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 PCs intervene in an attempted murder and are hired to find out what made a guy go mad. This leads them to search for Yenejg Togan's tower/a strange merchant in the nearby forest, where they discover that bugbears have moved in. After exploring the tower, finding the "merchant", and dealing with the bugbears and the lamia that caused the incident in the first place, they were still unable to get into Yenejg's inner sanctum without a key. The PCs return with the key and figure out how to use it to enter Yenejg's sanctum. They then explore it, dealing mostly with traps, and finally discover the resting place of the treasure Yenejg stole from the town. This adventure begins with a skill-based roof-top chase and can include some complex non-combat interactions with potentially hostile NPCs. It includes some semi-interesting traps as well as some nifty puzzles. No villain to speak of. Fool-hardy adventurers can get themselves killed, but some caution will result in only one extremely hard fight, and even that can be avoided if action is taken quickly. Pgs. 74-107

But as the heroes find themselves the target of mysterious attacks, they begin to discover that something rotten lurks in the city’s heart. Sunlight bathes the soaring towers of the eladrin city of Mithrendain. Gentle breezes swirl through wooded parks and along well-kept streets, and in the ancient settlement whos golden hues have seen it named the Autumn City, thousands live in peace and prosperity. For centuries, the fomorian chasms deep beneath the city have stood silent below the great magical seals that closed them in the wanting days of the eladrin empire. Over long years, the folk of Mithrendain have forgotten the dark threats of old, becoming complacent in their tranquility. And so none suspect that corruption lurks at the heart of the city, spreading out from the shadows to taint all it touches. Pgs. 104-128
