Dark spirits are the beings that have inherited the dark power. There are 2 beings divided by the magical strength of power. One is divine—the pure and holy side of magic. Another one is Dark—the impure and bad side of magic. Both are equally important in the world. But few breeds of dark magic are harmful to commoner beings. They are demon beasts, dark spirits, and sirens. Dark mages are more like the divine mages. That's why there are countless academies in the world for those who have a dark aura in their hearts and have possessed dark magic. Divine possessors are sent to the church to control and use their power for good.
Demon beasts are like the wind of the world. Can't be seen but feels. Normal people and divine possessors can't see them. Only people who possess the dark magic can see them. It's hard for those countries that have only people of divine possessors and rarely have dark possessors.
