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.

For years the Count of Durwall Keep ruled over the land fairly and with justice. That ended during the Bloodrayne Conflict when the castle was felled by troops loyal to General Bloodrayne. In the many years that followed the triangular keep has fallen into a sordid state of disrepair. The keep used to hold mighty coffers of treasure for the Count and for the Emperor as well. A stronghold was built under the keep to secure said treasure and perhaps some treasure may still remain in the depths of its dungeons. Recently it’s been said that the Snaggletooth tribe of kobolds has seized the fortress and is using it as their home. It is also rumored that there may still be undiscovered treasure located in the dungeon of the keep. Faint echoes of the missing Orb of Ruler ship are still heard.

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?
