Question: I still don't know this but why EXACTLY are the elves leaving Middle Earth?
Answer:For various reasons. Because with the distruction of the One Ring the protective powers of the Three Rings of the Elves diminished, because their fate is not bound with that of Middle-Earth's which means they can take the straight road to the Undying Lands instead of having to remain in Middle-Earth until its end. Also, if they remained in Middle-Earth they would eventually diminish, so they left for the Undying Lands where they would be immortal (Elves are not immortal in Middle-Earth, they just age *very* slowly, but in any case slowly enough to be considered immortal by the race of Men).
