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.
Along with Lords Beesbury and Redwyne, Lord Costayne accompanied the High Septon to King's Landing for the coronation and wedding of King Aegon III Targaryen. A Costayne girl was among the names suggested by Samantha Tarly as possible brides for the king. Ser Leo Costayne invaded the Iron Islands after the death of Lord Dalton Greyjoy, but was slain at Great Wyk.
Lord Costayne fought for the Blackfyres during the First Blackfyre Rebellion. The Costayne force that participated in the Battle of the Redgrass Field fought on the left of Daemon Blackfyre's host. His son and successor was present at Whitewalls during the Second Blackfyre Rebellion. Ser Tommen Costayne participated in the tourney at Ashford Meadow in 209 AC. The son of the Blackfyre-supporting Lord Costayne participated in Lord Ambrose Butterwell's wedding festivities. This 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's spies. He was promptly killed by a man in service to Lord Costayne.
