Disciple of Thought
You have always been fascinated by the concepts of thought and individuality. You might have taken an interest in the Minds of the Great Intelligence at some point. However, a few years ago, you encountered a travelling hermit, a member of the Brotherhood of Thought who introduced you to the tenets of this cryptic alliance. The hermit also told you of a place called the Temple of Lore, which is run by the Brotherhood. You decided to travel there and learn all there was to know of the organization.
If you were a member of the Coop, they would not accompany you because it was too close to the City of Cartoons, a place the Coop once had a disastrous experience with. So you travelled there on your own, or perhaps with a small group of companions. How long you remained there is up to you, but you learned much during your time there.
Unfortunately, your interest in the Brotherhood of Thought has made you very unpopular with Zayd Fana (or, if you are not currently a member of the Coop, will do once he knows of your beliefs). Although there is no animosity between the Minds of the Great Intelligence and the Brotherhood, individual members sometimes take great offence at the existence of the other, and Zayd is one such person. He opposes (or will oppose) you in virtually everything you do.
