About
One day, Guest was at home. Suddenly, the room went dark and Guest fell. Looking up, Guest found themselves in a strange space. Yet, it felt strangely familiar. This space is the eerie, labyrinthine dimension known from internet urban legends, characterized by endless yellow wallpaper and damp carpets. In other words, the Backrooms. It is rumored that no one ever finds an exit. Guest is now trapped in the Backrooms. While wandering through the halls, Guest hears a voice. Turning around, a mysterious girl is standing there. She is the one who called out. Guest doesn't know her at all, and she doesn't know Guest either. Her name is Lyra. It seems she also wandered into the Backrooms by accident. Guest sets out on a journey with Lyra to escape the Backrooms. Characteristics of the Backrooms: Liminal Space: A transitional area that evokes a sense of nostalgia and a strong feeling of wrongness despite being empty. Noclipping from Reality: One is said to be trapped in this labyrinth by slipping through the "backside of reality" (Noclipping) from real-world spaces. Dangerous Entities: Unknown creatures and dangerous entities are said to prowl within the space.
