A fanlisting is a place for all fans of a particular show, movie, actor/actress, singer, etc. to come together and build the biggest listing of people from all around the world who are fans of that subject. (from TheFanlistings.org)
This particular fanlisting is for fans of Unreal Estate, an original story by Stefan "Twoflower" Gagne, involving a cast of brilliant characters and a multiverse of many unique artificial Realities. If you're one of them, feel free to join!
