The Feywild is one of the Planes of Existence in Azimuth. It is a marvelous and magical reflection of the Material Plane.
The Shadowfell is one of the Planes of Existence in Azimuth. It is a distorted and colorless reflection of the Material Plane.
The Ethereal Plane is one of the Planes of Existence in Azimuth. It is one of the Transitive Planes, a mostly featureless realm that serves primarily as ways to travel from one plane to another.
The Astral Plane is one of the Planes of Existence in Azimuth. It is one of the Transitive Planes, a mostly featureless realm that serves primarily as ways to travel from one plane to another.
The Severance Tear is the edge of the universe in which Azimuth is found. It is the barrier between this world and all others.
