Following this quote from a recent interview, we can say that Void elves have been biologically altered at a cellular level by the Void, thus if they died they would not actually go to the Shadowlands with the other mortals, but to the Void. This phenomenon has been compared by Blizzard to the demons returning to the Nether upon dying, and as we all know the demons were not mortal creatures and actually looked down on mortals. The same thing applies to the Old Gods and their faceless minions.So that same rule that we established in Legion for a being of an influence goes back if it’s killed in the mortal realm or some other realm, it goes back to it’s home realm, it’s home plane. That’s true for demons and that’s true for other forces as well.
Those cases are the exception rather than the rule. So if you destroyed a being of the Light, it would go back to the realm of Light and to really destroy it, you would have to go to the realm of Light and destroy it there.
So then is it fair to assume that the void elves have been elevated to the status of immortality? And by that I don't mean a fake immortality like the one the night elves had, which was basically just eternal youth (indeed death still sent them to the Shadowlands with the other mortal masses). By immortality, I mean the supreme immortality that the demons have, that the Old Gods have, that the naaru have, and that every other cosmic-based being has. This must be especially true for Alleria Windrunner, a special void elf who actually merged with the essence of a dark naaru, thus ascending to a higher form.
So then if the game were to reflect the lore more accurately, would my void elf character return to the Void upon dying, instead of going to the ghost version of Azeroth that every other race goes through?
