Oracle

The Oracles are three female dancers: Din, Nayru and Farore, all of which star in and. Nayru is the Oracle of Ages, and Din is the Oracle of Seasons, eponymously named after the respective titles of the two Oracle games. Farore, the Oracle of Secrets in the cancelled third game of the planned trilogy The Legend of Zelda: Mystical Seed of Courage, plays a very minor role in the Oracle games, giving her passwords to obtain special items if you are playing a linked game.

Din
Din, the Oracle of Seasons, is fated with keeping the world's climatic order in balance. When Din is kidnapped and forced into a crystal prison by General Onox, the seasons go awry and change at the slightest notice.

Nayru
When the body of Nayru, the Oracle of Ages, is taken over by Veran, she uses her power to go back in the past and change the history of the land and its culture; by her willpower, she informs Queen Ambi that she must build a black tower which will benefit the land and create a national spire that other lands will respect. In truth, Queen Ambi wanted to build it so she could see her love coming back from sea.

Farore
Farore always stayed in the Hall of Secrets, only talking if you needed to inquire about secrets from the linked game.

In
They also play a small role in The Minish Cap, as traveling vagabonds in search for permanent residence in Hyrule Castle Town. Link can fuse Kinstones with all three, but only the first two fusions land two of the travelers permanent homes in the town. If Link fuses Kinstones with Din, he can meet her in her house nearby and receive Din's Charm from her as a reward for the creation of her permanent residence. Farore will yield Farore's Charm, and Nayru will present will present Link with Nayru's Charm if either of them are presented wtih houses, as well.
