Lord Owen Costayne of Three Towers declared for Princess Rhaenyra Targaryen during the Dance of the Dragons, going against his Hightower overlords. He was mortally wounded by Ser Jon Roxton's Valyrian steel black blade, Orphan-Maker, during the Battle on the Honeywine.
Lord Costayne fought for the Blackfyres during the Blackfyre Rebellion. The Costayne force that participated in the Battle of the Redgrass Field fought on the left of Daemon Blackfyre's host. After becoming Lord of Three Towers in his own right, his son participated in Lord Ambrose Butterwell's wedding festivities. The new Lord Costayne was married to the daughter of Lord Ambrose by his first wife. Lord Costayne was defeated at the Whitewalls Tourney by Ser Glendon Flowers. After the Second Blackfyre Rebellion was put down, a man in service to Lord Vyrwel claimed to have been one of Brynden Rivers' spies. He was promptly killed by a man in service to Lord Costayne.
