House of Blood

The cold stone wall of the subterranean conduit felt damp against the back of Valen’s glove. Overhead, heavy granite archways carried a faint residue of green moss that smelled of turned soil and old river silt.

Mirain released Valen’s left sleeve and stepped back one pace. Her violet eyes remained fixed on the dark-mithril suppressor guard strapped around his forearm. The metal had settled back into its dull, matte-black finish, the faint crimson pulse disappearing completely into the dense alloy.

”The air-intake gauge at the archway marked the nitrogen levels at two percent,” Mirain said. Her tone had returned to its rigid administrative clarity. ”The filter masks will remain in our supply kits unless the secondary seals show a pressure drop.”

”The ambient airflow is coming from the south,” Valen replied, rebuttoning his dark wool sleeve over the suppressor guard. ”The draft indicates an unsealed ventilation shaft connected to the lower levels of Sector Three.”

Mirain looked down at the crushed bone fragments scattered across the floor.

”These constructs were wire-bound skeletal frames. The alchemical scholars in Sector Three use this specific copper-wire threading for basic laboratory haulers. They do not possess the authority to field-test them in restricted historical vaults.”

”They were not field-testing them.”

Valen crouched and picked up a three-inch section of the black wire that had held the lead construct’s spine together. He brought it close to his blindfold, turning the metal strand between two fingers.

”The wire is etched with a continuous directional rune. It was not programmed to attack live targets.”

Mirain stepped closer, her leather boots crunching on a fragment of skull.

”Explain.”

”The wire was programmed to walk thirty paces west, collect stone debris from the collapsed foundation wall, and return to the eastern shaft,” Valen explained. ”When you drew your crimson rapier, the high-frequency vibration of the steel disrupted the directional rune’s magnetic alignment. The construct rerouted its command to neutralize the nearest kinetic disturbance.”

Mirain studied the wire.

”So drawing my weapon turned a harmless maintenance construct into an attacker?”

”More accurately, it caused the construct to misidentify you as an obstruction to its assigned task.”

”That distinction is unlikely to comfort anyone who gets their skull crushed.”

”Fortunately, the incident has been contained.”

Before Mirain could respond, a heavy metallic mechanism ground into motion deep behind the stone wall to their right.

Click. Clack.

The sound was low and rhythmic, sending a faint vibration through the basalt flagstones beneath their feet.

Mirain’s hand returned instantly to her rapier.

”That is not a structural settling sound.”

”It is a counterweight pulley system,” Valen stated. ”Operating on a twelve-second cycle.”

”The semester trials do not begin for another five days.” Her eyes narrowed as she scanned the dark corridor ahead. ”The preliminary inspection team was not scheduled to clear this section until Thursday morning. Someone has activated the subterranean floor gates ahead of schedule.”

”The activation was manual.”

Valen raised his brass lantern and directed its yellow beam toward the base of the nearest support pillar.

”The lever housing at the corner has fresh machine oil dripping onto the stone. It has not yet absorbed the surrounding dust.”

Mirain approached the pillar.

A heavy iron lever sat flush against the stone face, its surface coated in a slick layer of yellow lubricant. A single drop gathered at the end of the handle before falling to the floor with a soft plop.

”Who pulled it?” she asked.

”A person weighing roughly one hundred and forty pounds. Wearing standard Citadel-issue boots with worn heels.”

Valen tilted his lantern toward the damp stone beside the lever.

”The left boot impression is approximately three millimeters deeper than the right.”

Mirain examined the footprint.

”A student cadet? Or a faculty assistant?”

”The heel tread matches the pattern distributed to Sector Three’s alchemical apprentices three months ago. The uneven wear suggests either a structural limp or a habitual shift of weight onto the left side.”

Mirain drew a slow breath. Her crimson mantle shifted over her shoulder as she turned back toward him.

”The Mad Doctor’s network.”

”It matches the supply requisition discrepancies I flagged in last month’s inventory logs,” Valen noted. ”Sixty pounds of unrefined copper wire and twelve casks of machine oil were written off as spoiled inventory in Sector Three.”

”They’re clearing the lower vaults before the official trial inspection begins.” Her voice dropped into an icy register. ”If the Citadel marshals descend on Thursday, they’ll find empty containment rooms and pre-approved structural reports.”

”Which leaves us five days to complete the physical audit.”

Mirain’s gaze moved toward the northern passage.

”Then we—”

THUMP.

A heavy stone slab dropped into place twenty yards down the northern tunnel, sealing the path back toward the primary lift shaft.

Mirain did not startle. She turned toward the sound, her expression remaining impassive.

”The secondary perimeter gate.”

”The counterweight mechanism we heard moments ago,” Valen explained. ”It operates on a timed release once the manual lever is tripped. The main exit is now locked from the outside.”

