregs of musk across Valentina's shoulders, sharing what little cover was left. It was thin. It would not last. But it might buy them the trip. Halfway there the reeds thrashed behind them. Six eyes gleamed low in the mist. The wolf had caught her scent under the fading musk. It lunged. Mango shoved Valentina ahead and hurled the empty jar at the beast's snout. It flinched. Riko scrambled up the trunk first, quick as his name, and swung down a rope of vine. Valentina climbed. The wolf snapped at her heels. Mango grabbed a hanging root and kicked hard at the beast's jaw. Teeth grazed his calf. Blood welled. The wolf smelled it and surged up the trunk after him. Mango hauled himself onto the platform. Riko slammed the caged door and dropped the bone latch. The wolf hit the bars full force. The whole house shook. Six eyes glared through the iron. It could not fit its head between the gaps. Inside, on a shelf, sat a strange offering left by whoever built the place. Half a banana, half raw meat, fused into one uncanny slab. Riko grabbed it and flung it through the bars. The wolf tore into the meat side and dragged it off into the reeds. Valentina slid down the wall, shaking, alive. "You came back for me," she said. "You gave me your cover," Mango said. "Now you've got walls instead." He looked at his bleeding calf, then at the nineteen runes on his ribs. The safe roof held. But the musk was gone. He had no scent-cover left to carve behind. He needed a new way to hide his blood, and soon.

Mango knelt by the cage bars and shook the incense box. Two chips of bone-ash rattled inside. He had counted on the smoke to seal each cut. Without it, his next runes would bleed until they drained him. He had nineteen marks. He needed dozens. The math was simple and cruel. Cut more, and he would die on the floor of this cage house. Riko crouched beside him. "How many carvings left in that box?" "Two, maybe three," Mango said. "Not enough for even one rune." Below, the wolf circled the trunk. It had finished the meat side of the strange offering and dropped the banana half in the mud. Its six eyes watched the platform. Mango's cut calf throbbed. He could not carve while the beast waited to smell fresh blood. Valentina rose from the wall. She lifted an ornate bong from a corner shelf, left by whoever built the place. Skulls curled around its glass. Runes crawled up its neck. "You breathe your violet leaf through this," she said. "But look. The bowl is bone. And the base is packed with ash." Mango took it. He tapped the base. Gray powder spilled into his palm. Not weed. Burned bone, ground fine, the same stuff that sealed his wounds. Someone had filled the bong with it long ago. "There's more in here than three carvings," he said. His hands shook. "There's a full night of smoke." He scraped the ash into his empty box. It filled to the brim. But burning it needed heat and a way to steer the smoke onto raw skin. Riko solved that. He wedged the bong upright and packed the bowl with the bone-ash. He lit it with the last coal from their fire pot. Smoke rose thick and sweet. Mango numbed his ribs with the poppy paste. Then he coated fresh lines with scented ink and pressed his side to the bars where he could reach the river below. He would not use piranhas here. He used the stencil and a sharpened bone sliver, cutting slow and deep. Blood welled. "Now," he said. Riko cupped the smoke and pushed it against each open cut. The wounds hissed and closed. No blood dripped. The wolf below lifted its snout, caught nothing, and paced off in confusion. Mango carved through the night. Ash smoke sealed every line. By dawn he had four new runes. Twenty-three in total. His hands were steady. His skin held. The drain that would have killed him never touched him. He set the bong down. The base was empty now. The bone-ash was spent, all of it, poured into this one night. "We're out," Riko said. "For good this time." Mango looked at the twenty-three marks. Dozens still uncut. He had the runes to finish and no smoke left to seal them. Somewhere in Sloughwater there had to be more bone-ash. He would have to leave the cage to find it.

Mango spread the shaman's stencil on the platform floor. Dawn light showed what the dark had hidden. The bone plate was cracked down the middle. Its carved rune channels had worn thin as thread. He pressed his sharpened bone sliver into a groove and dragged it. The line came out crooked, smudged at the turn. He wiped it and tried again. Worse. A smudged rune could break the whole binding. "It's finished," he said. "The stencil's dead. I can't trace clean lines without it." Riko crouched beside him and ran a thumb along the crack. His young cousin had the steadiest hands in the troop. He had crafted finer needles for Mango before. "Then stop tracing," Riko said. "You don't need the plate. You need the pattern." "I can't carve dozens of runes freehand. One slip kills the binding." Riko pulled the cracked plate closer. He tilted it to the light and studied each worn channel. "I'll cut a new stencil," he said. "Same runes. Fresh bone." He looked at the empty offering by the bars, the strange banana and meat mash the wolf had left in the mud below. "But I need a hard, flat piece. Bigger than that scrap." Mango's stomach turned. He knew the only tool in the cage with a broad bone head. He lifted it from the corner where he had leaned it. The skull hammer. Its striking face was carved with old marks, wide and smooth. "This," he said. "You can cut a stencil from the flat of the head." Riko took the hammer and weighed it. "It's thick. My hands will cramp before I finish." Mango broke off a violet dreamvine leaf and pressed it into Riko's palm. "Chew it, don't smoke it. Just enough to steady your grip." Riko chewed. His breathing slowed. He wedged the bone sliver against the hammer's flat face and began to carve. He worked all morning. Mango held the old plate as a guide while Riko copied each worn rune onto the fresh bone. The boy's cuts were clean and sharp where Mango's had smudged. Below, the wolf circled the trunk, six eyes turned up, waiting for blood that never dripped. By noon Riko set the hammer down. The flat of the skull now held a full row of clean rune channels, deeper and truer than the shaman's worn plate. He passed it up. Mango pressed his sliver into the first groove and dragged. The line came out sharp, no smudge, no break. "It holds," Mango said. But the new stencil was smaller than the old. It carried fewer runes at once. Each pressing would take longer, and he still had no smoke to seal the cuts. He looked at the wolf below, then at the river, then downstream toward the far glow of a lantern-lit club he had passed once. Somewhere down there, men burned bone for many things. He would have to go and find more ash.
