Spirits

Spirits are the souls of the ones who died in Grace Kingdom.

Background
Spirits lives inside the Darkwood, and they hate any outsiders. They hold a great amount of knowledge even knowing that Six was from another planet. Spirits talk in the language of the Tounge or language of the gods.

Once a year, during the Undead Festival, the spirits of the ones who died in Grace returns, possessing anything, by human corpses or dolls.

There are those who make friends with spirits and fight using them, they are called spirit knights and are very rare in the world. It's possible to control them by using earth-magic.
