Sariss, alias Prophetess, was a Force-sensitive female Human who was one of seven Dark Jedi attempting to reclaim the Valley of the Jedi some time after the Galactic Empire's defeat at the Battle of Endor.

Born the daughter of Imperial Warlord Cronal, Sariss was trained in the ways of the Force by the Prophets of the Dark Side on Dromund Kaas. As she grew up, she became an apprentice to Inquisitor Jerec, who completed her training as a Dark Jedi. She was one of Jerec's most loyal followers.
