About this game

This is a living, online universe where your Original Character (OC) comes to life. You don’t just play a character here—you make one. Design your character, shape their identity, and send them into a world built for exploration, chaos, creativity, and connection.

Across various distinct worlds, your character will learn to survive the neon metropolis, get lost in the withering woods, or step into places that were never meant to be explored... Every choice you make — how you look, where you go, what you collect—helps define who your character becomes.

At its core, this game is about self-expression and discovery. Whether you’re here to customize endlessly, chase lore, flex your collection, or just exist in the world with other players, there’s always something new unfolding around you. Whether you're a lone wolf, or you thrive in communities, there is a unique path unfolding just for you.

This mobile playtest is just the beginning. Things may change, evolve, or break (that’s part of the fun), but your journey starts now.

Create your OC.
Pick a world.
And step into an adventure that grows with you.
