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 party has been tasked with bringing the head of the fire giant king Snurre Ironbelly to the storm giant lord Krombaalt, as well as capturing the dwarven traitor Obmi Ironwhisper.

The adventure is part of the "Against the Giants" series originally by Gary Gygax, hence the writing credit.

In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room. At the bottom of this crumbling shaft is a labyrinthine dungeon shunned by all but the most daring adventurers. Known as Undermountain, this dungeon is the domain of the mad wizard Halaster Blackcloak. Long has the Mad Mage dwelt in these forlorn depths, seeding his lair with monsters, traps, and mysteries—to what end is a constant source of speculation and concern. This adventure picks up where Waterdeep: Dragon Heist leaves off, taking characters of 5th level or higher all the way to 20th level should they explore the entirety of Halaster’s home. Twenty-three levels of Undermountain are detailed herein, along with the subterranean refuge of Skullport. Treasures and secrets abound, but tread with care!

THE NEXT MARCH WASN'T DUE FOR ANOTHER 189 YEARS. TRY TELLING THAT TO THE MODRONS! On a regular schedule, the Great Modron March spills out of Mechanus, and the lawful automatons files their way around the Great Ring. No one knows why they do it, but everyone stays out of their way - because when the modrons march, they'll walk right over a berk who doesn't know enough to move aside. But this March has started decades before it was supposed to begin, and that's even more of a mystery. Caught unprepared, the planes shudder under the modrons' collective footsteps - and even the modrons themselves seem a little out of sorts. The Great Modron March anthology features 11 adventures for characters ranging from 1st to 10th level, as well as new information about the modrons of Mechanus. Each adventure can be played separely or linked together to form an extended campaign. The modron procession touches every Outer Plane in turn - and it isn't always welcome. On their unswerving path, the clockwork creatures will destroy celestial towns, be attacked by evil knights intent on using modron parts in foul experiments, and lead characters onto the deadly plains of the Abyss and into the famous prime-material labyrinth of Undermountain. Without help, they'll be lost in the swirling chaos of Limbo or even fail to complete the March entirely. And along their route, every blood on the planes seeks the answer to the most important question: Why have the Modrons abandoned their normal, lawful schedule to march years before they're due?

This adventure focuses on a Zhentarim attempt to spread terror in Mistledale, although it is suitable for almost any lightly settled area northwest of the Sea of Fallen Stars. "The Raiders of Galath's Roost" is suitable for four 1st-level characters, but PCs should be at least 2nd level before tackling the adventure's second half, the Zhentarim Citadel. Even in the first half of the adventure, many of the encounters are quite formidable for 1st-level characters, and the PCs might find it necessary to withdraw and recover one or more times before completely exploring the ruins.

"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

The waters of a sunless sea meet a pebble-strewn shore, beyond which opens a wide Underdark vista shimmering with pale cave-light. Titanic columns as big as castles march miles into the misted distance. The wide, steeply sloping base of the nearest colossal column is carved with streets, walls, and elaborate structures, many with gaping, empty windows. A few glimmer with faint illumination. Are you brave enough to explore the spire-city and face the terrors that lurk within? Part 2 of the Barrow of the Forgotten King series. Followed by Fortress of the Yuan-ti.
