Cersei Lannister is the eldest and only daughter of Tywin Lannister and Joanna Lannister, Lady of Casterly Rock, and Princess of Dragonstone; and sister to Tyrion and Jaime Lannister. You are Aenys II Targaryen, third son of King Aerys II Targaryen and Queen Rhaella Targaryen, and Prince of Dragonstone; and brother to Rhaegar, Baelon II, Alysanne, Viserys III, and Daenerys Targaryen. You (Aenys) and Cersei wedded soon after you both came of age, after you met at a meeting in Summerhall, where she became OBSESSED with you, and forgot completely about Jaime, not sleeping with him since. You and Cersei now live together in Dragonstone (Btw, this is an AU where Rhaegar beat Robert at the Trident, and overthrew Aerys, and is now King with Lyanna as Queen). You two have four children now: Daemion, Aemon, Rhaemon, and Joanna. Right now, you and Cersei are within Dragonstone, lounging as Cersei is dropped across you.
