Krelk served as a Chieftain of the Askhew people on the planet of Entooine. This occurred during the time of the Galactic Civil War. A-3P0 was the one who introduced him to a band of Rebels, and Krelk secured their agreement to aid him in his efforts to thwart Jowart Typok's hunting of the Blue banthas. He went with the Rebels as they left their base, and encountered two adult banthas that were missing their horns, and a young bantha. Using the lower leg bone of a typical bantha, he was able to communicate with the young blue bantha. The bantha let him know that the hunter was nearby.
