Three friends uncover a sealed passage beneath a lunar base and a portal that should not exist.
Lunarum Station never really slept. Even at night, the corridors glowed with pale artificial dawn, and the curved windows held the moon in silence while Earth hung far away like a bright, impossible promise.
Deep below the main decks, in the underground lab, Lea sat hunched over a stack of readings, Iwo was half-buried in diagnostic maps, and Max paced between consoles with the restless energy that always made him look as if he were one bad idea away from trouble.
They had been friends since the Academy, which meant they knew each other too well to pretend boredom lasted long. Lea wanted the kind of discovery people would argue about for decades. Iwo loved systems that could be taken apart, understood, and rebuilt better. Max just wanted something real to happen.
It was Max who noticed the power spike first.
One of the auxiliary grids had flickered in a pattern that made no sense. Not a failure. Not a surge. A signal, as if something hidden inside the station had reached out and answered back.
He leaned over the display, narrowing his eyes. "That isn't on any maintenance schedule."
Iwo was already pulling up the old schematics. "It shouldn't be possible," he muttered, but his voice had sharpened with interest.
The trail led them beyond the active sectors, past sealed storage and dead corridors that had not seen foot traffic in years. At the far end of a forgotten service wing stood a warehouse with dust on the doors and warning strips so old they had faded to grey. The access panel beside it was dark.
"We could report it," Lea said, though she was already reading the lock mechanism with the focused intensity that meant she had stopped pretending to be cautious.
Max grinned, low and crooked. "And spend the rest of the night waiting for someone else to have the fun?"
The doors gave way with a complaint of metal on metal.
Cold air rolled out from the darkness beyond, carrying the smell of dust, old lubricant, and something faintly mineral, like rain trapped in stone. Behind the warehouse lay a service lift no one had mentioned in any briefing. Its doors stood open, its controls alive, as if someone had only just used it.
They stepped inside.
The descent was too long.
When the lift finally stopped, it was not at another storage level but at the mouth of a tunnel cut straight into the rock beneath the station. Smooth metal lined its walls. Symbols, thin and sharp as scratches from a blade, ran in bands along both sides. A soft blue light pulsed somewhere ahead, steady as a heartbeat.
The farther they walked, the warmer the air became. Not stifling, not dangerous yet, just wrong enough to make Lea glance back once, as if the tunnel might have shifted behind them.
At the end of it, the passage opened into a chamber so large their lamps barely reached the ceiling.
In the centre hovered a circular gate, suspended above the floor in a ring of light that breathed in slow, silent waves. Beside it, an ancient terminal still hummed, its screen the only thing in the room that looked untouched by time.
A single line blinked there in crisp white letters:
ARE YOU READY FOR DISCOVERY?
None of them spoke.
Then the gate brightened, and somewhere beyond it, something answered by tapping once against the other side.
