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 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?

"Orcs have returned to the once quiet border province of Blackmarch. The Bleak Tower and its meager garrison are all that stand against the tide. Their only hope lies in a ragtag band of adventurers willing to venture into the perilous maw of Ironwood Gorge..." "Ironwood Gorge is a fantasy role-playing adventure for 4-8 characters of levels 2-5, designed for older editions of the world's most popular fantasy role-playing game and its clones such as Labyrinth Lord and OSRIC. The material is also easily adaptable to any other class and level based fantasy role-playing game. Ironwood Gorge serves as part two in the Blackmarch sequence of adventures, but is built to function just as well as a one-off adventure, a drop-in-a-hex location for sandbox games, or as a kick start to a new campaign. The module includes keyed maps detailing both the Bleak Tower: a living, breathing refuge for adventurers; and Ironwood Gorge: a cave complex with over 100 keyed areas of traps, monsters and mayhem. The module is illustrated throughout with original artwork and includes appendices detailing new monsters, magic items, and spells. Whether you are looking for an out-sized adventure to usher the hardiest characters to the intermediate levels, or a fully-realized location to plunder for maps and ideas, Ironwood Gorge is a treasure from the old-school of gaming..."

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.

“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
