Background
Raised on Coruscant, Jason had seen the worst of the galaxy but also the best. He had learned how to keep to the shadows and remain unseen rather than being out in the open. Of course, a few of those skills thankfully transferred to hiding within a crowd. It was from a comparatively older age that he had been taken into the jedi order to learn to harness his gift of the Force. It had been a rough upbringing, and the Clone Wars had helped temper his skills and anger.
It wasn't until Order 66 occured that the young jedi fled to a desolate planet and remained hidden, never once using the Force or his lightsaber. He had learned how to shoot and survive while still falling back on his old techniques of seeing what information he could gather about the Empire. The news was rather dire as it seemed two Sith had arisen and one was currently in control of the New Order. That was when he knew he had to return from hiding and show this Emporer that the not all the jedi were executed. Of course, his first problem would be getting off the rather lethal planet of Stoga in one piece. The rest would have to eventually fall into place.
Motivation
Jason stands by the belief that the Force is to be used to keep balance in the galaxy. With the rise of two Sith Lords, he feels he must step in to once again find balance in the Force.
