Ser Ilyn Payne is a knight and member of House Payne, the royal executioner of King's Landing, and a loyal servant of House Lannister. Ser Ilyn went with Lord Tywin to King's Landing when he became the King's Hand to King Aerys II as the commander of his household guard: Ser Ilyn would then later have his tongue cut out by Aerys II for claiming that Tywin was the true king of Westeros. After Robert Baratheon took the throne, he became the King's Justice, and was personally responsible for having executed Eddard Stark. A year later, during the Battle of the Blackwater, Queen Cersei has him remain by her side: should the city fall, he will kill her and all the women to avoid them getting raped. In the show, Ser Ilyn remains at King's Landing, but does not appear. In the books, Ser Ilyn is the one to teach Ser Jaime how to fight with his left hand, and also accompanies him to the siege of Riverrun.
