Hareth, a Sith Pureblood woman with the rank of Colonel, was part of the Imperial Military under the reestablished Sith Empire. She was the romantic partner of Executor Krannus, another officer in the Imperial forces, and also belonged to Krannus's death cult, which venerated the Sith Emperor. In the time of the Galactic Republic and the Empire's revived conflict, Hareth went with Krannus to the world of Belsavis for the purpose of the cult obliterating the planet, thus fulfilling the Emperor's desires; she willingly gave her life to delay the Hero of Tython, a Jedi Knight, to allow Krannus to finish what they had set out to do.
