Grand Admiral Harridax Kirill, more commonly known as the Voidwolf, is one of the Empire's most feared leaders. He started his career as a brutal criminal slaver on the Outer Rim before becoming an Imperial privateer. His underworld experience made him an especially effective “dirty fighter,” but also antagonized the Imperial Navy's aristocratic officers who preferred to conduct war according to accepted strategies.
The Voidwolf cemented his position with the Empire by capturing a Jedi vessel filled with Force-sensitive children. He personally led the boarding party that killed the Jedi defenders and took the young Padawans-to-be prisoner. When he delivered this “gift” to the Sith on Korriban for training, they promoted him from independent privateer all the way to the rank of Navy commander.
