Darth Imperious was the Sith title and identity of Jorus Kuun, a male Kel Dor Jedi Apprentice. Born to a family of merchants, Jorus lived on Dorin for the first nineteen years of his life. Unfortunately, his parents' jobs required frequent traveling, and Jorus could not see them much. After nineteen somewhat apathetic years, Kuun was discovered by a Jedi Knight from Luke Skywalker's Praxeum. The Jedi, detecting Jorus' high Force sensitivity, offered him to be taken to the academy for training. Jorus accepted, leaving his home and family behind.
