A Jedi held the position of Supreme Commander for all Jedi troops stationed on the world of Corellia back in 3640 BBY, during the Battle of Corellia that saw the Galactic Republic clash with the Sith Empire. This Jedi fought with the Republic Military to protect Corellia, but was killed; Nae Nuuv, a Jedi who was a Sullustan, stated that her physical form was destroyed by the fighting. The Jedi Knight called the Hero of Tython took over as Supreme Commander after her death.
This unnamed Jedi commander was initially referenced in the "Jedi Commander" mission for the Jedi Knight class within Star Wars: The Old Republic, a video game that was launched by BioWare and LucasArts. Neither the name nor the species of this Jedi were provided.
