Aetherium is by far the strongest metal in the known world and still lighter than steel. Still, it is only known to be found in a single location in the world which is carefully guarded by the Empire's guards. The only people ever to receive any items made with aetherium are those who have done a great service to the Aelyrian Empire and who are being rewarded by the emperor himself.
Aetherium has several unique properties in addition to its resilient golden natural glow and utterly infallible strength. The metal seems to emit a self replenishing inner radiance type spell. It is not however purely a mortal spell, as it cannot be dispelled by conventional means. The same is true for the light regenerative aura that the metal emits through any flesh that it comes into contact with.
It is said that Aetherium is the common building material of the
Aelyrians. It is recognised as the most durable material in the world as it is impossible to break with non-magical means.
