They'd get a ship pretty much immediately, which I'd need to define (nothing great, kinda a junker)
either as Jedi or 'support personel' like pilots or soliders or whatever. I would be forcing class right off the bat. I don't currently have a reason for a NPC Jedi Master to go on a field trip with some apprentices. Actual start of the campaign, running from the Imperials, assisting other jedi, trying to learn the whole Jedi thing without a master. Order 66 happens and everything goes to hell forcing the Pc's to bail from the situation right quick. They'd also have a small contingent of clone troopers.
Essentially some sort of mission with a NPC Jedi master and some lesser jedi First adventure occurs just before / during Order 66. I'll post it in point form to to expedite getting my ideas into a forum post. I've got an idea that I need help fleshing out.
