14.1 Expanding the Cosmology

Rise normally assumes there is only one Material Plane containing a single solar system. As a GM, you can decide that there are multiple independent Material Planes. You can also add multiple solar systems to a single Material Plane if that suits the needs of your campaign. Technically, that should be unstable since the solar systems should be pulled towards each other by gravity over time. You can handwave it by saying that magic keeps the systems apart. Alternatively, you can simply trust that your players will not scrutinize the physics of that universe too closely.
