The Strategic Reserve

"The gray slime," Vahram said, his mind tracking back through decades of habitat maintenance logs. "Where does the Sub-Gallery Four return line originate?"

"It doesn't pull from the mines," Farzan said. "It's the primary intake loop from the deep cryogenic vaults beneath the amphitheater. The lines that feed the central scrubbers."

Cryogenic Vault 01-Alpha, Vahram thought. The strategic reserve. If the bio-sludge was growing at the intake, the habitat's entire oxygen reserve was rotting from the inside out. Navran was fighting a silent war against an invisible rot, and he was willing to kill anyone who caught a glimpse of the infection.

"Vahram," Farzan muttered, his eyes darting nervously toward the far end of the penal corridor. "Even if you know this, the Tribunal scribes won't overturn Navran's seal based on my word. They'll say I'm an indentured felon lying to dodge the vacuum shifts."

"They will," Vahram agreed. "Which is why we aren't asking the scribes to believe your word. We are forcing them to admit the physical routing records into the Ring record. But to do that, I need access to the lower amphitheater junction before the bout starts. Navran has locked down Vault C and the arena understructure with administrative security seals."

Farzan reached slowly down to the heel of his left boot. With careful, practiced movements honed by years of smuggling mining tokens past sector guards, he twisted the vulcanized rubber tread. The heel popped open on a concealed brass hinge.

From the hollow recess, Farzan extracted a slim, rectangular wafer of etched copper—an unlogged master bypass key, stamped with the four-prong insignia of the original habitat construction guild.

"My uncle was a master pipe-fitter when they laid the keel of Sector Three," Farzan said, keeping his hands low beneath the bench. "This is an analog conduit override. It doesn't ping the central mainframe when you cycle an emergency hatch. It mechanically drops the magnetic solenoids on any maintenance sluice between the lower vaults and the arena sub-floor."

Farzan slid the wafer toward the narrow specimen transfer trough at the base of the quartz partition—a heavy steel revolving drum used by guards to pass nutrient paste and water rations to the prisoners.

"Take it," Farzan whispered. "If Riza wins that bout, the verdict clears my record automatically. If he loses... well, at least Jahan will make it quick for him. The vacuum won't be quick for me."

Vahram reached for the revolving drum, preparing to rotate the brass handle to draw the key through the sealed partition.

Suddenly, a high-pitched electronic warble cut through the quiet hum of the crawlway.

Along the ceiling of the penal corridor, the amber standby lamps flashed violently to brilliant cyan. A synthetic voice, flat and unhurried, echoed across the intercom loop:

Attention all personnel. Sector Two atmospheric audit in progress. Article Fourteen compliance sweep initiated by order of the Magistrate. Pressure barriers closing in sixty seconds. All unauthorized personnel in transit corridors will be subject to immediate decompression quarantine.

"Damn it," Farzan gasped, his body stiffening. "Barzin's quota sweeps. The wardens are sealing the entire sub-tier to measure the pressure drop!"

Vahram seized the revolving drum's handle, spun it one hundred and eighty degrees, and snatched the copper bypass wafer from the chamber. He shoved the key into his suit's thigh pouch and zipped the seal shut.

Through the observation glass, the heavy steel security grates at the end of the penal corridor began sliding downward with a deafening hydraulic shriek.

"Get back on the bench, Farzan," Vahram commanded. "Close your eyes and breathe slow. Do not look at this glass."

Farzan scrambled back onto the steel bench, pulled his knees to his chest, and buried his face in his regolith-stained arms, adopting the passive posture of a sleeping convict.

Vahram spun around and dropped into the service trench.

Behind him, thirty meters down the narrow access tunnel, the primary pneumatic seal was already descending—a four-inch slab of reinforced steel dropping like a guillotine into the floor groove. If that door sealed, the crawlway would become an airtight dead end, and the automated purge system would vent the entire volume into the vacuum exhaust to verify seal integrity.

He could not make it back to the stamp mill crawlway. The distance was too great, his suit's auxiliary oxygen was dropping past forty percent, and his scarred right knee would not survive a full-momentum sprint across the grated deck.

He had one way out: down.

Directly beneath his boots lay the emergency basalt slag chute—a seventy-meter unpressurized vertical shaft cut through the solid lunar bedrock, designed to drop crushed rock aggregate directly into the high-speed sluices of the lower smelting works. A heavy, hand-cranked blast hatch secured the chute entrance.

Vahram jammed the notched iron pry-bar beneath the dog-latch of the slag hatch. He threw his entire body weight onto the lever, using the mechanical advantage to overcome the rusted vacuum seal.

Crack.

The dog-latch sheared with a sharp metallic snap. The hatch popped open three centimeters, hissing as the residual forty kilopascals of tunnel air rushed into the unpressurized void of the chute.

Vahram ripped the hatch wide open, revealing a sheer, pitch-black abyss falling straight into the dark belly of Sector Two. From deep within the shaft came the roaring, abrasive howl of thousands of tons of basalt gravel rushing through the primary sorting screens.

He checked his wrist display: twenty seconds before the corridor doors sealed.

Vahram clamped the iron pry-bar into his right gauntlet, tucked his elbows tight against his ribs, and dropped boots-first into the black throat of the chute.

The fall was low-gravity—one-sixth of Earth standard—but in a vertical shaft, sixty meters of free fall was more than enough to turn human bones to powder upon impact.

Wind screamed past his helmet visor as the draft of the exhaust fans pulled him downward. The rough basalt walls of the chute blurred past in the dark, jagged and unpolished, scored with deep rifling grooves from decades of abrasive rock flow.

Ten meters. Twenty meters.

Vahram did not panic. He waited until his falling speed reached twelve meters per second, then slammed the flat of his heavy, armored shin-guards against the opposing walls of the shaft, wedging his body into a controlled friction brake. At the same time, he drove the notched tip of his iron pry-bar into the rock wall.

The iron bit into the basalt with a shower of brilliant, white-hot sparks that illuminated the dark chute in violent strobes. The screech of metal tearing into stone reverberated straight up his arm, jarring his teeth and ripping at the torn ligaments of his right shoulder.

Screeech—crack.

His descent slowed. Thirty meters. Forty meters.

The friction tore at his gauntlets, the heat transferring through the thermal insulation until his palms burned, but his speed bled away from a lethal dive to a survivable slide.

Fifty meters down, the vertical chute curved sharply into a forty-five-degree basalt slide, dumping into the lower sorting hopper.

Vahram pulled his pry-bar clear, tucked his chin to his chest, and struck the angled stone floor at five meters per second. He rolled instantly, absorbing the momentum across his armored shoulder, his backplate, and his thighs, sliding fifteen meters through a sea of crushed anorthosite gravel before coming to a halt against a rubberized deflector baffle.

He lay still for three seconds in the dark, surrounded by the deafening roar of the gravel screens.

The air around him was cold, thin, and filled with floating silicate dust that sparkled like diamonds in the faint glow of his suit telemetry. He checked his heads-up display: auxiliary oxygen at twenty-eight percent. Structural integrity of the suit: nominal. Right knee: aching fiercely, but the joint was intact.

He reached down to his thigh pouch. The etched copper bypass wafer was still there, cold and solid against his fingers.

Vahram-dar pushed himself up from the gravel heap, brushed the gray lunar dust from his visor, and looked toward the low-clearance transit tunnels leading to the central amphitheater.

He had the truth behind the blowout. He had the physical key to the lower vaults.

Now, he had thirty-nine hours to teach Riza-ran how to kill a man who could not run out of breath.
