The reason for the Void Elves appearance is because of Nether-Prince Durzaan.
He trapped Umbric and his followers, then tried to perform a ritual in which he would transform them into beings of the Void.
But the ritual was interrupted halfway through by Alleria Windrunner and the player character.
Hence the blue Void Elves.
Their creation was a fluke, a mistake.
And they are few. Less than a hundred most likely.
So it was a plothole regarding how Void Elves would create more of themselves.
They took combat casualties like everyone else, as you can see when you’re fighting invasions as a Horde character, you’re killing Void Elves left and right.
And we know for a fact that studying the Void conventionally (without having a Void Ethereal trap and try to transform you) does not alter your appearance.
Alleria studied the Void under Locus-Walker long before she consumed a darkened Naaru.
So now these “normal skinned” Void Elves plug this plothole, as they are the “2nd generation”, the ones who came after to the Telogrus Rift and studied the Void under Alleria, Locus-Walker and Umbric and his “1st generation”.
Very unlikely, as that would make the existence of the “Void form” racial redundant.
Would you become even Voidier whenever that procced then?
I disagree that there needs to exist a difference.
But the hair colors don’t matter much to me. I wouldn’t use the blondes, browns or reds available to the Blood Elves anyway.
One can argue that extended stay in the Telogrus Rift, studying the Void alters you to a lesser extent.
That only your eyes and hair change, not your entire body.
Eyes because of the Void Energies you now rely on, and the hair because of the passive “Void Radiation” or whatever you wanna call it.
Draining the “vibrant colors” the Blood/High Elves have.
I’d like to see a jet-black hair color though and a snow-white one, they are cool and fit the Void Elf theme.
Black because “Void”.
And white because of the “draining nature” of the Void. Maybe draining color from your hair during your “studies”.
Blood Elves don’t have the black and white I’m talking about. Their black is more a lighter shade of “blue-black” while their white is just “platinum-blonde”.
That Alleria keeps her “shiny blonde” could be explained with her not spending as much time in the Telogrus Rift as the new students.
Who knows where she was when he studied.
It’s weak, but it works.
