Ravenloft is a campaign setting for the Dungeons & Dragons roleplaying game. It is an alternate time-space existence known as a pocket dimension or demiplane, called the Demiplane of Dread, which consists of a collection of land pieces called "domains", brought together by a mysterious force known only as the Dark Powers. Each domain is tailored to and mystically ruled by a being called a Darklord who is forever trapped and surrounded by magical mists surrounding the domain. Strahd von Zarovich, a vampire in the original AD&D Ravenloft I6 module released in 1983, became the first Darklord, both ruler and prisoner of his own personal domain of Barovia
