Aether (Also called Æther and Ether) is the stuff that souls and incorporeal beings are made of. It has no material form, but can potentially alter or affect matter. Aether people are very rare; their souls could be described as the 'most pure', in that they've not been tinted by any other element. Because of this, they tend towards balance... though it could also be said that they have a choice of what to be. They have the potential to act like any other element, and the potential to change in massive ways that certain elemental people would be incapable of. In addition, they can control other elements at a certain degree.
