Okay, so... Tauren Paladins get their "Light" from the sun.
So, the sun is their source of "Light".
When a sun dies, it can create a black hole.
A black hole is a great 'darkness' (obviously a little more than that, but) that destroys everything.
The Naaru are connected to the 'Light'.
When they die they create a Void Lord, a dark creature that destroys everything.
Ya see where i'm getting at here?!
tl;dr The sun is a Naaru.
P.S. I dunno what that means for Mu'sha. Guess we'll just go with Space Elf Woman.
(Note: This is not to be taken seriously, obviously this was just a silly connection I noticed that you all should think about because it would be fun! :P)
