Descent Into the Depths of the Earth (original)

This module (titled Descent INTO the Depths of the Earth on the cover) is the 1981 edition and contains the material previously published separately as D1: Descent into the Depths of the Earth and D2: Shrine of the Kuo-Toa. This carries the adventure on from the outcome of the Against the Giants series of modules as the players explore the role of the Drow in instigating the Giant alliances.
