You may remember the funny introduction to Fantastic Beasts & Where to Find Them where Scamander writes about how hard it has been to figure out what is a beast and what is a magical being. Well, John and I have been wrestling with the same question because we’ve been trying to sort our pages out. My “Magical Being” page had info on animals like Lavender’s rabbit, and so on. Anyway, John and I have revised several pages to straighten all this out.
