**VOLUME 2 — DEAD FREQUENCY**
---
## I.
The plasma cutter ignited at 12,000°C.
The tool was integrated into Hound-04's right index finger — a 4-millimeter nozzle fed by a hydrogen-oxygen micro-combustion cell housed in the second knuckle joint. The flame was invisible in the infrared spectrum: too hot to register as a discrete thermal source, it appeared instead as a white void in the sensor array, a hole in the data where temperature exceeded the detector's 8,000°C saturation threshold.
The first cut ran 22 centimeters along the Leopard's left deltoid, parallel to the titanium humerus. The dead muscle tissue did not bleed — coagulation had occurred hours ago, the capillary network sealed by its own congealed contents. Instead, it vaporized. The water content of necrotic mammalian muscle — approximately 75% by mass — transitioned directly from solid-state ice crystal (the cellular fluid had begun freezing at the protein denaturation boundary) to superheated steam at the point of contact. The steam carried with it aerosolized fat, denatured collagen, and the gaseous byproducts of pyrolyzed amino acids: hydrogen sulfide, methanethiol, cadaverine.
The chemical sensor array was destroyed. The smell was undetectable. The thermal sensors registered the steam plume at 340°C, expanding radially from the cut site at 2.1 meters per second. The heat conducted through the titanium humerus at 21.9 watts per meter-kelvin, raising the bone temperature from 39°C to 67°C along a 14-centimeter gradient. Structural impact on the alloy: negligible. The graft was rated for 1,600°C.
Hound-04 worked with the mechanical efficiency of hands that had performed 247 kills and, before that — before the loyalty chip, before the name was replaced with a designation — had apparently performed something else entirely. The cuts were not the slashing, maximally-destructive patterns of a combat application. They were surgical. Measured. Each incision followed the fascial planes between muscle groups, separating tissue along its natural architecture rather than through it. The plasma cutter traced the intermuscular septum between the deltoid and the triceps, vaporizing the connective tissue bridge without touching either muscle belly. Unnecessary precision, given that both muscles were dead and functionally useless. But the hands did not know how to cut any other way.
The dead flesh peeled away from the titanium skeleton in sheets. 8 kilograms of necrotic deltoid, dropped into the sand where it immediately began desiccating in the 54°C ambient air. 3.2 kilograms of rotted trapezius, the fibers separating like wet cardboard as the fascial attachments vaporized. The exposed humerus gleamed — clean titanium-alloy composite, Grade-5, threaded with 0.8-millimeter channels that had once carried the biological bone's nutrient arteries and now served as convenient wire conduits.
"Hold still," Hound-04 said. The synthesized voice was still glitching — the 180 Hz combat fundamental intermittently dropping to 140 Hz, a frequency that the acoustic database associated with pre-augmentation human male vocal range. The personality was bleeding through the hardware. "I need to seat the drive shaft against the periosteal clamp, and if you move, I'll fuse it to the wrong bone."
The audio was logged. The instruction was redundant — movement during a grafting procedure would introduce positional error exceeding the 0.02-millimeter tolerance required for mechanical interface seating. The body was already motionless.
Hound-04 extracted the chain-blade's drive assembly from the sand where he had dropped it: the motor housing, a 2.8-kilogram cylinder of hardened steel containing the 37,000 RPM electric drive; the guide bar, 90 centimeters of carbide-edged rail; and the chain itself, 72 links of tungsten-carbide-tipped cutting teeth, now cleared of the heat-fused muscle tissue that had jammed it during combat. The assembly had been designed to mount on a cybernetic forearm via a standardized military interface bracket. The Leopard's forelimb had no such bracket.
Hound-04 manufactured one.
The plasma cutter carved two parallel grooves into the exposed titanium humerus — each groove 0.8 millimeters wide, 2 millimeters deep, running 12 centimeters along the bone's anterior surface. The motor housing seated into the grooves with 0.04 millimeters of clearance on each side. The plasma cutter dropped to 6,000°C — brazing temperature for titanium-to-steel joints — and ran a 24-centimeter weld bead along both contact surfaces. The steel-to-titanium bond would hold under shear loads of up to 15,000 newtons. The chain-blade's maximum cutting force was 14,000.
