5th edition Player's Handbook (2014) and Dungeon Master's Guide (2014) shifted most of the cosmology of the planes back to the Great Wheel model with some aspects of the World Axis model retained in the descriptions of the inner planes. Great Wheel cosmology The cosmology outlined in the Great Wheel model contains sixteen Outer Planes which are arranged in a ring of sixteen planes with the Good-aligned planes (or Upper Planes) at the top, and the Evil-aligned planes (or Lower Planes) at the bottom. Depictions usually display the Lawful planes (or Planes of Law) to the left, and the Chaotic planes (or Planes of Chaos) to the right. Between all of these sit the Neutral planes, or the Planes of Conflict. The center contains the Inner and Material Planes. One further plane sits in the center of the ring, the Outlands, being neutral in alignment. At the center of the Outlands is a Spire of infinite height; the city of Sigil floats above the Spire's pinnacle. Many Outer Planes were renamed in Advanced Dungeons & Dragons 2nd Edition in the Planescape campaign setting, released in 1994. In the 3rd Edition Manual of the Planes (2001), the old and new names were combined, the Demiplane of Shadow was promoted to the Plane of Shadow, the Prime Material Plane was shortened to the Material Plane, and it was stated that each Material Plane is connected to its own unique Ethereal Plane. The cosmology is usually presented as a series of concentric circles, with alternating spatial and transitive planes; from the center outwards, they are ordered as follows: Inner, Ethereal, Material, Astral, Outer Planes, and the Far Realm. The Shadow Plane and the Dimension of Time, if they are included, are separate from the others, and usually represented as being connected to the Material Plane. Demiplanes, although most commonly connected to the Ethereal Plane, can be found attached to any plane. All planes, save the demiplanes, are infinite in extent. Planes may border (be coterminous) or may be coexistent. In particular, the Ethereal and Shadow planes are coexistent with the Material Plane. In effect, the "boundary" between the two extends through all of space. Thus a ghost in Dungeons & Dragons, which is an ethereal creature, has a location on the Material Plane when it is near the border of the Material and Ethereal planes. It can "manifest" itself into the Material, and
