Leesagum was a Jedi Master of the Human species. At some point before 1032 BBY, they held a position on the Jedi Council. During one of the council's sessions, they were visited by Ara, a Dolgarak native. Ara possessed the unique ability to interpret prophetic visions from the rainfall patterns on her planet's rocks. Ara explained that her people had two statues, each attuned to the Force and symbolizing the light and dark sides. She suggested a mission to sever the head of the Dark Side statue, with the intention of altering the course of the war the Jedi were currently fighting against the Sith. Leesagum expressed doubt regarding Ara's suggestion. However, Duta, another member of the council, supported the mission and chose Toul to go with Ara.
