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!

Far below the Fields of Petrichor is a vast cavern containing the skeletal remains of a long-dead Sonorous Titan, a whale-like beast that once floated through the skies of a lost age. Amongst the bones are ravines and grottos home to bizarre creatures and lost treasures that are as beautiful and valuable as they are deadly. Ghostly shapes swim through the air. Glowing mushroom groves hide frightened creatures. And the Titan’s bones sing sadly as an ambitious wizard and his weary hirelings dig for its precious marrow...

The spire has existed for as long as locals can remember. Rising above the sand near the ocean, the spire is topped by a natural cave system. Stories about the place circulate around the docks and taverns of the nearby towns—dark tales of ritual sacrifice and the worship of long dead gods of lightning and storm. Many claim the victims of the old cult still crawl through the tunnels accessible at the peak of the spire. Others say a new scaly threat now lairs there, and the storms of late have been most violent near that place. In this explorative and perilous adventure, the party ascends a great rocky spire to face the place’s past and the blue dragon that presently resides there.

Beneath the frozen waves, an ancient power stirs. In the icy north, ships vanish without a trace, drawn toward a massive drifting iceberg. Legends speak of a powerful artifact buried within—one that calls to the sea and those who sail upon it. But the glacier is no ordinary formation; its tunnels are filled with lurking predators, yeti clans, and an ancient Icebound Hydra whose severed heads regrow as living ice.

Deep in these caverns overrun with all sorts of foul creatures are two sister hags. Once of the same coven, they now have a bitter rivalry but both refuse to the leave these caverns they call home. The cave received its name thanks to the terrifying sounds that echo through it. Some say it is just the wind brushing against the stone but the rumors all speak of two horrifying sisters casting curses and performing diabolic rituals with human sacrifices in a never-ending hatred. Heroes will face goblin, hag, bat, hook horror, and other terrifying monstrosities deep within the tunnels of The Shrieking Caverns. This dungeon does not contain any of the puzzles from the puzzle section, though there are a few situations the players will find themselves in that will require more than phsyical strength. That being said, this dungeon contains many combat encounters and is expected to take multiple nights to complete.

The Baronies of Erlkazar, once a prosperous region of pastoral tranquility, is now a land of nightmares and dread. Bandit armies plague the region, terrorizing the populace and surrounding countries of Calimshan, Tethyr, Amn, and Turmish. Though these threats are terrifying enough, it is nothing compared to what awaits the people of Erlkazar at night. In caves, tombs, and subterranean communities beneath the seemingly pastoral villages of Erlkazar live the secretive Night Barony. Ruled by the vampire Saestra and her legions of darkness, these monstrous denizens of the Five Baronies are the real power in the region. The country’s only hope of liberation is you.

Bandits have been preying on the caravan trade of late, and the number of burglaries and kidnappings is on the rise. Such events might not seem all that unusual, except for the bandits' calling card -- webbing! Can the PCs penetrate the bandit lair and slay the leader before any more locals vanish?

Stories of misfortune are often exaggerated, especially when they have been retold many times. For that reason, most people aren't taking seriously the claim that a sea monster living along the coast is eating whole ships full of sailors and swallowing entire families. But there's no denying a few facts -- the town of Lochfell is losing its citizens to a sea monster (one that walks on water no less), someone is stealing that same town's dead, and ships are beginning to choose other ports for unloading their goods. Such a scenario could doom the residents of the small port town to either a monster's gullet or the poorhouse. No one seems to know whether the town's two ongoing problems are connected, but the sea monster never leaves behind a corpse to bury. Is it collecting bodies for some dark purpose? Or did some more powerful evil creature create the sea monster to do its dirty work? Someone in Lochfell knows the answer, and it's up to the PCs to find it out. Lochfell’s Secret is a short D&D adventure for four 15th level player characters (PCs). The story is set in and around the port town of Lochfell. You can place the action in any section of your campaign world where a coastal town on a bay might exist. If there is a small town that the PCs visited in a past adventure but haven’t returned to in quite a while, so much the better. As always, feel free to adapt the material presented here as you see fit to make it work with your campaign.

