What if our players' Jedi are the ones who help Luke build the new Jedi Order? That's pretty heroic in itself. Just a thought.
You're right, for sure. I gave this some thought: 10 years isn't that long, in that the oldest ones trained from birth are max 10 years old. Those who are old enough to be Jedi PCs are likely rebellion veterans or others who were at least old enough to remember the empire (let's say 20 year old PCs, or so).
Right after Endor Luke is going to be busy searching for students, let alone having fully trained Jedi ready for level 1 (rather than MC Jedi or Force-sensitive non-Jedi). If we're assuming the Movies-as-Canon stance, PCs would for sure be the first batch of Jedi Luke had trained...
That said, maybe the Masters we have access to should reflect this. One could be a reformed Dark Jedi or Sith who worked for the Emperor, and is a great lightsabre fighter/teacher. Another could be, like, an Ithorian Force Wizard who spent years in meditation on a backwater planet, hidden from the Empire.
And maybe quests could be to find a missing Master.
In terms of "Nolan", it would make sense to be part of the Imperial Remnant, giving us instant sources of conflict. Characters might be headed there to clean it up, find and support the resistance, bounty hunt, etc. There could also be Hutts supporting the remaining Imperials for their own corrupt reasons.
The system is still in Impirial Controlled space? So PC rebels could be sent in to act like Rebels, even though they're working for the fledgling Republic... I kinda like it. Do we want it totally in their space, or on the edge? I ask because we've also got to have a Jedi Temple in the same system. Also, we might even want a Republic base, or even a stronghold for Rebels somewhere... maybe hidden, maybe not.
How Impirial would be a good idea? Like, we want a presence in the system, but enough freedom for other powerful interests that PCs don't have to hide all the time. I'd suggest having a Star Destroyer in the system, able to dump Tie fighters or Stormtroopers, but it's got standing orders not to lay waste to any of the cities or stations or planets.
