Well the beast is what I was going to play if there is no Sister. Otherwise its unplayable.

The setting is the common Medieval Fantasy. There is a king and queen, castles and blah blah. Few people know of the Horde. So yeah go ahead and make up the backstory. The only things you may want to remember is the common religion around the Goddess. But you dont need to know too much on it.

And yes id actually prefer CS's be written here for now.
