Jastal, a Human male commander within the Imperial Guard, served the reconstituted Sith Empire throughout the Galactic War. During the Battle of Corellia, Darth Charnus assigned Jastal the duty of acquiring the Hull Cracker weapon from the Czerka Corporation. By pointing an Imperial-aligned operative towards Brall Tavar, the Czerka representative on Corellia who possessed the activation codes, Jastal aided in the mission's success, allowing him and his troops to secure the Hull Cracker itself.
