Severing the Conduit

"Sorosh, look out!" Bahar screamed.

She slammed the diagnostic tablet against the side of the main injector console. A high-pitched, harmonic whine erupted from the tablet's diagnostic speaker—an uncalibrated acoustic pulse designed to ping municipal sensor arrays at maximum gain.

The sound struck the blinded enforcer like a physical blow. The crystalline growths along its skull resonated violently, throwing off its balance and causing its charging stride to veer sharply to the left.

The enforcer clipped the side of the injector casing, its maul burying itself deep into a secondary coolant pipe. A high-pressure jet of scalding steam blasted directly into the construct’s chest, melting the synthetic rubber seals around its neck and exposing the internal wire harness.

Sorosh closed the distance in two strides.

He leaped onto the enforcer's back, wrapping the brass censer's chain tightly around the exposed neck collar. With a sharp wrench of his hips, he pulled the construct's head backward, exposing the unarmored throat joint where the pneumatic lines connected to the jaw assembly.

Sorosh jammed the sharp point of his pry-spike beneath the collar ring and leaned all his weight into the lever.

Snap.

The pneumatic lines tore free in a shower of black hydraulic fluid and blue sparks. The enforcer went limp, its heavy armor collapsing beneath Sorosh as the amber glow in its eye sockets faded into dull glass.

`[CORRUPTED MUNICIPAL ENFORCER (LEVEL 7) DESTROYED]`

`[EXP EARNED: +90]`

`[CURRENT EXP: 650/600 — LEVEL UP PENDING SYSTEM RECONNECTION]`

Sorosh rolled off the chassis, his chest heaving, every muscle in his back screaming in protest. The air in the vault was thick with the stench of scorched oil, ozone, and the sharp, medicinal tang of his own burned herbs.

He pushed himself up onto one knee, wiping a streak of black grease from his brow. His hands were shaking from the kinetic strain, but his grip on the pry-spike remained absolute.

"Are you whole?" Sorosh called over the hiss of the ruptured steam pipe.

Bahar was leaning heavily against the injector housing, her face pale beneath the grime. She was clutching her left wrist, where a spray of hot coolant had blistered the skin, but she nodded sharply.

"I'm alive," she said, her voice tight. "The injector... the feed is slowing, but only because the primary pressure line ruptured when that thing hit it. It's not stopped. It's just venting raw mana into the foundation basin."

Sorosh walked over to the first fallen enforcer. Kneeling beside the shattered torso, he jammed his pry-spike into the chest plate's locking latch and levered it open with a sharp grunt.

Inside the housing, nestled amidst melted copper wiring and hardened resin, sat a cylindrical bronze module wrapped in fine cooling fins. The module was cracked along its lower rim, but its core crystal still glowed with a faint, steady amber light. Beside it, tucked into a maintenance slot, was a thin slate of crystalline memory wafer.

Sorosh reached in and wrenched both items free.

`[LOOT HARVESTED: 1x DAMAGED OVERSEER ENFORCER CORE (TIER 2)]`

`[LOOT HARVESTED: 1x QUARANTINE LOG SHARD (ENCRYPTED)]`

He pocketed the core and the wafer, his pragmatic mind already calculating their salvage value. A damaged enforcer core was worth at least seventy chits to an unlicensed mechanic in the bazaar, and the log shard might give Bahar the proof she needed to blow Tymur's operation wide open.

"We need to get to the hoist," Bahar said, pushing away from the console and staring up into the dark vertical shaft where Tymur had vanished. "If we take the emergency ladder beside the hoist rails, we can reach Platform 1 before he purges the concourse records."

Before Sorosh could answer, a deep, grinding thud echoed through the bedrock beneath their boots.

Overhead, at the mouth of the maintenance shaft, a massive iron barrier began to slide into place. It wasn't a standard security grate; it was a four-inch-thick municipal blast door, reinforced with heavy interlocking teeth and stamped with the yellow quarantine sigil of the Overseers.

The door slammed shut with a concussive boom that sent a shower of concrete dust raining down upon their heads.

A second later, the massive hydraulic locking bolts engaged with four distinct, rhythmic thuds.

Clang. Clang. Clang. Clang.

The elevator shaft was completely sealed.

A single, low-powered emergency beacon flared to life on the wall beside the sealed blast door, casting a sickly red light across the vault. Below the light, a primitive analog pressure dial hissed softly, its needle pegged firmly into the red hazard zone.

