I'd started an AU of people called "pushers" who could, well, push others into obedience with their wills. Built a whole culture around it. It was going to be the subject of a sidekickfic challenge, in fact, but there didn't seem to be a lot of enthusiasm. And then the cult AUs started and DUDE, DUDE, DUDE, more people need to write these things! YOU SHOULD TRY!
