THE PRIME MATERIAL PLANE IS FORMED OF SOLID MATTER. THE OUTER PLANES ARE FORMED OF BELIEF. THE INNER PLANES…ARE.
Beyond the Prime's infinite crytal spheres, beyond the endless realms of the Outer Planes, lies the absolute reality of the Inner Planes. The cornerstone planes of Air, Earth, Fire, and Water are the most well-known Inner Planes, but they're only the beginning. From the deadly purity of the Positive and Negative Energy Planes to the unbearable filth of the plane of Ooze to the eternal storm of the plane of Lightning, the Elemental Planes are the substance of existence itself. These eighteen planes form the foundation of the entire multiverse; they are the cauldron from which all energy and matter are brewed.
The Inner Planes details the Elemental, Paraelemental, Quasielemental, and Energy Planes. Surviving these planes can be a challenge, but within these pages DMs and players learn how characters can adventure among the unearthly locales and strange denizens.
