Xendor was a male Dark Jedi Master a few centuries after the formation of the Galactic Republic. Originally a member of the Jedi Order, Xendor expressed his intent to practice the dark side of the Force, despite it being contrary to Jedi beliefs, leading the Jedi to expel him from the Order. Becoming the first Dark Jedi in history, Xendor traveled into the Unknown Regions where, according to legend, he located the Kaiburr crystal, an artifact said to have had healing powers.
