On a storm-lashed night, Lena, Igor, and Michal find a hidden passage in an abandoned city library and step toward a doorway that should not exist.
Rain battered the roof of the old city library so hard it seemed to shake the whole building. Lena, Igor, and Michal moved through the dark aisles with their phone torches low, the beams catching dust, warped spines, and shelves that leaned like tired men. It was two in the morning. They were supposed to be here for a history project. In truth, they had come for the rumour everyone treated like a joke: a secret room hidden somewhere in the back of the building.
"This is a terrible idea," Igor muttered, skirting a puddle on the floor. "We are absolutely not supposed to be here."
Lena smothered a grin. "You only say that when something might actually happen."
She swept her light across the wall and stopped on a framed portrait of the librarian who had run the place decades ago. The glass was clouded with age, and the painted eyes seemed to follow them through the dark.
Michal was already at the end of the row, half-hidden by a massive bookcase. He crouched, ran his fingers along the bottom shelf, and pulled one book free. The sound was tiny. The reaction was not.
Something clicked deep in the wood.
Then came a slow scrape, heavy and deliberate, as the entire bookcase shivered and slid aside.
For a second none of them moved.
Michal let out a breathless laugh. "So the legend was real."
The passage behind the shelf was narrow and airless, smelling of stone, damp paper, and something older than any of them could name. Their torches made thin, nervous circles on the walls as they went forward. The storm faded behind them until it felt as if they had stepped out of the city altogether.
At the end of the corridor stood a door covered in intricate patterns, like vines carved by a hand that had never learned how to stop. Lena reached for the handle. The instant her fingers touched it, a sharp cold shot up her arm, and the skin on her wrist prickled as if the air itself had turned electric.
The door swung inward on its own.
Beyond it was not a room, but a silver mist hanging where the wall should have been. Inside that mist, pieces of another world drifted and locked into place: arches without foundations, staircases that rose into nothing, bridges broken into floating fragments, all of it suspended in a geometry that made Lena's stomach tighten.
There was no floor. Only paths, narrow and shining, curling away into the haze.
"No," Igor whispered. "That is not possible."
Lena was still staring when the watches on all three wrists jerked backwards at once, their hands spinning in a frantic blur.
Michal stared down at his watch. "Are we..." He swallowed. "Are we going back in time?"
The mist moved.
A human-shaped shadow detached itself from the glowing haze and began to approach, slow and silent, while behind it an upside-down city flickered into view for a heartbeat and vanished again. Each step made the silver light pulse harder, as if the darkness itself was drawing breath.
Then the corridor behind them slammed shut with a deafening crash.
Lena turned too late. The door was gone.
The shadow kept coming.
