[@Regitnui] Not quite how aether works.It's an omnipresent, perfectly elastic medium having zero density, according to Christiaan Huygens, which is the best way I can find to describe it. It's like hard air. Manipulatable, magical, hard air.

You could use air, with the sub-specialization of pressure. Aether is problematic, in that it has been described as the 'air that gods breathed', as as the superior element to the classical four, called the quintessence from which words like quintessential (all important) come from. It's been described as the medium through which gravity and/or light and/or magic travel through and is associated with the philosopher's stone which can violate natural laws and grant immortality. In other words, it's a god element that probably should not be used lest people's eyebrows be raised.
