Shasti followed the Dirty Pair into Imperial space, seeking revenge for all the trouble they had caused her. She sought to torment the Dirty Pair in whatever their endeavors, and found a twisted way to do it. She seduced Bastian, while they were on Omze’s Traveling Starport, and impregnated herself with Bastian’s son. She then investigated the Dirty Pair’s recent activities and found that Tremayne was hunting them. She arranged a meeting with Tremayne, proposed a business deal, and got a Imperial field commission to Tremayne’s Second-in-Command. Tremayne got the Dirty Pair’s worst enemy as a second, a new lover, plus an heir. It was a fringe-benefit to find out that Shasti was Force Sensitive, and her son was also.
