Creator Ryan Murphy is keeping the details of the third chapter of American Horror Story, AHS: Coven, pretty close to the vest, as expected. We've known for some time that Season 3 would center on witches and feature a location where, as he said, "real horror had taken place." It was then revealed that at least three of the characters would be based on actual women who had become legendary either in, or following, their time. Bates and Lange were set to portray mortal enemies who had once been best friends. Oh, and we knew that production would take place in New Orleans.
