|Died||In 257 AC or 258 AC, King's Landing|
About 257 AC Kaeth was made Grand Maester at the age of eighty and sent to serve the court of King Aegon V Targaryen in King's Landing. He died within a year of his appointment and was succeeded by Grand Maester Ellendor.
Grand Maester Kaeth wrote the well-regarded work Lives of Four Kings, a detailed history of the reigns of Daeron I, Baelor I, Aegon IV, and Daeron II. Kaeth scants Viserys II terribly, however, as his short reign as king came after Baelor's.
