Brandon Sanderson’s Cosmere RPG is getting new life from a D&D legend

Keith Baker is working on a new genre-hopping game Brotherwise Games teamed up with Brandon Sanderson in 2024 to launch the Cosmere Roleplaying Game, a tabletop game that allows players to have adventures across the prolific fantasy author’s many interconnected worlds and series, such as Mistborn and the Stormlight Archive. That meant devising original rules to enable combat, negotiation, and exploration in settings with very different technology levels and magic systems. Brotherwise announced during the opening ceremony at Gen Con that it is now using that versatility to power new projects, including one from legendary Dungeons & Dragons designer Keith Baker. Brotherwise is following a trajectory similar to Monte Cook Games, which published the science fantasy TTRPG Numenera in 2013 and then broke out its mechanics in the 2015 Cypher System Rulebook. That success has since led to numerous other Cypher-based games, including Old Gods of Appalachia and The Magnus Archives. Brotherwise will be providing free online rules and templates for designing games using the Plotweaver RPG System, the underlying mechanics of the Cosmere Roleplaying Game.
