Yashu-Vo

Yoshu-Vo was a Male Voss, he was part of Lord Beldiss's plan to take failed Mystics, and teach them the ways of the Sith, therefore they would not need the alliance with the Voss if they had an army of Voss Sith.

Behind the Scenes
Yoshu-Vo and the other failed Mystic's fate can be decided, they can eithier stay with the Sith or go to the Jedi, because it has not been yet said as canon, it is not said whether Yoshu-Vo stays with the Sith or not. Yoshu-Vo's name was only revealed if the player picked the Light Side choice and he later mailed the player.
