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?

Inspired by the "Happy Fun Ball" from the web series Critical Role, The Cube of Vanya is a magical adventure through demi-planes created by an ancient wizard, now destabilized by a malevolent dragon. The adventurers find themselves trapped within a series of themed planes with no idea how they got there. Navigating these planes to find a means of escape, they uncover the secrets of the cube while piecing back together their own memory. During the campaign the adventurers may fight shadow demons in an inn which is really a prison, flee a tornado while perched perilously in the sky, forge a weapon within a volcano, and much more. The module is structured in a non linear manner allowing the adventurers to choose their own way, or for the DM to pick and choose their favourite bits to highlight. The adventure was written with four level 5 players in mind but it would be easy to tweak for different sized groups around that level.

E2, following up on Death's Reach, the PC's first travel to Sigil following the smuggled remains of the primordial Timesus. The pursuit then leads into the Abyss, through the White Kingdom to face Doresain, the Ghoul King, exarch of Orcus.

Includes a skill challenge for crossing a portion of the Abyss For environments, City refers to Sigil.

Rumors have been spreading in small towns and hamlets, regions isolated in the far reaches of the wilderness and cut off from major cities and trade routes.

Rumors of young men and women disappearing without a trace in the wilderness. Rumors of a cottage that walks on enormous chicken legs. Rumors of Baba Yaga. Those rumors turn out to be true and the Dancing Hut of Baba Yaga has come once again to haunt, confuse, befuddle, and terrorize the far corners of the land.
