Stark, a Sith belonging to the Sith Empire during the Cold War, was a male Human. His efforts to uncover the secrets of the Children of the Emperor led to his capture and subsequent brainwashing by the First Son, transforming him into a devoted follower. Subsequently, in the vast expanse of space, he abducted Senator Tobas Grell, resulting in the deaths of three guards. He questioned the Senator regarding the Rift Alliance's strategies, ultimately killing him due to his refusal to cooperate. Afterward, Barsen'thor and Nadia Grell, Tobas' daughter, boarded Stark's vessel to face him and rescue Tobas. Upon discovering her father's demise, Nadia, filled with fury, battled Stark and, with Barsen'thor's assistance, emerged victorious. Barsen'thor then either permitted Nadia to avenge her father by killing Stark, or convinced her to refrain from doing so, leading to Stark's death from his injuries after stating that his master is "sending me away again".
