Eris -Prototypal Prodigal-

It was only after the killing stopped that the memories kept going—past the lab, past the scream, all the way to the soft moments she had forced herself to erase:

Quinn asleep on a maintenance deck, curled beside a coolant pipe for warmth. Quinn printing a tiny origami crane from scrap alloy because “metal birds never forget where home is.” Quinn kissing the scar where Eris’s human ear used to be and whispering, “They can’t program love out of you. I dare them to try.”

Eris knelt in the ruin, shaking. Her hand hung useless, hydraulic fluid dripping like blood. She pressed her organic palm to her forehead, as if she could shove the memories back through the hole they’d poured from.

But the dam was gone.

She let out a choked laugh that fractured into sobs, then into something too animal to name.

The soil here was black and clotted, like something had bled into it for decades and never stopped.

Eris sat among the wreckage of Sub-Lab 6 again, legs folded, hand resting on the bent metal crane Quinn had once made. She hadn’t moved in hours. Maybe longer. Her HUD was flickering with errors. Her right optic was blind. Most of her systems were screaming for rest, coolant, sedation.

She ignored them.

The silence stretched—until it didn’t.

A whisper. "Eris?"

Her head snapped up. The voice hadn’t come from inside her auditory sensors. It had come from underneath. From below the ruin. Female. Soft. Cautious. Familiar.

No. Not possible.

She stood, slowly, stepping over twisted steel beams and cracked glass panels. The light was wrong down here. It bent sideways. Machines lay like bones, and doors she'd destroyed were... whole again. Clean.

And there—on the wall—a symbol she didn’t remember carving, yet it pulsed when she looked at it: a triangle made of thorns, with a single eye closed in the center.

You shouldn't be here.

She turned. No one was behind her.

The corridor ahead flickered between ruin and something else: a pristine hallway lined with white tile and chrome. Her old room. The sound of a kettle boiling. The scent of fake coffee.

Then—footsteps.

Small ones.

Bare feet.

Eris’s breathing caught.

She raised her blade-hand.

“Quinn?”

Nothing.

The white tile bled black again. The hallway distorted, narrowed, twisted. Her knees buckled. She hit the floor. Static buzzed in her ear. Then—

"Did you forget me?"

The voice was so close this time it might as well have been inside her. Broken.

Eris clawed at the side of her skull. Screamed.

“No. NO. You’re dead. I saw you die..."

Laughter. But it wasn’t Quinn's voice anymore.

It was something wearing it.

"Then why did you come back?"

The lights went out.

For a split second, the world turned red and black. A door stood at the far end of the corridor—stamped with a white sigil shaped like Quinn's origami crane. She tried to move toward it, but her legs were heavy, like submerged in concrete.

From behind that door came a wet, ragged breathing.

Something waiting.

Something that knew her.

And then—a scream.

Not hers.

"ERINA!!"

It was her.

It was Quinn.

But not dying. Calling. Pleading. Alive.

Eris surged forward. The corridor stretched like taffy. Alarms blared. The world split in layers—each one flashing another memory: Quinn's hands. Her smile. Her bones breaking. Her eyes fading. Her whisper—“Stay with me.”

Eris reached the door.

It slammed shut in her face.

A message scratched into the metal, written in blood, or maybe coolant:

YOU TOOK TOO LONG.

Her knees hit the floor. The world shook.

Then silence again.

She wakes back at the surface.

No door. No hallway. No voice.

But the crane is gone.

And carved into her chestplate—not scratched, not drawn, but engraved from the inside—is a symbol she’s never seen.

The eye.

Closed.

And beneath it, a name she hasn't heard in years.

Quinn Fœdus.

Quinn was a quaint, homely girl compared to the more brash and confident Erina. She liked origami and home-made food unlike the synthfood they had as rations. She always invited Erina to indulge in the human delights even after her rebuild into Eris. Eris loves her in every way and idolized her as the only one to show her kindness and affection. They were a dynamic duo together, having the highest success rate of any military individuals within the MDC's entire history. However, tragedy struck when Quinn took Eris' place for an experimental enhancement of the soul, and vanished in an ionizing flash of light. Eris blames herself for Quinn's death and repressed every memory related to her except her name, though she still rarely hears her voice echo from the depths..
