During the battle Karr became unstable and turned to the dark side for the strength to win their fight. The Jedi Master failed and was defeated by Baras' agent. Mortally wounded, Karr felt that the dark side had underestimated him and would try to fight his way back to the light side and die in order to protect Willsaam, but Imperial operatives dispatched by Baras were able to stabilize him so that the Warrior could use him as bait to draw Willsaam into the trap. The ruse was successful and she arrived to witness her master twisted by the dark side into something she couldn't recognize as he spewed his hate for both Baras and his own apprentice. At first, she considered the possibility that Karr had been hiding this all along before she accused the Sith of corrupting her Master. The Warrior told her that the only way to find the truth was to use her power on him. Willsaam complied and saw these dark traits within Karr but refused to believe it. Confused and angry, Jaesa engaged the Sith Warrior in fair combat, but she turned out to be no match against the Sith apprentice. In the end, Jaesa joined the Sith Warrior willingly, either through corruption or persuasion on the part of the Emperor. As for Nomen Karr, his fate is ultimately up to you.