`[MUNICIPAL ISOLATION PROTOCOL COMPLETE]`

`[CONTAINMENT CHAMBER: SUB-LEVEL 3 SEALED]`

`[PURGE CYCLE: ARMED - COUNTDOWN SUSPENDED PENDING ADMINISTRATIVE CLEARANCE]`

Sorosh walked slowly to the base of the elevator shaft, looking up at the seamless slab of reinforced iron. He tapped the surface with the butt of his pry-spike. The sound was dull, dense, and utterly immovable.

"No ladder," Sorosh said flatly. "Tymur engaged the physical quarantine seal from the upper terminal."

Bahar stared at the locked blast door, her breath coming in shallow, ragged gasps. "The isolation protocol... Sorosh, Sub-level 3 doesn't have an external ventilation exhaust. When they seal a containment zone under Directive 44, the air recirculators shut down to prevent airborne spore spread. In less than two hours, the unrefined mana venting from that broken pipe will displace every cubic foot of breathable oxygen in this vault."

"It's remarkable," Sorosh muttered, running his fingers across the cold iron plate. "The municipal government can't keep the market clean, can't fix a broken gate latch on Platform 4, and takes six weeks to approve an apprentice surveyor's permit. But the moment they need to lock two people into an airtight tomb, the engineering works with flawless, hundred-percent efficiency."

Bahar didn't laugh, though the tight lines around her mouth relaxed by a fraction of an inch. "That isn't comforting."

"It isn't meant to be," Sorosh said.

He turned his back on the sealed door and walked toward the center of the chamber, where Strut 09-Prime rose into the vaulted ceiling.

The massive support pillar was in terrible shape. The raw mana that Tymur had injected into its core was continuing to react with the load-bearing alloy. Long, spiderwebbing veins of crystalline amber were spreading outward from the foundation plate, climbing five paces up the pillar's flanks. Every few seconds, a sharp tink echoed through the steel as another internal structural rivet sheared under the unnatural expansion of the stone.

"Look at the lock," Bahar said, her voice trembling as she joined him near the hoist base. She pointed toward the heavy locking housing set into the wall beside the blast door. The mechanism was encased in a thick bronze casing, sealed with four magnetic tension bolts and a physical harmonic tumbler. "It's an Overseer Class-4 blast seal. Even if I had my diagnostic slate at full power, it takes a Level 3 administrative decryption cipher to cycle the hydraulic release."

"Your slate doesn't have full power," Sorosh observed, his tone dry and entirely devoid of panic. "And the System currently thinks we don't exist."

"Then we're trapped. We can't break through four inches of reinforced steel with an iron pry-spike."

Sorosh crouched near the pool of weeping amber fluid at the base of the broken injector pipe. He reached into his belt pouch and pulled out the Intact Overseer Diagnostic Core they had salvaged from the baggage drone in Chapter 3, turning the heavy, polished bronze cylinder over in his hand. Then he looked at the Damaged Enforcer Core he had just ripped from the guard's chassis.

"The System built this door to keep things in," Sorosh said softly, his thumb tracing the fine sensory runes etched into the bronze casing of his censer. "It runs on standard municipal harmonic frequencies. When the Overseers want to open it, they don't use magic—they send a coded electrical frequency through the lock's copper grounding pins."

Bahar frowned, wiping the sweat from her eyes. "Yes. A frequency generated by an Overseer diagnostic core. But our core is encrypted, and without a terminal interface to run the decryption algorithm—"

"I don't need an algorithm," Sorosh said. He opened the top latch of his censer, setting the perforated lid aside. Inside, the bed of glowing charcoal pulsed with a steady, crimson heat. "I just need to know what note the copper wants to sing."

He laid the two cores side by side on the concrete apron, next to his pry-spike and his pouches of crushed herbs.

"That intact Type-8 core is the only evidence that clears me with the Directorate," Bahar said, her voice catching as she realized where his hands were moving. "If you burn its firmware to crack that door, there's no going back to the Overseers. We're both registered outlaws."

Sorosh struck the pry-spike against the bronze housing, cracking the casing of the diagnostic core with a sharp, resonant snap. He didn't hesitate. He wedged the fractured core into the censer's crucible alongside the pinch of dry sulfur, setting the iron tool down between them.

"We were outlaws the second Tymur dropped that blast door," Sorosh said, meeting her gaze across the glowing embers. "The Overseers aren't coming to clear your name, Auditor. From here on, we clear it ourselves."
