from the cover: TOMB OF HORRORS is a Dungeons & Dragons adventure for five characters of 11th level. It can take place in a marsh region in any game world. The original version of this adventure was first shown at the official Advanced Dungeons & Dragons tournament at Origins I in 1974. It was published as Dungeon Module S1 in 1981 using the 1st edition rules, the story was expanded in Return to the Tomb of Horrors in 2nd edition, and the rules were finally updated in 2005 for Dungeons and Dragons version 3.5. Thirty-four years later, the original module is being updated to the latest version of Dungeons and Dragons, 4th edition, where Acererak will hopefully find a new home to house his diabolical machinations. user note: This fan work was published one year before the official D&D 4 Tomb of Horrors.
