Octavo is a musician and magician who played for the King of Hyrule. Fearing the return of Ganon, Octavo bewitched the King of Hyrule and attempted to steal the Triforce. However, upon being touched, the Triforce split. Despite this, Octavo was able to enchant his Lute and transform it into the Golden Lute, granting him more power. Using this power, Octavo sealed Hyrule Castle, cursed the inhabitants of Hyrule to follow a rhythm, and summoned an army of monsters across Hyrule. He also placed various Instruments deep within the dungeons of Hyrule to prepare Four Champions who could combat Ganon.
