Lost Tomb of Martek (Advanced Dungeons & Dragons Adventure Module I5)

Last module in the Desert of Desolation series. The goal of the PCs is the tomb of the millennium-dead wizard Martek. The tomb lies in the vast Desert of Desolation, and the majority of the adventure takes place within Martek's tomb. The adventurers have to cross a sea of glass on skate-ships, and then pass through the Crystal Prism and the Mobius Tower in order to reach the final crypt. The adventure is organized into seven parts, taking the party from the desert through a number of planes on their way to the Citadel of Martek.
