The platoon filed out of the dim theater and into the high-walled concrete corridor, their heavy training boots scraping against the grit of the poured stone.
Jack kept his left arm pinned rigidly to his side, his thumb hooked into his belt to keep the limb still.
Beneath the coarse fabric of his uniform, the cold pressure of the implant remained, a frozen weight buried deep against his radius bone like a coin of dead winter.
He kept his eyes locked on the back of Vance’s sweat-damped neck, allowing the rhythmic, heavy movement of the squad to draw him forward.
The passage was narrow, a grey chute of rib-vaulted concrete that carried the low hum of the ventilation system and the smell of sulfur-laden ash from the training fields.
It was the kind of space that amplified sound, turning every muttered word and heavy breath into a wet, sliding echo.
Jack fell into step, Kayla moving slightly to his left with a silent, watchful stride, her eyes scanning the shadows of the junction ahead.
They were only three paces from the heavy steel threshold of the armory when Ryker veered out of the march.
The movement was abrupt, a violent snapping of the squad’s momentum.
Ryker planted his heavy boots in the center of the corridor, his jaw tight, his shoulders braced.
The recruits directly behind him stumbled, their chest rigs and modular gear clattering in a chaotic metallic chain reaction.
A ripple of sharp, angry murmurs spread back through the column.
“Voss,” someone muttered from the rear.
“What the hell are you doing?”
Ryker did not turn.
His chest was heaving under his survival plate, his face slick with sweat and the dark residue of the volcanic dust.
His right hand rose, his index finger trembling as he pointed it directly at Jack’s left forearm.
“You want to know how he did it?” Ryker’s voice was too loud, a high, strained bark that struck the concrete walls and rattled down the passage.
“You want to know how a scavenger from the margins beat every academy-trained hand in this room?”
Jack stopped.
He did not look down at his arm.
He kept his gaze level, meeting Ryker’s bloodshot eyes.
They were wide, frantic, fixed on Jack’s sleeve as if he expected the grey synth-fiber to split open and reveal the rot beneath.
“Ryker,” Jack said.
His voice was low, flat, a caution he hoped didn’t sound like a plea.
“Stand down.”
“Stand down?” Ryker let out a short, cracking laugh that carried no humor, only the brittle edge of a pride that had been ground into the dust.
“You are a gutter-born thief. Your range scores are flawless. Your drill times don’t even match your enlistment file. You climbed a sheer basalt chimney in full gear with no harness, a vertical chute that should have broken your neck.” He took a sharp step forward, his boots clicking on the masonry.
“And during that footage, when the screen showed the marking, you froze. Your arm seized. I saw your face go white as bone.”
Vance stepped into the gap, his broad shoulder coming up like an iron shutter between Jack and the pointing finger.
“Back off, Voss. You lost the trial. Crawl back to your bunk and nurse your ego there.”
“You think this is about the trial?” Ryker’s voice cracked, his finger darting around Vance’s shoulder to jab toward Jack.
“He has an implant. A black-market neural interface. I know the signs. I studied the clinical cases at the preparatory academy. The localized spasms, the sudden cold flashes, the way he constantly favors that left arm like it’s made of glass. His body glitched the second that Vorthak came on-screen.”
Kayla moved with silent precision, planting herself beside Vance.
Her boots were flat on the concrete, her hands loose but ready at her sides.
Her voice was a quiet, freezing warning.
“You are making a dangerous mistake, Ryker.”
Ryker ignored her, his breath coming in ragged, shallow gasps.
His focus remained locked on Jack’s sleeve.
“You felt it, didn’t you? Whatever illegal wire you have in there, it reacted to the footage. You went pale.”
Jack remained silent, his hands sliding slowly into his pockets.
He could feel the fine, rapid tremor beginning in his left fingers, and he needed them hidden from the dozen pairs of eyes now turning toward him.
The word scavenger hung in the air, carrying the old, familiar sting of the margins, a reminder of the dirt he had tried to scrub from his skin.
The surrounding recruits had gone entirely still.
Nobody spoke.
Nobody moved.
The silence of the corridor was heavy, expectant.
Then the crowd parted.
Drill Sergeant Kovac shoved through the stalled line of recruits, his heavy, iron-shod boots striking the floor with a slow, deliberate cadence.
He grabbed Ryker by the shoulder strap of his chest plate and jerked him back a pace, his grip tight, his scarred face inches from the recruit’s eyes.
“What is this disruption?” Kovac’s voice was a low, dangerous rasp, barely louder than a whisper, yet it silenced the entire corridor.
Ryker pulled himself into a rigid attention, his chin lifting, though his chest still heaved.
“I am making a formal accusation, Drill Sergeant. Recruit Calloway is carrying unauthorized subdermal equipment. Black-market neural hardware. I have observed the physical markers.”
