Ildera was an Algar woman, the wife of Geran V - an heir to the Rivan Line - the mother of Garion, daughter-in-law of Darral and Alara, and the niece-in-law of the sorceress Polgara. She was also the aunt of Adara; Adara's mother was one of her sisters. Polgara once described her as adorable, with "a silvery laugh". She was beloved enough to get away with making ribald jokes with the sorceress.
