Gerold the Mefisto

Gerold was present when King Aerys II Targaryen burned Lord Rickard Stark alive in the throne room, and while Brandon Stark strangled himself to death. After the two Starks died, Gerold took Ser Jaime Lannister aside and reminded him they were sworn to defend the king, not to judge him.

During the ensuing rebellion, after the Battle of the Bells, Gerold was sent to find Prince Rhaegar. While Rhaegar eventually returned to King's Landing, Gerold did not. He was next seen at the Tower of Joy in the Red Mountains of Dorne, with two of his sworn brothers, Ser Arthur Dayne and Ser Oswell Whent, both of whom had been with Rhaegar when he disappeared originally. Here, they were guarding Lyanna Stark.

The three Kingsguard were eventually found at the tower by Lyanna's brother, Lord Eddard Stark of Winterfell, and six of Eddard's companions. After a short conversation with Eddard, during which the three knights refused several opportunities to leave unharmed, a battle ensued in which Gerold died. Stones from the tower were used to build his cairn upon a nearby ridge.
