Sol-86 never slept, but it dreamed. Deep inside the station’s logic, microsecond burps of history stitched themselves into the present, then rolled forward as if nothing had ever happened. Nova, walking the empty corridor, felt the dream tense before the scream.

  A single, brutal strobe that popped every shadow and sent the corridor’s spectrum into nuclear white. She winced, but that only made the audio worse: a keening whine like feedback, followed by a system-wide bone-rattle as every access panel and status monitor dumped its cache at once. The air buzzed with ions and melted insulation. Down the length of the hall, lights flickered between seizure and blackout, then settled into a slow, nauseating pulse. Nova’s eyes adapted in one blink. The others were not so lucky.

  The echo pulse hit the candidates in the next passage like a chemical weapon. Two staggered to the floor, hands clamped over their skulls, retching onto the wipe-clean polymer. Another, a first-cycle girl whose name Nova had forgotten, stood ramrod straight, eyes unblinking, a line of blood running from her left nostril. The last—tall, broad, too proud for the intake—spun and drove his own fist into the wall, then clawed at his hair with such force that a tuft came loose. Nova watched the violence register in the system’s sensors; then, like a choreographed move, every wall panel opened, dispensing a smart-foam patch to each candidate. Only the girl took it, slapping the med-patch to her neck with practiced surrender. The others ignored the aid. The corridor swelled with the high wet stink of panic.

  Emergency overlays projected onto the nearest surface:

  SYSTEM DISRUPTION. SEEK SHELTER. HOLD POSITION.

  Nova ignored both. She advanced, already calculating how far she could get before security protocols took the next step. She passed the first-cycle casualties without a glance. Further on, the corridor was deserted, the system trusting in its own lockout to keep trouble at bay.

  But the station wasn’t the only thing with memory. The pulse—its signature, its rhythm—was not random. Nova recognized it at once: the same harmonic ratios, the same uncanny lilt as the error trace she’d seen in calibration. This time, though, it wasn’t just watching her. It was everywhere.

  She pressed on, boots scraping over the static-slicked surface. The corridor kinked hard, and for a moment the strobe was behind her, outlining every detail of her silhouette in negative. At the next intersection, a support drone lay in a heap, its chassis bent at a vicious angle. Nova checked for movement; the status light was out. She stepped over the drone, ducked beneath a low-hanging fire suppression node, and reached the perimeter of the sanctioned zone.

  At the access checkpoint, the system’s reader was dead, its glass lens spiderwebbed with microfractures. Nova punched the panel anyway. Nothing. She glanced up, tracking the layout in her memory: the old maintenance artery cut right from here, abandoned after the last station overhaul. If anything was still breathing inside the wreckage, it would be in there.

  She pushed through a soft barrier—grafted polymer, not meant to be elegant—and found herself in a zone that smelled of dust and ozone. No one had cleaned here in months, maybe years. The overheads were dark, but the pulse from the main ring still lit the passage in steady waves. Her eyes flicked left and right, mapping the geometry: every door on this stretch was sealed tight. All but one.

  The terminal room. They used to call it the Graveyard—half as joke, half as threat. It was where old interfaces went to die, and where the instructors exiled problem cadets for unsupervised diagnostics. Nova keyed the door: locked, but not up to current security. She fished out her multi-probe, jammed it in the access slot, and gave the system three seconds to remember her. It failed. The lock yielded with a muted click.

  Inside, the room was a disaster. Dust blanketed every horizontal surface; the heat exchangers on the main rack ticked with the slow, arrhythmic pulse of hardware kept alive only by inertia. Against the far wall, a line of terminal stations flickered, most dead, one guttering in and out of a diagnostic menu. Nova shut the door behind her and leaned into the darkness, letting her eyes acclimate.

  She moved to the live terminal, cradled her gloved hand over the reader, and waited for the handshake. Nothing. She flexed her fingers, felt the old burn scar tingle, and this time forced the connection: “Override. User: Ardent, N. Security tier: provisional.”

  The system did not respond in words, but the screen jumped—first to a tangle of code, then to a user interface that looked like it had been scraped off a museum wall. Nova’s heart jackhammered in her chest. She bypassed the onboarding screens, drilled into the local data store, and found what she’d come for: the external memory module, hardwired into the frame and physically labeled with a serial number that matched the one from her brother’s last assignment.

  Her fingers worked the haptic surface, burning through password attempts and two-factor prompts with a practiced speed. At the third prompt, the system tripped a logic bomb, locking her out and threatening to overwrite the drive. Nova didn’t blink. She let the overwrite proceed for six seconds, just long enough to pass the first cycle, then yanked the module and reversed the power flow. The system, unable to reconcile a living process with its own execution, fell into a loop, and for a moment every screen in the room shimmered with the afterimage of a face: dark eyes, hair pulled back, expression a millimeter from panic.

