After Will vanished, the boys at the police station attempted to explain the bizarre events through the lens of <The Lord of the Rings> and <The Hobbit>. While Chief Hopper couldn't grasp it at the time, the boys were right all along. To them, this quiet little town was already a vast fantasy world. The password for Will's hideout, 'Castle Byers,' was 'Radagast'—the Brown Wizard—and the forest trails they raced through on their bikes were their very own 'Mirkwood.' They just didn't know their fantasy was about to become terrifyingly real.
