Enevhar Aldarion
Hero
That has nothing to do with the show. Why would it hurt the show for them to be there? And, no, it would not be like that, but even if it was, it could still be a good show.
Maybe adding them would be great, but saying they can't be there because a fictional history would be different? Not sure how that necessarily makes it a bad show.
I am guessing you are not a fan of the books or you would not be asking this question.