  Jace.

  Nova stabbed the haptic again, this time in manual mode, and waited for the system to purge. When the screen cleared, a single file floated on the surface: NO-RETURN / CANDIDATE. She opened it.

  The footage was raw, security-cam bad, all skewed angles and off-color contrast. It showed Jace in a pressure suit, hunched over a containment console that vibrated with every frame. The background was unlit, but Nova recognized the old lattice, the first generation of what became LUMEN. Jace’s hands moved with desperation, punching override after override. He looked up once—right at the camera. There was blood in the crease of his nose, and his left eye had gone glassy. Nova paused the frame, but the image shimmered, refusing to stabilize.

  She played it again.

  Jace wasn’t dying. He was fighting. The screen behind him read:

  MEGABOT CORE—SEAL OVERRIDE / FINAL. He typed, voice shaking: “There’s a pattern. You have to listen for it. It’s not in the system log—”

  The footage jittered, then cut to a wider view. Something enormous, barely visible, loomed behind the containment glass. Light bent around it, distorting the pixels. Jace pressed his forehead to the glass, hands braced, then shouted, “It’s not malfunctioning, Nova. It’s communicating.”

  The file ended. Blackness, then a shiver of static, then nothing.

  Nova’s hand hovered over the panel, trembling. Her mouth tasted of iron and plastic. She glanced at the clock in the corner of the screen; seventeen seconds had passed since the first pulse. She catalogued the data: the message, the pattern, the breach. She closed her eyes and replayed the last line. It’s communicating.

  Behind her, the door opened. Not the soft, guilty click of a cadet, but the deliberate, military sound of someone who expected to be obeyed.

  Nova did not turn. She kept her hand on the console and waited. The silence stretched, heavy as solvent.

  Finally, a voice. “This area is off-limits to candidates. You’re not authorized.”

  Nova’s body stilled. She recognized the speaker immediately—Rhea Kaito, returned from her rumored exile, but now with an edge of authority that hadn’t existed before.

  Nova closed the file, wiped her fingerprints from the reader, then turned, slow and deliberate. Rhea stood in the doorway, not blocking it, but radiating the kind of threat that only needed to be implied. Her uniform was pristine, every seam sharp enough to cut. Her face was hard, unreadable, but the eyes—once bored, now vivid and cold—took in everything at a glance: the illegal access, the patchwork of dust on Nova’s knees, the fever-bright flush at her cheekbones.

  “You’re back,” Nova said. Her voice surprised her, steady and flat.

  Rhea’s gaze slid past her, to the terminal, to the still-warm access point. “I have new responsibilities. You’re a variable of interest.”

  Nova bit the inside of her cheek, watching for the telltale twitch at Rhea’s temple. None came. “I’m not a threat.”

  “That’s not my call.” Rhea moved closer, just inside the boundary where Nova would have to retreat to maintain space. “I am, however, expected to monitor you. Closely.”

  Nova’s hands curled into fists, the gloves creaking. She thought of Cassidy’s warning, the implication of scrutiny layered on scrutiny, and understood that she was being audited in real-time.

  Rhea’s tone softened fractionally. “Your calibration scores. The sync rate. I’ve seen anomalies before, but never like this.” She gestured at the screen. “You’re not just fast. You’re contaminated.”

  Nova’s face went blank, but inside, ice cracked open. “That’s not the term anymore. Quartus uses ‘resonant.’”

  Rhea’s lips twisted. “It’s not an upgrade.”

  A pause. The hum of the dying terminal filled the gap.

  Rhea stepped back, motioning for Nova to follow. “Report to the secure ward. I’ll walk you.”

  Nova hesitated. “You’re not going to ask what I was doing?”

  Rhea’s eyes flicked up, sharp as a blade. “You’ll tell me eventually. Or the system will.” She said it with perfect certainty, the way only someone raised on system logic could.

  They left the room together, the silence between them dense and transactional. As they stepped into the corridor, Rhea angled her head, just so: “Next time, you’ll need to be faster. I was expecting you here.” She paused, then, as if making a private joke: “You’re not the only one with family in the system.”

  Nova didn’t answer. Her mind ran the footage again and again, looking for frames she’d missed. Jace’s face, the message, the last twitch of his mouth before the screen cut out.

  It’s not malfunctioning, Nova. It’s communicating.

  Behind them, in the Graveyard, the terminal flickered back to life for an instant. On the screen, rendered in font smooth as oil, a single line:

  ANCHOR RECOGNIZED: NOVA ARDENT

  Then the room went cold, still, and very, very quiet.
