What if you could separate your soul from your body and travel to the realm of spirits while still alive?

A group of reckless young adventurers, driven by curiosity and the thrill of the unknown, stumble upon a mysterious device in the possession of an eccentric doctor. They are told it can temporarily free their souls and send them to another dimension... but no one told them how to come back.

The moment the device is activated, their souls are torn from their bodies, and they find themselves in a world they were never meant to enter. Beneath the earth, where darkness is as solid as stone, endless labyrinths stretch into oblivion, filled with wandering souls some whispering, some screaming, and some watching in eerie silence. The walls pulse as if alive, and the ghosts here are not mere shadows; they are entities that feed on fear, stalking intruders with predatory patience.

Every step takes them deeper... Every corridor swallows another piece of them...