Kovac’s eyes, cold and bisected by old training scars, slid slowly to Jack.
Jack kept his hands in his pockets, his left wrist tucked deep against his thigh.
He met Kovac’s gaze and held it, refusing to blink.
He saw no surprise in the sergeant’s face, only a calculating, procedural coldness.
Kovac had watched the impossible chimney climb too.
He had been waiting for a reason to look closer.
“Did you hear the accusation?”
“Yes, Drill Sergeant.”
“And?”
Jack said nothing.
Kovac’s jaw tightened.
He looked at Ryker, then back to Jack, then at the silent, watching faces of the platoon.
The moment stretched, the tension in the narrow corridor thickening until it felt as heavy as the volcanic air outside.
Kovac turned his head toward the dark mouth of the corridor junction and flicked his wrist.
“MPs.”
Two armored military police stepped forward from the shadows of the transit archway.
They were not CDF regulars.
They wore the heavy, matte-black helmets and red brassards of the security detail, their hands resting near the grips of their sidearms and folding shock batons.
They flanked Jack before he could draw another breath.
“Wait,” Vance said, his hand twitching as if to grab Jack’s shoulder.
“You can’t just…”
The lead MP shifted his weight, his black-plated chest blocking Vance’s path, a warning hand rising to settle on his baton.
Kayla stepped forward, her pale face tight with a quiet fury, but she was forced back by the second guard.
“Shut up, Reyes-Thorn,” Kovac said, his tone flat and unyielding.
“Get back in line. All of you, remain in the corridor.”
The MPs gripped Jack by the elbows, their gloved hands hard and unyielding as iron clamps.
They steered him out of the formation and down a sterile, metal-paneled corridor that smelled of ozone and industrial wash.
Jack did not resist.
He kept his head level, his arms limp, his eyes focused on the floor panels ahead, refusing to look back at the pale, helpless anger on Vance and Kayla’s faces.
The lead MP pushed open a heavy steel door with a dull copper hydraulic seal.
The small, white-lettered sign on the metal read: Diagnostic Interrogation Room 4.
Inside, the room was small and windowless, built like a salvage-deck operating theater.
The walls were bare metal panels, stained with the dull, yellowish residue of chemical washes.
A single high-intensity light bar ran across the ceiling, casting a flat, clinical white glare down upon the steel-backed diagnostic chair bolted to the center of the floor.
The MPs guided Jack to the chair, one of them forcing him down until the cold metal bit through his uniform and pressed against his spine.
The other slammed heavy magnetic restraint cuffs over his wrists, pinning his left forearm, and the hidden parasite living beneath his skin, flat against the diagnostic plate.
The magnetic cuffs activated with a low, vibrating click.
Jack tried to pull his wrists against the restraints, but they did not give a millimeter.
The flesh above the implant was pressed hard against the sensor array, leaving no space, no margin for error.
Breathe, he told himself.
Keep still.
Investigator Hale entered the room.
He was a thin, clinical man with eyes like glass beads, his grey CDF uniform immaculate.
He carried a mobile neural scanner console, setting it on a metal cart beside the chair with slow, deliberate movements, like a surgeon arranging instruments.
He did not look at Jack.
Kovac and a rigid, tightly coiled Ryker followed, standing near the door frame.
Ryker’s face was pale, his eyes fixed on the display with a desperate, hungry focus.
“Subject is secured,” Hale said, his voice entirely devoid of warmth.
Kovac nodded.
“Run the diagnostic.”
Hale reached up and pulled a semi-circular sensor arch down from the ceiling track.
The arch descended with a smooth hydraulic hiss, positioning itself over Jack’s skull.
The small glass nodes stopped millimeters from his temples.
Jack stared straight ahead, focusing his eyes on a tiny, circular rivet on the opposite metal wall.
Beneath his skin, he could feel the implant beginning to pulse.
It was a tiny, rhythmic beat, like a trapped insect trying to find an exit.
Stay quiet, he thought, aiming the plea deep into his own flesh.
Stay down.
Hide.
The machine did not answer.
Hale tapped the console screen.
A high-frequency electromagnetic hum filled the room, so high it made Jack’s molars ache.
The sensor arch glowed with a pale violet light, and Jack felt the muscles in his jaw clamp shut as a sharp static spike flared behind his eyes.
His skull felt as if it were being squeezed in a vise, but he forced his features to remain completely blank.
He could not see the terminal screen directly, but in the polished reflection of the glass node hovering near his left temple, he saw a jagged, ugly white line jump violently upward on the display.
“Calibration noise,” he muttered, tapping the screen to reset the threshold.
The jagged line held for a fraction of a second.
Then, Jack felt the implant shift.
It was not a physical movement, but a sudden, agonizing alteration of the pressure within his bones.
