I thought Void Elves were originally Blood Elves that were kicked out of Blood Elf society for messing around with Void magic? I think that is the result of their default hair style. I cannot imagine Blood Elves having that kind of hair since if they messed with Void magic they would be exiled, “becoming” Void Elves.
Perhaps ask for antlers first since they might be able to be conjured with ordinary magic?
