by several individuals in their quest. After finding all the Masters, the Exile travels back to Dantooine and learns that the countless deaths at Malachor V resulted in the Exile unconsciously giving up their connection to the Force, which then became the teachings of the new Sith. If the player aided the Jedi Masters, they prepare to strip the Exile of their Force connection permanently, as the Masters fear that these teachings could result in the actual death of the Force, but Kreia reveals herself to be the former leader of the Sith and murders them all in retribution. If the player killed the Jedi Masters, Kreia attacks the Exile and leaves. Tracking Kreia to Telos, the Exile fights and defeats a corrupted Atris, from whom it is learned that Kreia plans to strengthen a massive "wound" in the Force made ten years prior. This "wound" had been created by the Exile during the Mandalorian Wars, when they activated a gravitational superweapon, the Mass Shadow Generator, in order to end the battle on the planet Malachor V, causing mass death and destruction. Before following her to Malachor V, where Kreia had since rejoined the Sith as Darth Traya, the Exile stops a Sith invasion of Telos, defeating one of Traya's former apprentices, the Sith Lord Darth Nihilus. On Malachor V, the Exile is separated from their companions and fights through hordes of monsters on the planet's surface and the inhabitants of a large Sith Academy who survived the cataclysm. On the final floor of the academy, the Exile kills the Sith Lord Darth Sion and confronts Darth Traya in the planet's core. The Exile defeats the Sith Lord, but before Traya dies, she delivers a prophetic vision of the future pertaining to the player's companions and the worlds that were visited over the course of the story. Depending on the Exile's alignment, they either order the destruction of Malachor V, escaping before it is destroyed, and travel into the Unknown Regions in search of Revan (light side), or remain on Malachor V as the new Dark Lord of the Sith (dark side).
