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!

This module was originally used for the AD&D Tournament at Origins '79. Your party is lost!

The town of Byr is in need of heroes. Residents of the town of Byr have been kidnapped.

Wise rogues join the government, where their larceny has the cover of “legality” and the cash comes in heaps and piles from deceitful receipts and pocketed procurements rather than in small, bloodstained purses from breaking windows, scaling walls, and risking traps and long-fanged guard dogs. Wise rogues do not, by choice, go up against towering giants armed with clubs larger than the tallest rogue in the guild. Nor do they try to nick treasure from dragons without a group of powerful fellow adventurers behind them, who can hurl mighty spells, hack and hew toe to toe with an angry wyrm, heal the injured, and (when things go as they usually do), resurrect the dead. There are wise rogues, and then there are player characters. Emeralds of Highfang awaits them with open arms, offering special challenges and rewards to rogue characters—but as always, the prospects are much better for a party of adventurers from a variety of classes, with wide skills and experience, and of high level. Some might find that a broad base of experience is not only helpful, but essential for survival.

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.

When huge stones fall out of the night sky, A deadly curse settles over Gravencross. Help the village exorcise the Demon Stones. “The sun had set an hour ago, and the rain lashed down and the wind howled on the dark moor. A storm this late in the season was unusual, but this one seemed different. The clouds were more menacing, tinged with anger, the rain colder and more biting than usual. Skerrill had to find the lost calf and get him back to the farm before his father came back from the city on business. He’d been looking for two hours now, and he was right in the middle of the moor when the storm hit. He knew he should have turned back as soon as darkness fell, but then he was never the brightest boy in the valley. If only he had remembered to lock the farm gate. The calf was now likely dead anyway having stumbled among the boulders and rocks, panicking in the dark, and then fallen in a floodwater stream and drowned. Either way, he was in more trouble than he could imagine. Suddenly, a bright flash of white light and a roaring peal of thunder were preceded by an explosion as a huge object fell from the sky and impacted the ground of the moor no more than a stone’s throw from him. Dirt, mud, water, and debris erupted from the impact site, flying high into the air and then covering the moor for hundreds of feet all around. Skerrill was knocked to the ground instantly and covered in the fallout from the blast. His ears rang and his head spun, but he staggered to his feet in a daze. He stumbled to where the blast had happened only moments before, and in a depression in the ground lay a huge stone glowing orange as if hot. Skerrill passed out. Two more thunderous explosions crashed in the distance.”

The Pit of The Oracle is a game module designed for use with the rules of Advanced Dungeons & Dragons. It can be used by itself as a self-contained campaign (or as a springboard to a larger campaign), or it can be easily incorporated into an existing campaign. Comment: Level range is my best guess. Adventure includes a lot of unique short-hand

Welcome to Assault on Gumdrop Mountain. This is designed to be a fairly tough adventure for 5th and 6th level Dungeons and Dragons characters using the 5th edition of rules. In it, the characters wade into such nasty circumstances that only the assistance of a hallucinogenic elixir makes it possible for them to act at full capability. While under the effects of the drug, the characters perceive the world as a candy-infused landscape and monsters as sugary assailants. The adventure is broken into 9 fairly small chapters containing one significant event or a connected series of small events.

"More than five hundred years ago, clans of dwarves and gnomes made an agreement known as the Phandelver’s Pact, by which they would share a rich mine in a wondrous cavern known as Wave Echo Cave. In addition to its mineral wealth, the mine contained great magical power. Human spellcasters allied themselves with the dwarves and gnomes to channel and bind that energy into a great forge (called the Forge of Spells), where magic items could be crafted. Times were good, and the nearby human town of Phandalin (pronounced fan-duh-lin) prospered as well. But then disaster struck when orcs swept through the North and laid waste to all in their path. A powerful force of orcs reinforced by evil mercenary wizards attacked wave echo cave to seize its riches and magic treasures. Human wizards fought alongside their dwarf and gnome allies to defend the Forge of Spells, and the ensuing spell battle destroyed much of the cavern. Few survived the cave-ins and tremors, and the location of Wave Echo Cave was lost. For centuries, rumours of buried riches have attracted treasure seekers and opportunists to the area around Phandalin, but no one has ever succeeded in locating the lost mine. In recent years, people have resettled the area. Phandalin is now a rough-and-tumble frontier town. More important, the Rockseeker brothers - a trio of dwarves - have discovered the entrance to Wave Echo Cave, and they intend to reopen the mines. Unfortunately for the Rockseekers, they are not the only ones interested in Wave Echo Cave. A mysterious villain known as the Black Spider controls a network of bandit gangs and goblin tribes in the area, and his agents have followed the Rockseekers to their prize. Now the Black Spider wants Wave Echo Cave for himself, and he is taking steps to make sure no one else knows where it is." Extra Info from AL.com users: by @marcellarius. "There are a variety of locations in this adventure: the town of Phandalin, a gang hideout, a ruined keep in the forest, a destroyed village, and Wave Echo Cave (a dungeon crawl). The adventure is written in a sandbox style and relies on the players to choose their path. Phandalin offers several side-quests which could serve as hooks for continuing adventures. The premade characters have ties in their backgrounds to NPCs and locations. If you're not using these you'll need to consider other ways to introduce key NPCs."

