Elemental Planes

Not actual places per see, the Elemental Planes refer to theoretical dimensions which would only consist of air, earth, fire or water.

Description
Rather than being otherworldly dimensions “the Elemental planes” is simply a scholarly form of referring to the natural state of the elements. Although a common misperception among less educated individuals there are no actual Elemental planes. However, the magical energies associated with the four elements are interdimensional and might be found on all planes. Thus some scholars argue that there actually is an Elemental plane that encapsulates all the other planes of existence. The elemental schools of magic include aeromancy, geomancy, hydromancy and pyromancy.

Different locations can be spoken of as being closer or farther to a specific Elemental plane. This is again simply a way of saying a certain element is prevalent or absent in an area.
