Coronatite (コロナタイト Koronataito) is a legendary mineral able to generate huge amounts of heat indefinitely.[1]
Overview[]
The rare mineral can burn forever like a miniature sun, so to those who are capable of reducing it to a stable state for extraction, transport, and processing, it can be used as the power source that doesn't need replacement. Accordingly, artisans and scientists with the right skills and knowledge may use it for building Coronatite Golems or larger machinery.
However, carelessly exposing Coronatite to flames even as small as a lit cigarette may agitate it into a volatile state. If the heat it consequently generates cannot be released in time, then the Coronatite will turn unstable before violently exploding with the force of a powerful bomb, which in the case of the one used for powering the Destroyer would be big enough to obliterate Axel.
