It's from a movie. Well, it started off as a bunch of books, The Hobbit and the Lord of the Rings trilogy, and then those became movies. Basically the world we're in is called Middle Earth, and there's humans, elves, and these creatures known as Hobbits, which is what a couple of people have turned into. Basically humanlike but with hairy feet and a hell of a lot shorter. There's also a bunch of things we don't want to run into, like orcs and Uruk Hai and other stuff in Mordor. Depending on when we got here in the storyline we might not deal with any of them.
