From publisher blurb: Drawn from the entries of the 2015 Spheres of Power Worldbuilding Contest, this 45 page PDF features three entire worlds for your campaigning pleasure! Along with setting info, story hooks, and adventuring guidelines, each world comes with its own set of custom mechanics that can easily be adapted to a variety of worlds, including new magic talents, alternate classes and class features, custom XP systems, and fun alternative methods of item crafting and handling player wealth! Inside this volume you'll find: Grimoire: Featuring new and alternative classes including the Mage, the Wunderkind, the Exemplar, the Shaman, and the Dendrite, guidelines for chapter-based character progression, and a new material: Pirium! First the Strangers came and elevated the animals and taught them magic. Then, the world cracked like an egg as the North Axis was flung into orbit. In this world, adventurers take their place in an infant world struggling through its childhood as numerous new races learn to live with each other, and the aftermath of the world's breaking... Erda: Featuring Paragon rules, coin-less item creation, a handful of new feats and Ki powers, and 3 fully-stated NPCs for use with Spheres of Power! The mad prophet Kothar and his empire march across the land, razing nations to the ground and assassinating any king who would dare to oppose them. With nothing but a handful of refugees and the Bloodmother's united orcish horde standing in his way, the time has come for heroes to choose the course of the world... Irhardt: Featuring the Affinity system that exchanges alignment for elemental focus, several new Destruction talents, and a new race (the angelic aielari)! With their advanced technology, the Zethian Empire has made it their mission to slaughter the divinities. With their Dragon divinities, the Kingdom of Atonia matched them to a stalemate. But now that the Elemental Dragons have vanished, there's no telling what the Zethians might do, or who might have the power to stop them...
