King Energy is one of the largest energy companies in the world and a multibillion dollar conglomerate. It deals mainly in coal, natural gas, oil, and nuclear resources, though in recent years it has moved slowly into acquiring a stake in solar, wind, and other renewable markets.

King Energy is based in Queen City, USA, but has branches around the world. The CEO of King is referred to by Shadowthief as the Sharp Dressed Man.

King Energy also actively invests in research and development in many technological and scientific fields. Numerous times in the past, the energy corporation has also attempted to partner with, purchase, buy a share in, or otherwise influence the Knights, politicians, and the city, county, state, and national governments. A recent example of this is their public offer to build the Knights a new headquarters and erect a memorial in downtown Queen City to the fallen Knights.
