The Narrow Ascent

How many paces of solid stone lay between the lower sump and the clan fire before the red dust choked the draft? Mátyás wedged his boots into the wet calcite seam, his bare right forearm stinging where the screaming face had ripped his sleeve away, and hauled himself into the mouth of a forgotten bypass fissure. The main northern chimney was clogged with active ochre, leaving only this unmapped side-vent. He needed to reach the upper ledge before those crimson footprints reached the draft flue. If the living pigment struck the hearth while the families slept, no bone awl or chant would peel the stone off their chests.

Behind him, Hajnalka’s horn vial cast a thin, cold teal shimmer across the shale. The light showed the crimson trail five paces back: fine red particles hopping from gravel to gravel, rolling together, forming small heel-marks that pressed into the rock and climbed without pause.

"The air is warm up there," Boglárka muttered from the bottom of the slot. She tapped her ash staff twice against the limestone floor, tilting her ear toward the ceiling. "The great hearth draws the chimney draft like a thirsty lung. The dust smells the fat in the ash. It is hurrying."

"Then do not lag," Mátyás said, though his throat felt as dry as calcified bone.

The chimney narrowed three paces in. The limestone walls pinched together until the gap was no wider than a man’s ribs. Cold subterranean moisture wept from vertical fractures, slick with greasy clay. Mátyás pressed his back against the hanging wall, brought his knees to his chest, and hitched upward. The stone clamped against his shoulders, catching the rough seams of his hide vest. The darkness above was thick and heavy, smelling of old bat dung, sulfur, and stagnant brine.

His lungs locked against his ribs. The ceiling seemed to drop an inch with every breath he drew, pressing down on the bridge of his nose, threatening to seal him inside a solid block of grey calcite.

A ridge hunter belongs under the open gray sky, he thought, grinding his molars until his jaw ached. Not inside the belly of a dead mountain.

"Mátyás," Hajnalka called softly from below. Her whisper carried the flat slap of stone against leather. "The rear prints are picking up speed. The cold moss slows the ones near my boots, but the trail behind is thickening."

"The chute is blocked," Mátyás rasped. He forced his hands above his head, fingers searching the dark. His knuckles struck a wedged limestone slab, a fallen roof flake that had jammed sideways across the squeeze point. It left only a four-inch slit for the updraft. "Give me room."

He unslung his short iron-shod spear from across his shoulders. Working within a nine-inch radius, he could not swing with his arms. He braced his heels into a hairline ridge on the left wall, locked his spine against the right, and rammed the solid iron butt of the spear into the slab’s bedding plane using the leverage of his wrists.

The impact vibrated through his collarbone. Cold rock dust showered his eyes and mouth. He struck again, finding the natural grain where water had thinned the mineral crust. With a sharp crack, the fractured slab split along its spine. Mátyás caught the larger half with his knees, guiding the heavy stone down between his calves so it would not drop onto Hajnalka’s head.

"Catch," he grunted, lowering the slab into her waiting grip.

Hajnalka set the flat rock against the wall behind her, creating a makeshift barrier that temporarily dammed the narrow floor. "The fissure is open."

"Barely," Mátyás said. He exhaled all the air from his chest, collapsing his ribcage until the stone grazed his sternum, and slid his torso through the cleared throat of the chimney.

The rock scraped the scabs along his bare right arm, opening shallow beads of blood against the limestone, but his hips cleared the pinch. He reached down into the dark, hooked his fingers under Boglárka’s wool mantle, and hoisted the old chanter through the opening.

Boglárka landed on the shelf beside him with the lightness of dried birch twigs, sniffing the close air with noisy satisfaction. "You wheeze like a badger stuck in an alder root, boy. A proper hunter should learn to breathe through his ears when the rock gets greedy."

"My ears are busy listening to the mountain trying to eat my boots," Mátyás said, pulling Hajnalka up behind her.

Hajnalka scrambled onto the ledge, her breath coming in ragged gasps. The horn vial in her fist pulsed with dull blue radiance, illuminating the steep ramp ahead. The chimney opened into a wider joint fissure that cut diagonally upward through the strata, worn smooth by ancient torrents that had vanished long before the sun failed.

Above them, the faint smell of burning cedar and charred marrow drifted down through the cracks. It was the rich, greasy smoke of the Great Chamber, carrying the warmth of three clan hearths.

"The trail is branching," Hajnalka whispered, pointing the vial downward.

Through the narrow throat they had just climbed, the red dust had overrun the stone slab Mátyás had dislodged. The crimson grains no longer moved as isolated footprints; they were spreading out like creeping lichen, following the micro-fissures in the bedrock, pulled inexorably toward the heat above.

"They want the main draft," Mátyás said. "They are not trying to catch us. They are trying to reach the fire before the grease burns down."

He turned and scrambled up the slick ramp, using his hands and knees to scramble over smooth travertine steps. His claustrophobia receded, swallowed by the urgency of what lay at the end of the climb. Pausing at the ramp's turning, Mátyás pulled Tivadar's notched slate from his belt and drew a flint point across the soft stone, etching the bearing and pitch of this unmapped bypass chimney onto the slate. They now had a secure passage connecting the lower sumps to the high gallery without passing the waking ochre walls.

After thirty paces of steep ascent, the fissure terminated at a natural limestone balustrade seventy feet above the floor of the Great Chamber.

Mátyás dropped to his stomach on the cold rim, peering over the edge. Hajnalka and Boglárka crept up beside him, shielding the bioluminescent moss beneath a flap of sheepskin so its strange blue light would not betray their position.

Below them, the Great Chamber stretched out into the vast, cavernous dark.

The clan fire burned in the center of the hall, a massive heap of split larch logs and dried tallow cakes radiating cherry-red heat into the vaulted ceiling. Around the perimeter, several hundred refugees lay huddled in family clusters under heavy furs and greasy hide tents. The River Clan slept along the western bank of the sunken pool, their spears stacked in neat tripods. The Ridge hunters occupied the drier eastern benches, while the Grotto Keepers tended the peripheral braziers near the sacred painted panels.

Everything appeared peaceful. A solitary sentry sat on an upturned boulder near the woodpile, nodding over his stone-tipped spear.

Then Mátyás looked at the rising columns of smoke.

The heat from the great fire rose in thick, shimmering waves toward the vault, where the ancient red deer paintings were stenciled across the limestone dome. A pale, reddish mist had begun to form beneath the ceiling arches, drifting like fine flour caught in an eddy.

"The soot is taking the pigment," Hajnalka whispered, her knuckles whitening against the rock rim. "If that dust settles into the grease on the sleeping furs, it will bind them into the floor before morning."

Mátyás reached down and tightened the rawhide lacing on his left boot, his jaw setting hard against the ache in his bruised arm.

"The elders will call it madman's talk if I shout from the gallery," he said, turning his back to the drop. "Get down to the sacred wall, Hajnalka. The stone already took your brother's stencil finger. Check if the remaining perimeter bindings are still holding or dissolving. If the clan won't douse the hearth, we break the soot ourselves."
