A user of the dark side of the Force, the priestess was an alien insectoid of the female gender. She was the leader of a coven known as the Presagers of Hakotei, which was located on the planet called Asusto. In order to perform a specific ritual, the priestess and her fellow Presagers brought Jedi Master Lene Kostana along with her Padawans, Dooku and Sifo-Dyas, to Asusto. During this ritual, Dooku had a Force vision, and he inadvertently employed Force lightning, which resulted in the death of both the priestess and the other Presagers.
