Magical energy is a force that permeates my world. It exists...well...everywhere! In living things, in nature, in minerals, in the air...

Thirty years ago, mankind learned how to harness that energy using engines powered by crystals that can store and regulate it. It sparked a very sudden advancement in areas of industry and weaponry.

Well, in most of the world. In my country, we devote ourselves to the advancement of art, architecture, music, and philosophy.
