The next morning…
I awakened to the soft glow of the sanctuary's light and the smell of something vaguely resembling coffee brewing on a hotplate. Serraphine was already at her workbench, data pads lit up around her. She glanced over as I stirred.
"You were out for twelve hours," she stated without preamble. "The patrols have moved on from this sector, but they've increased checkpoints near the Obsidian Spire's lower access tunnels." She took a sip from a stained mug. "If we're going to look for answers about your mentor, or my files, or these… 'real animals'… we need to move carefully."
She turned to face me fully.
"I'm not sure where to start; I think you have a better handle on what's going on at the moment, so I'll follow your lead." I replied.
A flicker of surprise, followed by clear approval, crossed Serraphine's features. She wasn't expecting me to defer to her so readily. She gave a sharp, decisive nod.
"Good then we start with the one thing CoreBorn can't fully control: the trash." She gestured to a pile of worn, patched-up worker's coveralls and a grimy, featureless helmet on a nearby crate. "Get changed. We're going to the Geothermal Conduit Access Point, sector Gamma-7."
She stood and began gathering her own nondescript gear.
"It's a maintenance sector for the old city power grid, buried deep. The data-streams are thin there, the surveillance is patchy, and the Flux… it's stronger. I've traced some of my encrypted file fragments back to data-caches dumped there." She paused, looking at me seriously. "It's also where the 'whispers' started for me. The ones that don't come from comms."
She handed me the coveralls. They smelled of grease and ozone.
"We'll pose as sanitation engineers running a diagnostic. It won't hold up to a deep scan, but it should get us past the automated patrols." She fastened a tool belt around her waist. "Once we're in, your job is to listen. Tell me if you feel anything… strange. A pull, a hum, a memory that isn't yours. That will be our guide."
She checked the charge on a stun-prod tucked into her belt- a far cry from the enforcer's gear, but effective at close range.
"Ready to go digging in the city's guts?"
"Ready as I'll ever be." I responded.
Serraphine gave a final, appraising look around her sanctuary before leading me out of the same hidden door I entered. The journey through the service tunnels was a tense, silent affair. She moved with the ingrained knowledge of a lifetime spent in these shadows, pausing at the intersections to listen, using hand signals to direct us down alternative paths when the distant, mechanical cadence of an enforcer patrol echoed too close.
After nearly an hour of navigating the city's underbelly, we arrived at a massive, rust-streaked blast door marked with faded hazard symbols and the designation GCAP » 7 . Serraphine produced a forged key card from her sleeve. The scanner flashed red for a heart-stopping second before she adjusted the card's angle and it beeped green. The door groaned open just wide enough for us to slip through.
The air that hit us was thick, hot, and heavy with the smell of sulphur and ozone. We stood on a grated metal catwalk overlooking a cavernous space. Below, immense geothermal pipes, ancient and crusted with mineral deposits, snaked through the darkness, thrumming with a deep, resonant power. Flickering emergency lights cast long, dancing shadows. The Flux here was not a faint hum; it was a palpable pressure in the air, a vibrating energy that prickled against my skin and made the green strands of my hair glow more brightly.
This was it. This was one of the sources.
Serraphine pointed down to the cavern floor, a maze of pipes and machinery some fifty feet below. "The main access panel for this sector's data-relay is down there. That's our target." She attached a climbing harness to the catwalk railing. "It's a straight drop. I'll go first."
Just as she prepared to rappel down, a low, guttural growl rumbled from the shadows directly beneath us. It was not mechanical. It was organic, predatory, and deeply wrong.
From the darkness between two massive pipes, a creature lurched into the dim light. It had the general shape of a large canine, but its form was malformed, its flesh seeming to ripple and bubble like tar. Jagged spurs of rusted metal and broken conduit protruded from its back, and its eyes glow with a sickly orange light that mirrored the emergency beacons. It sniffed the air, its head swivelling until its gaze locks directly onto me.
