I'm building a character for a street level open-ended game who's based around a fairly basic concept: curious, bright magical researcher who refuses to give up his autonomy. He'll do a job for a fee because he made the *choice* to be so bound, but he won't put himself under someone else's authority long term, or at all without strict guidelines. This is all to preserve his status as a moral agent, able to do what he believes is right without compromising his morals.
I need to flesh him out. He uses a Greek model of hermeticism, though he suspects a Unified Magical Theory is possible and does research to that end. I'm not sure where he came from, how he ended up in the Barrens, etc. and could use some good ideas
