24. Rhykor
RHYKOR
The first tunnel collapses twenty minutes in.
We're moving through the old drainage network beneath Sector Twelve, our twenty-person alpha team representing half the strike force assembled from all corners of the district.
Humans and Kraaj are shoulder to shoulder in corridors built for maintenance drones and forgotten machinery, pushing forward until the ceiling ahead gives way.
The sound is enormous, a grinding cascade that swallows two scouts in a wall of debris before anyone can react.
Dessik pulls the others back while I cover the retreat, pouring heat into the charging wave of transformed machines that surge through the fissure.
They pour from the openings, a coordinated swarm that moves with a visceral wrongness, exhibiting a speed and precision that overrides any survival instinct, leaving only the cold drive of their orders.
Legion knows we're here and has known since we dropped through the surface hatch.
"Eastern branch!" Varrik bellows from behind me, his cane cracking against the floor plates as he braces. "Britt, take your team through the eastern branch before it closes—move!"
Britt goes, and half the force peels right, their boots pounding toward the access point that leads north toward Cassia's last reported position.
I plant myself at the junction and hold it, pouring thermal blasts into the advancing machines while the split happens around me, burning a line between the units and the retreating people until the heat distortion makes the corridor shimmer like a mirage.
The machines adapt. They always adapt. A wave of smaller units, remade cargo drones whittled down to their chassis and welded into mechanical insects, floods the ceiling, and two crew members take hits before we identify the new approach vector.
I burn them out of the overhead conduit with a blast that leaves my forearms shaking and the air tasting like melting circuitry.
We push through anyway.
The deeper we go, the more the infrastructure reveals what it's become.
Legion has been rebuilding down here for months—longer than any estimate we'd built—and the evidence lines every wall.
The evidence lines every wall with relay nodes embedded in ancient stone like teeth growing through bone.
Cable runs pulse with infected light, threading through corridor junctions in patterns I recognize as network architecture rather than random infestation.
Furthermore, machines are assembled from parts that have no business existing together—military components grafted onto civilian chassis and industrial tools repurposed as weapons by an architect that knows exactly what it's building.
They target me specifically.
I notice it by the third skirmish. The units in each engagement lock onto my position before the pulse rifles crack to my left or Dessik's crew ignites their plasma torches, moving faster than the armed scavengers making noise.
The swarms orient on me first by probing my thermal output like they're measuring it before committing their heaviest units to suppress my position while smaller units work around the edges toward the others in the force.
"It's profiling you," Varrik calls during a brief lull, his eyes tracking the pattern. "The attack rotations center on your energy signature. Whatever is running this network has a very specific interest in you."
"I know." I scan the corridor ahead, seeing numerous cable nests alongside pulsing nodes as violet luminescence turns the stone walls the color of a bruise.
The mate bond provides a quiet resonance, Cassia's heartbeat layered with mine, pulling me deeper with a gravity that makes the machines converging on my flanks feel like an inconvenience. "Keep moving."
We lose two more crew in the next sector, a structural collapse and then a combat drone that got inside our formation before anyone identified it as military-grade rather than the standard industrial units we'd been fighting.
Even though I destroy it, the damage is done, and the faces carry names I know—a scavenger from the eastern quarter who donated half her salvage reserves to the shelter supply runs and a Kraaj mechanic from the compound who repaired the clinic generator twice, entirely unbidden.
Bearing their names, I keep moving.
The upper thermal exhaust deck announces itself with heat.
Heat rising through the floor plates belongs to machinery older and more industrial.
Rolling waves venting from the reactor levels deep below that make the air above the grating shimmer and dance.
The chamber opens ahead, the corridor widening into a vaulted space where the original military infrastructure has been left structurally intact.
Thermal exhaust pits run the length of the chamber floor, deep channels venting the district's emergency power reserves that have long since been co-opted by whatever is rebuilding itself below.
