Which side would he be on? Rebel? Imperial? (Since he is going to be friendly, I don't see why he would be an Imperial. It's your call)
Your character could be farming in Evergreen meadows, and then one day a Resister arrives at your farm and asks you to join them. You say you would think about it. The next day, an imperial comes to enlist you. You tell them the same thing. (Do you want me to keep going or is this not what you had imagined...?)
