Zasha Thax was a Human female captain in the navy of Revan's Sith Empire during the Jedi Civil War. Originally a lieutenant in the Republic Navy during the Mandalorian Wars, she decided to join Revan after fighting alongside him during the conflict. Under his regime, Thax became a captain and commanded the Oppressor, a Centurion-class battlecruiser. It was eventually placed under command of Grand Admiral Hasek Grunger. Over time, the two became close, and it was rumored by the crew that they were romantically involved (though this was unproven). She, along with Grunger, was killed during the Battle of Rakata Prime, when a Republic starfighter crashed into the bridge of the Oppressor.
