Queen of the Spiders
Gary Gygax
 A new beginning was added to the adventure. Giants have been raiding civilized lands in increasing numbers, and the player characters have been asked to deal with them and also investigate the reasons or forces behind them. The first module (Steading of the Hill GIant Chief) takes place in a gigantic wooden fort populated by hill giants and ogres. Here the players also uncover evidence of an alliance with other types of giants, as well as some mysterious letters from those behind the scenes. The action moves to north to colder lands in the second module (Glacial Rift of the Frost Giant Jarl), the setting a system of caves clustered around a deep and narrow chasm in glacial ice. Here, the protagonists encounter frost giants, yeti and winter wolves among other monsters. The third chapter (Hall of the Fire Giant King) takes place in a volcanic region where King Snurre has assembled a horde of fire giants, trolls and hell hounds. A secret passage from this module leads deep into the earth, where the adventurers discover the true nature of the forces behind the raids - the drow in the service of Lolth the demoness. The next module, Descent into the Depths of the Earth, was on a larger scale than the others, and comprised a map covering many kilometres of a deep underground region, later known as the Underdark, with many unique monsters hitherto unknown to surface adventurers, including the drow, which had been considered legendary. Troglodytes, and new monsters jermlaine and svirfneblin (deep gnomes) made their first appearance in D&D literature. This is followed by Shrine of the Kuo-Toa, a subterranean complex populated by the Kuo-toa, a race of fish-frog monsters in the service of the lobster goddess Blibdoolpoolp. Finally, players make their way to the Vault of the Drow, a deep subterranean eldritch land in a huge cyst deep under the earth. The adventure is completed with Queen of the Demonweb Pits.
