As a system free setting, you can use it for any of your fantasy games - Pathfinder, D&D, or any other game of your choice. It is a place where you can lose yourself as you explore and discover the many details of the setting, from how the world of Arrasia emerged, the gods, the heavens and hells and the wars that have consumed them.
The Kyngdoms: The World of Arrasia is a classic high fantasy setting, populated with men, elves, and dwarves and chronicles their tales from the beginning of time through to a new age of chaos and war. The depth of The Kyngdoms will allow you to entirely immerse yourself in all the rich detail of this world – from the nations and gods, through to the very history of the world itself.
