Fairy Powder

Fairy Powder is a quest item obtained in. The Fairy Queen, who has been turned into an Octorok by a curse set by Veran, can be cured with the powder. The Fairy Powder is kept in the nearby Eyeglass Island Library. Using the Harp of Ages to travel between the past and present ages, Link is able to obtain the Book of Seals and use it to procure the powder from the library, and subsequently use it to cure the fairy. The Fairy Queen then cleanses the seas with her magic, curing Jabu-Jabu of his illness. Link is dubbed "Zora Hero" by the King Zora, and is permitted to enter Jabu-Jabu's Belly, the seventh dungeon of the game.
