Dark Tower is an adventure which describes a dungeon contested over by followers of Set and Mitra and the surrounding lands. The module describes a village and four challenging dungeon levels in detail.
Lawrence Schick, in his 1991 book Heroic Worlds, notes that this "Popular scenario" was "Judges Guild's best-selling scenario."
Dark Tower was ranked the 21st greatest Dungeons & Dragons adventure of all time by Dungeon magazine in 2004, on the 30th anniversary of the Dungeons & Dragons game. This is most noteworthy because Dark Tower was the only adventure module to make this list that was not produced by TSR, Inc., the direct antecedent of Wizards of the Coast.
