The next morning, Nova returned to Quartus Tower, her mind still bruised and humming from the previous night’s digital raid. The seventy-seventh floor had changed: where once there was the sullen drone of after-hours maintenance, now every surface vibrated with a daylight clarity that seemed engineered for maximum exposure. The new LUMEN training suite occupied the entire east wing—a vault of brushed metal, smoked glass, and carpet so blue it made her teeth ache.

  The sim chamber’s entrance was guarded by a retina scanner and a thumbprint plate, both freshly installed and both perfectly unnecessary for anyone with Nova’s admin hack. Still, she played along, pressing her palm flat and letting the system slurp her credentials. It chirped approval, and the wall unzipped to admit her.

  Inside, the air stung with ozone. Banks of neural interface pods lined the far wall, each cradle humming to itself, the glass skeletons lit from beneath by a pulse of blue and white. In the center of the room, a control island floated—a crescent-shaped desk with a half-dozen holo-displays orbiting it like obedient moons. Every display cycled through code patterns and user readouts, but at the heart was Cassidy, haloed in LED, hands steepled above the desk.

  “Good of you to join us, Ardent,” Cassidy said, eyes flicking up from the projection. She wore her standard-issue black, but the collar was open, revealing the microfracture scar that ran the length of her throat—a reminder, maybe, that even legends could bleed.

  Nova stepped in, letting the membrane of the chamber close behind her. “Wouldn’t miss it for the world,” she said, and tried to keep the tremor out of her voice. The neural gloves from the night before sat on a sterile tray beside the nearest pod, already polished and waiting. Nova recognized her own modifications—the thumb pad had a hairline crack, the haptic array on the right pinky was three revs ahead of the Quartus standard. She slipped them on, savoring the way the lining kissed the micro-lattice scars at her temples.

  Cassidy gestured to the pod. “We’re running advanced today. Your cycle will push past last week’s plateau.”

  Nova grinned, cracking her knuckles through the mesh. “You ever worry I’ll break your precious system?”

  A flicker of humor crossed Cassidy’s face. “If it breaks, it’s your job to put it back together.” She nodded to the pod. “Strap in.”

  Nova climbed in, letting the gel contour to her body. The helmet descended, clamping gently but firmly, and the helmet’s interior filled with cool, filtered air that smelled faintly of citrus and static. She felt the first tickle of the interface as the needles brushed her scalp, then the full handshake as the pod synced to her. The LUMEN environment booted, and the world dissolved into the familiar blue-white expanse.

  The difference was immediate. Instead of the usual grid of empty rooms, Nova was dropped straight into a running scenario: a rolling landscape of fractured ice, each surface etched with recursive patterns that threatened to collapse if she lingered too long. Above her, clouds flickered with bursts of gold and electric blue—feedback, she guessed, from other users running parallel tests.

  Cassidy’s voice spoke directly into the sim, her tone uninflected. “Your objective is to navigate the terrain and neutralize the rogue AIs seeded throughout. Difficulty will ramp every five minutes. You will not be warned.”

  Nova flexed her hands, feeling the gloves vibrate with intent. “Copy,” she said, and took off at a run.

  The terrain was hostile—plateaus that rose and fell without warning, canyons that blinked in and out of existence, swarms of digital debris that battered her avatar if she moved too slowly. Nova ignored the obvious path, choosing instead to leap sideways through a curtain of glass, trusting the system to catch her before she lost coherence. It did, barely, and she landed on a ledge overlooking a spiraling column of code.

  The first rogue AI appeared as a serpent, fractal scales each inscribed with lines of Quartus command language. It hissed, lunging at her with a mouth full of logic traps. Nova let it close the distance, then grabbed its head in both hands, forcing her resonance signature through the gloves. The code shimmered pink and gold—Ms. Titillation’s old trick—and the serpent spasmed, then dropped, limp. She dissected it with three precise movements, extracting its kernel and digesting the memory.

  Stolen novel; please report.

  The gloves grew warmer as the test progressed. Each new AI was less like an adversary and more like an organism, adaptive and hungry, trying to rewrite Nova’s strategy as fast as she could shift it. Cassidy monitored from her desk, pumping the difficulty every cycle. Nova felt the escalation as a rising tightness in her chest, a pressure that pulsed behind her eyes.

  “Heart rate’s peaking,” Cassidy commented, her voice never losing its calm. “Breath, Ardent.”

  Nova exhaled, letting her attention narrow to the sensation of data streaming through her fingers. She stopped trying to *see* the code and started feeling it: the rhythm of the system, the microbeats of processing that told her where the next threat would emerge. It was like listening to music with her entire body, and when the next AI appeared—a cloud of glass wasps, each with a mind of its own—she met them not with force, but with an invitation.

  She let the wasps land, let them probe her avatar’s surface. They stung, but instead of counterattacking, she traced their paths, mapping the logic of their movement, until a single line emerged—a flaw, a gap in their programming where the code wanted to reach for something more. Nova flexed her hand, and the gloves sparked, a rose-gold shimmer arcing up her arm. The wasps froze, then clustered together, forming a new shape: a compass, pointing her toward the next objective.

  Cassidy’s readout flickered. “You’re bleeding legacy code into the scenario.”

  Nova smiled. “If it works, it’s not a bug.”

  The next level hit like a physical blow: the landscape inverted, sky and ground swapping places, and Nova found herself falling upward through layers of impossible architecture. Every surface was a trap, every corridor a test of her nerves. She moved on instinct, ignoring pain, ignoring the burn in her muscles. At the final gate, she faced a mirror—a perfect replica of herself, armed with every exploit and trick she’d ever used.

  The gloves grew hot, the friction real. Nova circled her double, waiting for it to make the first move. It didn’t. Instead, it smiled and, in the same voice as Ms. Titillation, whispered, “You always were the clever one.”

  Nova felt the pulse of the code, the old resonance flaring bright. She reached out, touched her double’s hand, and let the merge happen. The interface flooded with sensation—loss, fear, hunger, longing—every emotion Nova had ever buried under logic now surfaced and weaponized. She let the pain pass through her, and when it was done, the mirror collapsed into light.

  The LUMEN sim froze, then reset. Nova’s heart pounded, her hands shaking with the aftershock. The helmet lifted, and she sucked in the real air, which tasted flat and too warm.

  Cassidy waited, arms folded. “You hit the ceiling in half the projected time.”

  Nova peeled off the gloves, staring at the fine sweat on her palms. “Maybe your ceiling’s too low.”

  Cassidy’s mouth twitched, the barest suggestion of pride. “Or maybe you’re ready for the real test.” She tapped a command, and the holo-displays behind her shifted, showing a map of Nova’s neural activity. The blue-white lines danced, but at the center, a single thread of gold pulsed bright.

  Nova watched the display, her smile slow and dangerous. “So what’s next?”

  Cassidy looked at her, the old challenge in her eyes. “You tell me.”

  Behind the glass, the security overlays updated—extra logins, new biometric checks, a beefed-up firewall on Nova’s home terminal. Nova saw it all, saw Cassidy’s hand in the changes, and understood: every victory was now a liability. Quartus would watch her closely. So would Cassidy.

  But that just meant the game was getting interesting.

  Nova left the sim chamber, her hands still tingling from the gloves, her mind already mapping out the next move.

  Above, the blue-white lights flickered in sync with her pulse.

  Somewhere, Ms. Titillation’s ghost purred with anticipation.
