Dead Gods, softback Planescape deluxe adventure for AD&D 2nd/2.5th edition, by Monte Cook
“Silently, ponderously, they float through the Astral Plane, mammoth isles of rock adrift in an endless sea of silver. Once they were gods. Now they’re little more than debris, petrified husks of fading belief and forgotten prayer. Yet for many, their memories linger, their dreams live on – and for some, those dreams are terrifying nightmares of vengeance, and conquest, and death.
Dead Gods is a 176-page adventure book featuring two scenarios that can be played separately or linked together. In the first, the heroes are drawn into an epic quest to uncover the secrets behind the return of an infamous AD&D villain long though dead. In the second, the city of Sigil threatens to explode in a faction war for control of an old church and a mysterious force lurking within it. Dead Gods also features a MONSTROUS COMPENDIUM entry for a brand-new fiend, full-color illustrations to bring scenes alive for players, and a poster sheet of maps for the Dungeon Master.”
Number 14 in Dungeon Magazine’s list of the 30 Greatest D&D Adventures of All Time and, because it was produced very late in TSR’s existence only received a short print run. So it’s very rare.
