Imagine this: you're a normal person in our everyday world, and you get a letter. It has a place and a time, with an invitation to witness something. Something fantastical. Something crazy.
The standard stuff, really. Be nice, don't auto-hit, don't god-mod, don't control other people's characters, character deaths should be with the user's permission, and so on. If you need an explanation of any of these, let me know.
Additionally, I'm going to be managing the game's environment to a large degree. If I am controlling the environment, let me control the environment.
While things will start getting crazy at a certain point (hence the name), characters should be pretty normal to start with. So no vampires, mmkay? Seriously, though. No vampires.
