Kaven snatched the satchel, his jaw aching from how hard he bit down. He trailed her out into the corridor, where the alarm horns were screaming in full fury, echoing down the bare stone stairs toward the boiling darkness below.
The descent dropped straight toward the city's churning guts. The lower subterranean levels were usually a network of humming manifolds and disciplined technicians, a place of harnessed steam. Now, it was a maw of noise and flare. The air thickened with an acrid mineral tang, an ozone-laced stench that made his eyes water. Emergency lights strobed in fractured arcs through the gloom, painting the sweating stone walls in frantic reds and sickly greens.
From the depths, a guttural thrum rattled the steel grating. It was the howl of an ungrounded surge rattling its casing. Kaven hauled the heavy satchel, the cooling coils clattering within, his shoulder aching against the strap. He stumbled, catching himself on a greasy handrail, drawn toward the blinding fissure ahead. It was a rent in the primary retaining bulkhead where a high-pressure line had split. Molten fuel, normally locked under vacuum, now writhed across the tiles, spraying incandescent droplets that vaporized on contact with the stone.
“Stay close,” Zorina said, her voice dry over the din. She didn’t look back. Her dark cloak drifted behind her, a sharp shadow against the infernal flare. She kept a steady cadence across the slick floor plates. Technicians in vulcanized rubber suits scrambled away from the breach, slipping in pooled brine. A full discharge would leave nothing behind except a grease stain on masonry.
Zorina stopped at the edge of the safety perimeter, unfurling a reinforced lead cloth from her pack. “Pressure valve, second chamber. Get it sealed, then install the coils.” She pointed with a gloved hand, the movement sharp and precise. “I’ll draw the surge.”
Kaven stared at the roiling slag, then at her. “Draw the surge? You’ll be annihilated!”
She didn’t answer. Instead, she threw off her outer cloak, revealing a suit of dense, insulated weave. Her gloved hands pulled three brass governing chokes from her utility belt, locking them to strategic anchors along the bulkhead frame with metallic snaps. Then, she raised her palms toward the breach.
The air crackled. The boiling discharge stopped spraying and gathered into a single dense ribbon. Violet and dull orange light coiled around her outstretched fingers. Her frame shimmered behind a shimmer of thermal exhaust. The runaway pressure bent toward her, drawn into a steady stream that spiraled around her forearms without igniting her sleeves.
The roar died down to an iron drone as she trapped the charge inside an unseen pocket. This was nothing like the measured formulas taught in lecture halls, no delicate dance of clockwork and exhaust tracks. It was brute, bare-handed wrestling with raw fuel.
“Volkov! Now!” Her voice cracked. The discharge curled around her wrists, the surrounding air warping like glass in a blast furnace. A fine tremor shook her forearms.
Kaven dropped to one knee, yanking out the heavy spanner and the bucket of resin. He levered the warped governor housing into place, the heat boiling off the feeder tube blistering his knuckles through his sleeves. He smeared the thick compound into the seams, bolting the twin cooling jackets around the neck of the pipe. It was ugly, rushed work, far removed from the clean drafting benches of his old laboratory, but the seals locked.
As the last coil clamped shut, Zorina gasped. The hovering column collapsed inward, snapping like a bullwhip with a dry *CRACK*. The split pipe fused under a burst of white heat, leaving behind a black, bubbling scab across the seam. The chamber settled into silence, choked with burnt zinc and pulverized lime.
The horns on the distant catwalks wound down into a sputtering groan.
“Quite the spectacle, Saint Rostova.”
The smooth, genial voice cut through the ringing in Kaven’s ears. Prefect Sidorov, accompanied by two impeccably dressed aides, strode into the still-smoldering zone. His smile was as immaculate as his uniform, a beacon of composure amidst the wreckage. “Necessary force, I presume?”
Zorina did not turn. “The main line burst. The boundary failed.”
Sidorov chuckled, a soft, pleasant sound. He stooped beside the cooling pipe, his fingertips tapping the fresh slag. “Indeed. A devastating display. Such a pity.” He reached into a scatter of blackened rubble and lifted a corroded brass valve, its casing cracked across the threads. “From the primary intake line, it seems.”
Kaven scowled. He had just sealed the feeder; the primary intake sat thirty yards down the gallery, intact. Sidorov rotated the brass scrap in his manicured fingers. “Poor craftsmanship, wouldn’t you say, Volkov? Looks like standard stock from Novus Forgeworks. Always cutting corners. A shame they held the contract for the lower manifold upgrades. This will make quite a scandal.”
The Prefect had brought the piece in his pocket. It was a targeted smear against Novus Forgeworks, whose board sat on the city council's finance committee. The municipal failures were not system fatigue; they were manufactured leverage.
Zorina finally turned, her veil still obscuring her expression, but her posture was rigid. “The situation is resolved, Prefect. We should begin full systems diagnostics.”
“Of course, of course.” Sidorov waved a dismissive hand. “Leave the clean-up to my men. You’ve done splendidly, Saint Rostova. As always, you save us from ourselves.” His smile didn’t reach his eyes. “Volkov, ensure Saint Rostova’s reports are filed with utmost precision. We wouldn’t want any… misunderstandings.”
Kaven felt a cold knot form in his stomach. He was a pawn, dragged into a game far more dangerous than he’d imagined.
Later, back in Zorina’s second-floor office, the smell of scorched sulfur still clung to Kaven's wool collar. She pulled off her gloves. Her skin showed waxy and bloodless under the gas lamps. Hunched over the scarred mahogany desk, she cleaned the lead chokes with an oiled rag, her pace mechanical and slow.
Suddenly, a harsh, racking cough tore through her. It was a dry, rasping sound that seemed to tear at her throat. She clutched her chest, her body convulsing. Kaven froze, startled. The cough deepened, growing more violent. She pressed a hand to her mouth, stifling the sound. When she lowered it, Kaven saw it – a fleck of blackened blood, stark against the pale, calloused skin of her palm. It was gone in an instant, wiped away with a practiced swiftness he almost missed, but not quite. Her movements became even more deliberate, her back stiffening, as if she knew she had been observed. She didn't look at him.
Kaven leaned against the filing cabinet, turning the image of that soot-blackened smear in his head. Wielding that much raw charge tore through flesh, yet she hid the cost behind her scarf like an embarrassed clerk.
The chime of the office door startled them both. Dragomir Orlov leaned casually against the frame, a smirk playing on his lips. He wore his usual impeccable Institute uniform, a stark contrast to Kaven’s grime-streaked clothes. “Volkov. A moment of your time?”
Kaven glanced at Zorina, who remained frozen over her desk, her back to them. “What do you want, Orlov?”
Dragomir stepped forward, his eyes bright with familiar calculation. “Just a friendly word between colleagues. You look like you’ve been dragged through a boiler flue, old friend. Perhaps it’s time we discussed an alternative route back to our appointments.” He dropped his voice, leaning past Kaven to look toward the desk. “I found curious gaps in Rostova’s requisitions. Proof that she’s systematically skimming components to divert elsewhere. What do you say? A partnership? Expose our dear Saint, and we both climb out of this pit.”
