Lieutenant Major Pirrell, a male Human, held a position as an officer within the navy of the reestablished Sith Empire throughout the Cold War. In the course of the Battle of Balmorra, he functioned as both the assistant to the naval attaché of Balmorra's governor and as the chief of intelligence for Imperial military units stationed on the planet.
He employed an Imperial bounty hunter with the aim of outperforming his superior officer, Colonel Sartius, and to gain favor with Admiral Ivernus. Unbeknownst to him, this bounty hunter was actually a participant in the Great Hunt, with Ivernus as their intended target. Pirrell directed the bounty hunter to sabotage Sartius's assignments, prompting Ivernus to personally travel to the planet not to promote Pirrell, but to execute him. The hunter then seized this chance to assassinate Ivernus.
Upon discovering the hunter's real motives, Pirrell tried to flee, but the hunter ultimately killed him.
