He studied under the instruction of Master Greadmo before falling to the dark side of the Force, and eventually embracing the ways of the Dark Jedi and taking on the mantle of a Jen'jidai. As a Dark Jedi, he learned the ways of sabotage, politics, and diplomacy, as he served as the Dark Jedi Order's chief ambassador and counselor, and trained under Jen'jidai Pyros and Jen'jidai Cthulu Plaga.
