Leeds held the rank of Senior Lieutenant and served on the Interrogator.
As Jovan Vharing, his commanding officer, was asleep, Leeds detected a signal originating from the planet Qlothos, which corresponded to an outdated Rebel transmission code.
Believing it to be a hidden Rebel base, the Imperial forces dispatched a squadron of TIE Bombers with orders to destroy it; however, the planet's atmospheric conditions interfered with the missiles' guidance systems, causing one to miss its target and inadvertently kill approximately sixty high-ranking Imperial officers in a housing area.
Vharing was personally executed by Antinnis Tremayne as a consequence of Leeds' error, and Leeds was subsequently relieved of his duties, with Waleran taking his place.
