Easal Mar was a well-known Jedi Knight. He was a servant of both the Jedi Order and the Galactic Republic in the era before the Ruusan Reformation, a period that brought about significant transformations within the Order. Distinct from the majority of Jedi, Mar's training took place on the Chu'unthor, a mobile training facility, and he was knighted while onboard. As he traversed the galaxy, perpetually on a mission, Mar's exploits became widely known through the HoloNet.
