In the world of Edelweiss, all things go hand in hand with the Spirit, who walks on top of the elements and constructs the present world. It seems that there is a hand that is constantly working, subtly tweaking the balance and harmonizing the harmony of all spirits. With the birth of life and the development and growth of civilizational karma, this harmonizing force also gradually disappears.

Many years after the end of the World War, the problem of corruption born from the war became more and more serious, and believers in Chaos went around, creating distorted nodes and corrupting the natural orderly environment in an attempt to “cleanse” the world. The orderly arcanists, who were at odds with Chaos, called on the nations to fight against the corrupters, but no one paid attention to them, and there were even those who cooperated with the corrupters to make a profit.
