Ravenloft is a Dungeons & Dragons module, coded I6, published by TSR for use with the First Edition Advanced Dungeons & Dragons. It was written by husband-wife duo Tracy and Laura Hickman, with art by Clyde Caldwell and maps by David Sutherland III. Ravenloft is considered by many to be one of the finest Dungeons and Dragons modules ever published. Ravenloft was also ranked the 2nd greatest Dungeons & Dragons adventure of all time on the 30th anniversary of the Dungeons & Dragons game. Ravenloft inspired a sequel, a gamebook adaptation and an entire campaign setting which in turn had many spin offs. The original Ravenloft adventure itself has been revised and republished several times.
