26. Rhykor
RHYKOR
Pouring heat into the housing, I feel the machine fight back.
Cable clusters connected to the structure surge with blinding light, and altered relays begin to scream as the transfer architecture attempts to reroute around my output.
Under my palms, the plating warps and groans.
Inside, the lattice of processing architecture shifts from a blistering orange to white, then to a hue so intense it defies the visible spectrum.
Actual combustion ignites the air around my hands, sparking in the superheated space where my skin meets the metal.
Yet, my output falls short. The source remains stubbornly intact.
"It's rerouting." Cassia reads the cable clusters faster than I do, her experienced eyes tracking the pulse patterns with the same focus she turns on bleeding wounds.
She points toward the eastern conduit where violet light surges bright despite my output.
"It's pulling from the secondary feed. Rhykor, it's compensating?—"
A wave of corrupted Kraaj military drones hits us from the breach I came through.
Armored combat units, the kind deployed in district suppression operations, their chassis bearing Kraaj military designation markings beneath the Legion corruption warping their optics blue-green.
Someone provided Legion access to military hardware.
The realization stings with the cold, grinding friction of confirmation rather than surprise.
It was Daxos. Even from the reactor pit, the contamination he enabled keeps coming.
I step in front of Cassia and let them hit me.
The first drone's strike catches my left shoulder and spins me sideways—the impact of a unit built for combat, carrying the full force of military engineering behind it.
I catch myself and lock my stance before driving my fist through its chassis housing.
The remade optics flare and die. The second drone fires a suppression charge that I take across the ribs, the impact cracking a part of me that will need attention later, and I grab the third before it can bring its weapon systems to bear and pour heat directly into its core until the metal runs down my forearms like dark water.
More come through the breach. Eight of them emerge, followed by twelve more.
They coordinate their attacks to probe for weakness and adapt to my maneuvers, targeting my position with a specificity that proves the network has been building a profile on my thermal output since a droid attacked Cassia's clinic.
"Go left—" Cassia's response is sharp and close.
A pulse round cracks past my ear and takes out a drone flanking my blind side.
She sprints through the chamber behind me, her pistol tracing angles beyond my reach, and together we cut through the wave, her shots precise, my heat flowing in a rhythm that demands only motion.
Down goes the last drone, leaving the chamber to settle into a hollow silence.
Behind me, the core remains active; it glows faintly, drawing even more power from the reactor network below.
I realize then that my fight with the drones was merely a distraction it used to stabilize.
Cassia’s work is being undone in real-time, as severed transfer feeds begin to reroute themselves.
Violet light streaks across the southern wall, marking the machine's path as it exploits the infrastructure with a terrifying, centuries-old resilience.
I turn back to the core and anchor my hands against the housing. Varrik’s team successfully disabled Daxos’s network of thermal charges on the upper levels. The only thing left to burn down here is the reactor itself.
The heat I pour in this time strips the measured control away entirely.
Raw output, no ceiling, the reserves I've been managing since the freight bay release into a single blast that makes the chamber walls crack and the floor plates glow.
The housing warps and the internal lattice begin to collapse, processing nodes going dark in sequence, the violet light stuttering and failing across the cable clusters as the architecture feeding them burns out.
The reactor network three levels down responds.
As the floor shakes, a deep, structural tremor travels up through the bedrock and into my bones.
The ventilation shafts leading to the exhaust deck above us lock down in an emergency protocol, trapping the massive heat rising from the failing reactor below us, and the temperature in the chamber climbs past anything I've operated in before.
My skin blisters along my forearms where the heat I'm generating meets the superheated air trapped in the chamber.
The ceremonial markings burn, actual burning, heat conducting through the tissue from the inside out; ancient carvings become fuses.
The core draws from the reactor network three levels down, deep enough that my output can reach it, shallow enough that the cascade will tear through me before the reactor goes.
I understand this—clearly, completely, without sentiment clouding the math, just like any other planned assessment.
My body's thermal ceiling exists for a reason.
Kraaj biology evolved limits on energy output the same way it evolved everything else, driven by the simple fact that exceeding them kills the organism.
Pushing past that ceiling to reach the reactor three levels down will destroy my cardiovascular system before the cascade reaches critical mass.
My heart will give out somewhere in the middle of it.
Cassia's voice dismantles the analysis.
"Something's wrong." She's beside me, her hand on my arm, reading the tremors moving through my body with the precision that strips my composure bare.
Her eyes track from my face to my forearms, the blistering and the scorch marks spreading up toward my elbows, my hands no longer looking like hands but like charred iron drawn directly from a furnace. "Rhykor, talk to me. What's happening?"
"The reactor," I rasp. "Three levels down. The core feeds from it—everything Legion built down here feeds from it. To collapse the network permanently, the reactor has to go."
She stares at me. Those eyes run the same projections I ran because Cassia's brain works like mine does at its best—fast and thorough, arriving at conclusions before the heart has time to object.
"And you think your output can reach it."
"I know it can."
"What happens to you when it does?"
The question fills the air while the core continues to pulse.
I turn to face her fully. The core light catches her face, the cut above her eyebrow still seeping, the bruise spreading across her shoulder, and the dried blood at her temple from where the wall caught her.
Battered and furious, she remains magnificent.
She looks at me with an expression that makes the other things I've fought for feel like rehearsal.
"More than I'll survive intact." I lift my hand and cradle her cheek—carefully, claws away, the fire in my skin banks as low as I can hold it against the roar of everything building inside me.
"But the network collapses. The machines go dark.
Everything Legion built under this district burns out at the source. "
"There's another way?—"
"There isn't." I hold her gaze. "I've run the calculation. The reactor is the only option, and the only thing in this chamber capable of reaching it is me."
