=====The Primary Elemental Planes=====
The material that composes these planes are the most familiar elements, from classical alchemy: '''Air''', '''Earth''', '''Fire''' and '''Water'''.  Theoretically infinite in size, it is still possible to travel between them by mundane travel; how to reach the "borders" of such infinite planes is a mystery.  Each plane is dedicated to their material, and the sentients that inhabit these planes are called "elementals" en masse, although the term is usually used for those entities that have extremely simple forms and are summoned to the Prime Material as labour.  You will also find life that approximates Prime Material plants and animals, although Elemental Plane natives will be quick to point out that Prime Material animals are mixed copies of their purer flora and fauna.  You will also find on each of these planes a race of [[Genie|vaguely Aramaic sorcerous giants]], usually at war with those of other elemental planes (the two most familiar species are 'djinni' from the plane of Air and 'efreeti' from the plane of Fire).

Survival on any of these planes is difficult, as life from the Prime planes and many Outer Planes need a mix of elements to survive.  The plane of Air is the only source of something to breathe, although some may find the bottomless falling disorienting, and the plane of Earth is the only source of something to stand on if you count being buried alive as "standing."  The plane of Water is comfortable if you have gills and blubber, and the plane of Fire is delightfully warm for the split second before you are reduced to a cinder.

It goes without saying that the elemental planes are essentially comprised of nothing more than an infinite mass of their own elemental energy/matter spanning in all three dimensions. You can dig or swim "upward" as high as you like on the Planes of Earth and Water and you'll never reach a surface. Only the Plane of Fire has something approaching Prime Material style topography, and that's more of a matter of consensus; the Plane's flames diffuse or compress as one ascends or descends; the "sky" is made of combustible, oft-toxic fumes, fireballs and waves of heat, the "ground" is comprised of burning coal-esque flames with the consistency of water, and the "underground" is flames with the consistency of molten metal. There are pockets of elemental matter from other planes, but, for the most part, it's basically an infinite expanse of one dimension.

Each of these four elemental planes also has two Elemental Lords, one of elemental evil and one of elemental good, who have dominion over all the simple-form inhabitants of the plane and has staggering power and control over the material the plane is composed of.  These are the closest that the Inner Planes have to "Powers," although no Elemental Lord receives supplicants from other planes (all of their followers are already in their plane, and unswervingly faithful), and their influence is limited to their plane and any vortexes (portals that are locked open) that may touch the Prime Material. Elemental Lords are also collectively known as [[Archomental]]s, a reference to their status as "arch elementals".
