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 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.

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.”
