Cosmology

Before designing your campaign's first world, you should first consider the nature of its larger system and what that might mean for the planet. While most traditional heliocentric star systems like the Pact Worlds make developing your world as straightforward as taking cues from the real world, other system compositions are possible, either through quirks of physics or the intervention of powerful deities. Other alternatives to traditional heliocentric star systems can be found under Composition of Space.
