Well the basic thing is that aparantly, what I can gather, is that the baby is destined to become more, as the quote by the author went "A boy with a destiny... A man with a mission" This boy is obviously destined for great power and as the key, which aparantly symbolizes something larger, to a peice of the boy's life puzzle later on, finds the boy, it teaches the boy his first lessons of greatness, hence the fighting the bats. Still, as he IS after all a boy, the little shadow demons came along and overpowered the boy, still not strong enough as you can see, to do whatever this destiny mission of his is. And the Gauntlet that the voice in the beginning speaks of is probably part of his mission... Or maybe I'm just on crack, but it seems like a really good idea to me... I think he's destined to be protector of the world or something. I think that maybe the wizard man could be the boy's watcher, and woke up to find that the baby finally was born, then went off to let other watchers know that the 'destiny child' has arrived on this world.
