Zavrasha, a Sith Lord belonging to the Pureblood race and identifying as Female, served the reconstituted Sith Empire as an apprentice to Darth Mortis. Her assignment on Nar Shaddaa involved monitoring the technological progress of the Republic. In that role, she instructed a fellow Imperial to discreetly and rapidly eliminate those advancements, so as not to put the Treaty at risk.
Lydia Leonard lends her voice to Zavrasha, and she also voices Lana Beniko within the game. Male player characters can engage in flirtatious interactions with her, which can potentially lead to a secluded encounter.