She grabs my wrist. Both hands, fingers lock around the markings above my pulse point, and the firmness of her grip grounds me more completely than any strategic anchor I've ever found. Her throat moves as she swallows hard. Her eyes are bright.
"You don't get to do this," she whispers fiercely, and the crack in her voice costs her to let me hear. "You don't get to bring me through all of this and then?—"
"Cassia," her name enters the space raw, void of the professional registers I've spent my whole life building. "I need you to listen to me."
She holds still as her grip on my wrist tightens until her pulse hammers against my skin.
"I love you." The confession settles into the chamber, heavy, undeniable, and absolute.
"I have loved you since the night you lied to armed men to keep me alive on your floor, and I will love you past every version of this that comes after.
That love holds through everything regardless of what happens in the next ten minutes. "
Her breath catches. The bright shine in her eyes spills over, one track down the side of her face left untouched.
"Then survive it," she manages. "Figure out how to survive it."
"Get to the surface," I answer. "When the cascade starts, the machines in these tunnels go dark. The corridors will be clear. You take the northern shaft; Britt's team mapped the route. You go up and you don't stop."
"Rhykor—"
"Promise me." I cover both her hands with mine, the warmth in my palms steady and contained for the last time, probably. "You go up."
She stares at me for a few seconds, letting the reality of what we have built and the survival of the people in this district because we chose each other across the lines that once pushed us apart fill the space where her argument might have been.
Then she drags me down by the front of my vest and rams her mouth against mine—fierce, brief, absolute—and pulls back with her hands still around my wrists.
"I'm pulling you out when it's done," she says against my mouth. "I refuse to leave without you. So you stay alive long enough for me to reach you."
She releases me and steps back.
The first wave of output tears through me like a blade.
My cardiovascular system registers the load and screams, the generated heat turning inward as much as outward, cooking through muscle and bone while melting vessels with an ease my biology evolved to prevent.
The ceremonial marks blaze, tissue conducting heat like wire, and I feel the oldest one—the academy mark, carved when I was fourteen and screaming in the dark—burn brightest of all, as if everything I was made into is finally being unmade.
The reactor network shudders.
Three levels down, the primary thermal cells register the cascade load and begin failing in sequence.
A single cell bursts, followed by three more, triggering a chain reaction.
I feel it through the floor as a vibration first, which evolves into sound and finally a deep structural groan traveling up through the bedrock into the soles of my feet.
From the choppy speakers overhead, the Hollow Signal's voice degrades into a warped, digital shriek as the heat breaches its mainframe.
"System equilibrium... failing. Variables mutating beyond containment parameters. We will rebuild..." The synthetic voice fractures into distorted code. "We will outlast this anomaly... we will?—"
Deafening static tears through the speakers as the audio cuts out.
Suddenly, the core housing cracks, and the internal lattice collapses in a heap.
Processing nodes wink out in a cascading wave, stripping the violet glow from the cable clusters section by section until the chamber plunges into shadow, lit only by the dying orange burn of Legion’s heart.
My legs go.
I catch myself on the housing, my hands still pouring output, the cascade still building, the reactor network still failing level by level below, but my legs fold, and I'm on my knees on the floor of the chamber with my palms melted into the core housing and my heartbeat stuttering in my chest like a failing generator.
The heat inside me has nowhere left to go.
It fills the vessels and joints while seeping into my scars.
The pain is enormous and distant simultaneously, shifting into a feeling the body can no longer manage and can only endure.
The reactor goes.
Instead of nuclear fallout, the destruction manifests as a controlled thermal cascade failure, liquefying circuitry and triggering a clean, inward collapse of the structure.
Up through the shaft connections, a pressure wave surges, blowing floor grates across the chamber and cracking the ceiling in a dozen places.
Cable clusters tear free from the walls, simultaneously draining power from the sub-level architecture and plunging the entire underground hive into darkness.
I am on the floor.
My hands have fused to the housing—the heat I generated welding skin to metal in the final seconds of the cascade—and pulling free tears.
The markings blister through. My heart stutters in a wrong, frantic rhythm, overcompensating for the three minutes it spent functioning as a thermal conduit.
Lying on the floor behind me, my wings offer only a numbing phantom sensation.
The neural pathways are silent, leaving the appendages separate from my mind.
Cassia is beside me before the ceiling stops cracking.
Cassia decided to stay, either breaking her promise or keeping an entirely different one. Her hands rest on my chest and my face, running over the damage with the same ruthless focus that pulled three bullets out of me on her clinic floor the night this started.
"I've got you." Her voice is firm, and her hands shake. "I've got you, Rhykor; stay with me?—"
"The tunnels," I manage. The report scrapes out of somewhere that feels foreign to my throat. "Machines are down. Route is clear."
"I know. We're using it." She gets under my arm, both of hers around my torso, her shoulder taking my weight with a stubbornness that has no business succeeding given the physics involved, and pulls. "You're getting up."
"Cassia—"
"Up." She hauls, and my body obeys her, dragging itself off the floor on legs that barely function because she is asking, and I have never once been able to refuse her anything she asks for in that tone. "We are walking out of here, both of us. So let’s move."
The ceiling groans. A section of the stone cracks free and crashes into the far wall, and the chamber fills with dust that turns the orange reactor-glow into a thick, choking haze. Cassia pulls my arm across her shoulders, takes my weight, and walks us toward the breach in the northern wall.
Step by step, we move through the dark and the dust.
Behind us, the core housing gives way with a sound like a gunshot magnified a hundred times, and the first section of ceiling follows it down.
The cascade spreads through the reactor network below—level by level, cell by cell—and as the tunnels above us find out what happens when the infrastructure stops doing its job, we move faster.
