Eberron sits on the material plane, which is one of a myriad of planes of existence. Scholars speak of other planes of existence that orbit the material, or prime plane. As these planes draw closer to the material plane, they become coterminous. This act affects Eberron, infusing the material plane with the aspect of the plane becoming coterminous. As the same plane becomes remote, Eberron is also affected, as the aspects that embody the plane become subdued. For instance, when Risia, the Plain of Ice is coterminous with Eberron, then areas of cold become colder; when Risia becomes remote, then areas of cold become less cold.[1]
3rd Edition Cosmology
Eberron sits upon the Material Plane. Within the Material Plane sits three other planes: the Astral Plane, the Ethereal Plane, and the Shadow Plane.
Orbiting Eberron are the thirteen planes:
- Daanvi, the Perfect Order
- Dal Quor, the Region of Dreams
- Dolurrh, the Realm of the Dead
- Fernia, the Sea of Fire
- Irian, the Eternal Day
- Kythri, the Churning Chaos
- Lamannia, the Twilight Forest
- Mabar, the Endless Night
- Risia, the Plain of Ice
- Shavarath, the Battleground
- Syrania, the Azure Sky
- Thelanis, the Faerie Court
- Xoriat, the Realm of Madness
The thirteen planes are separate from each other, though travel between the planes is possible. They are all connected to the Astral Plane, but are cut off from the Ethereal Plane and the Plane of Shadow; thus spells that allow travel to either of those two planes are unavailable when on one of the 13 orbiting planes.[1]
Wizards of the Coast has developed an online orrery that will show the relative positions of the planes.
4th Edition Cosmology
When the Progenitor Dragons, Siberys, Eberron, and Khyber fought each other, their combat stretched out across existence. After the combat, Siberys' was spread amongst the stars, while Eberron encased Khyber within. Scholars believe this extends to the cosmology as well, where some planes exist with the Siberys, the Dragon Above (the Astral Sea, also called the Sea of Siberys), some with Khyber, the Dragon Below (the Elemental Chaos), and some with Eberron, the Dragon Between. Each of the 14 planes that orbit Eberron are tied to one of the Progenitor Dragons.
Siberys, the Dragon Above:
- Baator, the Nine Hells
- Daanvi, the Perfect Order
- Irian, the Eternal Day
- Lamannia, the Twilight Forest
- Mabar, the Endless Night
- Shavarath, the Battleground
- Syrania, the Azure Sky
- Xoriat, the Realm of Madness
Eberron, the Dragon Between:
Khyber, the Dragon Below:
Those planes of the Dragon Above are the home to angels and demons. Those planes of the Dragon Between (called the Coils of Eberron) superimpose over the prime plane. Those planes of the Dragon Below favor cold, fire, and storm.[2]
