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!

A goblin warband has found the secret tunnel which leads from the dwarven keep of Hearth-Home to the nearby hills. The tunnel is intended to be a means of escape if the keep ever falls to attackers, but now it has provided goblins with an easy way into the Underkeep. So far, the goblins have confined their attentions to the various underground rooms that make up the Underkeep, but sooner or later they will find a way to the surface. They pose a serious threat to Hearth-Home - the goblins must be cleared out of the Underkeep so this breach in security can be repaired before the orcs hear of it and overrun the dwarven keep. This adventure is slightly more challenging than Red Hand Trail, and it is recommended that it is played after that quest and before Palace of Dread. However, the scenario in Trouble Below can easily be played independently from the rest. Part of TSR 1076 The Goblin's Lair

Gray Mountain lies deep in the lush elven forest. The temple there was a haven of meditation and learning - until taken over by an evil cleric known as the Rahib. Far under the mountain, he paces before the temple's great altar. A brown-robed servant rushes in and falls to his knees, trembling at the sight of the Rahib's black panther. "Rahib, adventurers came to the village as the sun rose - the strangers now protect Rahasia." A scowl crosses the Rahib's face. "I must have Rahasia! Attack again tonight." As the servant scurries away, a deep growl rises from the giant cat. Gripping the panther's leash, the Rahib paces again, speaking out loud. "We must dispose of these strangers quickly; the secret beneath the temple will not wait much longer." Note: the setting is unspecified, but certain tie-ins, like the wines, prefigure Ravenloft.

The abandoned Tower of Ulvarum Orvernus stands atop an asteroid nearly a quarter mile in diameter, located roughly 5 million miles from the planet’s surface. The asteroid maintains Earth-like gravity and a breathable atmosphere, with habitable temperatures. This is all sustained through the harnessed power of a bound Air Elemental and Earth Elemental. If either of these Elementals are freed, the asteroid’s environment will quickly become inhospitable. The PCs may find themselves drawn to the asteroid through a forgotten portal, seeking a way to return home. Alternatively, they might be lured there by rumors of a powerful item or hidden knowledge within the tower’s extensive libraries. A multi-level tower filled with traps and strange encounters including animated armor, alien plant life, giant spiders, and a doppelganger.

But unnaturally powerful storms rock the tiny settlement just as the local lizardfolk tribe declares war on the colonists within. Are these threats somehow related? What became of the heretical cult of Gozreh that journeyed to the region a century ago, and do its corrupt teachings hold the key to calming the growing hurricane?

This deluxe adventure takes heroes into the ruins of Gardmore Abbey, a monastery that was once the base of a militant order of paladins devoted to Bahamut. According to legend, the paladins brought a dark artifact back from a far crusade and stored it in their abbey for safekeeping, and evil forces gathered to assault the abbey and take it back. What the legends don’t tell is that this artifact was actually the Deck of Many Things, a force of pure Chaos. This adventure brings characters into the extensive dungeons beneath the ruins - dungeons that are warped and twisted with the raw forces of Chaos surrounding the cards of the deck.

People in the Blight begin to awaken at night burning with an all-too-real fire. Most of them die horribly, spouses or lovers staring in shocked horror at their sudden death throes in the grip of consuming flames. A few of the truly unlucky actually manage to survive -- if living in such a state can be called survival. There seems to be no rhyme or reason in the victims of these incinerating dreams, as those among the high and low fall victim to its touch, and the locals each pray that he or she will not be next. Now no one dares to sleep. By renowned author and creator of the Blight, Richard Pett, The Crucible is a 7th-level stand-alone adventure of urban horror set in his own crooked city of the Blight. This adventure may not be suitable for children below the age of 13.

Along the caravan routes that tie the Cities of the West to the Kingdoms of the East, many tales are told of the mountains called the Towers of the Sun. One of these legends concerns a dark road said to be hidden among the twisty trails that spiderweb the mountains. Into the earth the road leads, into and through a series of vast caverns filled with treacherous traps and cunning monsters. Yet dangerous though the path is, many a party of adventurers have been tempted to walk it, for the stories say that the loot of a hundred lost caravans lies concealed along that evil way. [Comment: Uncertain for what levels of play this adventure is designed]

Special Basic/Expert Transition Module Barely one day's march from Kelven, the uncharted tracts of the Dymrak forest conceal horrors enough to freeze the blood of civilized folk.

The Dungeon of Graves, is nothing more and nothing less than a good, old–fashioned, First Edition dungeon crawl updated for the 5th Edition Roleplaying Game. Very difficult, it should strike fear into the hearts of the most stalwart adventurers. It offers an abundance of traps, tricks, and monsters. We hope that you find this module as fun and exciting as those thousands of players who have ventured into (and not as often out of) the endless caverns and mazes of Rappan Athuk—The Dungeon of Graves. Rappan Athuk is a difficult dungeon. Even the upper dungeon levels should not be attempted by a party of less than six mid-level characters.

Fear of the markings have forced the SALT Consortium to turn again to hiring adventurers to face what horrors await them in the Broken Halls of Goldahroud.

It's strange that a shrine to a vanished god should still be taking sacrifices. Not everyone forgets a forgotten god. The party explores an old shrine to a demon lord, kept up by a superstitious local.

When a priceless relic goes missing from the archives of an ancient monastery, only one party of stalwart adventurers has the determination and strength of character to go forth and recover it from a dangerous underground fortress. That party is yours.

Riddled with veins of precious ore and gem, the Earthspur Mountains to the west have long been a valuable resource for anyone able to mine them. One such mine has gone silent and the only thing more concerning than its long overdue shipment is the fate of the members of the Soldiery sent to discover what has happened to the mine’s workers. Though the mine lay in a region of the Mountains once claimed by a clan of reclusive dwarves, the Ludwakazar clan wouldn’t be so bold as to violate their long-standing peace with Mulmaster. Or would they?
