Elemental Plane of Earth

The Elemental Plane of Earth was an Inner Plane or Elemental Plane of the Great Wheel cosmology and the World Tree cosmology models. After the Spellplague, the Elemental Plane of Earth collapsed into the Elemental Chaos, mixing with all the other Inner Planes. Earth is one of the four elements and two energies that make up the known universe and therefore of keen interest to cosmologists. The abundance of large gems and huge ore deposits lured many greedy prospectors to brave the significant dangers of this plane.

Cosmology
According to the Great Wheel cosmology model, the Elemental Plane of Earth could be reached via the Ethereal Plane, an adjacent elemental plane, or by an elemental vortex. If traveling through the Deep Ethereal, a brown curtain of vaporous color indicated the boundary of the Plane of Earth's Border Ethereal region. Once in the Border Ethereal, a traveler could observe the Plane of Earth and be detected by its denizens. Using the spherical model, this plane was adjacent to the para-elemental planes of Ooze and Magma and the quasi-elemental planes of Minerals and Dust. Elemental vortices could occur wherever a high concentration or nearly pure form of an element was found, and could be temporary or permanent. Vortices to the Plane of Earth were nearly always found in the heart of mountain ranges, particularly young ones. Temporary gates could be created by the plane shift spell or the abilities of high level druids.

In the World Tree cosmology model, the Astral Plane connected all planes with the Prime Material Plane and the Ethereal Plane was only used for journeying between locations on the Prime. The Elemental Plane of Earth was not connected or coterminous with any other elemental plane. The spell astral projection could be used to reach the Plane of Earth via a moss granite color pool. Additionally, the gate and plane shift spells could be used to open a temporary portal to this plane, but could be extremely dangerous unless the destination was previously scouted.
