The Nine Olde Witches were a group of nine witches who established Luna Nova Academy during the 7th century, a time when good magic was abundant in the world. They were very powerful witches capable of using magic without the energy of the Sorcerer's Stone. At some point, they decided to seal the Grand Triskellion inside Arcturus Forest.
