Pool Of Blades

Water hit the tiles in sharp, clean bursts as Mandy shoved her way through the service door that wasn’t meant to open from the inside. The air in the maintenance corridor was colder than the public deck, metallic with disinfectant and something older underneath - hot circuitry, scorched plastic, the faint tang of coin-operated machines that had learned to hate bodies. Behind her, the Pool Of Blades kept singing to itself: a low thrum through the walls, like the building was breathing through a throat of gears.

A chime rang once, then again, higher. Timing. Always timing. She could feel it in her teeth.

Mandy pressed her palm to the panel beside the door. The surface was warm from use, but the screen flickered with symbols that didn’t care about warmth. A countdown bar crawled across the glass in pale green, broken by brief flashes of an emblem - an arc of steel around the number FORTY-FIVE - before the system snapped back to its indifferent interface. The bar wasn’t for her. It was for the people out there, the ones who still believed they were choosing a swim.

“Maintenance access denied,” a voice said from a speaker somewhere in the ceiling. Smooth. Female. Practiced. “Age-45 compliance window active.”

Mandy didn’t answer. She didn’t have time to argue with a building that had killed her friends on schedule. She had one goal, tight and immediate: get to the control lattice before the next group finished stepping into the pool, and find the lever that told the blades when to drop.

She yanked harder at the panel. The interface resisted, then softened - just enough. The screen changed from compliance language to diagnostic readouts, spitting out strings of numbers too fast for a human eye to follow. For a second the corridor lights dimmed, as if the system had leaned toward her.

Then the door behind her hissed and sealed.

Mandy’s shoulders tightened. Someone had locked her in - either the Pool Of Blades itself, or a watcher with a badge and a conscience that had already died at forty-five.

The corridor filled with footsteps, measured and unhurried, the kind that didn’t fear being heard. A pair of officers rounded the corner wearing pale uniforms with dark bands at the collar. Their boots made no echo. The floor swallowed sound like it was paid to.

“Citizen Mandy,” the first officer called, and the words landed with the weight of a law that had been written into bone. “You should be in Registry. You’re not scheduled for this deck.”

“I’m scheduled for oxygen and time,” Mandy snapped. Her voice came out rougher than she expected, scraped raw by cold air and the memory of water swallowing lungs. She leaned closer to the panel, trying to coax it back into a mode she could read. “Let me out.”

The second officer - taller, jaw set - didn’t move toward the panel. He moved toward Mandy, like she was the only moving part in a room designed to keep people still. “You already know the Covenant rules.”

Mandy swallowed. The corridor smelled sharper now, as if the system detected tension and compensated with chemicals. “I know the lie they call rules.”

The first officer’s gaze flicked to her hand on the panel. “The lie is that you can interfere. The Covenant is older than your anger.”

Older than her anger. Older than her life. Mandy tasted bile and copper. She forced herself to breathe through her nose, to feel the cold settle in her chest instead of panic.

A new sound threaded through the walls: the pool’s entrance mechanism, a mechanical clatter that always came right before the ritual. People being ushered, metal rails aligning, the first wave of water preparing to receive a body like it was a product.

“Why are you here?” Mandy demanded. “You think I’m some kind of criminal? I’m forty-five.” She hated how the number still sounded like a sentence. “I’ve got hours on the clock. Let me do what I came to do.”

The taller officer’s expression tightened at the mention of hours, like he’d been trained to avoid specifics. “The Covenant doesn’t care about hours. It cares about compliance.”

Mandy’s eyes burned. “That’s not law. That’s murder with paperwork.”

The first officer reached behind his belt. Not a weapon - something worse. A reader wand, its tip glowing faintly as it searched for unauthorized signatures in the air. “Step away from the panel, Mandy.”

Mandy didn’t. She twisted her wrist and pressed her fingers into the panel’s edge, where the glass met the metal frame. The interface’s green bars flickered again, and a new prompt appeared for a blink before it tried to disappear: an access code field, empty and waiting.

It wasn’t built for her. It was built for someone who knew a sequence.

Mandy didn’t know the sequence.

But she knew patterns. She knew the way systems told the truth by accident when they were busy. She stared at the timer, at the way the emblem flashed - arc of steel, number FORTY-FIVE - and how it repeated with a slight delay each time the chime sounded.

The chime. The timing....
