Lord Keran was a male Sith Lord who served Empress Shira during her reign of the Stellar Imperium. He was regarded as the weakest of the Sith Lords and frequently kept on military assignments. He was responsible for quarantining the Doldur Asteroid Belt after the Dantooine Virus had spread to there from Dantooine. Keran's fleet was mostly successful, but there were two notable failures. First, Alema Rar was not prevented from reaching the asteroids, and although she died, she was still able to send several reports back to the Jedi about what she found there before her death. Second, three refugees did escape the asteroids, which continued the spread of the virus.
