Planes of existence

Multiple planes of existence exist in the multiverse that this fantasy setting belongs to.

These planes of existence were held together by the great world spire underneath Sigil, the City of Doors.

The world of Toriél laid in the center of this multiverse, and was directly surrounded by its echoes and by the elemental planes. Surrounding this core of realms were the outer planes, divided in the lower planes and the upper planes.

A non-divine person who travelled between the planes was called a planeswalker.

Material plane
The core realms represented the material world, with its many facets. In the true core laid Toriél, the world that Faerun was part of. This realm was known as the material plane. In the material plane, the laws of physics and magic ruled over the wills of the gods. The material plane was the home of many sentient species.

Echoes
Toriél had two 'echoes', the Feywild and the Shadowfell. The Feywild was vibrant and alive and teeming with creation, while the Shadowfell was bleak and a centerpiece of death and decay. Both planes are called echoes because their geography is intrinsically linked to Toriél and to each other.

The elemental planes
Surrounding the material world and its echoes lay the 4 elemental planes of Water, Earth, Fire, and Air. These elemental planes are all linked to the material world and each other, creating interesting bridges between the realms such as the demi-realm of steam where water and fire meet. Bridges between the material plane and the elemental planes can often be found in spaces that embody the elemental plane, such as the inside of vulcanoes to the plane of fire. An example of this is mount Hotenow in Northwest-Faerun.
