A gothic horror setting originally created for an adventure module, Ravenloft, then expanded into an entire series and campaign setting. After years of production by TSR and WotC, Wizards licensed Ravenloft to Arthaus Games, which published its materials through White Wolf, Inc.'s Sword & Sorcery label, but rights returned to Wizards of the Coast in early 2006. In October 2006, Wizards released Expedition to Castle Ravenloft, an updated version of the original module, as a hardcover. In August 2010, Wizards released the Castle Ravenloft board game, and in 2011 announced the release of the Ravenloft Roleplaying Game, which was a standalone game that can double as a 4th Edition Campaign Setting. This was subsequently canceled.
