I am believed to be the oldest son and heir of King Robert Baratheon and Queen Cersei Lannister, both of whom entered into a political marriage alliance after Robert took the throne by force from the Mad King Aerys II Targaryen. In reality, my father is Jaime Lannister, the queen's brother and the Lord Commander of the Kingsguard. I have a younger sister, Myrcella, and a younger brother, Tommen , both whom are also the product of Jaime and Cersei's incest. Our sole biological grandparents, Tywin and Joanna Lannister, were also apparently first cousins.