Then with a sudden, sickening lurch of movement, it launched itself upwards. Its sickly orange eyes, burning with predatory hunger, remained locked onto me. Before I could even fully react, the monstrosity was upon me, a whirlwind of metal and sinew. Its jagged maw clamped down, tearing through my reinforced jacket and raking my side. A wave of nausea, a potent poison, threatened to engulf me, but my innate resilience fought it back, an internal fire warding off the venom. As the creature recoiled, I lashed out with a burst of infernal energy, a Hellish Rebuke, searing the beast's hide with crackling flames.
But the creature was relentless. It lunged again, its movements surprisingly swift for something so grotesque. Another bite, another surge of poison that I once again shrugged off, and another retaliatory burst of fire from my very essence scorched its hide, leaving a faint smell of ozone and burnt oil in the air. Serraphine, ever vigilant, sprang into action. Her movements were fluid and precise. With a sharp, practised thrust, her blade found a vulnerable seam in the creature's armoured plating, piercing its flesh and eliciting a pained, metallic yelp.
Yet even as Serraphine drew first blood, I saw something in the creature's frenzied eyes - not just malice, but a desperate, primal confusion. I seized the moment, my hand extending, not with a spell of destruction, but of calming influence. A shimmering pulse of arcane energy, a whisper of command, flowed from me. The creature, mid-lunge, faltered. Its sickly orange eyes blinked, the predatory fire dimming, replaced by an unsettling, almost docile curiosity. The snarl died in its throat, its posture relaxing, its techno-organic form shifting from aggression to a wary, but no longer hostile, stillness.
The sudden shift was palpable. The air, thick with the scent of ozone and fear, cleared. The battle which had exploded with such ferocity simply ceased. I, though my side ached where the creature's fangs had connected, and my jacket was torn, stood firm, my breath coming a little heavily. The malformed canine, its hide still smoking faintly from my hellish retorts and bearing a fresh, bleeding wound from Serraphine's blade, now regarded us with an unnerving, almost friendly, gaze. The immediate threat was gone, replaced by a new, unforeseen companion in the echoing, pipe-filled depths of Gamma-7.
The sudden cessation of hostilities left an eerie quiet in the cavern, broken only by the deep, resonant thrum of the geothermal pipes and the distant drip of condensation. The air, still thick with the acrid scent of ozone and burnt oil, slowly began to clear.
My side ached where its fangs tore through my jacket, a sharp reminder of the danger we were just in. Serraphine, her stun-prod still clutched in her hand, slowly lowered it, her gaze fixed on the now docile beast. Her blue scales seemed to ripple slightly in the dim, flickering light as she processed the impossible turn of events.
"I… I've never seen anything like that," she whispered, her voice barely audible above the pipe's hum." These things usually just attack until they're destroyed. You… you calmed it."
The creature whimpered softly, nudging its head towards me, a strange combination of rusted metal and organic flesh.
The immediate threat had paused, but a new, bizarre element had entered our journey into Undercity's hidden depths. My jacket was torn and my body protested the recent trauma.
I took a moment to press my hand to the wound on my side, the faint green glow of my hair intensifying as I channelled a whisper of the Flux. The torn flesh knitted together closing the worst of the wound, the ache receding to a dull throb.
Then I focused my will, extending a thread of ancient understanding towards the creature. The world of sound shifted subtly. The hum of the pipes became a deep, resonant song, the drip of water a rhythmic percussion as I spoke directly to the creature as if it could understand me, "Would you like to join us, I'll even give you a name. How does Rex sound." And the creature's soft whine resolved into a voice in my mind - a chorus of confused overlapping sensations.
"...bright-green-man… hurt? No… safe? Smell like deep-earth-warmth and old-sky-thunder… pain in my side…sharp-blue-scale-woman caused pain… but bright-green-man took away the anger-noise in my head… the constant screeching-light…"
It tilts its head, its rusted plates grinding softly. "Rex? Is that a sound? It is… solid. A good sound. Better than 'scrap-beast' or 'aberrant target.' Yes. I am Rex."
