The elemental planes are inner planes that embody the elemental forces. These planes are arranged in a non-Euclidian fashion so that each plane touches its two neighbors, avoids its opposition element, and touches the energy planes.
Pure elemental planes[]
The pure elemental planes embody the four basic elements of the D&D setting. Beings that originate from one of these planes are known as elementals.
- Elemental plane of air
- Elemental plane of earth
- Elemental plane of fire
- Elemental plane of water
Para-elemental planes[]
The para-elemental planes are formed where two pure elemental planes meet. Beings that originate from one of these planes are known as para-elementals.
- Para-elemental plane of ice (air/water)
- Para-elemental plane of magma (earth/fire)
- Para-elemental plane of ooze (earth/water)
- Para-elemental plane of smoke (air/fire)
The arrangement of the pure and para-elemental planes can roughly be pictured as follows:
| Ice | Water | Ooze |
| Air | Earth | |
| Smoke | Fire | Magma |
Quasi-elemental planes[]
The quasi-elemental planes are formed where the pure elemental planes meet the energy planes. Beings that originate from one of these planes are known as quasi-elementals.
- Quasi-elemental plane of lightning (air/positive)
- Quasi-elemental plane of minerals (earth/positive)
- Quasi-elemental plane of radiance (fire/positive)
- Quasi-elemental plane of steam (water/positive)
- Quasi-elemental plane of ash (fire/negative)
- Quasi-elemental plane of dust (earth/negative)
- Quasi-elemental plane of salt (water/negative)
- Quasi-elemental plane of vacuum (air/negative)
The arrangement of the quasi-elemental planes can roughly be pictured as follows:
| Negative | Salt | Water | Steam | Positive |
| Dust | Earth | Minerals | ||
| Ash | Fire | Radiance | ||
| Vacuum | Air | Lightning | ||
