So you have a setting where non-human beings exist, and their nature makes living among humans difficult. Maybe they suffer from a Horror Hunger, live forever (and it sucks), have customs that don't endear them to locals (such as rampant kleptomania and throwing around Curses like it's going out of style) and/or the stress of keeping up the Masquerade is just brutal. Well, there's a support group of reformed/reforming monsters that is out to help those among them who want to live closer to humanity. Possibly even to regain some of that humanity if they were human once. They may even help convince a newly turned member he isn't human at all.
