How different things seem now from when you undertook the crushing of a few rebellious hill giants! What seemed a simple adventure has turned into a major expedition. Much time has passed since you discovered the conspiracy that led you to the frost giants, fire giants, and eventually to the long-forgotten Drow. Through your encounter with the dark elves, you have found the true source of the evil -- the demon queen Lolth! This module is the exciting conclusion of a series of seven AD&D modules. It may be played on its own or as the climax of the "Giant" series (G1-G3) and the 'Drow' series (D1-D3). The first of a new series of other-planar adventures, this module includes several new monsters, maps of the Demonweb and lair of Lolth, and notes on eight alternate worlds, suitable for expansion and addition to existing AD&D campaigns.
