Four doors of mystery appear in the Cage. They lead to four adventures, if a basher has the dark of them. "These aren't doors in the traditional sense, cutter, but they're portals just the same. They appear for a short time every 500 years, popping up in different parts of Sigil. Each hides a mystery that's waiting to be solved, and together they just might hold the key to a secret of the multiverse. All a body's got to do is tumble to the right keys, open the doors, and face down the Unknown." - Estavan, merchant lord Doors to the Unknown is a collection of four Planescape adventures that can be played separately or as a mini-campaign. When four doors appear in the Cage, the barmies crawl out of the shadows, and the heroes get drawn into events that could have consequences for the entire multiverse. Each door leads to a different plane and a different deadly challenge for the player characters. Together they offer a way to stop an ancient menace before it strikes again.

"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.

They are to follow an invisible bridge until they arrive at a hole in the sky – and then jump through.

The End of the World Is at Hand! A hideous death cult has seized control of an ancient artifact-monument known as Tovag Baragu. The power behind the cult is the Old One himself, Iuz the Evil, demonic master of an empire. He's on an all-or-nothing quest for supremacy over the world—and the heavens beyond. To stop him, heroes must face horrors never dreamed of, journeying to a shadowed city where Death rules and the living cower. Here, Iuz will achieve his mad dream by destroying the imprisoned master of that alien citadel: Vecna, the mightiest lich, an immortal demigod. Two items exist with the power to stop Iuz—the Eye and the Hand of Vecna—but using them carries fantastic risks. Not even the gods know what will be unleashed when these items are fully activated. Die Vecna Die! takes the heroes from the Greyhawk campaign to the demiplane of Ravenloft and then to the Planescape city of Sigil. However, none of the material from those settings is required for play. TSR 11662

Iggwilv. Orcus. Maleanthet. Obox-Ob. Charon. These names are among the most notorious in the multiverse, appellations belonging to some of the most dangerous and powerful creatures on the lower planes.

Their lairs are notorious as they are: the River Styx, beautiful but deadly Shendilavri, the Gray Wastes of Hades, frozen Thanatos, and mind-numbing Zionyn.

The town of Cauldron has been saved from volcanic apocalypse. The heroes of Cauldron have earned their place in history, and more than deserve a time of rest, yet fate is not so kind.

Magical soul gems have been stolen from the secret vault of the goddess of death and scattered across the planes. Some want these gems to unlock the secrets of the multiverse. Others want them for personal power. Still others want them to resurrect a fallen deity. As the god of oblivion looms near, can the PCs retrieve the gems from their new owners in time to save their world? Beyond the Vault of Souls is a planar adventure for 9th-level characters, compatible with the 3.5 edition of the world’s oldest roleplaying game. Within you’ll visit the Eternal City of Axis, brave the dangers of the Abyss, and match wits with the torturer daemons of Abaddon.

The battles of the Blood War have raged for longer than mortals have known life, the conflict's savagery and hatred fueling the dreams, desires and obsessions of the multiverse. One way or another, the war spills through all the layers of existence, and little escapes its influence. Some clashes have consequences that shake the Lower Planes. Others are far less meaningful - they're fought solely for the sake of violence and killing. "The Field of Nettles" is set in the aftermath of an especially pointless battle. The adventure rips the player characters from their comfortable lives and thrusts them into the Blood War full force. The goal is to cross one of the more infamous battlefields, seeing the scope and the power of the fighting - and hopefully coming away with a greater understanding of just how big the Blood War is. The adventure is designed for a party of 4-6 PCs of 5th-8th level. The characters don't get to save the multiverse, nor do they find the key to unlock the dark of any great secrets. But they might come to realize their importance (or lack of it) in the scheme of things. On the fickle borders of the planes, that can be worth almost as much.

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?
