In the [[Dungeons & Dragons]] [[Planescape]] [[campaign setting]], there are Elemental [[Plane]]s corresponding to each of the four classical elements, [[Elemental Planes|Paraelemental Planes]] at the boundaries between neighboring Elemental Planes (Smoke between Fire and Air, Ice between Air and Water, Ooze between Water and Earth, and Magma between Earth and Fire), and [[Energy Planes|Quasielemental Planes]] at the boundaries between the Elemental Planes and the Positive and Negative Energy Planes:

Yes, some grid-filling psychoes have been crazy enough to figure out what the quasielemental/paraelemental planes (that is, the Positive and Negative Energy versions of Smoke, Ice, Ooze and Magma) are. It's never been done officially, though.

It is from these planes that magic-users draw to manifest most of their effects: healers pull from the Positive Material plane to treat injury and illness, wizards pull fire and lightning from the requisite planes, and dispelling magic or creating undead means pulling from the Negative Material. Most planes are inhabited by elemental creatures, though those of the "pure" planes tend to be stronger while those of the Paraelemental Planes are mostly weak mephits. Some elementals are intelligent and sapient, and, with the right protective spells for both parties, capable of interacting with and enjoying the company of the "muddled" creatures of the Prime Material planes. [[Monstergirls|Yes, in ''that'' way too.]] A creature with elemental parentage is called a [[genasi]].

The most powerful of all elemental creatures are the [[Archomental]]s, known in earlier editions as the Elemental Princes (or, more commonly, the Princes of Elemental Evil/Good) and in 4th edition as the Primordials.
