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!

A series of short encounters and story hooks that may cause your party to question the safety of their local tavern… Designed for characters of all levels

Far in the future, bards sing tales of kings and conquerors from ages past - but from your present. The Hero-Kings of legend are your player characters from your campaign, who even now shape the course of Cerilian history. More than simply an adventure collection, this 160-page book enables you, the Dungeon Master, to turn ordinary domain actions into oppurtunites for heroic exploits. Each of the eleven "legends" set forth here is based on a different random event from the BIRTHRIGHT Rulebook. Don't allow a mere die roll to decide the outcome of a blood challenge, rebellion, intrigue, or magical event - make the PCs forge their own destinies by confronting a madman who is "Blood Hungry," wresting the "Fang of Kriesha" from its evil wielder's grasp, thwarting a rival regent's "Double Dealing," and saving all of Cerilia from "The Gift of Azrai." These adventures are suitable for PCs of all levels and classes - wheter regents, scions, or commoners - and can take place wherever you campaign is set. This book also includes an appendix that offers advice for running different types of BIRTHRIGHT campaigns and creating your own adventures fit for a king. TSR 3125

THE NEXT MARCH WASN'T DUE FOR ANOTHER 189 YEARS. TRY TELLING THAT TO THE MODRONS! On a regular schedule, the Great Modron March spills out of Mechanus, and the lawful automatons files their way around the Great Ring. No one knows why they do it, but everyone stays out of their way - because when the modrons march, they'll walk right over a berk who doesn't know enough to move aside. But this March has started decades before it was supposed to begin, and that's even more of a mystery. Caught unprepared, the planes shudder under the modrons' collective footsteps - and even the modrons themselves seem a little out of sorts. The Great Modron March anthology features 11 adventures for characters ranging from 1st to 10th level, as well as new information about the modrons of Mechanus. Each adventure can be played separely or linked together to form an extended campaign. The modron procession touches every Outer Plane in turn - and it isn't always welcome. On their unswerving path, the clockwork creatures will destroy celestial towns, be attacked by evil knights intent on using modron parts in foul experiments, and lead characters onto the deadly plains of the Abyss and into the famous prime-material labyrinth of Undermountain. Without help, they'll be lost in the swirling chaos of Limbo or even fail to complete the March entirely. And along their route, every blood on the planes seeks the answer to the most important question: Why have the Modrons abandoned their normal, lawful schedule to march years before they're due?

For months, the dreams of the people of Emystrell have become dark and terrible. It seems their nightmares have come to life as in recent weeks, people have mysteriously gone missing, vanishing in the night without a trace! Everyone is too paralyzed by their own despair to do anything or venture far from the safety of their homes. Emystrell is on the brink of collapse. The baron is offering a handsome reward to anyone who can show proof of the end of whatever evil curse that has taken hold of their town. This adventure is designed for a party of 3-5 heroic characters from the 2nd to 3rd level. It has elements of mystery and investigation in the first section which can be detailed and highly involved for groups that enjoy the process of searching for clues and solving mysteries or just as easily glossed over for groups that are more tactics focused. The second section of the adventure features the dungeon: a labyrinthine complex of an ancient elven crypt which the thieves guild has used as a base of operations for a decade...until the serpent worshipping cult arrived. The third section of this book is the detailed map and notes on the town and surrounding area of Emystrell. Roleplaying notes are kept light to allow for room for your own interpretations and details to NPCs remain as free to do with as you choose unless I felt inspired and hoped to give you a cool idea. This adventure has hooks for Dungeon Masters interested in a larger campaign involving the sinister plots of the Yuan-Ti (snake people) as well as other interesting adventure hooks (such as the giants in the nearby mountains or the stolen gem: The Eye of the Dragon). These plot points are intentionally left vague for you to fill in the gaps based on what your players seem interested in. You are invited to use this as a launch point adventure to lead your heroes on a larger adventure that might someday set them against an Anathema Serpent demigod, or it may simply be the adventure that begins their journeys and the evil of Yargoth stops here at Emystrell. If your campaign is set in a pre-published setting, this town of Emystrell can be replaced or fit into any campaign with a few tweaks to local gods and names. If you are playing in Dragonlance, you could replace Yargoth the Dread Serpent with Tiamat, or Dendar in Fearun. The local goddess, Tyr, could be the Tyr from the Forgotten Realms or even Norse myth if that is your campaign setting.

The party's objective is to steal the gold that a tyrant would use to pay the mercenaries he has hired to take over the town of Elderwood. The adventure plays out as a caper over three in-game days.

"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."
