This is a Cabin for children of the 'minor' goddess Hecate, who is the goddess of magic, witchcraft, the night, moon, ghosts and necromancy. Children of Hecate can control the Mist and are the only demigods that can 'truely' use magic. The cabin is made of stone that has magical writing on it. It is said, that if one of the stones falls from the cabin, it explodes or causes everyone within a half-mile to turn into a tree.
