The Priestess was a female insectoid alien and a user of the dark side of the Force who led a coven of the Presagers of Hakotei on the planet Asusto. The Priestess and the other Presagers led the Jedi Master Lene Kostana and Padawans Dooku and Sifo-Dyas to Asusto in order to undertake a ritual. Dooku experienced a Force vision, and unintentionally used Force lightning to kill the Priestess and the other Presagers.
