At the end of time, in C.S. Lewis's fantasy world of Narnia, a tragic thing happens. Actually, there are many tragedies in that story (The Last Battle), but this one is different.
My favorite epic tale is J.R.R. Tolkien's Lord of the Rings. I have read it several times, and even read the whole of it aloud (twice) to my children. It is a well-crafted tale of the conflict between good and evil; of power, corruption, valor and honor.
