What would happen if a jedi reincarnated into a fantasy(er) world with magic and swords

Im done with this i can't think of how to go and it SUCKS VERY VERY BADI mean for god sake i can't even come up with a name for the guy don't get me wrong its a good idea i came up with jedi who believes both sides of the force are right yet wrong at the same time and died for that because both sides hate his belief then reincarnates into a medieval fantasy world with the hero system inventory his powers and a light saber then making another order of jedi that follows his beliefs about how the light and dark side needs to merge there can't be a yin without a ying
