Great Forces

First, the thought occurs to me that I really have this image in my head of two 'Gods' Destiny and Prophesy fighting this war or game over a world with competing and yet matching agendas. But there has to be a bad guy 'force' for it to really be high Fantasy. Is it Destiny or Prophesy? The other thought that occurs to me, is (and I still have work to do on this part) if they emerge 'from chaos' as described by many mythos (particularly Greek and Norse), what of their failed experiments before they get to the story world itself? After all, while it might be nice to think that such powerful beings could just spontaneously think of things like Cheese and Bricks and Marmosets all at once, I imagine a more logical expression is things like sentience, emotions, and communication, so getting around to actually making a world and such would take a whole lot of time. Time, of course, in such circumstances, being entirely relative.