A freezing, needle-like current surged up his wrist, through his elbow, and into the base of his skull.
His fingers clawed helplessly at the iron frame of the armrests as the thing under his skin adapted, altering its presence to blend seamlessly into his own nervous system, wrapping its foreign signals in the messy, irregular patterns of human biology.
In the reflection of the glass node, the jagged white spike flattened, smoothing out into an ordinary, lazy loop of human alpha and beta waves.
Jack remembered Intake.
He remembered Medical Officer Dunne’s lazy dismissal of a faint glitch as mere “equipment noise.” But Dunne had been processing hundreds of raw recruits; Hale was searching for a traitor.
Hale frowned, his brow furrowing as he stared at the readout.
“Secondary sweep running.”
The room hummed again, the pitch rising to a dog-whistle whine.
Jack felt the scanner’s current dip down the length of his left arm, tracing every centimeter of the implant’s hidden boundary.
His skin prickled with an intense, numbing cold.
His heart hammered against his ribs like a trapped bird.
The terminal chimed, a clean, electronic double-beep.
Hale leaned away from the console, his shoulders dropping as he reviewed the finalized data.
He tapped the interface, saving the clean scan directly to Jack’s permanent conscription medical file.
On the secondary display, Jack’s recruit serial number flashed beside the green, block-lettered status: CLEAR.
“The subject’s neural architecture is entirely clean,” Hale reported, his voice flat.
“No cybernetic modifications. No black-market hardware. Standard muscle density, minor thermal drift. The initial fluctuation was standard equipment noise.”
Kovac stepped forward, his heavy fingers tapping the control panel on the armrest.
The magnetic cuffs released with a loud, metallic clack.
Jack pulled his arms free slowly, his fingers completely numb, his left forearm aching with a deep, dull throb.
Kovac turned his bulk toward Ryker.
He took a single, massive step, backing the recruit up against the steel door frame.
His face was inches from Ryker’s, his voice dropping into a low, gravelly promise of violence.
“You wasted high-priority training assets,” Kovac said.
“You brought a public accusation against a squadmate with nothing to back it but your own bruised ego. You cost this unit time we do not have.”
Ryker’s mouth opened, then closed.
The color had completely drained from his face, leaving the soot on his cheeks looking like bruises.
“I should have you routed to corpse recovery or a forward probe unit today,” Kovac continued, his eyes drilling into the recruit.
“But I am going to let you stay. You are going to pull auxiliary kitchen duty until your fingers bleed. You will scrub the transit bays with a hand-brush, and you will sleep when I allow it. And if you ever waste my time with your jealousy again, Voss, I will personally sign the transfer that puts you on a forward reconnaissance line with no extraction profile. Do you understand me?”
Ryker stood rigid, his jaw clenched so hard his teeth audibly ground together.
He did not look broken; his pride had turned into something cold, hard, and silent.
“Yes, Drill Sergeant.”
“Get him out of my sight,” Kovac barked.
The MP grabbed Ryker by the shoulder strap and steered him out of the room.
Ryker did not look back, his shoulders stiff, walking with the forced stride of a man refusing to show he had been beaten.
Jack pushed himself up from the diagnostic chair.
His legs were unsteady, his left arm hanging like a dead branch at his side, entirely devoid of feeling.
Kovac watched him, his scarred face unreadable.
“Barracks, Calloway. You are off the armory rotation for the next two hours. Go lie down before you pass out on my floor.”
“Yes, Drill Sergeant.”
“The magnetic scan often causes mild cognitive drift and physical disorientation,” Hale added, not looking up from his logs.
“Walk it off.”
An MP guided Jack out of the interrogation room, leading him back to the main corridor before turning him loose.
Jack walked alone.
The corridors of the Bastion were quiet, the overhead strip lights flickering with a dull, yellowed hum that seemed to vibrate directly inside his skull.
He kept his left hand tucked into his pocket, his skin freezing, a cold sweat breaking out across his forehead and collarbone.
When he reached the barracks, the room was empty and silent, the other recruits still held in the training rotation.
He collapsed onto his thin mattress, his fingers clutching the cold iron frame of the bunk.
The room began to spin.
His head was burning.
The biological cost of the implant’s defense was rising through his system like acid through a conduit.
His blood felt thick, hot, and heavy.
He clutched his skull in the silence, understanding with a sickening clarity that the machine had saved his life by consuming his own physical reserves.
He closed his eyes, but the darkness brought no relief.
The blue-white static behind his eyelids grew brighter, more intense, beginning to web outward into thin, star-like lines of light that traced the interior of his mind.
The cold of the iron frame beneath him faded, replaced by an all-consuming, dry heat that made his breath rattle in his throat.
He lay in the quiet, unable to tell if his eyes were open or closed, his mind slowly drowning in a silent, branching storm of alien light.
