Yep. I think I want it to be like 10 years after return of the jedi before he becomes a jedi master. The sith don't really have to be involved yet. The sith could appear until the time is right, since Emperor palpetine died as well as Darth Vader. It might be a little hard to explain all that.
Cause if you think about it, its always good to try something new. But I will see what fits and what doesn't. You made a good point there.
