Thing is, Tolkein didn't leave *anything* to chance. He spent weeks getting the moon in the right place in the sky for on the right nights for everyone, scattered all over Middle Earth -- and, of course, he wrote several full languages for the various creatures. Apparently Tolkein -- as a boy -- had written several languages, but his parents threw that "rubbish" out when he moved from South Africa to England. If the Eagles could have taken on Sauron directly, that wouldn't say much about Sauron's power, would it?
