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.

Sewers of the Underguild is an adventure designed for characters of at least 11th level, and characters up to 15th level will find plenty of challenges. Hidden within these narrow passages and filth-filled channels is a guild of vampiric rogues, led by their master Sangre and his aide, a nycaloth called Ankoz. Deadly traps abound, so a skillful rogue will be a lifesaver. Because of the high likelihood of desperate combat with numerous vampiric and monstrous opponents, it is suggested that a cleric and at least two fighters be prepared to beat back the many watchdog monsters the guild employs. You can hide the locales in Sewers of the Underguild in any ruin or location that fits your campaign purposes. A thriving metropolis that just happens to have a large crime and vampire problem would fit the bill nicely. In the Lost Lands campaign setting of Frog God Games, the Underguild is located in the sewers beneath the ruins of Curgantium, the ancient imperial capital of lost Hyperboria. Located at the edge of the modern Kingdom of Foere, the Underguild still finds itself located centrally enough to pull the strings of its weblike network running throughout the former lands of the Hyperborian Empire.
