Document 11: Magical creatures in Harry Potter: Magical creatures are a colourful aspect of the fictional wizarding world contained in the "Harry Potter" series by J. K. Rowling. Throughout the seven books of the series, Harry and his friends come across many of these creatures on their adventures, as well as in the Care of Magical Creatures class at Hogwarts. Rowling has also written "Fantastic Beasts and Where to Find Them", a guide to the magical beasts found in the series. Many of these are derived from folklore, primarily Greek mythology, but also British and Scandinavian folklore. Many of the legends surrounding mythical creatures are also incorporated in the books. "Children ... know that I didn't invent unicorns, but I've had to explain frequently that I didn't actually invent hippogriffs," Rowling told Stephen Fry in an interview for BBC Radio 4. "When I do use a creature that I know is a mythological entity, I like to find out as much as I can about it. I might not use it, but to make it as consistent as I feel is good for my plot."

Document 14: List of Narnian creatures: Narnian creatures are any non-human inhabitants of Narnia, the fantasy world created by C. S. Lewis as a setting for his "The Chronicles of Narnia". This is a series of commentaries on the creatures of Narnia. Entries include information on physical, habitual, and behavioural elements of the creatures, as well as noting any important members of the species. Each commentary draws on specific references and citations from the books and officially sanctioned Disney films. Many animals that are found in our world are also present in Narnia, and some species include talking variations. At the birth of Narnia, Aslan the lion stares at certain animals and breathes upon them. This enabled them to think and talk in a manner similar to humans, and also altered their size (MN). Smaller talking beasts – such as rodents, birds and small mammals – are generally larger than their non-talking counterparts, whereas larger talking beasts are generally smaller than average . There is never any mention of talking fish or insects, although there are Naiads, or water-spirits. Lewis freely drew on various sources for inspiration; the creatures contained in this list include many from classical mythology and English folklore.
Document 15: Religious debates over the Harry Potter series: Religious debates over the "Harry Potter" series of books by J. K. Rowling are based on claims that the novels contain occult or Satanic subtexts. A number of Protestant, Catholic, and Orthodox Christians have argued against the series, as have some Shia and Sunni Muslims. Supporters of the series have said that the magic in "Harry Potter" bears little resemblance to occultism, being more in the vein of fairy tales such as "Cinderella" and "Snow White", or to the works of C. S. Lewis and J. R. R. Tolkien, both of whom are known for writing fantasy novels with Christian subtexts. Far from promoting a particular religion, some argue, the "Harry Potter" novels go out of their way to avoid discussing religion at all. However, the author of the series, J. K. Rowling, describes herself as a practising Christian, and many have noted the Christian references which she includes in the final novel "Harry Potter and the Deathly Hallows".
