Fairytown was an extremely particular wizard union in the southern region. Or rather, it was a concept. It consisted of a number of wizard organizations who were willing to admit the concept. There were also some weaker organizations who joined the union for protection, against the powerful ones around them.
Greya's organization was called "Candy House in the Woods". Candy House joined Fairytown 400 years ago and was still a unique organization among all organizations under Fairytown because most gourmet wizards in the southern region originated from it.
The difficulty for gourmet wizards to break through was among the worst in the entire Occult Art. There had been less than ten gourmet wizards that explicitly showed themselves in the south. Greya was one of the best among them.
