Jaime Lannister, known as the Kingslayer, is the second child and firstborn son of Lord Tywin Lannister of Casterly Rock and his wife, Lady Joanna. Raised to the Kingsguard of the Mad King, Aerys II Targaryen, at the age of fifteen, Jaime was the youngest member of the order in history. He earned his nickname when he slew King Aerys at the end of Robert's Rebellion. For most of their lives, Jaime has participated in an incestuous relationship with his twin sister, Cersei. He has fathered three children by her: Joffrey, Myrcella, and Tommen, though the realm believes their father to be Cersei's husband, King Robert I Baratheon.
After a confrontation with Eddard Stark, Jaime flees King's Landing for Casterly Rock. He invades the riverlands at the head of a Lannister army. He gains victories at the Golden Tooth and Riverrun, but is then taken unaware by Robb Stark, who captures Jaime in the Whispering Wood. He is imprisoned in Riverrun, where he remains a captive for a year. In A Storm of Swords Jaime becomes a POV character. Read more.
