Wind was one of the four android creations of the Keeper. She had the ability to manipulate wind.
The Keeper was left by her makers on the Keeper's World to restore it after it was devastated in an ancient war. To assist with this task, and to fend of her loneliness, the Keeper created four nameless android helpers. One of these was an android in female form who could control wind.
During the Battle of The Keeper's World the androids sided with Princess Leia Organa, Luke Skywalker, C-3PO, and R2-D2 against a squad of Imperial Stormtroopers. During the battle Wind knocked the Stormtroopers prone with her powerful gusts, allowing the Rebels to escape.
Wind had the appearance of a human female with long blond hair that seemed to constantly billow in an unseen breeze. She was not immediately identifiable as a droid, save for her photoreceptors, which looked like a yellow light shining from black eye sockets.
Wind was the most inquisitive of the Keeper's android creations, as well as the most willing to answer questions. She seemed to know little about life outside of the Keeper's Temple, not even knowing what parents were.
Through some unknown means Wind had complete mastery over her namesake element, creating both weak and strong gusts of wind at will. She had complete control over these gusts, and could use them to blow scattered debris, or even people.
