“Damn it,” Pela whispered, her voice barely audible above the new, ominous hum of the struggling generator. “It’s already begun.” The needle on the master dial kept dropping, ticking down degree by degree. The lights, which had brightened momentarily with the airlock’s sealing, now flickered, casting long, dancing shadows across the steel plating of the command center. Outside the reinforced glass, Maris watched her through narrowed eyes, waiting for the logistical mask to slip back on. “Explain,” Maris commanded, her voice cutting through the generator’s dying gasp, devoid of her usual condescension, replaced by a brittle edge of urgency. “What has begun?” Pela didn’t look away from the gauge. “Sabotage. An intruder bypassed the inner seals and hit the primary core.” She snatched a handset off the dock. “Joren, secure the comms array. Kelso, Goran, Delia – you three stay put in the common room. Do not, under any circumstances, leave that space. Rusk, you’re with me. Maris, you too. We’re going to the thermal manifold.” Maris raised an eyebrow, a flicker of something almost like grudging respect in her eyes. “And your newfound guests? Are they to be trusted with, what, the fate of the world?” “They just survived an encounter with the same things that want to turn *this* place into a giant freezer,” Pela retorted, finally turning, her eyes glinting with a cold resolve Maris had not seen before. “They’ll be motivated. Besides, the common room’s locked down tight.” She handed Rusk a heavy-duty portable light from a wall rack. “You’ve seen more compromised systems than the rest of us combined, Tarin. Your eyes for a weak point are… unparalleled.” Rusk grunted, taking the light. “I prefer ‘finely tuned.’ And less complimentary descriptions are often just as accurate.” He gave a cynical glance at the rapidly dimming lights. “If this is a ‘weak point,’ Vaskan, it’s a vital one.” The spiral stair to the lower utility deck plunged straight into the lighthouse’s churning gut. The air grew thick with the smell of ozone and superheated coolant, the clamor of the struggling generators amplifying with every step. The room itself was a labyrinth of insulated pipes, glowing conduits, and massive, shuddering pressure tanks. The primary core, a colossal sphere of pulsating crimson, sat at its heart, its output dimming to a sickly amber. “The bypass array,” Pela said, pointing a gloved finger at the ventilation shafts snaking into the core’s housing. “If the core’s output is dropping this fast, the internal regulators are being throttled. A saboteur crawled in without tripping the pressure seals. The vents are the only route.” Maris eyed the narrow, grime-caked duct mouth. “You mean *we* are going in there? Vaskan, those shafts are barely wide enough for a service drone. They haven’t been cleaned since the Oskola Shipping Authority repurposed this place for coastal defense drills.” “And yet, here we are,” Pela said, already unlatching a vent cover. A cloud of ancient dust and a faint, metallic odor wafted out. “Rusk, you keep watch here. If anyone tries to enter, you sound the alarm. If anyone tries to leave, you… convince them otherwise.” Her eyes were on Rusk, a silent challenge passing between them. He met her gaze without flinching, a small, knowing smirk playing on his lips. Pela grabbed a coil of emergency light-wire and handed one end to Maris. “Stay close. If it gets too tight, pull the cord once. If you find anything, pull it twice.” She gestured to the open vent. “Ladies first.” Maris exhaled sharply and wedged her shoulders into the steel hatch. Her usually impeccable work jumpsuit snagged on a protruding rivet, leaving a streak of oil across the pristine fabric. Pela followed, the confined space immediately oppressive. The metal groaned under their weight, the darkness absolute save for the beam of Pela’s headlamp and the faint glow from the light-wire Maris held. Dust motes danced in the limited illumination, thick and suffocating. The air was stale, laced with the metallic tang of old machinery and something else – a faint, acrid scent that Pela couldn’t quite place. “This entire plan,” Maris’s voice echoed, thin and strained, from ahead, “it relies on… *this*? Crawling through rat holes?” “Every logistical solution has its less glamorous elements, Corven,” Pela grunted, shunting herself forward using her elbows. “Besides, if the saboteur could get through, so can we. They wouldn’t make it easy for themselves to escape, either.” They crawled forward inch by inch, the hum of the failing core grating through the sheet metal beneath them. Pela’s hands, trained for intricate panel work and delicate circuit tracing, scraped against rough metal. Her bright yellow work vest, a cheerful anomaly in the gloom, was quickly acquiring new stains. Ten minutes in, Pela’s lamp caught raw sheared metal. A bypass cable, thick as her wrist, had been neatly severed, the copper wiring splayed like a blossoming flower of destruction. “There,” Pela murmured, steadying her breath against the iron floor. She reached for it, her fingers brushing the clean, sharp edge of the cut. This wasn't corrosion or a stress fracture. This was surgical. “It’s a clean cut. Professional grade. And fresh. The coolant hasn’t even fully crystallized on the exposed core yet.” Maris wriggled closer, her own light beam joining Pela’s. She inspected the sheared bundle with a squint. “I told you, Vaskan. Humanity is its own worst predator. You invite them in, they gnaw at your foundations.” Her voice was low, but the usual edge of rivalry was gone, replaced by a shared, chilling understanding. “This wasn’t the raiders. This was an insider. A turncoat who knows the duct layout and knew where to slice without tripping an immediate shutdown.” Pela leaned back on her heels, recognizing the scorch of a carbide shears. Her reflex to smile through friction had blindfolded her; she had balanced fuel reserves and cold rations while ignoring the viper standing beside her desk. Just then, a voice, warm and solicitous, echoed up the shaft from the manifold room. “Pela? Maris? Everything alright up there? I brought coffee. Black for you, Pela, and… is it a triple-shot synth-mocha for you, Maris? Thought you might need a kick.” It was Joren. His head poked into the duct mouth, balancing a mug in each hand. His smile was wide, earnest. “The comms array is secure, boss. No external interference. Maybe the raiders have some kind of remote jammer out there, hitting the core? They’ve got some nasty tech, I hear.” Pela shifted her gaze between Joren’s solicitous grin and the severed copper line. “Joren, stay out of the shaft. Maris and I have work to do.” As Pela began to mentally map out a temporary reroute, Rusk’s voice cut in, devoid of its usual casual sarcasm. “A remote jammer wouldn’t shear heavy copper, Hest,” Rusk called from below. “A saboteur squeezed in here with shears.” “They knew every tap point,” Rusk added. “A ghost in the works, Vaskan. You’re harboring your own executioner.” Before Pela could respond, before Maris could offer a cutting remark, a deafening *CRUMP* reverberated through the entire lighthouse. The ground beneath them lurched violently, sending a shower of dust and small debris cascading down the vents. A low, guttural roar followed, a sound of tearing metal and splintering ice. Then another *CRUMP*, closer this time, shaking the very foundations of the Aegis Beacon. “What was that?!” Joren yelped, nearly dropping the coffee. Rusk was already scrambling back toward the central board. “That wasn’t a jammer. That was an ice-borer. And it sounds like it just found purchase.” Across the main panel, the exterior perimeter map of interlocking shipping containers flashed crimson. A section of the northern wall, near the cliff face, had just gone offline. Breached. The raiders were inside the outer shell. And the core’s output continued to bleed out.
