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.

In the ruins of Kiris Dahn, a human town, lies a 'Slaying Stone'. The stone is said to have the power to kill any foe, though the stone is consumed in the process. The party will venture into the ruins which are the home to an assortment of goblins, hobgoblins, and kobolds. However, a mercenary band of orcs have been hired (by a benefactor who is not met in the module) to search the ruins for the Stone, and the party must find it first. The party must use caution and stealth to move through the town without alerting the denizens or the mercenaries while searching strategic points around the abandoned town to find the Stone. Eventually, the party should find the stone under the protection of an indifferent Brass Dragon.

A sickness has come unto the simple mining community of Duvik’s Pass, poisoning their wells and blighting their crops. With the pestilence leaving the strongest men of the town’s guard a few short days away from death, the burden of descending into the mines and purging the wellspring of whatever evil has settled there falls to an intrepid band of adventurers.
