Just calling where Walker was brought as the mists cleared and he could see more of the endless night forest was too simple. The area that he was brought to was like a guided garden with carefully crafted items made of wood and other smaller materials.
There was a shocking lack of metal when Walker was realizing that there was a greater focus on making more natural homes for the witches to rest in. he didn't see many signs or anything that would know how to travel through here.
"We travel by the feeling and the knowledge we are given on our paths. Our connections with one another allow us to feel where to go without as much worries." The grand witch of decay explained that the witch born race did not need to worry so much because of these reasons.
It was similar to the bonds that he had with Midnight and Onyx. Walker could sense where they were and follow that sense even though they might be too far to communicate in the same ways as others might.
