What happened to them? I know they had a great battle and from that battle the Daedra and Aedra came into existence. But what happened after that? Is Padomay really dead? and where is Anu? is he still out there?

Certain myths personalise these two forces so as to appear less impersonal to us, but this leads to misunderstandings like the above. They are stasis and change, and they did not really go anywhere. Their existence is ultimately meaningless outside of the thing which came from their interplay; i.e. the universe. And, as metaphysical forces, they still pervade and define that universe, down to its petty dualities and conflicts.
