[i]shrugs[/i] Your concept of the Rangers was a great one. And some of us just want to play heroes...

If I had to choose someone more grey, I'd probably go with a Chiss from the Ascendancy, sent on a mission of some kind, or just lost and in a badly damaged ship. Or some trooper trapped within the First Order who either escape due to fear, or be unexpectedly rescued. Or a First Order officer that would defect from the Order after seeing too many things against her conscience.
