No Unicorns...sorry guys
No Magic Eaters
The only Weres native to Ravencrest are the ones in the stories
No story concepts that start with the line: "I wanted to make it just like Story X but...."
No outlandishly crazy Weres like Shrimp or Jellyfish.
No introducing Unseen for the sole purpose of canon fodder for your protagonist.
No complaining about being told "No"
No Extinct Species (Will Be Explained Later)
