Darrell Riche, David Roach, and Arnie Swekel. After the typical introduction found in almost all guides of D&D 3rd. Edition, Manual of the Planes presents, in its first chapter, an overview of planes in general: what they are, what their nature is, and what is their function on gameplay. Info about how to shift between planes is also available in this chapter. The second chapter presents hints on how to design your own cosmology of planes, based on the D&D official cosmology known as "The Great Wheel". Generating a personalized cosmology involves several options—for example, consider how magic works if basic planes that feed magic (such as the Ethereal or Astral planes) are disposed of. The next chapters in the Manual are dedicated to detail the Great Wheel and the 27 planes that constitute it, including the Inner Planes and the Outer Planes.
