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?

In this adventure players are set first on a simple task, to solve the disappearance of the local witch before outside forces take an interest. But as the players get deeper, they will rapidly kind themselves on a quest for far more, as they range from an alchemist's lair on a crumbling tower down to a dark swamp full of mystery and danger, seeking a holy relic that might lead them to the outskirts of Hell itself. All in service of the sleepy Village Sujeira and the dusty souls within. 1452: Saving Sujeira’s Soul is an adventure set in northern Portugal on an alternate history Earth during the year 1452, in a world where history is much the same, but for the fact that the Rus are all hirsute dwarves, the hordes that poured out of central Asia were orcish (and half-orcs are mostly janissaries split among the Ottoman Empire’s demesnes), and elves are creatures of rumors and myth. Halflings live among the English and Portuguese in villages and farms, while goblins are pests best left for dead in the wilds between civilized countries. The Church arms its inquisitors with holy blessings, for witches are not mere milk-souring old women but vile devil-pacted souls, and wizards and sorcerers seek human and kine for sacrifices to fuel their darkling magics. There be dragons on the edges of the world, and ogres and sea serpents and giants, but the alchemists of this world know things beyond mortal ken and fight these horrors with science and canny concoctions.
