Milk is what people use to see magical creatures in their true form instead of a non-magical human/object. For example, seeing Hugo as a golem instead of as a pile of rocks. Milk comes from milch cows. One example of a milch cow is Viola at Fablehaven. Other things can be used to see magical beings, such as butter from a certain kind of walrus, and a special kind of eyedrops. Milk can also come in the form of chocolate (the chocolates that Kendra and Seth ate in Fablehaven).
