Book of the Planes
This fantasy role-playing supplement details the elemental, transitive, energy, Astral, and Outer Planes, with rules, hazards, encounters, and adventure ideas for journeys between them. It introduces ten new Outer Planes, including a realm of awakening horrors and a land of living stories, and offers guidance for fitting them into a campaign cosmology. Rules for planar traits and planecrafting let characters create or alter planes. The book also covers planar travel, magic, Nexus pocket worlds, and organizations with their own agendas.
