The basic idea is, I've been wondering how much of a difference and what key changes would you see if Saruman the white had not fallen, but rather stayed true? I really like ideas, both in fiction and on historical events, that guess at what may have been had something changed or been different, and was just wondering what would have happened in this case, the main difference being that Rohan would be in far better shape, and Gondor might not be so hobbit dependent to defeat Sauron.
