The city that was formerly where today is the forest of witches, is covered entirely by a large number of underground passages, which were connected to each other through various tunnels or passageways. All of these underground tunnels run through the entire Witches Forest below, and it's the only way to get into the Witches' realm without being affected and killed by the mist that covers the entire witch forest and kingdom. However, the path through the underground tunnels is not unprotected because witches know that it is the only way in which intruders can sneak in, therefore various creatures in the service of the queen, such as the guardian of the pendulum, guard the tunnels.