The ancient world of Harth withers beneath its dying sun…but it’s not dead yet. Welcome to the strange and dangerous city of Carcassay, huddled below the skeleton of a titan rat, sprawling above the ruins of countless dead civilizations. This is where folk come to find wealth, power, revenge, secrets, oblivion… and everything in between. Carcassay is a sandbox city adventure. There are many locations to explore in, around, and under the city. Players can explore any place at any time, and may radically reshape the city’s politics, economy, religions, and physical existence. There are standard dungeons stacked under the city, and GMs are encouraged to keep adding more dungeons… all the way down. Tone. It leans more toward low fantasy or sword-and-sorcery. Most shops look like real shops. Most people look like real people. But strange and horrible things lurk everywhere as soon as you start to scratch the surface. This is my Lankhmar. Carcassay is a vast, bizarre city. It has over 100 locations where you can meet Chaos cultists, Lawful knights, retired adventurers, shopkeepers, brewers, musicians, artists, scientists, hermits, royalty, beggars, doctors, space vampires, eldritch horrors, machine priests, crab colonists, mushroom farmers, mummies, assassins, and diplomats from distant lands… and the moon. And every one of them has goods or services to sell, and a quest (or three) to offer. What sort of quests? Fetch a relic, assassinate a rival, find a relative, steal a soul, implant an agent, cure a disease, stop a riot, solve a murder that hasn’t happened yet, hunt a thief, locate a shrine… the list goes on. And for every Quest, there is a specific Reward: money, weapons, relics, Chaos mutations, exclusive memberships, information, Angelic miracles… the list goes on. This is a place where you can make a lot of money, but also where you can spend that money on interesting goods and services. Factions? We have a few. Seven Chaos cults, five knightly orders, two mercenary companies, four wealthy families, six (seven!) Corpse Lords, foreign diplomats, rival innkeepers, rival tavern owners, plus all the dungeon-delving gangs currently mucking about underground. When you grow weary of all the adventures at ground level, there are three classic dungeons buried under the city to explore. This book contains months (if not years) of campaigning. Enjoy the Chaos.

Provost Nigel Faurious’s continued planar research has uncovered a reference to a sapphire amulet and a map with general directions to the entrance of the Shining Valley deep within the Graywall Mountains. He believes that the Valley is an Irian manifest zone, capable of charging the sapphire and granting unknown healing properties. The Provost has already acquired the sapphire and contracted Lhara, a female shifter within the Clifftop Adventurers’ Guild, to put forth a writ calling for adventurers to follow the map he uncovered and discover if the amulet’s properties are authentic. Unbeknownst to the Provost, a flight of harpies known as the Haunting Song is already living within the Shining Valley after escaping an attack on their lives by two other flights. The characters will have to convince these current inhabitants that they mean no harm. The harpies have already learned the healing properties of the valley and have been raising a new generation without any outside interference, but due to the party’s recent expedition, an oncoming war party has been spotted and the harpies now demand they assist in defending their home.

Things are darkest before they go totally black. He wears black, hires orcs, and looks depraved - but don't be fooled. He's far more dangerous than he seems. Thaddigren Dentiata recently arrived in the village of Sisak, and within 3 months had constructed a great tower on the outskirts. The villagers have become more wary of him, since he employs the help of orc henchment (albeit polite ones), and also is suspected of using dark magic. Since then, livestock has begun disappearing from the surrounding pastures, and two drunk men fell upon a terrible fate when they went to investigate the tower secretly. One was killed and the other remains missing. The villagers have confronted Dentiata, but he and his henchmen politely turned aside their questioning. The players arrive just after one of the town elders was taken by orcs from the village after trying in vain to rally the rest of the townspeople. The players will spend some time in the village gathering information and then attack the tower itself, ending in a final battle with the evil wizard. The module provides details on all buildings in the town as well as all NPCs and stores. Pgs. 6-24
