The post led me to think about crime in the magical world. What kind of scams could happen in your magical setting? What would count as magical power abuses? My fairy godmother Eileen often protested at magical power abuses (defined by her as using too much magical strength that the occasion warranted, she has always hated any form of bullying).
The obvious misuse of magic would be to use it to try to enslave the world in your stories (e.g. Sauron from Lord of the Rings and Voldemort from Harry Potter) but what about more subtle misuses? Could magic be used in such a way people are not aware they are being controlled? Who would detect this and stop it?
Who carries out the scams you've set up? What do they hope to gain? How are the scams stopped and who are the law enforcement agencies in your world? Ironically my last post for Chandler's Ford Today was called Watching the Detectives so I have written on both sides of the legal fence in the last two weeks!
