Seven Kingdoms: Seowyn's Crossing
Harbryn Thonwyr is the elder son of Hadyn Thonwyr and Eleanor Kassryx, the current King and Queen of Summerlund. He has been publicly named Crown Prince of Summerlund and Duke of Estshar. He is the older brother of Prince Ullyn and Princess Shairi.
Harbryn is very much his father’s son. Keenly aware of his duty to someday be King of Summerlund, he has studied history, tactics, warfare, and personal combat. He is a serious and sober young man who seems much older than his years. He has the raven black hair common among House Thonwyr, and has grown a small goatee to try and look older.
