Fiction:The Firmament/Ethereal Plane

The Ethereal Plane, also known as the Space In-Between or the Transitional Realms, is the name given to the magical space separating the planes of existence from one another.

Description
The Ethereal Plane is an ethereal, infinite and incorporeal realm of emptiness and pure, raw magical energies. Most of it is made up of empty space, though certain locations hold physical structures where creatures congregate. The Ethereal Plane is fundamental in existence, for it stops the Material Plane, the Elemental Plane, Ziana, the Underworld and Irkalla from colliding, always giving them enough space to grow.

Inhabitants
Innumerable outsiders, unaligned with any greater planes, are native to the Space In-Between. There, these creatures live their equivalent of normal lives.

The Ethereal Plane is the first stop for planar travellers. Creatures who wish to travel to other planes must pass through the Space In-Between to do so, leading it to be constantly travelled by powerful spellcasters, elementals, angels, demons and psychopomps.

The ether wyrms are the True Wyrms native to the Ethereal Plane.

Places of interest
While normally devoid of true locations, the Ethereal Plane holds in it a number of notable smaller planes.
