Ravenloft is a gothic horror campaign setting for the Dungeons & Dragons role-playing game. Originally designed by Tracy and Laura Hickman for TSR, it was licensed by Wizards of the Coast to Arthaus, who published a new edition compatible with the d20 3.5 edition rules, along with various supplements. Rights to Ravenloft reverted to Wizards on August 15, 2005, though Arthaus were allowed to continue selling their back stock until June 2006.
