The Ethereal Plane is a ghostly realm that exists as a buffer between the Material Plane and the Shadow Plane, overlapping each. A traveler in the Ethereal plane experiences the real world as if the world were an insubstantial ghost, and can move through solid objects without being seen in the real world. Strange creatures dwell in the Ethereal Plane, as well as ghosts and dreams, many of which can sometimes extend their influence into the real world in mysterious and terrifying ways. Powerful spellcasters utilize the Ethereal Plane with spells like blink, etherealness, and ethereal jaunt.

The Etheral plane is also home to the Radiant Citadel
