Listening to the talk of Saruman's lies, I was put in mind of C. S. Lewis' The Last Battle. When Tirian and Jill show the Dwarfs (yes, Lewis uses Dwarfs) that the Aslan they've been obeying is a fraud, they react by rejecting the entire concept of Aslan and refusing to believe that Tirian is, in fact, Tirian. "No more Aslan, no more Kings, no more silly stories about other worlds." The Ape's lie seems to have undermined the entire belief system of Narnia. Saruman hasn't yet gotten to the point of presenting himself as a spokesIstari for the Valar, but he certainly convinced the White Council that he alone truly understands their modus operandi.
