In the books
In the Song of Ice and Fire novels, Ser Stevron resembles a weasel, like his father. He has grey eyes. A man in his sixties, Stevron's appearance shows his age. Walder has groomed him for lordship of the house, though Walder often jokes that Stevron has been waiting for him to die for forty years. Through his father, Stevron has learned to place great importance on the family. Stevron, unlike his father is amiable and reasonable. In the book Stevron rides out to parley with the Stark army on their arrival.