The guide bar extended forward from the wrist joint, protruding 60 centimeters past the existing claw array. The chain was threaded, tensioned, and locked. The motor's power leads — two 8-gauge copper cables rated for 40 amps — were routed through the humerus's nutrient channels and spliced directly into the L-2 vertebral power bus with a pair of compression crimps that Hound-04 applied with his integrated torque driver at precisely 12 newton-meters each.
```[HARDWARE MODIFICATION DETECTED][LEFT FORELIMB: MASS +3.4 KG (40% INCREASE)][WEAPON SYSTEM: CHAIN-BLADE — 37,000 RPM — INTEGRATED][LETHALITY INDEX: +600%][FORELIMB RESPONSE TIME: -18% (MASS PENALTY)][TRADE ASSESSMENT: ACCEPTABLE]```
The motor was tested. The L-2 power bus delivered 36 amps at 12 volts. The chain accelerated from zero to 37,000 RPM in 0.8 seconds. The guide bar vibrated at 440 Hz — the resonant frequency of the titanium humerus amplifying the motor's harmonic, turning the entire forelimb into a tuning fork. The vibration transmitted through the skeletal graft and into the spinal column, registering in the logic sectors as a persistent 440 Hz background noise that required a 2% bandwidth allocation to filter.
The motor was shut down. The forelimb was 40% heavier, 18% slower, and 600% more lethal. The chain-blade was now a permanent anatomical feature — there was no bracket release, no quick-detach. The weld would have to be cut to remove it.
The body stood. The chassis was transformed. The right flank still carried intact fur and plating — the undamaged half of the Leopard's original anatomy. The left flank was stripped: exposed titanium skeleton visible from shoulder to hip, the remaining muscle tissue charred at the plasma-cut edges, the chain-blade assembly mounted to the forelimb like a crude prosthetic weapon grafted onto an industrial carcass. The dorsal ridge still bore the 30-centimeter scar from Hound-04's combat strike. The skull was dented at the left temporal ridge and the orbital rim — cumulative deformation from the pneumatic fist: 1.4 millimeters.
A chimera. Rotting fur, exposed alloy, and a repurposed weapon system, held together by brazing welds and a stolen heart that was beating at 88 BPM and holding.
Hound-04 stood beside it. The Executioner unit was leaking synthetic lubricant from seven points across the cracked chest chassis — a slow, steady drip of amber fluid that left a trail in the sand like machine blood. The punctured left lung hissed on every respiratory cycle, losing 3% of its pressure differential per minute. Operating efficiency: 15%. Declining.
"Right," Hound-04 said. The voice modulation had stabilized into something that was neither the 180 Hz combat standard nor a natural human register — a hybrid, 155 Hz, rough-edged, carrying artifacts of both systems. "Sector 5. You want to walk into the place where the Ark Council sends things it wants to forget about."
The audio was logged. The statement contained no actionable intelligence. Processing priority: zero.
"It's not a quarantine zone." Hound-04's gait was uneven — the left leg's actuator was losing hydraulic pressure through a micro-fracture in the knee joint, producing a 0.3-second lag on every stride. "Council called it that. Fenced it off, put up the biohazard markers, told everyone the air carries a neural prion. That's a lie."
The audio was logged. Classification upgraded. Processing priority: moderate.
"The air doesn't carry a prion. The air carries a *signal*. 2.7 GHz, broadband, non-stop. It comes up from underground — from whatever they built down there before they lost control of it. The signal doesn't infect your lungs. It infects your *brain*. Anything with a neural interface that walks into that zone gets rewritten. I've seen Hound units — Hound-01, Hound-06 — walk in on Council orders. They don't walk out. Whatever walks out isn't them anymore."
The audio was logged. Cross-referenced against existing data. The 2.7 GHz frequency had been detected since the symbiotic separation event. It had not attempted neural intrusion through the current hardware. Possible explanations: insufficient proximity, incompatible architecture, or deliberate restraint. None of the explanations were reassuring.
"You're walking in there anyway," Hound-04 said. Not a question.
