From publisher blurb: There has always been something enticing about end-of-the-world stakes, and something even more fascinating which compels us to tell stories about what happens when the heroes lose. Why did everything fall apart, and who are the survivors that somehow endured the end of the world? The Cataclysm Handbook is filled with options for apocalyptic and post-apocalyptic games, with magic that could destroy entire worlds or rebuild them. Horrifying new abilities serve as the bases for villainous or antiheroic characters, for how long can heroism last when civilization lies in ruin? Regardless of how grim or optimistic you wish to be in your world, I hope that you enjoy the myriad of options provided for such ruinous adventures. For use with Pathfinder 1st edition and the Spheres of Power and Spheres of Might systems.
