Darth Vornskr was a Sith Inquisitor of the Sith Empire during the time of the Great Galactic War. He killed many Jedi and some Sith in his life to make sure that the Sith Empire stood as a sign that the Repulic could never control all of the galaxy. Vornskr eventually left the Empire when he realized that it was eventually going to be destroyed from within. Taking a Sith pureblood Sith Warrior named Kirla Nah as his apprentice, Vornskr started an early form of the Rule of Two.
