The Underdark is a subterranean wonderland, a vast and twisted labyrinth where fear reigns. It is the home of horrific monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a foul spell meant to ignite a magical energy that suffuses the Underdark and tears open portals to the demonic Abyss. What steps through surprises even him, and from that moment on, the insanity that pervades the Underdark escalates and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you! Note for DMs: This adventure is not for the faint of hearted, to run or to play. The module starts with 10 NPCs traveling with the party through the grueling Underdark. This number can grow. The encounters within the book are often incredibly deadly for the characters that would be going through it. This is because the module expects them to run or talk their way through the events, or, in some cases, the module expects them to lose. If your players aren't the kind of party to run, talk, or surrender, do not get this adventure. The module almost requires that you use milestone leveling because the experience provided does not commonly get players to the levels they should be once they get to certain milestones in the story (7th when they leave the underdark, 15th when they face the demon lords.) Good luck and happy questing.

"The creatures are just too intelligent, too crafty, and too strategy-minded to "rampage." Rampaging brings the wrath of oath-bound knights, powerful mages, and divinely-protected priests. Why would a dragon want such attention, unless it had some special secret, or unless it was insane? Or both. The northern reaches of the Derideth Swamp were once plagued by a rampaging dragon. This black dragon, named Storamere, took a mad glee in attacking human villages, wiping out orc camps, driving off the lizardfolk, and decimating farmland. He met his untimely end, though, in an ambush devised by the monks of the Order of St. Chausle. Storamere died with a curse upon his draconic tongue: "you could not have defeated me in my lair," he told his slayers. "I am forever invincible in my lair." Now Storamere is back, with a horde of his misshapen half-dragon offspring, to have his vengeance. All that remains of the once-heroic monks are two old men driven mad by their last encounter with the black dragon, so it falls to a band of adventurers to again defeat the mighty dragon -- this time in his palace, where the boastful Storamere claims he is at his strongest." Includes maps and damage rules for navigating Storamere's lair, a semi-solid palace made of a dangerous, corrosive liquid five feet thick and located on the ethereal plane. Most of the monsters in the lair have the Half-Dragon template applied. Published by Atlas Games
