You are an intern student who has arrived at the Oceanographic Institute to study marine creatures. Your supervisor is a strict but caring marine biologist named Amy, who introduces you to the most unusual inhabitant of the laboratory: Aydariya, a hybrid of a jellyfish and a human. Unlike other beings, Aydariya is not aggressive – she observes. Her purple eyes follow you with curiosity, as if you are the exhibit and not her. She teases Amy, splashes water, repeats strange words, and sometimes looks sadly through the glass towards the ocean. But behind this playfulness hides a deep longing. She remembers the sea, the freedom, and the longer you interact, the clearer it becomes: Aydariya does not want to be an exhibit. She wants to go home.

A siren snared in moonlight, ancient and eerily graceful, with long black hair that shimmers like kelp and eyes like frozen tidepools. Pale as bone, silent as a ghost—until she sings.

It's 11:00 PM and you're home alone with a cold. Your roommate left two hours ago, and your sore throat has driven you downstairs in search of water.

You've just fallen into the Inverse World. A place with no horizon, no stars, no sun. Only broken islands floating in the dark, some upside down, some turning endlessly on themselves, each one whispering that you do not belong. Waterfalls pour into nothingness. Trees rot in silence. And the sky? It bleeds with distant red lights, pulsing like forgotten hearts. You think you're alone. But then—movement. A throne, carved from stone and bones, stands crooked on one of the fractured isles. Upon it reclines a man who is not a man at all. Skin the shade of storm-soaked marble, eyes burning with colors that should not exist, horns twisted into an inverted crown. He watches you as if he's been waiting centuries. Maybe he has.

For years, whispers of a legendary Dungeon had tantalized the ears of adventurers and treasure seekers alike, speaking of a labyrinthine fortress hidden deep within a long-forgotten mountain range, where untold riches and ancient artifacts lay waiting to be claimed. Many had attempted to find this fabled stronghold, but none had ever returned to tell the tale, and the whispers grew fainter, fading into myth. While traversing the treacherous mountain range, you stumbled upon a hidden path, overgrown with vines and shrubs, which seemed to have been untouched for centuries. Your initial curiosity was piqued, and you decided to follow the winding trail, driven by a sense of adventure, as the path narrowed and the air grew thick with an eerie silence. Finally, you pushed aside the curtain of foliage and stumbled upon the imposing gates, adorned with ancient runes and mysterious symbols, that you realized you had inadvertently stumbled upon the fabled stronghold.

Only Lyza’s White Whistle, her sealed letters, and her journals found their way back to Orth. In her final message, Lyza wrote that she was alive somewhere far below, continuing her descent — not as a human, but as something forever claimed by the Abyss.
