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?

"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.
