Three teenagers find a hidden portal beneath the forest floor and step into a reality that should not exist. Once they cross over, something in the dark begins to follow their trail.
Lena, Michal, and Paulina knew the forest around their village better than most people knew their own streets. That was why the place felt wrong the moment they left the path. The August heat had thickened the air, and the light under the trees came in pale, restless sheets. Even the birds had gone quiet.
Lena led the way, a compass in one hand and her phone in the other, recording as she went. "We’ve gone farther than usual," Michal said after checking the map on his screen. "If we keep north, we should hit that old clearing my grandfather used to talk about."
Paulina pulled a face, but she was already walking faster. "The one where those treasure hunters disappeared?" she said. "You had to bring that up."
"You’re the one who looks excited," Lena muttered, though she was smiling too.
Then her boot caught on something hard beneath the moss.
She stumbled, swore under her breath, and knelt to brush away the damp green layer. Metal surfaced slowly, round and dark, too smooth to belong in the forest. Strange markings spiralled across it in thin, weathered lines. A faint blue light throbbed beneath the grime, as if the thing were breathing.
Michal crouched beside her. "That is not a normal cover."
Paulina reached out before either of them could stop her. Her fingers touched the cold metal.
The ground shivered.
A low rumble rolled through the soil, deep enough to vibrate in Lena’s teeth. The disc answered with a soft click, then slid open in silence, revealing a spiral staircase dropping into a blue glow that seemed to come from nowhere and everywhere at once.
Lena raised her phone, the camera already recording. No one spoke. There was no sensible reason to go down, which was exactly why she stepped onto the first stair.
The air changed immediately. It was colder below, metallic and dry, carrying a faint scent she couldn’t name. The steps curved down farther than they should have, disappearing into a light that pulsed with every heartbeat.
At the bottom, the three of them stopped.
They stood in a vast chamber lined with frescoes so old the figures on them had almost worn away. In the centre of the hall, a column of light burned upward from a floor carved with the same strange symbols as the door above. Crystalline pillars rose all around them, sharp and clear as frozen flames, catching the glow and scattering it in shards of colour across the walls.
For one breathless second, Lena thought they had found something impossible and beautiful.
Then a metallic scrape echoed behind them.
All three turned at once, but the light flared so violently that Lena had to shut her eyes. The chamber seemed to tilt. Somewhere in the haze, something moved, dragging across stone with a deliberate, patient sound.
Michal grabbed Lena’s sleeve. Paulina let out a sharp gasp.
A whisper slid through the chamber, thin and close and utterly unfamiliar, as if the darkness itself had spoken their names.
