Leo and Lena break into an abandoned workshop after school and uncover a hidden plate that tears open a passage to another world.
Leo checked his phone again and locked the screen before the light could spill across the workshop floor. The darkness in the abandoned hall felt dense, almost alive, swallowing the last scraps of daylight that slipped through broken panes overhead. Every sound carried too far in the empty space: the scrape of a shoe, the soft rattle of loose glass, the quick breath he wished he could slow down.
Lena moved beside him, a half step ahead and grinning like this was the best idea anyone had ever had. "We are absolutely going to get caught," she whispered.
"Only if we make enough noise," Leo whispered back, though he had no real confidence in that.
They had come because of a post on a local forum, buried under jokes and fake warnings. One line had been different enough to stick in Leo's head: You can find something in the old hall by the tracks that should never have been there. It had sounded like a dare. Or a trap. Either way, it had been enough to drag them here after school, slipping through a side door that should have been locked but wasn't.
Their shoes crunched over shards of old glass. On the nearest wall, Leo's phone beam caught a mural half-hidden beneath peeling paint. A faceless figure stared back from the wall, painted in long streaks of grey and blue, its hair drifting around its head like smoke. The eyes were missing. That somehow made it worse.
"That wasn't here on Monday," Lena said.
Leo was about to answer when the air changed. It grew colder near the centre of the hall, colder and heavier, as if the room had taken a breath and was waiting to exhale. He followed Lena farther in, though every instinct told him to turn back. Then she stopped so suddenly he nearly walked into her.
"Leo. Look." She crouched and brushed dust from the floor.
Under the grime was a metal plate set flush into the concrete. Strange marks ran across it in a ring, too clean to be rust and too precise to be random scratches. Leo leaned closer, and for one brief second the symbols seemed to flicker, as if they were catching a light no one else could see.
Lena touched the plate.
Blue light burst upward so hard Leo flinched. The floor lurched beneath him. The workshop, the broken windows, the mural, the smell of dust and damp concrete, all of it twisted at once into a blur of cold fire and spinning shadow. He grabbed Lena's hand as the world folded in on itself, and the last thing he heard was the sound of something opening very far away.
Then the ground steadied.
Leo stumbled and nearly fell against rough stone. Wind slammed into his face, sharp with salt. When he looked up, the workshop was gone.
They were standing on the edge of a cliff above a black, endless sea. Three moons hung in the sky, pale and close enough to make the clouds look thin as smoke. Somewhere beyond the rocks, something answered the wind with a deep, rolling cry that made Leo's stomach tighten.
Lena's fingers dug into his arm.
Leo was still staring at the horizon when the rocks behind them shifted.
Something stepped out of the shadows, tall and wrong, with too many joints moving under a skin that seemed to catch the moonlight in strange flashes. It did not rush them. It only tilted its head, as if it had been expecting them all along.
Lena squeezed Leo's hand harder. "Do you see the same thing as me?"
