@Nekyn Alb I'm not saying that the Lore wouldn't allow Dragonborns, just that there needed to be a good reason for us to be able to use the Voice.

Just like how Bethesda can come up with some good way to make us immune to the diseases or something, or maybe Umbriel's Daedric magic changed Black Marsh, there are countless possibilities.
