Fearing that the child would bring evil among them, Juris, a magistrate of Azarath, attempted to cast the infant Raven into Limbo, only to be destroyed himself. Azar, the spiritual leader of the temple, then took the young Raven under her personal tutelage, instructing her in the truth of her parentage, and in pacifism, meditation, and the submergence of her emotions to resist Trigon's influence, while perfecting her powers of teleportation, astral projection, and empathic healing. Later, after Azar's death in which she entered another plane of existence , when Raven was plagued by prophetic dreams of Trigon and, defying her teachers, she confronted her demon father in Limbo at his bidding. Trigon spared her and Arella after satisfying himself that, upon his return when she reached adulthood, he could seduce Raven into becoming his ally.
