The Smoke Beacon

Thick, violet steam rose through the floor fissures in pulsing coils, smelling of charred marrow and copper rot.

Ruiseart stood upon the limestone ridge above the nursery pens, his hand resting on the hilt of his bog-iron knife as the screams of the megafauna echoed from the deep vaults below. The sound was a rhythmic, wet bellowing—brood-mothers thrashing against their stone pens as caustic foam filled the primary siphon. Across the lower terrace, herders scrambled with bone rakes and leather baffles, attempting to divert the tainted drainage before the lower wallows drank the vitriol.

"The central cistern took the full charge," Calumh said, coming up the limestone path with his boots wet to the ankles in purple sludge. He spat into a dry crack. "Two breeding dams are already belly-up in the silt. The calves are coughing black phlegm. If that rot hits the south aquifer, we won't have a mouthful of milk or blood-meal left to butcher by midwinter."

"Where did the diver go?" Ruiseart asked. His voice remained level, cut low beneath the roaring of the pens.

"Choked off from the culvert by the third sweep squad," Calumh replied, wiping greasy soot from his brow with the back of a cracked leather forearm guard. "She broke three shield-rims with an iron scraper, took a dart through her gear pouch, and ran east. The boys ran her like a blind hare straight up into the high cul-de-sac."

"The basalt box canyon."

"The very one," Calumh grunted. "Three hundred feet of sheer wall, no overhang, and nothing above it but the dead roof. Unless she grows wings or turns into sulfur smoke, she's standing on twenty paces of loose gravel with her back against the black wall. We've got six men across the cleft holding the neck."

Ruiseart turned from the smoking vent and descended the terrace toward the staging post where four vanguard hunters knelt around a flat slab of shale. At his hip swung the horn case containing the three confiscated blister-ash ampoules taken from the limping scout, along with the four-inch obsidian serrated blade he had peeled from her grip.

He unrolled the heavy hide wrap from his shoulder pack and laid it flat across the stone slab.

Seventeen shards of ceiling obsidian caught the dim, sulfur-tinged light of the chasm: four broad lance-points chipped thin along the bevel, six triangular dart-heads with notched bases, and seven razor flakes whose edges were so sharp they shaved the hair off the skin before the stone even touched flesh. In the lowlands, bog-iron was soft, prone to bending against megafauna ribs and dulling on the third strike. This black glass was pure volcanic strike-stone, quarried from the high roosts where the upper world met the void.

"Gather the ash-wood shafts," Ruiseart commanded.

The four hunters moved without a word, laying out four heavy boar-lances and six short throwing-darts across the slab.

Calumh knelt beside the stone, his calloused fingers hovering over the glass flakes. "Priceless sky-stone, and we're tying it to crooked lowland scrub with wet gut. A craftsman from the high clans would slit our throats just for the insult."

"A craftsman from the high clans is currently cornered in our rock chimney," Ruiseart said. He took the first broad lance-head, seating its tapered tang into the notched end of a four-span ash haft. He took a strip of damp rawhide from his belt pouch, winding it in tight, crossing diagonals behind the flint shoulder. "Bind them with triple sinew and smear the wraps with dried pine gum. If a head twists on impact, you answer to me."

Calumh picked up a triangular dart-head, fitting it to an ash shaft with practiced ease. "The one in the cul-de-sac isn't the crippled one we tied to the culvert peg. The sweep squad said this one moves without a limp and throws stone like a siege-engine. She dropped Torcall with a hand-flung rock from forty paces before she hit the gravel."

"She carries the last of their poison," Ruiseart said. He pulled the rawhide knot tight with his teeth, knotting the cord and testing the blade's seating against the palm of his hand. The edge drew a hair-thin line of crimson across his skin before he felt the sting. He did not wipe the blood away. "And she carries the rest of the obsidian."

"We could smoke the cleft," Calumh suggested, blowing into his chilled palms. "Roll three bundles of wet scrub into the mouth, set a spark to the pitch, and let her choke on her own medicine. Saves us four good lances and a lot of blood."

"No," Ruiseart said. "Smoke ruins the pitch tubes if she has them cached on her ribs. We take her gear whole. Every tube of distilled tar, every scraper, every scrap of glass."

He lifted the finished lance. The obsidian point sat true, black and mirror-smooth against the pale wood. Behind him, the four hunters finished their bindings, their eyes fixed on the razor-sharp dart tips now gleaming in their hands. They had spent three winters hunting massive, thick-hided trench-beasts with blunt bog-iron picks; the sight of true weapons-grade glass transformed the tension in the camp into quiet, lethal certainty.

Ruiseart took a small horn jar of raw pitch from his pack, dipping his thumb into the viscous black resin. He traced a narrow line of tar along the groove behind the lance-head's shoulder, stopping well short of the stone edge itself.

"Remember the cardinal draft," Ruiseart told the squad, looking at each man in turn. "If you light the pitch, you have thirty seconds before the stone burns out and the wind reverses. You throw on the rising draft only, toward the high seam. Throw downward against the floor gravity, and the pitch will tear your wrist out of its socket when the displacement bites."

"Understood," Calumh murmured. He hefted two glass-tipped darts, a dry smirk touching his gray-bearded mouth. "I prefer my wrists attached. Lowland women are picky about one-handed husbands."

"Form the line at the cleft," Ruiseart ordered.

He turned toward the eastern rise, leading the five men up the gravel path where the nursery floor gave way to the jagged basalt formation. Above them, the vast chasm yawned in eternal twilight—a thousand feet of empty air hanging between the moss-clad floor and the distant, inverted ceiling roosts. The violet plume from the poisoned cistern was spreading now, forming a wide, luminous bruise across the upper thermal currents.

They reached the narrow entrance of the box canyon within minutes.

Two lowland sentries knelt behind a barricade of split shale at the gap, heavy shields braced against their shoulders. Through the ten-pace gap between the sheer basalt cliffs, the canyon opened into a circular floor of crushed stone, enclosed by three hundred feet of polished, vertical rock.

At the far rear of the enclosure, standing with her back pressed against the black stone wall, the solitary ceiling diver stood waiting. Even in the gloom, her posture was unmistakable: light, balanced on the balls of her feet, her hands low and ready, clutching a single broad obsidian point.

Ruiseart stepped between the shale shields and halted at the mouth of the gap. He raised his left hand, signaling the four dart-throwers to fan out along the rim of the shale barricade with their glass points leveled.

With his right hand, Ruiseart drew the four-inch serrated knife taken from the captured diver, turning its jagged black edge toward the woman trapped against the stone.

"You ruined the cistern," Ruiseart called out across the gravel, his voice carrying flat and heavy through the enclosed space. "Now you will give up your glass, or we will pin you to the floor."
