Updated 7 June 2015: Added Chapter VI: Law in Chaos
The final Planescape adventure released before Faction War, The Great Modron March is an 11 adventure anthology focusing on the modrons’ eponymous march around the Great Ring.
Updated 9 Jun 2015: Added Chapter VII: Recruiters
The first of several adventure anthologies published for Planescape, Well of Worlds is a collection of nine short, un-releated adventures of varying quality. Some of the adventures set the seeds for later encounters and adventures, and the seventh adventure “Recruiters” includes a brief call-back to Green Marvent and the Illuminated from The Eternal Boundary.
The first Planescape adventure, The Eternal Boundary help set the tone for the later adventures and the setting in general. There are a few inconsistencies and some rough patches (many players have difficulty jumping from investigating deaths in the Hive to sneaking into the Mortuary) but overall it’s a good start to any Planescape campaign.
Addle-pated, cook at the Cold Bowl soup kitchen, and Factol Lhar.
Factol Ambar Vergrove, the tiefling Zena, friend to all animals, and the voadkyn shaman Ombidias.
Factol Terrance of the Athar, Terrance’s protegé Caylean, and the factotum Hobard.
Modrons are native inhabitants of Mechanus and the purest examples of the lawful neutral ethos. They popped up here-and-there in a couple of Planescape adventures, but took centre stage in the The Great Modron March adventure anthology.
Daemons (or yugoloths, if you prefer) for Pathfinder Planescape that have no official Pathfinder RPG updates.
The charitable deva known as Unity-of-Rings is the thematic counterpart to Rule-of-Three: both are well-known dispensers of cryptic advice, but while there’s always a price for Rule-of-Three’s advice, with the deva there’s never a price. This makes some cagers even more nervous about Unity-of-Rings’ true motives.
The enigmatic sage Rule-of-Three dispenses cryptic advice from the Styx Oarsman, a shadowy kip in the Lower Ward that caters to tanar’ri. He didn’t figure heavily into the published modules during the initial Planescape run, although he was featured in the adventure Nemesis from Dungeon Magazine #60. He was a major player in the v.3.5 mega-adventure Expedition to the Demonweb Pits.
