J.R.R. Tolkien's Lord of the Rings is a complex story made up of countless layers, but occasionally, a fan theory comes along and shifts the whole thing. Of course, this series has been around for nearly a century, so those who love Tolkien's work have had a long time to ruminate about the goings on within the various tales and adventures. With dozens of characters and happenings, there are countless opportunities for developing theories. Some are rather outrageous, while others are entirely plausible. Other Lord of the Rings theories can change how we perceive the overarching stories.
