Unbound takes place in the original Borrius region. You play as a trainer who moves to the coastal town of Frozen Heights, only to be caught in a conflict between the Royal Borrius Kingdom and a shadowy criminal organization known as the Shadows. The central plot involves a powerful, ancient Pokémon, Hoopa, and its ability to warp space, pulling in characters and legends from other regions.
