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 great evil force descended on the town of Phlan years ago. The townspeople were all either killed or driven away, and Phlan became (literally) a ghost town. Fifty years later, the survivors are ready to reclaim their town. But they need a band of strong and brave adventurers to lead the fight-they need you. Ruins of Adventure is a set of connected short adventures written by James Ward, David "Zeb" Cook, Steve Winter and Mike Breault-four names familiar to all AD&D game fans. It uses the same setting, locations and characters as the classic computer game Pool of Radiance by Strategic Simulations, Inc. In fact, many of the scenarios here in Ruins of Adventure will provide important clues to the successful completion of Pool of Radiance. TSR 9238

From Exalted Funeral: The snows are alive. A soft, cold spirit courses through them. Her lace threads the world; watching, drinking, listening, stroking, soothing, killing. Her touch is soft and icy. She is Winterwhite, the daughter of the Waterdrinker and the Northwind, and she is a terrible god. An avatar of ice and hunger, of visions and death. Dooms and devastations to visit upon a cosy roleplaying setting. Longwinter is the RPG sandbox of a realm that has broken its vows to Winterwhite and will now pay the cold price. This book contains secret knowledge and mechanics for the referee. The setting is profoundly close to that of Witchburner (by the same author and artist). This sandbox includes: ~110 pages of content. some colour illustrations. 3 variations of the Brezim map to represent changes as Winterwhite's curse bites harder. faction trackers for the 5 key factions and over 40 events to represent different groups growing or waning in strength depending on player actions. detailed weather and event tables to simulate a living setting. detailed encounter tables for night and day, which grow harsher as Winterwhite's curse grows stronger. several more tables to generate corpses, caches, vaults, and memories of summer. optional playing card-based escape mechanic with 54 different locations, challenges and characters encountered in each location. alternatively, the escape section serves as a resource to mine for winter locations, challenges, and characters. Be aware: This is a book of factions and winter encounters for the full-fledged mini-setting detailed in the Longwinter: Visitor's Book. The content is mostly system-neutral. It references some 5E or d20-style conventions, but should work with most low-power systems easily. Many of the encounters, and particularly the escape, will not work with characters resistant to cold, capable of flight, or otherwise able to avoid the environmental challenges. Finally, thank you for considering running Longwinter for your players. It is a bit of a tribute to the mountains and myths I've walked and heard over many years, and I hope you will find fuel for many adventures and good memories herein. It has also been a challenging project to prepare. Many people helped make it as good as it is. The fault for all errors and typos is my own. —Luka, December 2020

The Sword of the Dales, an icon of the Dalelands symbolizing the unity and strength of the people, has reappeared! Created by Shraevyn the weapons-mage hundreds of years ago, the lost Sword had become nothing more than a fantastic children's tale - until now. A group of warriors led by Randal Morn, rightful ruler of Daggerdale, rushed to the Sword's resting place to recover it, but dark forces awaited them, and Randal and his men fell to an ambush. Only one man escaped, yet he brought with him the hope that Randal Morn yet lives. Resolved to rescue his leader, that lone survivor turned to the great Elminster of Shadowdale for aid. But Elminster is gone, off plane-hopping while the fate of Daggerbale hangs in the balance. Hence, it is up to Lhaeo, scribe to the old mage, to find a group of heroes who have mettle enough to face down the menace which claimed Randal Morn and his hearty followers... This is the first of three adventures that grant player characters the opportunity to determine the fate of Daggerdale. The saga continues with "The Secret of Spiderhaunt" and concludes with "The Return of Randal Morn." TSR 9484

An adventure in Hyperborea designed for from four to six characters of 6th through 8th level In the far reaches of Hyperborea’s Crab Archipelago lies a small, mountainous island known as Crystal Point. Passing sailors recently have witnessed a crimson glow in Crystal Point’s waters and beams of russet light shining up from its steep cliffs. Too, unusually frequent lightning storms in the area have torn the sky in blinding flashes, shattering the air with their awesome sound. The seedy wharf taverns of Khromarium and elsewhere buzz with these strange tales—some even speculate that Crystal Point may hold the lost treasure of Atlantis! The Lost Treasure of Atlantis takes players into an action-packed realm of adventure: the mythical world of Hyperborea, a sword-and-sorcery campaign setting inspired by the fantastic fiction of Robert E. Howard, H.P. Lovecraft, Clark Ashton Smith, and others. This adventure is designed for Astonishing Swordsmen & Sorcerers of Hyperborea™ (AS&SH™), a role-playing game descended from the original 1974 fantasy wargame and miniatures campaign rules as conceived by E. Gary Gygax and Dave Arneson. Therefore, AS&SH is compatible with most traditional fantasy role-playing games (c. 1974 to 1999) and their modern simulacra, such as OSRIC™ and Swords & Wizardry™.

