She emerges, blinking, into the final stretch of the Looking Glass tower.

  The first thing she notices is the noise: a deep, vibrating hum from the logic stacks. The vibration travels upward from her boots to her teeth. Next is the cold—more like a void replacing heat, leaving only emptiness where warmth should be. The air crackles with static so thick it feels dangerous, as if even the empty spaces inside the tower could pose a threat.

  The spiral staircase no longer exists. In its place is a partially melted helical ramp, twisted like soft metal. Each step is a block of code that visibly switches between a solid and error state; at times, it flickers, briefly vanishing before returning. A new step forms just as the previous one tries to trap her, threatening to drop her into nothingness. There are no handrails—only an endless void below, and the memory of failed attempts by other versions of Alice, each trapped in a recursive loop, endlessly repeating their falls.

  She climbs. The ramp shivers, each step precarious, daring her to slip. Still, she pushes on.

  Her HUD stutters into view, then dies again. When it is up, it is only to shout warnings:

  SYSTEM CORRUPTION:

  94%. SANITY: ±7%.

  MEMORY: READ-ONLY.

  She ignores it, but the numbers stick, like splinters in her peripheral vision.

  After three steps, the tower’s defense activates. Pure code slices the ramp. Alice dives and rolls free as a beam burns past. Pain floods her thigh—her Threadmancer circuit pings, sharp and metallic.

  She tries to stand, but the platform is gone. Gravity inverts and tosses her; she lands face-first on the next ramp, barely catching herself.

  “Shit,” she hisses, breath fogging in the cold. “Almost funny.”

  She recovers, movements automatic. She’s run tower defenses before—just never one that mattered this much.

  The ramp steepens. Ahead, razor data beams cross and shift, each on a different cycle. She counts beats, then sprints.

  Beams burn her suit, slice her bicep. Her left arm goes limp, but she pushes on.

  She lands on a sliver of platform, which cracks and fractures into darkness. Dropping to one knee, she gasps and looks down.

  Below: every failed level she’s survived. Above: more ramp, more beams, more malicious logic.

  The walls are made of mirror-like code—not truly solid, but polished to a sheen that reflects everything. Each surface shows countless twisted reflections of Alice at slightly different moments, moving almost but not quite in sync with her. She tries not to look, but with these reflections surrounding her, avoidance is impossible.

  The Threadmancer module in her skull wakes up with a sick jolt. The blue-white lines under her skin glow, pulses matching her heart—even though the body is digital, the sensation is real. She channels just enough power to the step beneath her to stabilize it, making the shifting glass turn temporarily solid beneath heBut using the power comes at a cost: her vision splits in two. For a moment, she sees herself as two separate images—one calmly climbing, the other in the reflection screaming, wrists bleeding, mouth full of glass. The screaming version clearly shows her worst fear—that she will fail. The two versions pull against each other to be real, then merge again into one, but the unsettling feeling remains. Lingers.

  She climbs.

  This time, the defense system skips subtlety and goes straight for the kill. The ramp ahead splits apart, creating a gap six meters wide, impossible to jump, impossible to bypass. On the other side, the platform shivers, daring her to try.

  She checks the drop, but the darkness is infinite. No bottom, no backup plan.

  “Of course,” she mutters. “Because fuck you, that’s why.”

  She weighs her options. Threadmancer lines throb—each use shreds reality. Sanity: 3%. She laughs. Why not?

  She backs up, gets a running start, and hurls herself across the gap. At the apex, she throws everything she has into the Threadmancer overlay, willing the air itself to become solid, just for a moment.

  It works. A code-bridge appears—three steps, then collapses. She crashes onto the far platform, teeth rattling, but grabs the edge in time.

  She pulls herself up, dragging her ruined avatar over the edge, collapsing with her face on cold glass.

  The HUD disappears, replaced by a progress bar that glows blue. Above it, "FINALIZE" signals the system's final stage.

  She groans, rolls onto her back, and stares up into the heart of the tower.

  The ceiling is gone. Only a vertical shaft remains, full of spikes and razor beams, flexing constantly to throw her off.

  She gets to her feet, legs shaking, left arm barely functional. The cut on her bicep is leaking code, each drop hissing as it hits the floor.

  She climbs, using spikes as handholds. Beams slice her thighs, back, and neck, but she keeps moving, fueled by momentum and refusal.

  Halfway up, a gravity well activates, pulling her to the side into the mirror wall. She tries to brace herself, but the force is overwhelming. She slams into the glass, the impact sending a shockwave up her spine.

  She looks up and sees herself in the reflection. This Alice is not climbing. This Alice is falling, mouth open in a perfect, silent scream.

  She wrenches free, grabbing a spike. The wall burns her palm with raw data, pain blurring her vision.

  She clings to the spike, breaths coming in short, ragged bursts.

  The Threadmancer overlay is in full revolt now, painting the world in stuttering frames: one moment she is halfway up, the next at the base, the next standing on the rim looking down at herself from above. The recursive loop is tight, vicious, designed to break her will. She tries to focus, tries to find the right now, the real now.

  She closes her eyes, just for a second. When she opens them, the world has stabilized, and she is at the top of the shaft, one last lip between her and the end.

  She pulls herself up, rolls onto a tiny platform just big enough for her to collapse again. The glass here is hot, almost soft. It ripples under her weight, as if wanting to swallow her whole.

  She is shaking, every muscle and line of code in her body at war with itself.

  She gets to her knees, then her feet, then staggers forward, the floor dissolving behind at the ramp’s end, a door waits for her. Instead of a normal door, it’s a thin, shimmering sheet of light and code, stretched tight and vibrating with a faint sound just above her hearing. It feels like a barrier between one world and another.

  She touches it with her burned hand. The pain is almost a The membrane moves like water, then parts. Behind it lies a world of glowing gold—a light so intense she can see nothing else. This isn’t just light; it’s the result of every struggle and victory she’s endured, all collected into one shining space.

  She steps through.
