Among the four elemental planes is a theoretical fifth, ether. Most scholars heavily debate the existence of such a thing as it would completely change all they knew of the elements. One of the most pressing arguments for the existence of this fifth element is the elusive ether elemental: a fuzzy humanoid shape made of violent prismatic energy found roaming the Ethereal Plane. Ether elementals are commonly drawn out by attempts to travel through different planes of reality.
Elemental Nature. An ether elemental doesn't require air, food, drink, or sleep.