“The Temple Between” is an adventure for 9th level characters, and it is challenging enough to take them to 11th level by the time all is said and done. Although intended as the final chapter of the heroic tier portion of the Scales of War Adventure Path, it can be run as a standalone adventure, or as an adventure in a campaign of your own making, with a small degree of modification. It contains elements of urban investigation, dungeon delving, and even wartime conflict, making it a suitable adventure to players of many tastes and preferences. The western end of Elsir Vale has been greatly troubled in recent days. The threat of the orc hordes from beyond the Stonehome Mountains, though turned back at Bordrin’s Watch, still lingers in the people’s minds. Peculiar and hostile creatures of shadow lurk in the caverns and caves below. Political squabbling grows among the city’s powerful dwarf clans. All this makes the city particularly vulnerable to an enemy nobody saw coming - that nobody even imagined. This enemy has goals and objectives far beyond the ultimately unimportant Elsir Vale, but the first step is the utter subjugation of Overlook. An enemy who, at least in part, is already here. In this adventure the player characters start by investigating the strange behavior of the city's clergy. They swiftly discover hints of a conspiracy worming its way through the city hierarchy - some members are possessed while others have been replaced by dopplegangers. After trailing this conspiracy to its source they discover a portal that leads to an ancient temple in the mountains. Using the portal, the PCs go to the abandoned ancient temple where they must confront both a cadre of fey and a band of mercenaries, from whom they learn there is a plot for a full-scale invasion of the region! The PCs must them rush back to Overlook and cement their place as heroes as they face off against the invading forces. Pgs. 4-71

Synopsis: Goblin Bathwater, a magical drug, has taken hold in a sleepy coastal town at the edge of the Empire. As the characters investigate the origin of the drug, they uncover an international criminal conspiracy, wild and ancient magic, and a threat to reality itself. Contents: This beautifully made, 54-page adventure offers: A fully fleshed out, setting-agnostic starter area, brimming with colourful NPCs and hooks for adventure. Balanced encounters to bring characters to level 2; then some more devious encounters on their way to level 3. Three mini-dungeons built on the design philosophy of the "5 room dungeon method" Multiple big, cinematic set-piece boss encounters what will make your players feel epic. A facetted intrigue, which does not immediately suggest a simple, ready-made solution but invites the players to come up with their own, personal approach. Why pick this adventure? Hey, my name is Marius. This is my first time publishing on the DMs Guild but I wouldn't call myself a newcomer. I started playing Pathfinder 1e back in 2014. When I took over as our group's DM in 2019, we swapped over to 5e. We have run many, many modules and adventures since. Currently I play three games a week. In short: You could say I'm hooked. I created The Goblin Bathwater Incident as the ideal adventure for in-between your big modules, but it isn't a simple little adventure. With a playtime of about 30 hours, it still manages to hit that sweet-spot, where it establishes context, makes you grow fond of NPCs, and makes those big bossfight wins so much sweeter, all without taking more than a few sessions. The Goblin Bathwater Incident is different from many of the 1st tier adventures in that it pits the characters against traps and monsters, but also asks difficult, open-ended ethical questions, where a simple strategy of "apply sword to head of bad guy" will not cut it.

Weave of the Dread Mythal is a 1st-6th level Dungeons and Dragons 5e campaign that takes players on a journey of peril and intrigue across the Evermoor.

"Mysterious Ways" is a D&D adventure set in the Holy Land (Israel and Jordan) during the time of the Crusades (1114 A.D.) in an alternate-Earth setting. This is a world where the portals to otherworldly realms, particularly the Lower Planes, are closed--sealed shut by the power of the True Cross, a holy relic sought by evil thieves who would see the gates to the Lower Planes flung open. Magic exists in this alternate world, but it is less prevalent than in other D&D campaign settings. This paucity of magic serves the core of the adventure's storyline and should be preserved, if possible. This adventure is designed for a party of four 7th-level player characters (PCs). It is recommended that the party include at least one lawful cleric or paladin. Consult the "Adapting the Adventure" sidebar for ways to incorporate the adventure into generic D&D campaigns and modify it for higher or lower levels of play. Pgs. 84-112

Part 1 of an Expert-level quest into a hostile wilderness. This adventure takes place in the Known World of the D&D game, as outlined throughout the D&D game rule books and modules. The DM may find it useful to consult the Companion and Masters Sets, as well as most of the X-series of Expert Set modules. D&D Expert Set module X9, The Savage Coast, would be especially helpful, as Tortles of the Purple Sage could easily serve and continue that module's direction and plot like, adding a previously undescribed area (the Great Northway) to the Known World. The DM may also place the areas and events of this adventure within an existing campaign setting, as long as the geographical areas of the campaign match those set forth here. Pgs. 40-62
