a vampire magic-user. This design enables him to combine his own powers with the surrounding environment, making him a difficult opponent to defeat. To celebrate the 25th anniversary of the Dungeons & Dragons game in 1999, two additional versions of the Ravenloft module were released. The first was a reprinting of the original adventure made available in the Dungeons & Dragons Silver Anniversary Collector's Edition boxed set, with slight modifications to make it distinguishable from the original (for collecting purposes). The second was the silver anniversary edition of Ravenloft that was adapted for use with the second edition Advanced Dungeons & Dragons (Wizards of the Coast periodically alters the rules of Dungeons & Dragons and releases a new version). Ravenloft II: The House on Gryphon HillRavenloft's success led to a sequel in 1986 titled Ravenloft II: The House on Gryphon Hill. Although Tracy Hickman was credited in Ravenloft II, he had left TSR before the module was completed. The writing was done by David "Zeb" Cook, Jeff Grubb, Harold Johnson, and Douglas Niles, following the Hickmans' outline. Each writer pursued a different section of the module in order to meet the deadline. Clyde Caldwell, who had done all of the art for the original Ravenloft module, provided the cover, but interior art was done by Jeff Easley. The adventure is designed for first edition Advanced Dungeons & Dragons characters of levels 8–10. The adventure was 48 pages, and included a large color map and an outer folder. It shared structural elements with the original, including variable NPC goals and variable locations for key objects, so that Gryphon Hill plays differently each time. The module's plot features an artifact known as The Apparatus that switches a monster's personality with that of an ordinary townsperson; player characters, therefore, are uncertain about the true identity of the people they meet. The module also introduces Azalin the lich, who later became a major character in the Ravenloft campaign setting. This module is playable alone, or as a sequel to the original Ravenloft. The module describes the town of Mordentshire, as well as some haunted moors, and a manor house, all of which are mapped in perspective like the original module. Adaptations In 1986, Ravenloft was adapted into the gamebook Master of Ravenloft, #6 in the Advanced Dungeons & Dragons Adventure Gamebooks series. In the book, the reader plays the role of Jeren Sureblade, a
