From publisher blurb:
A Magnificent World of Magitech
Welcome to Vandara, a world where magic and technology have grown as partners rather than adversaries! Forged in an ancient war between interstellar tyrants, where gods are born, ascend, and fade into oblivion with the hopes and woes of their followers, Vandara was poised to conquer the stars before it ambitions fell to ruin with the coming of the Qlippoth scourge. Uniting their skill and will to create the almighty Arcforge, the Vandarans have joined powerful arcana and incredible machines to battle back from extinction… though within their own creations lie the seeds of their ultimate demise.
Spheres of Influence brings you the first chapter of Vandara’s lore, the three great empires of Cidalac, Taurun, and New Estaria that shape struggle for Vandara’s future supremacy, along with the great cities of Balyn and Maytar, whose industry and ideology are the fulcrums are at the heart of Vandara’s many-sided conflicts. In addition, you’ll find a wealth of character options for heroes and villains alike using the Pathfinder Roleplaying Game rules, like the mech-riding Arcforged Champion and Morphmech Renegade, and for the Starfinder Roleplaying Game like the Forgepriest Technomancer and Machine Speaker Envoy. Plus fans of the Spheres of Power and Spheres of Might rules will find tons of new material for those systems, including the world-shaking forces of the Technomancy sphere.
