There was this thing about Azeroth having two moons, but one vanishing with BC. Then when did this happen? It’s sadly impossible to get both onto one screen, as they stay no matter how you move, but the screenshots are from the same moment. I don’t know what to make of this.
I can’t remember having seen it before the last patch, but then again I could be wrong and totally late with this.
The Blue Child returned to Azeroth’s sky during patch 5.0.4! They said that the White Lady send the Blue Child on a mission to scout for the Burning Legion and to only return when they are coming. (dun dun DUUUUUN!) WoWInsider
That is both very interesting and intensely disturbing.
