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 Licktoads, once the great and fierce goblin tribe in Brinestump Marsh, were defeated by human adventurers! All that remains of the tribe are its four goblin "heroes". Homeless and bored, they left their swampy homeland to join the neighboring goblin tribe, the Birdcrunchers. The good news is that the Birdcrunchers are willing to let the goblin heroes join their tribe. The better news is that the Birdcrunchers have heard of these four, and want one of them to become their new chieftain. The bad news is that before the goblins can join, they'll need to endure a series of dangerous and humiliating tests. Very dangerous. Very humiliating. The worse news is that lately Birdcruncher chieftains have had really short lifespans—they're being killed by the pet fire-breathing boar of a local ogre who wants the Birdcruncher land as his own.

Explore an abandoned wizard’s tower in this short mini dungeon! This adventure is a Micro Dungeon. Preface Long ago a wise wizard named Adubeus lived deep within the forest. As he lived, he would pass out nuggets of wisdom to those in need, and aid the local townsfolk in times most dire. Long past are these happy days, however, and the kindly old wizard has not been seen in many decades. Some say he found a calling elsewhere in the world, while others whisper of his demise at the hands of a secret experiment gone awry. One thing is certain, however. His tower, long forgotten, still stands out there in the forest. Occasionally, some hapless person wanders upon it much to their personal peril. The specific details of Adubeus are left vague on purpose. This small adventure is intended to be played as part of a larger campaign, and the location can be modified to fit your setting. The reasons for your adventuring party to be heading towards the tower are entirely up to you, however, below are some good sample adventure hooks.

Caravan of Peril takes place on the unprotected roads and trails of the wilderness between cities. Merchants, pilgrims, and wanderers have long banded together in wagon caravans for safety when setting off into the wild -- yet a caravan is only as safe as its hired guards. There's plenty of coin to be had on the road for those with a swords (or spell book), a steady will, and a taste for adventure.

Whatever the case, payment is 25gp each, paid upon safe arrival in the next city.

It also includes new material for judges who want to send their adventurers in a Stone Age setting!

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.

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. Sometimes it kills, yet just as often it spares a victim, leaving clear signs of what it might have done had it wished. Its visits are now marked by strange and illegible symbols scrawled in blood on the walls of the buildings. The people are worried, helpless, and desperate. Desperate enough to welcome adventurers. UK2: "The Sentinel" (1983) is the second UK-series adventure, the fifth TSR UK adventure overall, the first solo effort by Morris, and the first half of the two-part Adlerweg series (whew!). It was run as a tournament at the GamesFair '83 Open, then published later in 1983. TSR 9101

The end of the road. A lonely fort stands on the banks of a mighty river. It is here the hardy bands of adventurers gather to plan their conquests of The Hill, the hulking mass that looms over this tiny settlement. The Hill is filled with monsters, they say, and an evil witch makes her home there. Still, no visitor to The Hill has ever returned to prove the rumors are true or false.

Sleepyhead. The only man who can stop the amphibian horde needs a wake-up call. The party must find a missing druid an bring his captures to justice. Pgs. 8-21

This adventure takes place in the Moonsea of Faerûn. The players have been brought to Melvaunt to search for the missing scions of the city's great families. To the north, in Thar the orc tribes converge on the ruined fortress of Xul-Jarak, flocking to the banner of a charismatic warlord. There, he intends to sacrifice the scions of the great families of Melvaunt in a bloodritual to Gruumsh. The players will escape Melvaunt, search along the wilderness of Thar for the Fortress of Xul-Jarak, and then explore the dungeons of the ruined fortress and hopefully rescue the scions before they are sacrificed. There also is a Web Enhancement by Eric Cagle on the archives of wizards of the coast's website designed to scale the adventure to level 8. For example, it replaces the Owlbear with a Tyrannosaurus. This is an easy to scale adventure with much of the player's difficulty coming from intelligently avoiding problems, choosing how to approach each floor in the most tactical way, and quickly adjusting when something goes wrong. The adventure has sidebars including common orc battle cries (In Orc!), ready to use orc names, weather and random encounter table in Thar, a description of what happens if the party fails or partially succeeds, and suggested minis for each of the encounters. There is even an extended description of the bloodspear ritual, an event the party is not meant to encounter in a normal run. The appendix is detailed for all the humanoid characters including the scions and their equipment, the named villains, and variety of unnamed orcs the party will encounter. The fortress also offers an opportunity to introduce the players to the Underdark and the Zhentil Keep. There is a passage to the Underdark the players can accidentally explore, and return to later. Emissaries from Zhentil Keep have come to watch the ritual and have their own motivations. These npcs provide an opportunity for exposition and role playing at a point which otherwise might be combat heavy, acting as a valve for the first floor - helping or hurting the party with subtle magic should the difficulty be off.

The Characters come across an ancient wizard's tower. The nearby keep has been reduced to rubble over the ages, but the tower is in perfect condition. It is surrounded by an impenetrable force field that cannot be breached - not even by the ghost of the long-dead wizard, who has been trapped within for centuries. Surely there must be great treasure within this magical abode. But how to get to it?
