The White Grimore

In the world of Lotov, magic is obtained through grimoires' which appear after one's 12th birthday. They tell what level and skills the person has, and can only be read by the owner. Supposedly, the darker the color, the more powerful the user is. The color white is known to be a curse and is associated with the "demons." Had anyone with white hair be found out, them and their entire family would be burned at the stake.