Orange light climbs from the pits in curtains, and the superheated steam venting from the grates smells of burning metal and a biological char I refuse to identify.
Catwalk systems cross the space above the pits in overlapping grids. Old, riveted ironwork built for inspection personnel who no longer exist stretches across the ceiling; compromised walkways droop toward the heat below where the support welds have failed over decades.
We spread into the chamber in formation, weapons up. The attack we're braced for never arrives.
Instead, I hear measured boots. Someone is walking out to meet us.
Daxos comes from the northern catwalk with six combat-ready soldiers flanking him and another dozen at entry points around the chamber's upper level.
His ceremonial armor catches the orange glow.
He wears black composite plating with campaign insignia across the surfaces, his cybernetic wing clicking with each adjustment.
He walks to the edge of the high catwalk and looks down at us like a man surveying property he wants to demolish.
Those tarnished-brass eyes sweep our unified strike force of scavengers and market workers standing alongside the Kraaj who serve under my command, standing alongside humans who grew up calling his species an occupying force, and his mouth pulls into an expression between disgust and satisfaction.
"There it is," Daxos says. The theatrical projection from the Kor-Viir briefing chamber is gone, reduced to a private, ugly reality.
"The Dragon's army. I had intelligence reports, but seeing it in person.
" He pauses, letting the contempt do the work.
"Half a century of Kraaj military superiority, and this is what you choose to defend it with. "
"Stand down." I keep my tone level. "You're standing in the middle of a Legion hive. Your political agenda stops mattering about twenty levels up."
"My political agenda is the only reason there's still a Kraaj presence on this planet.
" He descends two steps on the catwalk, moving into better position above the reactor pits—a terrain advantage I note and file.
"You've misunderstood the nature of this situation, Rhykor.
You always misunderstood it. That's always been your failure. "
The chamber holds its quiet as steam vents hiss and the grinding shuffle of machine movement echoes somewhere deeper in the tunnels. My crew fans out behind me, instinctive, reading the angles.
"Command identified the AI fragment six years ago and spent eighteen months evaluating its utility," Daxos continues, his tone toneless with the unyielding confidence that comes from having rehearsed this delivery.
"The containment failures, the escalating attack patterns—all managed.
We fed the machines our access codes, and in exchange, they recognize my command cipher as friendly. The outbreaks were an asset."
"An asset you're about to incinerate," I grind out, finally understanding how he walked through miles of aggressive, infected infrastructure without a scratch. "You rigged this entire network to detonate remotely. Why come down here to gloat?"
Daxos’s mouth straightens into a thin, irritated line.
"A seamless plan until Legion’s localized interference jammed the remote detonator frequencies.
"A minor inconvenience, though deploying a transport to this wretched district personally because my signals were blocked is deeply tedious," he sneers.
"I came down to initiate the manual override sequence myself and retrieve the primary intelligence core before this entire sector turns to molten glass. "
The disclosure enters the chamber and sits there.
Behind me, I hear the changing breaths of humans who survived multiple outbreaks and lost people to coordinated droid attacks before fleeing burning corridors while children screamed.
I also hear the Kraaj, who served under my command, running supply drops to families sickened by Legion-infected tech.
It had been eighteen months. It was a cynical investment in suffering, made by men in clean armor who have never been in the sectors they condemned.
"You fed it military supply chains."
"We provided infrastructure access. The quarantine protocols, the containment failures, the escalating attack patterns—all managed.
The purge authorization is the final chapter.
Clean the district, install compliant leadership, resume operations.
" He looks at me with those indifferent, predatory eyes.
"You were supposed to implement this. That was your assignment. That was your purpose."
"I have a different purpose now."
His mouth compresses. "Yes, my intelligence division has been thorough.
The mate bond with a human woman. The Dragon, brought to heel by a biological error our ancestors should have excised from the bloodline generations ago.
" He descends another step, wings spreading slightly—preparing. "She has made you weak."