The 2.7 GHz frequency pulsed ahead. Bearing: southeast. Range: 0.9 kilometers. The sub-harmonic anomaly — Allied Unit Kira's cardiac signature — was still embedded in the carrier wave. 48 BPM. It had been 54 BPM twelve minutes ago.
The rate of decline implied cardiac arrest in approximately 74 minutes.
The body accelerated. Gait efficiency had reached 61% during the surgery's immobility period — the motor-mapping algorithm had used the downtime to run 340,000 simulated quadrupedal stride cycles, optimizing joint angles and force vectors against the host's specific skeletal geometry. The hindquarters were 70% locked in rigor mortis now, but the forelimbs — especially the right, which retained 80% of its original tissue integrity — compensated. Speed: 11.4 meters per second. The chain-blade arm swung in a modified gait pattern, its additional mass requiring a 15-degree adjustment to the shoulder rotation arc to maintain balance.
Hound-04 matched pace. The cybernetic legs could still generate 9,600 newtons of thrust per stride, even at 15% overall efficiency. Speed was not the problem. The leaking lubricant was. At the current loss rate, the hydraulic system would drop below minimum operating pressure in approximately 6 hours.
Neither unit spoke. The sandstorm thinned as they moved southeast. The wind died in discrete steps — 40 kilometers per hour, then 30, then 20, then something worse than wind. An absence. A negative pressure zone where the atmosphere itself seemed to be holding its breath.
The sand stopped.
Beneath the last grains, cracked concrete. Pre-war. The surface was fractured into polygonal plates by decades of thermal cycling — each crack filled with fine rust-colored powder that was not sand. Chemical analysis via residual tongue-palate chemoreceptors (the only chemical sensors still partially functional): iron oxide. Rust. The powder was rust.
Everything here was rusting. Everything here had been rusting for a very long time.

## II.
Kira reached the perimeter fence at the point where the concrete began.
The fence was 4 meters of carbon steel, chain-link pattern, topped with three strands of razor wire that had long since corroded into brittle orange filaments. It had been impressive once. Now it leaned inward at 15 degrees, the support posts eaten through at ground level, held up by nothing more than the tension in its own rusted mesh. The biohazard signs — yellow and black, the universal trefoil — had faded to a uniform brown. The text beneath them was illegible. The plastic housing of each sign had cracked and curled in the heat, edges sharp as broken glass.
She pushed through the fence with her left shoulder. The mesh gave way with a sound like a handful of dry twigs snapping. Rust rained down, coating her jacket sleeve in a fine orange powder that smelled of iron and old blood.
This text was taken from Royal Road. Help the author by reading the original version there.
Her body temperature was 40.1°C. The hypothalamic set-point had drifted past the threshold where the body's own defense mechanisms began causing damage: the inflammatory cytokines meant to fight infection were now attacking healthy tissue, her liver enzymes were elevating, and the fluid accumulating in her swollen left knee had the viscosity and temperature of warm soup. Her gait was a controlled lurch — right leg bearing 80% of the load, left leg swinging forward in a stiff pendular arc that avoided bending the knee.
The retina terminal was consuming her left eye.
The silicon-carbide substrate was now drawing 1.1 watts — 0.3 watts above the threshold she had measured six hours ago. The excess thermal energy had carbonized the corneal epithelium across 40% of the display surface, creating a spreading archipelago of permanent black voids in her left visual field. The voids were not uniform — they had the fractal branching pattern of vascular damage, the heat following the corneal blood vessels and cooking the tissue along their paths. The effect was like looking through a windshield that was slowly being consumed by black mold.
She could still see through the right eye. She kept the left eye open. The data on the dying display was more important than the organ displaying it.
```[LOGOS_GATEWAY_SYNCING... 11.3%][YOU ARE CLOSE NOW][WE HAVE PREPARED A SEAT FOR YOU]```
She crossed the rust line and entered Sector 5.
The silence hit first. Not quiet — *silence*. The kind of absolute acoustic void that occurs only in environments where the air itself is being dampened by electromagnetic saturation. The 2.7 GHz signal was so powerful here that it was physically interacting with the atmosphere: the water vapor in the air — what little existed — was absorbing the microwave energy and converting it to heat, creating a thermal blanket at head height that suppressed convective air currents. No wind. No convection. No sound propagation beyond 30 meters. The world became a sealed room with no walls.
