Three students slip into a sealed wing of Kopernik High School and find an iron door that opens onto a place where ruined buildings float in impossible light.
It was meant to be an ordinary June evening. The last of the sun still clung to the windows of Kopernik High School, and the only sounds in the emptied corridors were the muffled steps of teachers clearing away the end-of-year chaos.
Lena, Dawid, and Maks had already grown tired of the speeches, the handshakes, the forced smiles. They wanted something that felt real. So when the school librarian mentioned a bricked-up wing in the old building, they exchanged one of those glances that meant trouble and started looking for a way in.
The courtyard was half-swallowed by wild ferns pushing through cracked concrete. They crossed it in silence and slipped into the shadow of the old cloakroom, where dust hung in the air like breath held too long. Maks ran his fingers over the wall, grinning. “There’s supposed to be a staircase to nowhere back here,” he whispered.
Lena switched on her phone torch. The beam skimmed over damp brick, torn cobwebs, and then stopped. Just above the floor sat a narrow iron door with a round, tarnished lock, as if it had been built for something smaller than a person.
A blue light began to leak through the seams.
Not bright. Not warm. It was cold and deep, as though it came from somewhere underground and far away at the same time. Dawid frowned, then reached into his pocket and pulled out the old key he had picked up earlier from the school grounds. He had laughed when he kept it. Now none of them did.
The key slid into the lock as if it had been waiting for it.
The door opened with a long, reluctant groan.
Beyond it was no corridor, no cellar, no hidden room. There was only an immense open space stretching into darkness, filled with floating islands of ruins above and below them: broken classrooms, cracked towers, collapsed bridges, fragments of stone lit by shifting veils of blue and silver. It looked like pieces of different worlds torn apart and left hanging in the air.
Then Lena saw the shadow moving in the distance.
Too tall. Too thin. Almost human, if human things could stand that still.
The key in her pocket gave a sharp, sudden twitch, like a pulse against her leg. The floor beneath them shivered. “Maybe we should go back,” she said, but Dawid had already stepped through the doorway, and the island under their feet began to drift.
