[@pyroman] To quote Dooku here. "...You are not Sith. You wear the trappings of the Sith, you fight like the Sith… but this can be imitated, however. You lack a vital quality found in all Sith. Sith have no fear, and I sense much fear in you." The fear part maybe not but during this time the force sensitives were Shadowtroopers or Inquisitors. She could just have escaped the Empire or maybe she learned her skills on Korriban from Sith holocrons?
