Millennia ago, aberrations from Xoriat, the Realm of Madness, were driven from Eberron. The Gatekeeper druids–mostly orcs–placed powerful dimensional seals throughout Khorvaire to prevent the creatures of Xoriat from returning. To repair a breach in one of the seals at a settlement called Tjorda, a Sealguard Complex was built. An immortal guardian ws tasked with attending to the repaired crack in the seal. Thousands of years later, the Gatekeeper druids rediscovered the sealed complex. Even without knowing its precise history, they ascertained its sacred nature and have guarded it from then on. Being sealed in to protect the site and commune with the inner guardian is considered a great honor. Much of this history has long-since been forgotten. But 10 years prior to the adventure’s start, Vilda Karrte–a relic hunter with her own agenda–tracks a Xoriat artifact called the Spiral Well to the complex. Turned away by the Gatekeeper, she forces her way inside, grievously injuring them. Having discovered Vilda’s journals, Provost Nigel Faurious, through the Clifftop Adventurers’ Guild Handler Lhara, tasks the adventurers with recovering the Spiral Well.

The Temple of Tesh-Yatra is a setting-neutral dungeon delve for a party of 6th level adventurers, inspired by the classic funhouse dungeons of yesteryear. The dungeon takes 6-10 hours to fully explore. It features a high proportion of non-combat encounters: puzzles, exploration, and the occasional deadly centrifuge. The ungodly fusion of a mad scientist’s lab and a planar temple, the dungeon includes an encounter that can launch your players into the Nine Hells – for a price... The Temple of Tesh-Yatra includes two new constructs to use in your game: the sinister Maimers, and the enigmatic Skorverra; as well as a new magic item: the Amulet of Tesh-Yatra, an artisan’s dream! The Temple of Tesh-Yatra also comes with a VTT battlemap (transparent PNG format). The Temple of Tesh-Yatra was originally set in the Outlands, as an extraplanar dungeon. But given its self-contained nature and the Temple's age, it is well-suited to any wildnerness, and would work equally well seeding a hex crawl.

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?

Leading the experiment is a rogue Modron officer named the Creative Director, who has gone mad and morphed the tests into an elaborate death trap for adventurers.

Who will defeat the Creative Director and put an end the mad tests?

"The longest, and perhaps strongest, AD&D adventure we've ever done." The fabled Mace of St. Cuthbert has been lost from the sight of both human and demi-human for many centuries. Some claim it lies at the heart of an active volcano, guarded by salamanders and flowing lava; others swear it lies buried deep inside the earth, warded by powerful magics raised by those who would see its power denied to the forces of Law and Good. A few assert that it has never left the possession of the Saint, and even now he holds it in his strong right hand. But a few claim that none of these are so that long before the Sainted Cuthbert rose to his exalted station, his mace was hidden away from those who would steal it before he returned for it, hidden away outside the bounds of normal time and space, in a place so outlandish that the Mace's power and destiny would be unknown and unknowable, and thus safe. Pgs. 45-54 & 56-57 & 59-68

For over a decade, mystery has surrounded the fate of the lost goddess of trade and wealth, Waukeen. The Golden Lady disappeared during the Time of Troubles and has not been heard from since. Now, in Marpenoth in the Year of the Tankard (1370 DR), a young prophet suffers from disturbing, divine visions that reveal a beautiful, golden-tressed woman imprisoned on a far plane of existence by some great evil. The leader of Waukeen's church believes that these visions mean Waukeen is alive but trapped in the deadly and dangerous Abyss. A party of adventurers is dedicated to peeling back the mystery of the Golden Lady's fate. Their route takes them to the plane-spanning Infinite Staircase and beyond, to the Abyss, the home of the demonic tanar'ri.
