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!

"Something Fishy" - a Celtic-world campaign. "Iasc" is set in a small Celtic kingdom that can be fit into any medieval/fantasy campaign. The PCs need not be Celts. The likelihood of combat is very high, and the party is recommended to host several warriors.

As a member of a bold party of adventurers, you and your associates have trekked far into what seems to be a whole underworld of subterranean tunnels -- arteries connecting endless caves and caverns which honeycomb the foundations of the lands beneath the sun. Your expedition has dogged the heels of the Dark Elves who caused great woe and then fled underground. This module can be played alone, as the conclusion to module D1 & D2: "Descent into the Depths of the Earth," or as the third module in a series that forms a special extended adventure (G1-G3: "Against the Giants"; D1-D2: "Descent into the Depths"; and Q1: "Queen of the Demonweb Pits").

As adventurers, you may think you have seen everything: certainly your skills have brought you through unimaginable dangers. But now you suddenly find yourself in a place unlike any through which you have traveled: astounding, dangerous, and even amusing things confront you as you journey, both indoors and outdoors, through unique and wondrous realm of Dungeonland. This adventure was first conceived by E. Gary Gygax as part of the Greyhawk Castle dungeon complex and has been the source of challenge and fun for many skilled players of the Advanced Dungeons & Dragons game. It is finally available to all players and can be added to your existing campaign with ease. "Dungeonland" is also designed so that it may be used along with its companion scenario, EX2: "The Land Beyond the Magic Mirror." Still, "Dungeonland" may easily be played on its own, and should offer hours of excitement in its strange landscape! TSR #9072

"For Blibdoolpoolp!!" "The power of the mind and belief are wonderous, often leading us to manifest things that aren’t real. For the kuo-toa, this power is heightened, allowing their collective belief to manifest gods." Two tendays ago, a paladin of Torm was kidnapped by kuo-toa. In a strange turn of events, she was mistaken for a kuo-toa god, and whisked off to their underground lair. Barria has managed to pose as the god and now shakily leads a small faction of kuo-toa while trapped underground. With her influence being increasingly scrutinized, and with the different kuo-toa sects on the brink of civil war, it’s a dangerous time, even for a ‘god’… The heroes’ mission — rescue the paladin from the kuo-toa oceanic lair before she’s transformed into a kuo-toa god. The kuo-toa are an Underdark-dwelling race of fishlike humanoids. Different sects worship different god-like beings, each god manifested through the strength of a sect’s collective zeal. Such “gods” feature prominently in this adventure. Product Overview ♦ 4 to 8 hours for four to five characters. ♦ Scalable for 3rd-6th level. ♦ High-resolution maps of the Kuo-Toa lair. ♦ 9 new statblocks, including Dire Barnacles and Hypno-Cuddlefish! ♦ Includes plot hooks, handouts, rules for faction combat, and more!

The Godless Depths For the first time in eons, ancient aberrations are emerging from the deep ocean. Driven by some otherworldly fervour, they encroach upon the local villages, searching with beady eyes for anyone linked to the Gods. Even now you hear rumours of kidnap, men and women dragged kicking and screaming into the depths.

The characters will investigate a grim mystery in the elven village of Alkai Tor, hunt for answers in a lethal swamp, and finally confront a desperate killer in the Temple of Shattered Minds itself.

Chapter 1 - When a relative of someone close to the characters goes missing from a nearby village, the players are asked to investigate. The party has to recover stolen goods from a thief before setting out from the City of Ravens Bluff. They travel through the wilds of Vesperin in search of the missing person, finding trouble and helping locals along the way. Chapter 2 - As the journey continues, the party arrives in a small hamlet suffering from a strange blight. The players will need to investigate the situation and choose sides in a longstanding feud between the mayor and a local magic user. Chapter 3 - After clearing a tribe of violent orcs from a nearby mountain pass to protect the residents of a town, the party will have to enter the lair of a long-dead dragon to rescue their quarry from a band of goblinoid slavers, where they discover an entrance into a dwarven city, lost and forgotten centuries ago. Chapter 4 - The party will have to traverse the ruins of the dwarven city, avoiding hazards and battling the horrors that lurk there, to uncover the identity of the slaver's leader. A discovery that will lead them through a treacherous forest to the city of Tsurlagol in search of a pirate ship called the Star Carver, and its drow captain, The Viper's Kiss. Along the way, they meet an unlikely ally. Chapter 5 - Once they arrive in Tsurlagol, the players will have to choose between gaining the assistance of the city council to fight the pirates head on, or making a deal with the Viper's Kiss, herself. The path they choose will either lead to an epic battle on the Sea of Fallen Stars, or into the deadly sewers and tunnels beneath the city to face an enclave of wererats, undead, and a tribe of mad, kraken-worshipping kuo-toa, in search of a fabled relic.

But once the heroes join the raiders, things aren’t as clear as they were led to believe. Will they succeed at their mission? Or join the raiders themselves? Pgs. 54-82

Having put down a rising of giants, it was discovered that the motivating force behind their depredations was that of long-forgotten evil - the Dark Elves. Determined to seek out these creatures, a body of doughty adventurers mounted an expedition to learn the strength of the Drow and bring retribution to them (DUNGEON MODULE D1, DESCENT INTO THE DEPTHS OF THE EARTH). This module contains background information, a large-scale referee's map with a matching partial map for players, referee's notes, special exploration and encounter pieces, a large map detailing a temple complex area, encounter and map matrix keys, and an additional section pertaining to a pair of unique new creatures for use with this module and the game as a whole. A complete setting for play of ADVANCED DUNGEONS & DRAGONS is contained herein. This module can be played alone, as the second part of a series of three modules (with DESCENT INTO THE DEPTHS OF THE EARTH, D1, and VAULT OF THE DROW, D3), or as the fourth part of a continuing scenario (DUNGEON MODULES G1, G2, G3, D1, D2, D3, and Q1, QUEEN OF THE DEMONWEB PITS).

No-one knows why, but many of the villagers of Greenmist have been going insane. Not only that, but something has caused the surrounding environment to transform into fetid swamps. Heroes from far and wide have gone into the swamps to destroy the source of the madness, but none have returned. The truth is that the psychic whispers of an aboleth have invaded the minds of Greenmist's people. The creature called Seedooloo has been using forbidden magic, mad science, and the strange ability of his kuo-toan worshipers to grant himself the power to drive the surface world to insanity. The Call of Seedooloo includes monsters found in Mordenkainen's Tome of Foes.

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.

Agents of the fire giants of Maerimydra, a city in the Underdark, have overtaken the drow outpost of Szith Morcane. The factions seek out adventurers to free the outpost’s leaders for questioning on the giants’ activities. Can you extricate them before it’s too late?
