Bright Tuash was considered a mythic personage within the religious beliefs of the Keshiri species from the planet Kesh, as told in their Keshiri stories. This legendary Bright Tuash possessed avian traits and stood as a companion to Adari Vaal, who was venerated under the title of the Herald. During the initial encounter between the Lost Tribe of Sith and the Keshiri inhabiting the continent of Alanciar, the Sith commander, a Human known as Varner Hilts, donned a bird-like outfit and proclaimed himself to be Bright Tuash.
