Raquella Berto-Anirul is the first to ever undergo the Agony, when the jealous Sorceress Ticia Cenva poisons her. Instead of dying, Raquella's body adapts the poison, gaining access to Other Memory, turning her into the first Reverend Mother. After Ticia's death, Raquella forms the Sisterhood out of the remains of the Sorceresses of Rossak and becomes the first Mother Superior.