Mirain tested the gate’s position with a glance, then returned her attention to the eastern corridor.

”Then we proceed toward Sector Three’s subterranean access. If an alchemical apprentice is operating an illegal harvesting line down here, they’ll have an egress shaft connected to their surface laboratory.”

”The eastern corridor descends at a six-degree incline,” Valen said, adjusting the strap of his lantern. ”The floor is uneven, but the supporting structure appears intact. I estimate its integrity at eighty-two percent.”

”Lead the way, Scribe.”

Valen stepped forward, his scuffed leather boots making a steady, measured thud against the damp basalt. Mirain followed two paces behind his right shoulder, her crimson mantle rustling softly in the cool draft blowing through the deep stone archways.

They walked in silence for two hundred yards.

The tunnel narrowed as they progressed. Smooth basalt blocks gave way to rough-hewn granite walls streaked with dark iron deposits. The temperature dropped steadily, and their breath formed thin clouds of white vapor in the lantern’s yellow beam.

Valen stopped.

”What is it?” Mirain asked, her hand tightening around her rapier’s hilt.

”A pressure plate.”

He lowered the lantern toward the floor.

A single granite tile, three feet wide, sat approximately two millimeters higher than the surrounding flagstones. Thin copper wires—identical to those recovered from the skeletal constructs—threaded out from its edges and disappeared into the masonry.

Mirain crouched beside him without touching the tile.

”A tripwire for heavy loads?”

”A proximity trigger for a secondary construct line.”

Valen reached into his coat pocket, withdrew his iron stylus, and knelt beside the raised tile.

”The wire is live. It carries a low-grade electrical charge intended to complete a circuit when the plate is depressed by thirty pounds of pressure.”

”Can you bypass it?”

”The mechanism is primitive.”

He inserted the flat tip of his stylus into the narrow gap between the raised tile and the surrounding stone. With a single, precise movement, he severed the thin copper strand running along the left edge.

Snap.

A faint spark of blue light flashed in the gap. A soft metallic click followed from somewhere inside the granite wall as the tension spring disengaged.

Valen withdrew the stylus.

”The circuit is broken. The path is clear.”

Mirain studied the severed wire, then raised her violet eyes toward his blindfold.

”You carry an iron stylus to bypass security arrays?”

”An iron stylus is an administrative writing tool, Representative,” Valen replied smoothly. ”Its conductive properties are simply a matter of metallurgical fact.”

Mirain released a quiet breath that sounded suspiciously like a laugh.

”You have an answer for every anomaly, Valen.”

”An anomaly is merely an uncalculated variable. Once measured, it ceases to be an anomaly.”

”And what about you?”

Mirain stepped directly into his path, forcing him to stop.

The draft from the southern shaft caught her crimson mantle and pressed the fabric against his dark wool coat. Her violet eyes searched his face with unyielding intensity.

”When do I finish measuring your variables?”

Valen stood motionless in the dim yellow light of the lantern.

”My records are fully filed in your office, Representative. You may review them at your convenience.”

”Your records state that you were born in a farming village in Sector Zero that burned to the ground ten years ago.”

Her voice softened, but the edge beneath it became sharper.

”They state that you have no living relatives, no registered martial training, and no bloodline heritage. Yet you step onto unstable flagstones without looking. You catch iron blades with your bare hands. And your left arm carries a dark-mithril suppressor capable of restraining a high-tier entity.”

”The record reflects the verified documentation.”

”The documentation is a lie.”

Mirain delivered the accusation without hesitation.

”A very thorough, very expensive lie, written by someone who understands Citadel bureaucracy better than the High Chancellor.”

Valen did not deny it.

He simply held the lantern steady between them, its yellow light casting long, sharp shadows across the rough granite walls.

”The semester trials begin in five days, Representative,” he said at last, his voice quiet and even. ”If the Mad Doctor’s agents are harvesting bloodline remnants beneath Sector Three, the safety of Cell One and the first-year cadets will be compromised before the first trial banner is raised.”

Mirain stared at him for three full seconds.

The cold wind from the southern shaft whistled through the stone arches, carrying the faint metallic tang of unrefined mana salts.

”You’re redirecting the conversation.”

”I am prioritizing the threat with the most immediate potential for casualties.”

”Of course you are.”

She stepped aside, though her suspicion had not diminished.

”We settle your ledger after we clear this floor.”

Mirain moved past him into the dark corridor ahead.

”Keep your stylus ready, Scribe. The lower vaults are coming into range.”

”Understood, Representative.”

Valen fell into step two paces behind her left shoulder.

Together, they moved deeper into the dark, echoing depths beneath the Citadel, following the faint scent of machine oil and unrefined mana salts toward the hidden machinery below Sector Three.
