This is a Magnum Opus. Et Deus, Et Regis is a fantasy world building system primarily based on Dungeons and Dragons to allow dungeon masters and their players the ability to enjoy a detailed fantasy world that will serve as a backdrop as they play out their character's exciting adventures. Et Deus, Et Regis has two main components:
Et Deus is focused on the guidelines to provide the physical characteristics of the fantasy world, covering geography, climate, weather, terrain, natural resources, etc.
Et Regis deals primarily with the culture and society aspects of world building, including guidelines on how to detail the races, cultures, kingdoms, cities, towns, & other population centers of the fantasy word.
Each component can function independently of each other, but will work best when combined.
