Lord Walter was among the handful of Dornish lords that joined the host of the first Vulture King during the reign of King Aenys I Targaryen in 37 AC. Walter had heeded the Vulture King's call for all "true" Dornishmen to join his cause against the Seven Kingdoms, despite Princess Deria Martell denouncing the outlaw "king". As the Vulture King's host grew in size, he divided his strength and marched against Nightsong and Horn Hill, while Walter commanded the other half to besiege Stonehelm, the seat of House Swann.
Lord Orys Baratheon rode forth from Storm's End and smashed Walter's host beneath the walls of Stonehelm. Walter was injured and captured during the battle and brought before Orys. Walter's father had chopped off Orys's sword hand during the First Dornish War and, in retaliation, Orys chopped off Walter's sword hand, then his other hand, followed by both feet. Orys deemed this "usury".
Your father took my hand. I claim yours as repayment.—Orys Baratheon to Walter Wyl
