The lines between beings and creatures are not as clearly drawn in Middle Earth as they are in our society. In Middle Earth, there are beings, creatures, and those that fall in between. The Hobbit and Lord of the Rings stories that Tolkien wrote, and the many movies based on them, all focus primarily on the beings of Middle Earth, though fans encounter creatures along the way. While these creatures may not all play particularly essential roles in the story, they all contribute to the vibrancy and magic of Middle Earth, and they commonly reflect the themes of the stories.
