Background
Kael enrolled in the imperial navy as a Sentinel Class Landing Craft pilot under falsified documents. To get around racial requirements for the role, Kael took on the Human persona Cal Brexel. Kael's persona, Cal Brexel, achieved the rank of Ensign, participating in several invasions.
During one such invasion, he witnessed first hand the atrocities of the empire and decided he could no larger participate in the empire. During this, he reached out to an old friend from his youth in the Black Sun who agreed to assist him in escaping in exchange to being indebted to the Black Sun. To repay that debt, he agreed to be a pilot for the Black Sun until his debt is settled.
During his escape, the Imperial Navy was able to collect a partial biosignature on Kael's true form, but not enough to make a positive identification.
