The iron latch on Syla’s front door resisted for half a second before the heel of Varnok’s boot sheared the rusted screws straight through the frame. The heavy oak plank swung inward, slamming against the log wall with a hollow thud that was instantly drowned out by a hiss of trapped, oily heat. A blast of furnace air struck his face, carrying the rank, sickening stench of boiled pine needle and roasted marrow. His lungs revolted, the grease coating the roof of his mouth. It wasn't the honest, ash-dry warmth of birch cordwood; it was a swampy, suffocating vapor that clung to the skin like wet wool. Across the room, an iron stove glowed a dull, diseased russet, belching billows of pale emerald through every warped seam of its pipe. "Get away from the latch!" Syla shrieked. Her voice cracked, ruined by soot. "Shut it! Shut the frost out!" She dropped to her knees before the open grate, her skirts blackened and stiff with scorched tallow. In her blistered hands she clutched a cleaver and a freshly severed limb. The thing was as thick as a grown man’s forearm, but the skin had hardened into ridged, gray alder bark, oozing amber-colored resin from a jagged stump. Five knobby twigs jutted where fingers should have been, curling inward toward the severed palm like dying spiders. Behind her, embedded into the cedar planks of the northern wall, was her husband, Renald. Or what the taiga had left of him. His pelvis and legs were entirely subsumed into the foundation logs, thick fibrous boles crawling upward across his ribcage like parasitic ivy. His remaining arm hung limp, split into three boughs at the elbow. The man's head tilted back against the timber, his lips swollen, gray, and fused together by sticky pitch. Thick, clear resin ran from the corners of his milky eyes, dripping steadily onto his chest with the slow rhythm of melting icicles. Every shuddering pull of air he took sounded like dry reeds grating against stones. "Syla, put the cleaver down," Varnok commanded, stepping over the threshold. He didn't close the door behind him. The frigid air of Osk-Vallen immediately began pouring across the threshold, rolling along the spruce planks like white smoke. "Shut that door!" she screamed again, her face wild, her hair matted with sweat and flecks of ash. She shoved the severed wooden arm into the mouth of the stove. The flames flared a blinding, toxic jade. The iron pipe hummed with unnatural heat, and a wet, popping crackle echoed from the firebox as bone and wood burned as one. "You want them to freeze? Is that why you came back, lake-rat? To watch my babies turn blue?" From the far corner, beneath a mound of musty reindeer hides, came a chorus of ragged, wheezing gasps. Two small figures lay tangled together. Little Hanne, barely six winters old, curled into her older brother, Bram. Both were drenched in sweat, their cheeks flushed a feverish, unnatural plum. Bram coughed, a dry, barking spasm that rattled deep in his sternum. When he pulled his small fist away from his mouth, tiny flecks of pale sawdust and green phlegm speckled his pale skin. Along his knuckles, the skin was already tightening, stretching tight and shiny over hard, knotty bumps. "Look at their hands, Syla," Varnok said, his voice flat, stripped of pity. He pointed a leather-wrapped finger toward the bed. "Look at what you’re feeding them." "I'm giving them heat!" She snatched a heavy, bone-handled skinning knife from the prep table, brandishing it with wild, erratic jerks. Her knuckles were scalded red, peeling from the stove's unnatural fury. "Without the stove, the cold takes their toes by midnight. It takes their ears by dawn. Renald understands. He gave it to me! He let me take it so they wouldn't die!" From the wall, Renald produced a wet, tearing groan. A single wooden twig on his shoulder snapped under the strain of an involuntary spasm, spilling a thick drop of sap onto the timber. "Renald ate the elk's flank," Varnok said, stepping forward. His boots crunched on the frozen crust of snow drifting through the open entrance. "Torvak gave him the meat, and the curse took root in his belly. Now you burn his cursed marrow, and your children breathe the cinder. Look at Bram's throat. That isn't soot. It's roots, woman. You are planting a grove inside their lungs." Syla lunged. Grief and madness had stripped away whatever reason the village had taught her. The iron blade arced toward Varnok’s throat, driven by the hysterical strength of a mother backed into an abattoir. Varnok didn't flinch. Out on the ice sheets, a miscalculated lunge meant drowning beneath three feet of black slush; he was accustomed to violence that offered no second chances. He stepped inside the arc of her arm, his forearm striking her wrist with the dull crack of dried horn. The knife flew from her slick grip, skittering across the floor and sliding beneath the woodbox. Syla crashed against his chest, beating her fists against his heavy beaver-skin coat. "No! No, you bastard, don't touch it! Don't you put it out!" He caught both her wrists in one massive, calloused hand, twisting them behind her back until she gasped and sank to her knees. With his free boot, he kicked the iron door of the stove wide open. The glare of the green coals threw grotesque, stretching silhouettes across the cabin rafters. The heat radiated outward like a physical slap, scorching the hair on the back of his hand. "Bram! Run to the elder's!" Syla shrieked into the floorboards, wailing openly now, her forehead pressed against the sap-slick spruce. "He’s killing us! He’s putting out the fire!" Bram couldn't run. The boy tried to push himself up on the cot, but his wrists buckled. He fell back into the hides, retching into the blankets, a bloody spray of amber resin spilling from his lips. Varnok dragged Syla away from the stove, depositing her roughly on the bench beside the dining table. "Stay there, or I break your arms. Then there will be no one left to bury them." He turned back to the stove. There was no water bucket; anything liquid left away from the hearth had long since frozen solid. He didn't hesitate. He grabbed the iron ash shovel leaning against the brickwork, stepped out into the doorway, and began scooping deep drifts of blue-gray snow from the porch, hurling them straight into the belly of the stove. The reaction was instantaneous and violent. The burning bone-wood screamed—a piercing, subterranean shriek that rattled the cups on the shelves. A blinding torrent of superheated steam erupted from the iron belly, smelling of sulfur and boiling resin. Varnok thrust another shovel full of packed crust into the coals, then another, burying the hissing, dying embers beneath a heavy sludge of melting ice. With a final, gargling choke, the green light died. Pitch blackness fell over the cabin like a dropped canvas. The only sound was the frantic, shuddering gasp of the two children and the rhythmic *drip-drip-drip* of leaking sap against the wood. Then came the air. Without the furnace heat to hold it at bay, the true frost of the Osk-Vallen night surged through the open doorway. It wasn't a slow cooling; it was an executioner's blow. Within seconds, the thick steam that had filled the room crystallized in mid-air, falling to the planks as a fine, sharp frost. The cedar walls began to pop and groan, the moisture within the wood contracting instantly under the sub-zero assault. Syla gave a strangled moan from the bench. Her teeth began to chatter, a sharp, clattering percussion that shook her entire frame. "It's cold," she whispered, her voice shrinking into the dark. "Gods, Varnok... it’s so cold..." From the bed, little Hanne began to whimper, a thin, fragile sound that quickly dissolved into violent, uncontrollable shivering. The air inside the cabin had plummeted past the threshold of survival, dropping thirty degrees in a dozen heartbeats. Varnok stood in the center of the dark room, his breathing calm, slow, rhythmic—the rhythm of a man who had slept on open ice under the shroud-stars. But as he looked toward the trembling mound of furs in the corner, where the children's frantic breaths puffed in plumes of freezing mist, the cold consequence settled hard in his gut. He had starved the blighted smoke. But the night was only three hours old, and the frost was already reaching for their marrow.
