Veran

http://www.zeldauniverse.net/images/stories/games/z8/characters/veran.gif

Veran is the evil Sorceress of Shadows from the game Oracle of Ages. She, like Onox, is used by Twinrova, but her goal is to fill the land of Labrynna with sorrow. She succeeds in her goal by possessing Nayru, the Oracle of Ages, and Queen Ambi. Even though Link defeats her, her purpose is still served, leading to a much greater problem for Link.
