Ilith's Group, a breakaway division from the Ascendant cult, was founded many centuries preceding the Galactic Civil War. Their purpose diverged from that of the Bar'leth Group's leader, Miril, focusing on alternative research avenues. They journeyed to Pyrr IX, constructed an Ascendant temple mirroring the one located on Bar'leth (Ascendant temple), and were subsequently governed by Ilith. Ultimately, the Sith annihilated the entire group.
