I walked by a house today and saw a beautiful wardrobe in one of the windows. I broke into the house and opened the wardrobe and ran inside… it didn’t work. Though the books you guys recommended CLEARLY INDICATED that this was a method of inter-dimensional travel. It doesn’t look like that source was reliable.
However, a new potential lead. Someone told me about a girl who traveled to another world by walking through a mirror. I’ll be gone for a bit to see if I can locate a mirror like this. I’ll respond to you all when I finish my quest (unless I’m successful).
