The Fairy Kingdom is one of those places where hope is expected to triumph over experience. Unlike on Earth where so often experience tramples hope.
Forget it. You are either going to dance to your death if you wear a rather special pair of red shoes or you hope and pray your glass slippers are not going to break and splinter as all the little pieces will go straight into your foot.
You will be accompanied by talking animals, someone magical who does not want to draw attention to the fact, or you have the unenviable task of going to a place of utter darkness in order to get rid of a rather troublesome ring. Nobody travels in the magical world for fun.
