Shon-Ju was a tall and muscular fallen Padawan-turned-cult leader who taught himself to direct the Force into his hands in the place of fighting with a lightsaber. He then went on to find other Force-sensitives to whom he taught his methods. During the Clone Wars, Shon-Ju's Force school went to Cavamina Minor to pursue the war-profiteer Attuma Duum. There they saved the Jedi Knight Aayla Secura from Duum's mercenaries, and Shon-Ju agreed to help the Twi'lek Jedi stop Duum. Shon-Ju betrayed Secura, however, and his actions led Secura to cut off his hands and allow Duum to escape. Shon-Ju ran off into the doomed headquarters and later found his way back to his students; eventually he accepted prosthetic hands, which were superior to his old ones.
