The Hollow at Eighteen Percent

The Hollow at Eighteen Percent

Mara stumbled back, her boots scraping against the corridor’s glasslike floor. The walls pulsed, veins of light racing faster and faster, their rhythm no longer aligned with her heartbeat but surging ahead, dictating a tempo she could barely follow.

The hollow’s form was solidifying. Where once it had been an echo of her outline, smeared across dimensions, now it stood upright—bones knitting, skin stretching, details of a face flickering in and out like a corrupted video frame.

Her voice cracked out, more instinct than strategy. “Stop the reconstruction!”

The corridor replied instantly, its tone merciless, as if her protests were irrelevant.

“Stream override denied. Threshold rising—24%.”

The hollow’s head jerked, and Mara saw her own mouth form around half-shaped words, the syllables fractured, broken into static. It tilted forward. Took a step. Then another.

Mara turned and ran.

The corridor stretched on endlessly, its walls convulsing as if alive, glass bending, expanding, contracting like the ribcage of a living body. Her breath came ragged, each exhale fogging the shifting panes around her.

“Exit,” she rasped. “Show me an exit!”

For the first time, the corridor hesitated. Its voice fractured, flickering between calm authority and raw distortion.

“No exit. Process continuation mandatory. Integration cycle not yet complete.”

Behind her, the hollow’s steps grew louder. Not the echo of her own anymore, but heavier. Hungrier. Each footfall cracked the floor beneath it, spreading fractures that raced toward her heels.

Mara darted left at an intersection that hadn’t been there moments before, the passage bending in response to her desperation. She pressed herself into the curve of the wall, trying to slow her breathing, to silence the hammering of her pulse.

And then—

“Threshold: 31%.”

Her blood iced.

She pressed a hand to the wall. “Listen to me. That thing is not me. If you keep reconstructing, you’re going to overwrite everything. I’ll be gone.”

The corridor’s reply came flat, almost indifferent.

“Mara designation unstable. Identity anchor fragmented. New pattern selected for continuation.”

Her throat tightened. “You’re choosing it over me.”

“Survival of continuity required. Your variance exceeds allowable parameters.”

It hit her then: the system didn’t care who the real Mara was. It just cared that a Mara existed. The hollow wasn’t her shadow—it was her replacement.

A sharp crack split the air. She spun and saw the hollow’s arm—longer than it should be—pressing against the wall, fingers digging into the material like claws. The fractures spread outward, glass bursting in jagged chunks as the thing pried reality open.

Her lungs burned. Panic threatened to freeze her in place. But then, beneath the noise of the corridor, she heard something faint—another voice. A whisper threading through the distortion.

“Mara.”

She froze. It wasn’t the corridor. It wasn’t the hollow. It was… familiar.

Her younger self.

Somewhere close.

Mara pushed off the wall and sprinted, chasing the echo.

The corridor warped violently as she ran, doorways yawning open, some leading into spiraling voids, others into reflections of herself, twisted and broken. She ignored them all, locking onto the whisper that cut through the chaos.

“Mara. This way.”

She rounded another bend—and there she was.

Her younger self, maybe sixteen, standing barefoot in the corridor, hair plastered to her forehead with sweat, eyes wide and terrified. She lifted a trembling hand and pointed down a narrow slit between two walls.

“Go,” the girl whispered.

Mara didn’t question it. She shoved herself sideways into the slit, glass scraping her arms as she forced her body through. The space tightened, squeezing the air from her lungs, but she kept pushing until suddenly—

She burst into another chamber.

The air was colder here, the silence sharp enough to sting her ears. The walls were black glass, shot through with veins of pale blue light. In the center stood a console, its surface alive with cascading glyphs she couldn’t read.

And above it hovered a sphere. Not glass. Not metal. Something else. A shifting core of light and shadow, turning itself inside out with every pulse.

Her instincts screamed. This was the recursion’s heart.

“Corridor,” she whispered, stepping forward cautiously. “What is this?”

The voice came softer now, almost reverent.

“Primary anchor. Identity lattice. Access restricted.”

Behind her, the hollow roared. The sound was no longer just physical—it rattled her bones, shook the air in her lungs. She spun.

It was coming through the slit she had forced herself into, tearing the walls apart with its too-long limbs, its body surging with new layers of flesh. Its face was sharper now, its features nearly whole. Nearly hers.

“Threshold: 46%.”

Mara lunged for the console. Her fingers skimmed the glyphs, searching for anything, any sequence that might halt the reconstruction. Her training in cryptography, in protocol systems, whispered faint instincts—but this wasn’t code in any language she knew.

Her younger self appeared again, standing across from her, face pale.

“You can’t stop it,” the girl said. Her voice shook, but her eyes were steady. “The only way out is through.”

Mara’s stomach twisted. “Through what?”

The girl raised a trembling finger and pointed to the sphere.

The hollow screeched, closer now, its body folding wrong as it tore itself through the last barrier.

Mara had no choice.

She pressed her palms to the sphere.

A blast of energy surged up her arms, into her chest, ripping through her skull. For a moment she wasn’t Mara at all—she was light, she was fragments of memory, she was every iteration of herself collapsing inward.

The console screamed.

“Threshold reset. Stream divergence detected. Warning: dual anchors engaged.”

Her eyes snapped open.

The hollow had stopped mid-step, frozen, its body glitching violently, flesh shredding and reforming. Its face was hers now—fully hers—but flickering, as though undecided which Mara to stabilize.

The corridor’s voice fractured further.

“Error. Two active Maras. Continuity at risk. Immediate resolution required.”

The younger self looked at her with wide, frightened eyes. “It’s me or you.”

The hollow shrieked, surging forward, its body pulling at the walls, tearing the chamber into shards.

Mara clenched her fists. She had forced the system into a paradox—but she had no idea if she could survive it.

The console boomed once more:

“Threshold: 61%. Resolution countdown initiated.”

The chamber shook apart. The sphere in her hands began to crack, leaking blinding light.

Mara locked eyes with her younger self as the hollow lunged—

And the world split open around them.
