15. Cassia #2
I stand up from the crate, ignoring the brief throb in my temples as Rhykor’s hand immediately clamps around my elbow to balance me.
"There's a decommissioned mechanical vault beneath the primary lift," I state, looking between them.
"The walls are lead-lined to prevent radiation leaks from the old engines. Nothing transmits through that steel."
Rhykor takes point, angling his body to shield us from view as we guide Junia out of the main area. Directing his two remaining loyal enforcers to guard the bay entrance, he gives them strict instructions to maintain the triage line until we return.
We slip down a narrow, ladder-lined conduit that smells of old grease and stagnant water.
The small mechanical vault comprises a square box of tarnished iron plates completely cut off from the other parts of the facility.
The only illumination comes from the pale blue backlight of Junia’s data-pad as she slams the heavy vault door shut, throwing the mechanical seal into place with a resounding clang.
"Look at this," Junia commands, slapping the data-pad onto a rusty workbench.
Her fingers fly across the glass interface, pulling up a series of complex schematic overlays that ripple across the screen.
"When the main power grid went dark last night, the security blocks on the sub-level infrastructure experienced a three-second latency loop.
I managed to drop a tracking siphon into the Legion data-vault before the firewalls were restored. "
I lean forward, squinting at the shifting red lines on the map. The layout shows the geometric grid of District Seventeen, but deep within the familiar streets and markets lies a massive, undocumented labyrinth of structural rings extending miles into the planet's crust.
"Those aren't standard drainage pipes," I note, tracing the perimeter of the lowest ring with my index finger.
"Data from the network traces active hubs to this exact location, right beneath our feet, using the bedrock of District Seventeen as a foundation," Junia explains, her teeth clicking in frustration.
"Both the sickness in the clinic and the enforcers' erratic behavior are symptomatic of that proximity.
Essentially, this entire district is acting as a physical buffer for a machine entity growing beneath the civilians. "
Rhykor steps up to the workbench, his arm brushing against my shoulder as he peers down at the layout. A heavy rumbling starts in his chest, a sound that vibrates through the metal table supporting our hands.
“The Trident Alliance constructed this sector over a century ago," Rhykor says, his posture hardening into a military stance. "My high command verified the lower foundations as solid granite prior to the occupation. This grid should not exist."
"Then your high command lied to you," Junia declares, tapping a flashing node at the very center of the underground network. "Or someone built this right under their noses using local labor. Look at the power draw. Even during this total blackout, this specific subterranean core is drinking seventy percent of the reserve thermal energy from the district’s deep wells. It’s a self-sustaining hive. "
The realization hits me with sudden clarity.
"We are sitting on top of the weapon," I state softly.
"The diagnostic logs show a steady escalation in local network activity," Junia whispers, pointing to a spiking telemetry line on the glass interface.
"The automated systems and local network nodes are siphoning power from our grid to reinforce the subterranean layers.
They are expanding their reach by the hour. "
Rhykor's hand closes over the side of the data-pad, his grip tightening until the casing groans.
His focus remains on the schematic, his entire frame going unnaturally rigid as he processes the reality of the threat.
"An immediate strike would be reckless," he asserts, turning his head to glimpse at me. “Structural maps of these sub-layers are unavailable, and you’re still recovering. We gather more intel on their patrol rotations, then we move.”
"He’s right," Junia agrees, uploading the tracking metrics to a hidden local drive. "I need to secure these encryption keys anyway. Going in blind right now is a suicide run. We pull back to keep the refugees stable while planning the infiltration once we have a clear path."
I offer a tight affirmation, the logic overriding my surge of adrenaline. "Then we focus on the bay for tonight. Let's get these survivors through the dark first."
The heavy door of the mechanical vault screeches against the iron frame as we slide it open, transitioning from the cold, insulated quiet of the underground back into the dense atmosphere of the freight bay.
The day continues in a blur of focused labor as we return to our tasks, tending to the endless line of arrivals.
By the time the midnight hours finally settle over District Seventeen, the temperature drops further, turning the breath of the huddling survivors into pale plumes of mist. Rhykor guides me back toward our central station with an unyielding grip on my forearm, the rough fabric of his vest cold against my sleeve while his body heat spills outward like a furnace.
He forces me down onto a thick pallet of overlapping wool blankets we managed to arrange near the functioning thermal blocks. I start to protest, my hands reaching for an unrolled spool of clean linen, but he anchors his large palm over both of my wrists, pinning them gently against my knees.
Fingers catch my wrist the moment I reach for another spool of linen.
His thumb drags across my pulse point, absent and instinctive, as if the motion exists outside his conscious thought.
"Cassia, the elders have the water handled.
Everyone's settling in." His tone drops into that quiet register he only uses when we're sharing the same breath. "You can stop for tonight."
