Miril, a Chadra-Fan female, headed the Ascendant. This cult had a deep fixation on duplicating the effects produced by the Force. At the Unyielding Heart, the Ascendant's primary temple situated beneath what would become the University of Bar'leth on the planet Bar'leth, Miril was present when the Sith carried out the slaughter of the Ascendant, a century before 4 ABY. In the course of this massacre, Miril gave her life to safeguard the Spark Eternal, preventing its capture by the Sith, by entombing it inside the temple.
