Warbeak was a female Sparra, the daughter of Greytail and Dunwing and niece of King Bull Sparra. Though being royal family, Bull regularly forgot his promise to look after Warbeak and her mother following Greytail's death at the hands of Asmodeus, but they got along quite well, with Warbeak becoming a popular, intelligent and a powerful warrior as the years went by. Warbeak also developed the habit of identifying creatures from below as "worms". The Sparra court was renamed Warbeak Loft in her honor, and she was succeeded as leader by Sir Harry the Muse, who helped rebuild the tribe.