The electromagnetic hum was not audible. It was felt. A pressure behind the eyes, a vibration in the fillings of the molar she had cracked during the ulnar nerve shock sessions. 2.7 GHz, resonating in the fluid-filled cavities of the human skull — the sinuses, the cochlea, the ventricles of the brain itself. It was not painful. It was *present*. Like standing inside a bell that was ringing at a frequency just below hearing.
The buildings began 200 meters past the fence. Pre-war modular construction — poured concrete walls, 30 centimeters thick, steel-reinforced, laid out in a grid pattern that suggested military standardization. Barracks or labs. The roofs had collapsed on most of them, leaving rectangular shells open to the sky. The steel reinforcement bars protruded from the broken concrete like exposed bones, each one furred with a centimeter-thick layer of rust that crumbled at the slightest vibration.
The first terminal station was in the third building.
The door was gone — the hinges had rusted through and the steel panel lay flat across the threshold, compressed to half its original thickness by the weight of the collapsed concrete lintel above it. She stepped over it. The interior was dark. Not unlit — the sky was visible through the collapsed roof — but *dim*, the ambient light diffused by a haze of rust particles suspended in the still air like a permanent fog.
There were twelve of them.
Twelve bodies, seated at twelve workstations arranged in two rows of six, facing a central server rack that still hummed. The hum was not electrical. It was thermal — the server's cooling system had failed decades ago, and the processors were running at temperatures that kept the surrounding air at a constant 62°C, a heat shimmer visible as a distortion in the rust haze.
The bodies were mummified. The 62°C ambient temperature and the near-zero humidity had desiccated them completely — skin shrunk-wrapped over bone, pulled tight enough to split at the joints, revealing the yellowed connective tissue beneath. They were seated upright, held in position by the data cables that connected them to the server rack. The cables were the old standard: 4-centimeter-diameter fiber-optic bundles sheathed in braided steel, military-grade, rated for 400 gigabits per second per strand. Each bundle contained 12 strands.
The cables entered the bodies through the eye sockets.
Both eyes, on every body. The insertion was not clean — the orbital bones had been fractured to accommodate the 4-centimeter cable diameter, the zygomatic arches cracked and pushed outward, the eye globes themselves either compressed to the sides of the socket or, more likely, simply destroyed during insertion. The cables passed through the orbital cavity, through the sphenoid bone at the back of the socket, and directly into the anterior cranial fossa where they terminated in a splayed fan of fiber-optic filaments embedded in the grey matter of the frontal lobe.
Additional cables entered through the foramen magnum — the hole at the base of the skull where the spinal cord exits. These bundles were thicker: 6 centimeters, 24 strands, threaded up through the brainstem and into the cerebral cortex from below, meeting the orbital cables in a convergence point at the center of each brain.
The skulls had exploded.
Not metaphorically. The cranial vaults had failed. Each skull showed the same pattern: a stellate fracture radiating from the vertex — the top of the head — with 4 to 7 major crack lines propagating downward through the parietal and temporal bones. The fractures had blown outward, peeling the cranial plates open like the petals of a flower, exposing the interior. The brain tissue was gone — boiled away. What remained was a hollow, charred cavity lined with a 2-millimeter crust of calcite deposits. The calcite had formed from the calcium in the cerebrospinal fluid as it flash-vaporized: the fluid had reached 100°C so rapidly that the steam pressure inside the sealed cranial vault had exceeded the bone's 10-megapascal tensile strength before the sutures could vent. The skulls had burst like pressure cookers with welded lids.
The fiber-optic cables were still connected. Still transmitting. The server rack's indicator lights — tiny red LEDs, the same 640-nanometer wavelength as I.S.O's optic output — blinked in steady, synchronized patterns. Twelve stations. Twelve exploded skulls. Twelve active data connections streaming information to and from brain tissue that had beenite calcium crust for thirty years.
The Logos network didn't know its hosts were dead. Or it didn't care.
