Jarn Walon was a Miraluka man and a Shadow of the Jedi Order during the Cold War between the Sith Empire and the Old Republic. A powerful lightsaber duelist and practioner of the Force, Jarn posessed the rare power of invisibility through the Force, and so instead of becoming a Jedi Knight, was made a Jedi Shadow, a rare rank of the Order who were tasked with achieving covert missions that other Jedi could not. However, Jarn seemed to spend a lot of his time also on Tython, the home of the Jedi, where he would often journey the planet searching for knowledge regarding the ancient lore of the Je'daii, the first Force users.
