It depends on your players where do they want to go? I am just about to start GMing myself and I have gotten and written quite a few stories for the campaign (if it ever gets off the ground ). Anyway ask questions like how do they view the empire? rebels? or are they just trying to get by in this galaxy?
A few ideas that I had - they crash on/sent to investigate a moon where an early experiment of Project I71A has taken place (Death troopers, just have weaker and slower storm troopers who don't die) where they have to team up with Imperial survivors to escape who is just a few scientists, some storm troopers and a lieutenant who is open minded of others. - Altering the AoR GM kit mission (for the opener it might help to make the things a little easier)
- A quest were the characters meet a heavily pregnant woman (whose husband is no longer there) and is having troubles with things moving around her house. It will turn out that her unborn child is heavily force sensitive which then leads the party on a quest to find something to null the force (there are some things in legends that I know of and it is a galaxy maybe there is something out there)
