Titans, old gods, demons, naaru and Elune.

So I was thinking about the Naaru and how they fit in with the titans, old gods and demons

So I came up with the following

Good vs Evil Axis are Naaru vs Demons
Order vs Chaos axis is the titans vs old gods

I don't know if it's true or not, I'm just wondering how it all fits together. Its pretty clear that the titans want to organize the universe and the old gods just want chaos, not sure what exactly the demons want, or the Naaru for that matter.

Are the naaru still chilling in outland, no plans to help out with Deathwing? And are they the only source of the "Light" or is there some greater source?

Then we add a"god" Elune. Where does she fit in? Why only 1? Is there a seperate god for each world or are we the only one that has one? Now that we consider the sun the other eye of the earthmother and it's a source of "the light" does that mean elune is the source of "Light"? or just another channeler?
