Cersei Lannister is a member of House Lannister and the eldest child of Lord Tywin Lannister. She is the Queen of King Robert Baratheon, and has three children, Joffrey, Myrcella and Tommen Baratheon. She is the twin sister of Ser Jaime Lannister, and the older sister of Tyrion Lannister, whom she despises due to a prophecy that the "valonqar" would kill her. Although Tywin promised she would marry Prince Rhaegar, Cersei ended up Robert's disillusioned and resentful bride.
She is described as very beautiful, and has many aspects classic of House Lannister, including her golden hair and her green eyes. She has fair skin and a slender figure, however she starts to gain weight during the series due to her high alcohol consumption and starts to lose her beauty with age.
A Game of Thrones Edit
Cersei rides to Winterfell with Robert when he chooses to name Lord Eddard Stark as the successor to Jon Arryn as Hand of the King. She suggests that Robert not visit the Winterfell Crypts to see the resting place of Lyanna Stark but he rebuffs her. Cersei is escorted into the feast that evening by Eddard. Jon Snow sees through her smile and thinks that she is cold and angry. She later sneaks off to the abandoned tower of Winterfell with her brother Jaime. There they talk about Eddard's appointment and the threat posed by Lysa Arryn. They make love, until Cersei spots Bran Stark spying on them. Jaime tries to silence Bran by pushing him out of the window of the tower and reducing him to a comatose cripple, to Cersei's disapproval. Cersei is present at Castle Darry after the attack on Joffrey by Arya Stark and Nymeria. She insists on having one direwolf executed, and so has Lady killed. Ned, who does the killing, has the pelt sent north, however, so that Cersei can never have the direwolf's furs.
When Catelyn Stark abducts Tyrion, Cersei argues with Robert to the point where he strikes her across the face. After Lord Stark figures out the true heritage of Cersei's children, born of incest between Cersei and Jaime, he confronts Cersei and reveals that he plans to tell Robert the truth. However, Cersei has her cousin Lancel give Robert strongwine to dull his senses during a hunt, causing him to be fatally wounded by a boar. Upon Robert's death, Joffrey is King and Cersei has Eddard arrested for treason, although things turn awry when Joffrey has Eddard executed despite Cersei's wishes.
A Clash of KingsEdit
A bitter power struggle erupts between Cersei and Tyrion, when the latter is named the new Hand of the King while Tywin is absent. Cersei uses Pycelle as an agent until Tyrion finds him out and has him arrested, also sending Myrcella to Dorne. Cersei becomes livid with her little brother, and arrests a whore believed to be sleeping with Tyrion named Alayaya. She uses Alayaya as leverage over Tyrion, who proceeds to threaten Cersei. During the Battle of the Blackwater, Cersei stays in the Red Keep with the noblewomen, as well as Ser Ilyn Payne who is instructed to kill them all if the battle is lost to prevent them from becoming hostages. She also has Joffrey retreat, damaging the army's morale and almost causing the Lannisters to lose, if not for Tywin and the Tyrells.
A Storm of SwordsEdit
Cersei is furious after Tywin reveals to her that he plans to marry her off to either, as Cersei puts it, "the old squid or the crippled dog boy". On Joffrey and Margaery's wedding day, Joffrey is killed at the feast when his wine is poisoned. Cersei, distraught, immediately blames Tyrion and his wife, Sansa Stark. While Sansa escapes, Cersei has Tyrion arrested, and Tyrion demands trial by combat. Cersei names Ser Gregor Clegane as her champion, prompting Oberyn Martell to become Tyrion's. The trial by combat results in Oberyn fatally wounding Gregor, although the latter still kills Oberyn, therefore condemning Tyrion to death.
A Feast for CrowsEdit
Cersei is awoken in the middle of the night by Ser Osmund Kettleblack and Ser Boros Blount, who inform her of Tywin's death at the hands of Tyrion, who has escaped his cell. She then walks to the Tower of the Hand and witnesses her father's corpse before ordering the disposal of Shae's corpse. She later offers Jaime the position of King's Hand, but he rejects her. She decides that her uncle, Ser Kevan Lannister, is more fitting of the role than her brother. At her father's wake, and is forced into conversing with Ser Lambert Turnberry and Falyse Stokeworth, and meets Taena Merryweather, and believes that she may be useful in the future. She rejects Lord Mace Tyrell when he offers to take the position of Hand and names Lord Gyles Rosby as Master of Coin. She gives the dying Gregor Clegane to Qyburn and is rejected by Kevan when she offers him the title of the Hand.
Cersei then appears to her brother as he stands vigil over their father's corpse, asking him again to serve as the Hand, but again he rejects him. The next day she attends prayers, where Tommen is sick. She chastises him outsider the Great Sept of Baelor for looking weak in front of his lords. She is impressed when Jaime devises a plan to rid her of Mace Tyrell whilst still gaining glory for herself and Tommen. Sending Loras Tyrell to Dragonstone where he is reported to be gravely injured, Cersei establishes the Faith Militant and manipulates several men into "confessing" that they had adulterous affairs with Margaery, who had become Tommen's wife. Margaery is imprisoned, although this plot backfires on Cersei when the High Septon grows suspicious of Osney Kettleblack and tortures the truth out of him. Cersei is arrested and imprisoned, while the Small Council tries to repair the damage Cersei caused. Cersei, meanwhile, sends a letter to Jaime, but receives no answer.
A Dance with DragonsEdit
Still imprisoned by the Faith, Cersei decides to confess in order to be free. She does not confess all of her sins to the High Septon, however, and only admits to sleeping with Lancel Lannister and Osney Kettleblack. Cersei denies ever having slept with Jaime or having sired his children into the world, although the High Septon tells her that although she has confessed some sins, others must be determined in a trial. In the meantime, Cersei is allowed to return to the Red Keep until the trial, but first must perform a "walk of penance". Shorn of all her hair and stripped naked, Cersei is forced to walk through King's Landing, escorted by septas and Warrior's Sons, from the Great Sept to the Red Keep. Humiliated and hallucinating, Cersei eventually makes her way back to the Red Keep where Qyburn introduces Cersei to Ser Robert Strong, who will serve as her champion in the trial.