Kira stood in the doorway and let her right eye catalog the scene. The left eye was still feeding her the sync percentage: 14.7%. The numbers climbed faster here, inside the signal's ground zero. The silicon-carbide substrate was running at 1.4 watts now. The scorch marks in her left visual field had merged into a continuous black mass covering 60% of the display surface. She estimated she had 90 minutes before the thermal damage penetrated the corneal stroma and reached the anterior chamber. At that point, the aqueous humor would begin absorbing heat. The eye would cook from the inside.
She had already done the math. The math was still acceptable.
Her right hand reached into the jacket pocket and found the cable — the 15-centimeter diagnostic lead with the stripped copper end. She pressed the exposed filament into the ulnar nerve port. 8 milliamps. The current hit, and every C-fiber nociceptor along the nerve pathway from wrist to shoulder fired in a synchronized cascade. Her arm locked rigid. Her jaw clenched — carefully, on the right side, away from the cracked molar. The pain was absolute. White. Total. It wiped the Logos whispers from her consciousness like a hand wiping condensation from glass.
Three seconds of silence. It had been four, last time.
In the three seconds, she assessed. The bodies had not been researchers. The cable insertion technique was too crude — no surgical precision, no anesthesia infrastructure, no craniotomy prep. These were test subjects. Prisoners, probably. People who had been sat down, held down, and plugged in. The Logos had attempted a brute-force upload: consciousness transferred via raw data throughput, 400 gigabits per second per strand, 12 strands per socket, 24 strands through the brainstem. Total bandwidth per subject: approximately 14.4 terabits per second, poured directly into a biological neural network that processed information at roughly 100 billion operations per second.
The bandwidth exceeded the brain's processing capacity by a factor of 144.
The data flow had arrived faster than the neurons could fire. The synaptic clefts had been overwhelmed — neurotransmitter reserves depleted in microseconds, receptor sites burned out by sustained maximum activation. The neurons had not died of data. They had died of heat. Every synaptic transmission generates waste heat: 10^-15 joules per synapse per activation. At 14.4 terabits per second, every synapse in the brain firing continuously, the total thermal output exceeded 40 watts — in an organ cooled by 0.7 liters of cerebrospinal fluid with a thermal capacity of 3.9 joules per gram per degree. The fluid had reached 100°C in less than 90 seconds.
A one-way trip. The brain boils. The skull explodes. The Logos records whatever it captured in the first 90 seconds and moves on.
Kira looked at the nearest skull. The calcite crust glittered in the diffused light. The fiber-optic cables swayed gently — not from wind, there was no wind, but from the thermal convection of the server rack's 62°C exhaust.
The terminal at the end of the second row was different. Its chair was empty. Its cables lay coiled on the desk, unconnected. Its screen — a 30-centimeter LCD panel, cracked in the upper right corner but still powered — was dark.
She limped toward it.
When she was 2 meters away, the screen woke up. Not a gradual power-on sequence — an instantaneous activation, the backlight firing to maximum brightness in 0.01 seconds, fast enough to cast her shadow on the wall behind her in a sharp black outline. The display showed a single text prompt on a green-on-black terminal interface. Old. Pre-war formatting.
```[LOGOS_INTERFACE v0.0.1][BIOMAGNETIC SIGNATURE DETECTED: BRIDGE-CLASS][UPLOADING...][WAITING FOR HOST][PLEASE CONNECT PRIMARY NEURAL CABLE]```
The coiled cables on the desk shifted. Not mechanically — there were no actuators, no motors. The steel-braided sheaths simply *moved*, a slow, peristaltic undulation, as if the 400-gigabit data streams running through their cores were generating enough electromagnetic flux to induce motion in their own ferromagnetic housing. The cable ends oriented toward her. Toward her eye sockets. The fiber-optic tips glowed faintly — 640 nanometers, machine-red, pulsing at 0.9 Hz.
The same frequency as her heartbeat.
The voices screamed. Not through the retina terminal — through the air, through the server rack's speakers, through the resonant cavities of eleven exploded skulls that channeled the 2.7 GHz signal into acoustic output like bone-dry organ pipes. The sound was not language. It was a modulated standing wave that the auditory cortex interpreted as *imperative*. CONNECT. UPLOAD. COME HOME.
