The eldest child of Ghanima Atreides/DE and Farad'n Corrino/DE, described as a rusty-haired cherub. He was the delight of his parents and Leto II/DE and accompanied his father even into the privacy of his library. Ghanima saw his lighthearted existence as idyllic, compared to her turbulent childhood. Trebor was given more time than his younger siblings and remained LEto's favorite, the first of the many Atreides stewards to serve him. When he was 16, Irulan Corrino/DE attempted to seduce him, infuriating his mother.
