The interior of the witches' castle is very similar to a labyrinth. There are no indications of any kind, and all entrances and exits are built on the same rocks. Some of the entrances are shaped like a skull. However, the inside of the castle, were once the ancient catacombs of the ancient human empire, which after being conquered by witches, was left in ruins. Through the corridors of the castle, are guarded by the Pendulum Gate Keeper , a witch capable of manipulating the mind of her victims through hypnosis thanks to her pendulum clock in the shape of a scythe.
