Bonmu is a remote tropical isle located in southeastern Minata.[1] Formerly part of the ancient, long-vanished Taumata civilisation, Bonmu is now uninhabited and home to only various species of hostile flora and fauna, including dinosaurs. In 4721 AR, the organisers of the Ruby Phoenix Tournament chose to host the tournament's first-of-its-kind pre-qualifier on Bonmu, which was dubbed Danger Island for this event.[2]