Within the muck and darkness of a cave off in the forest lies an ancient creature. A manifestation of evil and psychosis that causes even devils and demons to turn a blind eye. This monstrosity is known as The Gol'Goroth. Rumors say it has just sockets where there should be eyes, yet it sees everything in this world and in others. It pierces the veil of the mind and inflicts madness on all who come near . . . of course these are surely just rumors. Surely just an excuse to justify the actions of a twisted cult that is ravaging local villages. Surely this is just the manifestation of their crazed minds as they carve their own bones into weapon and slice their own flesh to ribbons - all in the name of the Gol'Goroth

From time out of mind, the standing stones known as the Circle of Cahervaniel have stood lonely vigil on a grassy hilltop. Sheepherders once moved their flocks over the hill and through the circle, sometimes resting in the cool shadows cast by the ancient stones. Everything changed when a stone finger fell, revealing a fissure in the earth. Now, dark shadows caress the circle after the sun sets. Creatures out of nightmare dance upon the hillside at night. Many swear that a unicorn of deepest ebony now hunts all upon two legs who draw near, while stunted creatures scurry in the shadows, abducting sheep from their sheds and drawing them down below ground for food. After the disappearance of a sheperd, fear grows stronger in neighboring villages. Who will brave the black hollow of the ancient Circle of Cahervaniel? Heroes of stern mettle must descend into the cavity and explore the ancient spaces existing there. Product History "The Shattered Circle" (1999), by Bruce R. Cordell, is a generic adventure for AD&D 2e. It was published in January 1999. Origins: Another Generic. After Wizards of the Coast began publishing D&D, their first year and a half of generic adventures were all classic revivals: returns to RPGA tournaments, to classic adventures, and to Dungeon scenarios. Even "A Paladin in Hell" (1998) was a return in its own way, to the demons and devils that TSR had become afraid of. Wizards was staking out new ground by reclaiming the past. "The Shattered Circle" (1999) was the first generic Wizards adventure that was simply a generic adventure, with no deeper origins and no hidden motives. Artifacts of Note. the foundingstone and the harp Euphonious are both one-off named magic items. However, it's sword Icerazor that's the most interesting. It's said to have grown from a shard of Frostrazor — a sword that would only appear ten months later in Return to White Plume Mountain (1999). There, it's listed as one of Keraptis' four implements of power, alongside Wave, Blackrazor, and Whelm — meaning that Icerazor (and this adventure) are just one step removed from White Plume Mountain itself. Monsters of Note: Chitine. It's somewhat curious, given the Greyhawk and Neverness connections, to note that the chitine debuted in MC11: "Monstrous Compendium Forgotten Realms Appendix" (1991). The spider-humanoids have generally been a Realms creature, featuring in bestiaries and histories for that setting. However, they also received a more generic "Ecology of the Chitine" in Dragon #223 (November 1995), which introduced the choldrith, or chitine priestess. This is their major adventure appearance. When asked about pronouncing their name Cordell says that he "can't be 100% sure of the original designer's pronunciation", but he prefers "KI-TEEN". About the Creators. By 1999, Cordell was one of D&D's most prolific writers. He'd previously authored many slightly related adventures, such as The Gates of Firestorm Peak(1996) and the sahuagin (1997) and illithid (1998) Monstrous Arcana adventure trilogies. This conversion guide allows DMs to run the original module with 5th Edition rules. To use this conversion guide you will need a copy of The Shattered Circle, originally available in hard-copy and now for sale in Digital format at the DMs Guild. This adventure is a generic adventure, not specifically based in any existing setting. Suggestions are given in the conversion guide to place the adventure in the Forgotten Realms.

A local priestess, however, wonders if the heart of the darkness consuming the town lies in a necromancer slain nearby only a few months ago...

"As you approach, the miners themselves appear from their hidey-holes around the ruined camp. They are haggard and hollow-eyed, barely able to lift the picks and shovels they've clearly been using as weapons. They are unwashed, muddy and stinking - they look little different to the undead that they have been fighting. Shrouded in damp blankets and shivering, they stare at you silently, even disbelievingly. There is only one left among them who appears to have a little iron left in his spine. He tightens his grip on his pick and steps forward. 'Are you here to help?'" Some doors should never be opened... A group of miners uncover a dark secret and find themselves fighting for their lives as the dead walk again. Can the party rescue the survivors and stop an ancient evil before it spreads across the land? Doorway to Darkness is a 3-5 hour adventure for characters of 2nd-3rd level.
