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!

Part Two of the Umbral Aristocracy Trilogy. The treasure hunt has led to the City of the Dead. Beneath that well-manicured park is an ancient crypt where the treasure awaits you!

Remember the golden days of role-playing, when adventures were underground, NPCs were there to be killed, and the finale of every dungeon was the dragon on the 20th level? Well, those days are back. Dungeon Crawl Classics feature bloody combat, intriguing dungeons, and no NPCs who aren’t meant to be killed. Each adventure is 100% good, solid dungeon crawl, with the monsters you know, the traps you fear, and the secret doors you know must be there somewhere. In Idylls of the Rat King, goblin bandits are once again attacking the silver caravans, killing innocent miners and stealing cargo. The goblins have taken up residence in an abandoned mine northwest of Silverton. Someone must get rid of them. But this is no ordinary abandoned mine. It was deliberately barricaded generations ago when the Gannu family, founders of Silverton, discovered an unspeakable evil on its lowest levels. And these are no ordinary goblins, for the curse of the Gannu family courses through their veins…

The Fate of Faerûn Lies in Shadowy Darkness! Daggerdale is reeling from a sudden series of murderous drow raids. As a grave threat to the entire surface world develops in the war-torn dark elf city of Maerimydra, intrepid heroes must discover its source and destroy it, if they can.

In ancient times, the area now known as the Dyrgalas Fens was home to a flourishing civilization of nature worshippers who wrested a living from the forest around them, built open-air temples, and generally did well. Over the centuries, a series of natural disasters (some say a series of foolish magical experiments) led to a rising water table and turned the forest into a vast swamp. As the water rose, most of the people left. Today, a few stalwart humans remain in the fens, living off the land through hunting, fishing, trapping, and even some agriculture. In addition to these honest folk, the Dyrgalas has some less savory residents, including both black and green dragons, trolls, hags, escaped criminals, and a host of lycanthropes. Most of these creatures prey on travelers foolish or unlucky enough to enter the fen, and sometimes raid both inside and outside the fen. This adventure, intended for characters of levels 6 to 8, deals with one group of raiders who make their lair in the Dyrgalas. A weretiger called Gavriil has formed a group of assorted lycanthropes into a band of cunning brigands. The lycanthropes favorite caper involves infiltrating a merchant caravan while posing as travelers, merchants, or swords for hire, then attacking it from within. Gavriil and his servants also take on kidnappings, murder for hire, and any other unsavory tasks that come their way.

The characters arrive in Thaliost, a city rife with unresolved tensions from the Last War. Through danger and discovery, the party will discover that the Lammanian artifact they were sent to escort back to Sharn has been stolen. They’ll have to track down the thief, who jumps onto the Five Nations Express, House Orien’s flagship lightning rail service, in a bid to escape to the Eldeen Reaches and open a gate to apocalypse.

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

"The Devil Box" is a D&D adventure suitable for four 2nd-level PCs, although it can be modified for parties of 1st or 4th-5th levels as noted int the "Scaling the Adventure" sidebar. Characters completing the adventure are likely to advance to 3rd level. Much of the action takes place in a small town during a festival; this town can easily be dropped into an existing campaign. Since "The Devil Box" expects the PCs to deal with kobolds as temporary allies, it throws in some ethical dilemmas for good-aligned characters. Paladins and good-aligned clerics my have difficulties with such an alliance, but kobolds are definitely the lesser of the two evils involved in this adventure. If the party spurns the assistance of potential kobold allies, you may wish to modify the adventure to make it a bit easier on the player characters, as encounters have been written with the assumption that the heroes have a little help. Uploader's note: A hilariously creepy adventure involving a circus (freakshow), with in style illustrations! (Grid maps included, but not separate maps.)

Not even memories of past glory live on in the gentle hills around the village of Kusnir. Today its people have more concern for commonplace things, like the harvest, trade, and the threat of death in the night! Kusnir is beset by a skulk. The attentions of such a creature are a curse on any community. Streets and alleys which ring to the voices of children by day become fearful, shadowy places by night. Men go abroad armed and in groups, while women and children stay behind locked doors and even there are not safe. But life goes on. The lot of the peasant is always hard, what cannot be prevented must be endured and, of course, things could be worse. Much worse. The skulk has begun to visit the village more and more often.
