Hunger in the Stone

Tarik picked up his calipers and used the fine blade to point to the white flecks in the unreacted half of the cylinder.

"Look at Guardsman Kaan-tay," Tarik said. "His lungs and stomach were packed with mortar dust from Pillar Nine. When we were in the crawlspace beneath Pillar Twelve, three men from your third watch were down in the siphon, tearing the bedding blocks out with their bare fingernails and chewing the slurry like starving dogs. The contamination from the wastes does not merely destroy stone. It alters the physiology of whoever breathes its vapor for more than three seasons."

He leaned forward, his voice cutting through the distant rush of water.

"The human body needs phosphorus to sustain nerve and bone. The black rot starves the infected host of minerals, driving an uncontrollable biological hunger for the very compound Evren-oglu hid in the walls: calcined bone phosphate. Your men are not going mad, Commander. They are starving for the fortress itself. They can smell the bone-ash in the dark, and they are digging it out with their teeth."

Silence fell over the gatehouse, thick and suffocating. Even the rushing sluice beneath the floorboards seemed to fade into a dull, distant rumble.

Yasar-tay let out a soft, wheezing chuckle from the wall. "Three centuries of imperial soldiers eating the fortress that was built to protect them. The poetry of it is almost worth the wet boots."

"Shut your mouth, blind man," Devran growled, but his voice lacked conviction; the corporal was staring at his own boots as if expecting the granite flagstones to open beneath him.

Aysun-bek did not speak. She reached out with a gloved finger and touched the white, frothing crust on the mortar core. She rubbed the residue between her thumb and forefinger, feeling the greasy, granular slip of destroyed phosphate.

"Five pillars," she said, her voice barely audible. "You said five other load-bearing buttresses are vibrating."

"Pillars Four, Seven, Twelve, Fourteen, and Sixteen," Tarik said. "Pillar Twelve is already hollowed at the plinth; the collapse we triggered dropped the intermediate pocket, but the core bedding is gone. If Pillars Fourteen and Sixteen are stripped to the same depth, the entire vaulted ceiling of the lower barracks will come down in a single shear. When that happens, the main curtain wall will lose its foundation thrust and tip six degrees outward into the waste."

"How long?" she asked.

"If the excavation continues at the current pace? Four days. Perhaps five if the reservoir flushes keep the lower conduits flooded."

Aysun-bek rose to her feet. She uncocked the arbalest with a deliberate pull on the cocking stirrup, easing the tension from the heavy steel prod. She hung the weapon from the iron wall hook beside the gatehouse brazier, then turned back to face Tarik.

"You have given me a structural autopsy, surveyor," she said. "Now give me the command reality. Sub-level Four is locked down under Barlas’s writ. The courier has sealed the upper hoist. If I mobilize the Iron Guard to secure the pillars, Barlas will declare this garrison in open mutiny and seal the outer redoubts with oil fire."

"Barlas already knows," Tarik said plainly.

Aysun-bek’s eyes narrowed. "What did you say?"

"Think about it, Commander," Tarik said, wiping his cold hands on his trousers. "Kaan-tay was not a ditch-mender. He was a second-watch sentry assigned to the armory vault. The three men we encountered in Flue Four were wearing standard Iron Guard scale coats. How does a common sentry navigate the Acoustic Veins in total darkness to find the exact inspection pockets where bone-ash was used, while avoiding the solid pozzolana courses?"

Aysun-bek remained motionless, but Tarik saw the slight stiffening of her shoulders.

"The acoustic flues are not marked on garrison maps," she said.

"They are marked on Evren-oglu’s original builder schematics," Tarik countered. "The blueprints kept in the High Spire’s secure archive. Someone above you has been directing these men. Someone who knows precisely which pillars carry the softest mortar, and who has been scheduling watch rotations so the infected can feed without being caught by your patrols."

"That is treason," Devran whispered, gripping his halberd shaft with white knuckles.

