However, while Sajar was stationed on Quesh in 3642 BBY to guard a military base, he was caught in an Imperial invasion. Slipping back into the grasp of the dark side after killing several prisoners and being recognized by Imperial forces, Sajar decided to die a servant of the light at the hands of the Emperor's Wrath, the Sith Emperor's personal executioner, rather than become a Sith once more. However, Sajar and the troopers of the Republic Military's 86th Infantry received reinforcements when Braga sent the Jedi Knight known as the Hero of Tython to rescue Sajar. The Knight's efforts in the battle to save the base ensured that Sajar could return to the Jedi and receive redemption.