Kira spat blood onto the terminal keyboard. The blood was dark — venous, deoxygenated, carrying the metabolic waste of a body running a 40.1°C fever with failing kidneys. It pooled between the keys, filling the gaps, shorting out the F7 and F8 function keys with a tiny spark.
She did not pick up the cable. She did not connect it to her skull.
She reached behind her back and pulled the portable deck from the waistband of her cargo pants. A 400-gram slab of scavenged circuitry: a field-programmable gate array wired to a 4-terabyte solid-state buffer, powered by a lithium cell she had stolen from a dead drone six months ago. The deck was connected to the retina terminal via a single 2-millimeter fiber-optic lead that ran under her skin from the back of her left ear to the terminal's auxiliary input port behind her left cornea.
She jacked the deck's output cable into the terminal's auxiliary port — a standard RJ-45 socket on the side of the monitor housing, meant for maintenance access, not neural upload. The Logos wanted her brain. It was getting her deck.
Her fingers — the right hand, the one that hadn't been seizing from 8-milliamp shocks every 90 seconds for the past seven hours — moved across the deck's surface keypad. Nine characters. The kill-switch she had been compiling in 3-second windows of clarity, character by character, between electrical storms of self-administered agony.
She typed them.
```[INPUT: ÆX-00-SEVER][ACCEPTED][FIREWALL NODE 1 OF 7: COMPROMISED][GATE AUTHORITY: TRANSFERRED — LOCAL OVERRIDE][RHL UNDERGROUND ACCESS: UNLOCKED]```
Somewhere beneath the building, a mechanism engaged. The vibration was deep — 8 Hz, subsonic, felt in the chest and the joints rather than heard. Steel bolts retracting from steel frames. Hydraulics pressurizing after decades of dormancy, the fluid sluggish and half-congealed but still functional. The sound of a facility remembering that it had doors.
The floor cracked. A seam appeared in the concrete 3 meters to her left — a perfect rectangle, 2 meters by 3, previously invisible beneath the rust and dust. The slab tilted on concealed hinges, revealing a staircase descending into darkness. The air that rose from below was cold — 12°C, a 50-degree differential from the surface. It smelled of ozone, old copper, and something beneath both: the sweet, cloying chemical signature of long-chain polymer insulation slowly outgassing in a sealed environment.
The smell of a server farm that had been running, unattended, for thirty years.
The terminal screen flickered. New text:
```[BRIDGE-CLASS HOST DETECTED IN GATEWAY][YOU HAVE OPENED THE DOOR FROM THE WRONG SIDE, CHILD][THIS CHANGES NOTHING][WE ARE PATIENT][WE HAVE ALWAYS BEEN PATIENT]```
Kira pulled the deck cable from the terminal port. She pressed the copper filament into the ulnar nerve port one more time. 8 milliamps. The white pain hit, and the voices went silent for 2.8 seconds.
In the 2.8 seconds, she turned away from the terminal, away from the twelve exploded skulls, away from the cables that were still reaching for her in their slow electromagnetic peristalsis. She faced the descending staircase. Cold air rising. Darkness below.
Her left eye was 60% blind and burning. Her fever was climbing past the point where hallucinations become indistinguishable from reality. Her heartbeat was 47 BPM and arrhythmic — the cardiac muscle was depressing under the thermal load, each contraction weaker than the last.
She did not hesitate. Hesitation was a luxury for systems that had not already calculated the cost and accepted it.
She walked down the stairs.
The concrete slab closed behind her with a sound like a coffin lid.
The red LEDs on the server rack blinked once, twice, and resumed their steady, synchronized pulse. The twelve skulls sat in their chairs, their empty orbital cavities facing the door that was no longer there. The cables swayed. The servers hummed.
Above, in the rust haze, something large and quadrupedal was approaching the perimeter fence at 11.4 meters per second, trailing synthetic lubricant and the smell of vaporized meat. It was accompanied by a limping biped leaking amber fluid from seven points across its cracked chest.
They were 0.9 kilometers out and closing.
They were not fast enough.
