My main character trained his whole life to be an exorcist, but ended up failing the maximum amount of times required to become one when the time came. Years passed and he decided to give up and live a normal life. Right before he leaves his hometown he gets attacked by demons and awakens to a unique power that is explained how later in story. Anyways someone finds him and explains how he isn't the only one with these powers and should join him. What I'm trying to figure out is why would he join the group? My character has no vendetta for any bad guy, no wish that needs granted, or anything like that. He was pretty much about to go to college on a scholarship and start the rest of his life. Why would he throw that away to go back to a life that has shut the door on him? One more thing it has to be of his own free will.
