What makes it “high” fantasy?
If it’s set in a completely made up world that the author “builds”, it’s high fantasy, for example, Tolkien, or David Eddings. If the author’s world is set in what’s basically our world, it’s low fantasy; Jim Butcher’s Dresden Files pops to mind.
Thanks. I do love The Hobbit / Lord of the Rings. Read all the books twice in high school and watched all the movies twice as an adult.
