From the introduction: In 1983, TSR published the module named Ravenloft with the module code I6. It was written by Tracy and Laura Hickman and illustrated by Clyde Caldwell. This 32-page booklet had two outer folders containing maps by David Sutherland III. It spawned a 1986 sequel, I10 Ravenloft II: The House on Gryphon Hill; together, they formed the basis of AD&D 2nd Edition's Ravenloft campaign setting. In 2004, for the 30th anniversary of the Dungeons & Dragons game, Dungeon magazine ranked this module the 2nd greatest adventure of all time.
