Darth Messavikki was Sith Lord from planet Kauch that found Lakunoch Facility, cloned Momko Dva's body and found Tomb of Youth. He was like a father to Momko's clones and trained them well. Making his own little empire, he became very good strategist and teacher. At the time of Galactic Empire, he wanted to stop Palpatine's politics and Darth Vader's arrogance and built new Sith Empire where he could openly train his sith apprentices and spread Siths across the whole galaxy.
