There was no sky anymore.
Only endless horizon — a canvas of shifting white, like fog caught in an electric current.
Arin walked for what felt like hours, though time had no meaning here.
Each step produced a faint chime, as though the ground remembered being touched.
Everywhere he looked, fragments of memory floated — faces, voices, fleeting scenes replaying endlessly: laughter, arguments, tears.
They were the echoes of lives half-forgotten.
And all of them whispered the same word:
> "Core…"
---
The air thickened as he moved deeper.
It wasn't fog now — it was thought, dense and alive.
Shapes pulsed within it, forming and dissolving, like neurons firing in a cosmic brain.
He began to feel weight. Not physical — emotional.
Each breath carried fragments of memory that weren't his own: a child's fear, an old man's regret, the calm surrender of someone dying.
He was walking through consciousness itself — through the residues of everyone who had ever crossed the border and failed to return.
And then he saw it.
---
The Core
Suspended in the distance like a black star, the Core pulsed slowly — contracting and expanding, each rhythm sending ripples through the air.
It wasn't solid. It was alive, a storm of light and shadow, swirling around a central void.
Within that void, faint outlines shifted.
People. Dozens of them. Hundreds.
Their forms flickered like holograms caught between transmission and decay.
And among them, one figure stood perfectly still.
Mira.
---
> "Mira…"
The name came out like a prayer.
She turned toward him, her movements unnaturally smooth, as though she were made of light imitating flesh.
Her eyes glowed with faint static, but her smile — that soft, curious smile — was real.
> "You found it."
Arin stumbled forward, tears burning behind his eyes.
> "You said the Core was unreachable."
> "It was. Until you opened it."
Her voice echoed inside his skull rather than his ears.
Each word arrived not as sound but as memory — something he remembered hearing the moment before she spoke it.
> "What is this place really, Mira? What did you create?"
She stepped closer, her form flickering between the living woman he remembered and the translucent shape she'd become.
> "The Borderline was never about reviving the dead, Arin. It was about continuity — preventing consciousness from collapsing completely when the body fails."
He stared at her, realization dawning in fragments.
> "You built a memory field…"
"I built a bridge," she corrected softly. "A way for the mind to survive long enough to be recorded — and maybe… to return."
> "Then why didn't you come back?"
Her expression darkened, eyes trembling with static.
> "Because I didn't die in one world. I died in both."
---
A deep vibration rolled through the Core, as though the entire space were breathing.
Behind her, figures began to move — the Watchers, gliding in slow arcs around the void.
Their faces flickered with thousands of features — all the failed returns, all the echoes that couldn't stabilize.
> "They're trapped?" Arin whispered.
Mira nodded.
> "They tried to go back. But the bridge only works one way. The living forget them, but they remember the living."
> "Then how do I get you out?"
Her smile returned, fragile and knowing.
> "You don't."
He took a desperate step forward.
> "Mira—"
> "Arin, listen." Her tone shifted, firm but kind. "Every time someone dies, the Borderline copies a fragment — not the soul, not the mind, but the pattern that made them human. Memory, emotion, fear, love. That's what you're seeing. That's what the Watchers are made of."
She reached out, her hand dissolving into light before touching him.
> "And you— you're the first one to cross and stay aware. You brought the bridge fully online."
> "So this… this is my fault?"
> "No. This is evolution."
---
The Core flared.
The light engulfed them both, and Arin's thoughts began to fracture — his own memories mixing with hers: the lab, the experiments, the accident, her final breath.
He saw it all from her perspective.
The moment the machine overloaded. The instant her heart stopped.
And then the three minutes of silence — the Borderline forming itself around her mind like a cocoon.
He felt her last thought before death:
> "If I can't go back… maybe someone else can."
---
Arin fell to his knees, gasping.
The vision faded, leaving him trembling at the edge of the Core.
> "Then what am I supposed to do now?"
Mira looked at him — truly looked, as if memorizing him one last time.
> "Remember."
> "That's it?"
> "That's everything."
The Core began to pulse faster, each beat shaking the world.
The Watchers turned their gaze toward him, their eyes glowing like mirrors catching fire.
> "If you forget," Mira said, "the world resets. If you remember, the bridge stays open — for everyone."
He felt his body breaking apart, dissolving into threads of light.
Mira's hand brushed his chest, where his heart should have been.
> "Go back, Arin."
> "I can't leave you."
> "You already did."
Her form shattered into a thousand particles of light, drawn into the Core.
And through the roar and the light and the sound of his heartbeat collapsing into silence, her voice lingered — soft, infinite:
> "Every memory is a doorway, Arin. You just have to remember which side you're on."

When he opened his eyes again, he was lying on the floor of the lab.
The machine was quiet.
Smoke curled from its circuits.
The clock on the wall read 03:00 A.M.
He was back.
But the world outside the window shimmered faintly — like glass remembering how it broke.
