Augustus Primus Leonus was a male Human Jedi Master who served as the Battle Master and a Jedi High Council member of the New Jedi Order just prior to the Third Galactic Civil War. Years before the war, he and Elkaid rescued a boy from Lacrima. During the eve of the war, he resigned as Battle Master following a vote of no confidence against Grand Master Beric Kanasur and Prime Envoy Bacilla Kane, the former of whom was a close friend of Leonus.