"It is architecture," Tarik said. "The rot is not an accident. It is being managed."

Aysun-bek stood in silence for several long breaths. The yellow light of the lantern caught the harsh lines of her cheekbones and the pale, jagged scar running from her left ear to the corner of her collar. Her gaze shifted from Tarik’s calipers to the melted mortar on the crate, and finally to the heavy oak door leading to the upper garrison spiral.

"The watch rosters," she said slowly. "Only three officers have access to the secondary perimeter assignments."

"You, Captain Barlas," Tarik said, "and your duty adjutant."

Aysun-bek did not answer immediately. Her right hand moved instinctively to the hilt of her command broadsword—a heavy, single-edged iron blade in a boiled leather scabbard hung from a brass-buckled baldric.

She paused, her fingers curling around the wire-wrapped grip.

Her brow furrowed. She pulled the sword two inches from its scabbard, inspecting the steel near the ricasso. The metal was clean, honed to a bright, paper-thin edge. But when she slid her bare thumb along the polished iron crossguard, she stopped.

The lower quillon was loose.

Aysun-bek frowned, grasping the cast brass pommel at the base of the hilt. She gave it a firm twist. The threaded pommel nut, which should have required an armorer’s wrench to budge, turned smoothly in her grip, grinding with a faint, gritty crunch.

She unscrewed the pommel completely and set it on the munitions crate. Then she peeled back the dried shagreen leather wrap from the wooden grip core.

Devran leaned closer, his lantern raised high.

The wooden core had been hollowed from the inside. Beneath the split wood, the thick iron tang of the forged blade was deeply pitted, scored with irregular, jagged craters where the metal had been corroded by something far more potent than sweat.

And pressed into the raw, pitted iron were unmistakable indentations: three clean, parallel semi-circles, ground into the metal like the bite marks of human molars.

Tarik stared at the ruined hilt. The grey corrosion around the tooth marks had the exact oily, acidic sheen of the seepage from Flue Four.

"Three nights ago," Aysun-bek said, her voice dropping into a register so low and dangerous that even the rushing water seemed to quiet before it. "I gave this weapon to Lieutenant Berkan. He said the balance was heavy in the pommel and offered to take it to the upper armory to have the tang reset."

Devran’s face went dead white. "Lieutenant Berkan? Commander, he has held the keys to the eastern sally port for four years. He is in charge of the midnight ration wagons."

Aysun-bek did not look at Devran. She picked up the threaded pommel nut, rolling the corroded brass between her fingers. A faint white crust of calcium phosphate flaked away from the threads, drifting down onto the wet stones.

"Berkan was not balancing the blade," she said. Her eyes locked onto Tarik, cold, steady, and stripped of all hesitation. "He was chewing the tang."

Tarik picked up his calipers and slid them into his coat pocket. "The rot is not coming from the lower drains, Commander. It is sitting in your guardroom."

Aysun-bek reached out and took the oilcloth packet containing the remaining cylinder of bone-ash mortar, wrapping it securely and tucking it into her brigandine.

"Devran," she ordered, her voice cutting clean through the damp air. "Lock the distribution gatehouse from the inside. If the High Spire courier demands entry, tell him the sluice mechanism is jammed by debris from the collapse. If he attempts to force the latch, drop the counterweight and flood the stair."

"Understood, Commander," Devran said, his knuckles tightening around his weapon.

Aysun-bek turned back to Tarik, extending a hand to pull him to his feet. Her grip was iron, hard and calloused from twenty years on the border line.

"You wanted access to the foundation junctions, surveyor," she said quietly. "You have it. But we do not go to the pillars."

Tarik wiped the dried grit from his eyes, meeting her gaze. "Where do we go?"

Aysun-bek drew her corroded blade halfway from its sheath, the jagged teeth marks on the tang catching the lantern's yellow glare.

"We go to the armory," she said. "And we see what my lieutenant has been eating for breakfast."
