The book has many non-human magical characters. Some of them are from mythology and others Rowling wrote herself. Some of these magical creatures have their own culture and some are like animals. According to the real-world book, "Fantastic Beasts and Where to Find Them", the Ministry of Magic makes three groups of creatures: Being, Beast and Spirit. Beings are creatures like humans and house elves, who are smart enough to manage their own business and Beasts are not.
