@Odin If that's how you wanna go, so be it the only part I don't agree with is the how he survives Order 66. If he was with Clones then, they would know and if he was in the temple, it doesn't matter fair shootin'. If you're concerned with your IC SW Knowledge then it may actually be easier to play someone low skilled but reasonably competent. If he's too much of a fool he wouldn't have passed the trials, and if he didn't pass the initiate trials he would have joined one of the various corps of Jedi-Regects. Which is a possible route you could take.
I'm cool with him being inept but I'd rather not Jar Jar levels of inept, which is how reading that comes across. I have faith in that even with your little knowledge you could write a character that could work. If you wanna discuss more/help then feel free to PM me, or I'm sure @Renny would be willing to help.
I do also fear that, having him be incompetent, it might limit what I can actually do in terms of interesting things to do IC. I'm a little worried that I'm too unknowing in what it means to be a jedi, but I could try and whip up a more.. normal guy, and have his IC mistakes explained some other way...?
