Nabooru's Second-in-Command

Nabooru's Second-in-Command is a character in Ocarina of Time who remains unnamed throughout the game. While Nabooru is away in the Spirit Temple, she leaves her second-in-command in charge of Gerudo's Fortress.

After freeing all the carpenters she will appear, complimenting Link on accomplishing such a task and give him the Gerudo Membership Card which allows him to walk about freely in the Gerudo Fortress and access the Haunted Wasteland.

Her counterpart in Majora's Mask is Aveil.

Trivia

 * Her clothing changes to match the color of Link's tunic--however, this seems to be a glitch, as it has been removed in the GameCube version, where her clothing remains red no matter Link's tunic.
