It is interesting to note this differentiation in Tolkien's Wizards from the usual variety. Tolkien makes it clear through the fall of Númenor that the pursuit of magical arts is forbidden to Men. This is an interesting difference between the Lord of the Rings and other fantasy novels, as all of the mortal characters who the reader can identify with are left with only two things to sustain them: their native abilities and trust in an overall plan that will work things out. They cannot summon powers from beyond themselves to aid in their journey. In fact, even Gandalf does not use magic directly except in very rare circumstances: for instance, when facing the Balrog. Tolkien never trivializes the use of supernatural power in the manner that much modern fantasy is in the habit of doing, and therefore maintains a more serious, thought-provoking story.
