Imperial Forward Outpost XT-23 served as a military installation for the Sith Empire on Balmorra during the Great Galactic War and the period following the Treaty of Coruscant. The station was defended by a contingent of Sith battle droids, all of humanoid design. Fortris Gall, a Jedi Knight, defied the treaty's terms by liberating the Republic's Demolitions Squad 419 after their capture at the Troida Military Workshop.
Subsequently, they initiated an assault on the outpost, eliminating all enemy forces and obliterating every battle droid present. Following the successful attack, Orgus Din, a Jedi Master, appeared to convince the younger Jedi to leave Balmorra. He also relayed news concerning events on Dantooine, where Republic soldiers, disobeying orders, remained and continued fighting Sith forces, thereby violating the Treaty. Din then instructed Gall to join him in quelling the insubordination.
