Aether

Aether is a mysterious substance often known as the "Fifth Element" and although it has been utilized since the dawn of human civilization it has never truly been accepted in mainstream society, with many regarding it as a force akin to magic.

In reality however Aether is not mystical in nature, it is an actual force of nature - much like the other classical elements (earth, wind, water and fire).

In its natural state Aether resembles glowing light and can be used to power all manner of machinery and devices such as rayguns, flying-machines or automatons: when superheated Aether has similar properties to lasers (hence the elements use in rayguns).
