Slestack, a Human of the male persuasion, was employed by a clandestine crime boss. This boss was a rival of the employer of another criminal, named TuMarr. During the era known as the Cold War, Slestack and TuMarr crossed paths on the planet Dromund Kaas. Each was there with the objective of capturing Grik Sonosan, a operative from the Republic Strategic Information Service who had been brought to Dromund Kaas for interrogation by Darth Baras. The apprentice of Baras successfully played the two criminals against each other, which allowed the Imperial Commander named Lanklyn to make an escape.
