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 duergar mining expedition has led to a curious find - the entrance to the mythical Forge of Creation, where the first dwarves supposedly created the tools that brought civilization to the world. Their discovery has not gone unnoticed though, as their toiling within the forge has activated a portal to the Elemental Plane of Fire, drawing the attention of the efreeti Camus, Eyes of Midnight. The PCs are caught in a clash between the efreeti sultan and the meddlesome duergar, and must survive threats from each faction and the dangers that lurk within the forge itself!

A political wedding is threatening a major source of income for the Thieves Guild Ebonclad. Ebonclad would like to see the affair disrupted and the couple never wed. Such a job may be risky, and its outcome could very well start a war if done poorly or without subtlety. That’s why a team of promising agents has been assigned to handle it. The mission’s goal is to disrupt the upcoming wedding of Camilla Swain and Le’Nal Beshiin, to ensure Ebonclad keeps a revenue stream open that their marriage would surely close. The caveat is, neither the bride nor the groom are to be harmed. This will mean the party will have to come up with a method to disrupt the wedding as it’s happening, while avoiding suspicion. As a bonus, the party members can rob wealthy guests or steal wedding presents. The mission is open-ended, giving the players full reign to decide how they will work towards a successful outcome. It lets you work to guide player decisions based on the information presented here, or improvise results based on the players’ actions.

The adventures in Dalentown continue in The Darkness Beneath Dalentown. Workers in the town’s sewers have stumbled upon the long abandoned halls of the dwarves that once settled beneath this region. What they’ve found is a haunted library. What they’ve woken is something far more sinister! The Darkness Beneath Dalentown features hordes of oozes, undead, and demons festering for years in an ancient dwarven mining stronghold. Now, they are slowly working their way to the surface, and the folk of Dalentown are in dire peril!

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.

Beginning in the prison of the Castellan of Whitecliff, this campaign arc takes the players from level one to four, presented as a sandbox area in a lonely and gritty peninsula full of villains and opportunities for the players to explore.

Peculiar and hostile creatures of shadow lurk in the caverns and caves below. Political squabbling grows among the city’s powerful dwarf clans. All this makes the city particularly vulnerable to an enemy nobody saw coming - that nobody even imagined.

In this adventure the player characters start by investigating the strange behavior of the city's clergy.

After trailing this conspiracy to its source they discover a portal that leads to an ancient temple in the mountains. Using the portal, the PCs go to the abandoned ancient temple where they must confront both a cadre of fey and a band of mercenaries, from whom they learn there is a plot for a full-scale invasion of the region!

Anandak, a red dragon, has taken over an abandoned dwarven stronghold as his lair. He has also assembled together a rough confederation of monsters to act as his bodyguard. Anandak is preparing to enter into an alliance with the Black Prince, the March Lord Draven. The plan is for Anandak's monster allies to terrorize the lands north and east of Knacker Knob while the Black Prince, on pretext of marching to the aid of Knacker Knob, take control of Knacker Knob and the surrounding region. An emissary from the Black Prince, Lord Gonzaga, is currently in the dungeon, and he is in possession of papers that might reveal the Black Prince's treasonous plot. The lair is horribly overcrowded because monsters of all tribes and gangs are gathered to take counsel with the red dragon. Monsters are sleeping in the hallways because there is so little room, and the antagonism between races is at flash point. The PCs may be able to fan these resentments into intermonster battles. League of the Red Serpent is the third dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

From The Magazine: "Every summer, Duke Hightower holds a competition quite different from the traditional jousting and archery tournaments held by similar lords of his station. The rules of his tournament change from year to year, and, to oversee the games, the duke has appointed two wizard brothers who help choose the setting and create the rules and challenges of the competition. This year the competition is called the “Owlbear Run,” an overland race that requires each participating team to escort a live owlbear from the town of Telvorn to the town of Milvorn. The teams will face a variety of challenges; some are devised by the wizards, others by the competing teams or their sponsors, and some occur entirely at random. All of these tests are in addition to the challenges inherent in motivating a temperamental owlbear. Fortune and fame await the first team to cross the finish line, and the local lords sponsoring the race are eager to enlist skilled champions for their causes." Pgs. 2-27
