Etherium

Etherium is a highly flammable liquid element, used as a power source for most modern machinery. It was first discovered in a large amounts underground in Etheria, and very little of the material has been found anywhere else. This monopoly on the trade of Etherium quickly caused the Etherian Empire to become one of the wealthiest in the world. The Etherian Empire's hunger for more Etherium mines is what drove them to venture into the Glass Desert, where they dug too deep into the sands and awoke the Dead God.

Etherium is used for a large majority of lighting systems in the Interstate, the other common element being neon. Since Etherium has a dim orange color, much of the Interstate is lit in an amber glow.
