The Planes of Existence

The Material Plane and Its Echoes.
The Feywild and The Shadow Realm are reflections of the Material Plane.
The Transitive Planes.
The Ethereal Plane and the Astral Plane are mostly featureless planes that serve primarily as pathways to travel from one plane to another.
The Inner Planes.
The four Elemental Planes (Air, Earth, Fire. and Water), plus the Elemental Chaos that surrounds them, are the Inner Planes.
The Core Plane
The Core Plane is responsible for holding all of the planes together. The one responsible for this plane has the key to all of the other planes, the world, the multiverse, and every single existence in Aloria.
The Outer Planes.

• The Abyss embodies all that is perverse, gruesome, and chaotic. It is virtually endless layers spiral downward into ever more appalling forms.
• The Beastlands is a plane of nature unbound, of forests ranging from moss-hung mangroves to snow-laden pines, of thick jungles where the branches are woven so tight that no light penetrates, of vast plains where grains
• The Deity Plane is a plane where the deities exist.
• The Door Plane is a plane where many doors can be found.
• Heaven is a good place, where those who have lived a good life go.
• Hell is an evil place, where those who have lived an evil life go.
• The Travel Plane is a plane where those who travel to other planes pass through.

The Life and Death planes.
These two planes enfold the rest of the cosmology, providing the raw forces of life and death that underlie the rest of existence in the multiverse.
