Ian Felstar was a human Jedi Knight at the end of the Clone Wars. He preferred using the backhand lightsaber technique, and was quite good at it. Near the end of the Clone Wars, an alert came to his squad to go to an obscure Outer Rim desert planet, to destroy a Separatist base. Ian, his former master and a squad of clones set out to the planet. When they got there, they found no base, just an abandoned city. The real purpose for the mission was revealed when the clones started firing at Ian and his former master. After a short battle in which many of the clones fell, the other Jedi was killed, and Ian hid in the ruined city, waiting until the clones left, then venturing out. He took a set of armor off one of the dead clones, and took his former master's lightsaber. He lived in the city, scavenging supplies and practicing wielding both lightsabers. He was eventually rescued by a Jedi who crash-landed on the planet. After repairing the ship, they flew off and hid on another planet. Ian later died after he was ambushed by stormtroopers, but not before killing many of them.
Note: I know the armor is sandtrooper, not clone, but I wanted the dirty, weathered look. His hair was originally brown, but I got the blond hair and used it to better reflect hair bleached by exposure to the sun and sand.
