They've already confirmed that scars are in as a base character creation choice, but if you really are the Dragonborn and supposed to save the world, you'll probably end up fighting a lot, and it'd be a shame for there to be nothing to remember your fights by xD. Maybe you could even have an option to get something like "plastic surgery," where you visit a mage that "resets" your scars?
I may be barking at the moon here, but I think if it doesn't take too much time to implement, it would be a great addition that only makes it more immersive.
any thoughts?
