BarristanSelmy

Lord Commander of the Kingsguard until King Joffrey ousted him, Ser Barristan left King's Landing in anger and has not been seen since. Also known as Barristan the Bold, his commitment to his oath was unyielding and under the former king, Aerys, he never wavered in his promise to protect the Targaryens. After taking the throne, Robert Baratheon pardoned him and promoted him to lead the Kingsguard.
