In the cellar of an old tenement house, Martha and Kacper find a rune-marked medallion and uncover a hidden portal. Beyond it waits a world of mist, crystal towers, and a warning that curiosity may come at a cost.
Martha swept her torch across the cellar wall. The beam caught rough brick, sagging plaster, and the pale ribs of old newspapers pressed into the dust. The air smelled of damp stone and time itself. Beside her, Kacper crouched over a round medallion he had just lifted from the floor, its surface cut with tiny runes that seemed to shift when the light touched them.
"Look at this," he said, keeping his voice low. "I've seen signs like these in a book on ancient civilisations. It's not decoration. It's a code."
Martha leaned closer and brushed one of the symbols with her fingertips. The cellar answered with a soft click.
The wall gave way with a deep, grinding rasp.
A narrow seam opened in the brick, then widened, spilling out a dim purple light that made the dust glitter like ash. Cold air breathed from the gap, carrying a scent Martha could not name, something sharp and sweet, like lavender crushed under snow. Kacper looked at her, exhilaration and fear flickering across his face.
"Are we really doing this?" he whispered.
Martha did not trust herself to answer. They stepped through together.
On the other side, they stood on a footbridge suspended over a vast abyss. Below them, mist rolled in slow, black waves, threaded with silver light. Far away, jagged mountains rose like broken teeth, and beyond them a city of crystal towers caught the strange glow and scattered it into the darkness.
The air here was colder, cleaner, and wrong in a way Martha felt in her bones. Then a figure emerged from the mist. She seemed to be made of shadow and starlight, her eyes bright with an impossible, living shimmer. When she spoke, her voice echoed not in the air but inside Martha's head.
"Welcome, travellers. You have crossed the gate and joined two worlds. But are you prepared to pay the price of your curiosity?"
Martha and Kacper froze. The bridge beneath their feet gave a sudden tremor, and from deep in the abyss came a slow, dragging sound
