Elemental planes

From AJS.COM

The elemental planes are the inner planes within the wheel of the Greyhawk cosmology in the Greyhawk campaign setting for Dungeons & Dragons. The surround the material plane and represent (and perhaps act as the source of) the elements that make up the physical matter of the world.

Primary planes

There are four primary planes that make up the elemental planes:

• Elemental plane of fire
• Elemental plane of air
• Elemental plane of water
• Elemental plane of earth

Demi-planes

There are also many (infinite?) demi-planes that combine the essence of the primary planes, and in some cases further with the energy or material planes.
