About this creation
Even Piell was a Lannik Jedi Master around the time of the Clone Wars. He stepped down from the council during the war due to his age, his vacant seat was taken by Anakin Skywalker. Initially Piell survived Order 66 and went into hiding in the lower levels of Coruscant.
However Piell was eventually found and was wounded by a grenade, he died of his wounds shortly afterwards.

Cool, but I'm not sure if that's actually what happened to him or not.
Thats because the Clone Wars tv show had him die in a completely different way which would mean that a whole load of stories now just didn't happen. No ones sure how he died yet but im sticking with this one... :D
