Danuser is head of the story and I asked that question after Shadow Rising was revealed. I’d say that trump your understanding.
We have this thing call “suspension of disbelief”. If she doesnt exist, she isnt a void elf either because void elves are not real in the first place. Dont dare fight me with that logic.
I didnt demand anything , this is the reponse given to me by a story dev himself. It is just as canon as anything else short of an outright “Danuser was wrong/this is the actual lore”.
