We now know that the titans are born as world souls - a living planet.
Now there are also our light buddies- the Naaru... shining like thousand suns, referenced as star ("the dark star"),
collapse into a black hole (void god), release enormous amount of energy in death (supernova, revival of the sunwell),
and their whole atmosphere is about space and stars and scapegoats... and I'm sure there is more.
are they "sun soul"?
anyway, if true, more sources of holy magic can be directly connected to the Naaru (like An'she (being a sun), the sunwell for blood-elves, the light of the draenei, and... Elune- as the moon in a mere reflection of the sun).
