In the books
In the novels, House Royce of Runestone is distantly related to House Stark. Eighteen-year-old Waymar is a skilled warrior, trained by his castle's master-at-arms, but is untested in battle. He is arrogant and has a tendency to underrate the experience of men longer on the Wall due to their lower birth, but is not completely stupid. He is the third and youngest son of 'Bronze' Yohn Royce.
