Cersei Lannister

"Everyone who isn't us is an enemy."

- Queen Cersei Lannister

Cersei Lannister, rarely called Cersei Baratheon, is a major character in Game of Thrones. She is played by starring cast member Lena Headey and débuts in the first episode of the first season.

Cersei is the Queen Dowager of the Seven Kingdoms. She is the only daughter of Lord Tywin Lannister, the twin sister of Ser Jaime Lannister and the elder sister of Tyrion Lannister. She is the wife of King Robert Baratheon, a political marriage Robert agreed to in thanks for her father's late switching of sides in the civil war which brought Robert to power. She has three children: Joffrey, Myrcella and Tommen. She claims that they are Robert's although it is later revealed that they are illegitimate and a result of her incestuous relationship with her brother Jaime, something not in common knowledge. She is noted for her great beauty.

Season 1
In King's Landing, Queen Cersei watches the silent sisters preparing the body of Lord Jon Arryn, the Hand of the King, for burial. She and her twin brother, Jaime, discuss the situation and wonder if Jon told anyone else about what he had discovered. Jaime tells her not to worry, since if the King knew the truth they'd be dead already. She suggests that Jaime could be the next Hand, but Jaime refuses, citing the position as too responsible and too dangerous.



King Robert decides to travel to Winterfell and ask his best friend, Lord Eddard Stark, to become the new Hand, as well as proposing that his son Joffrey marry Eddard's eldest daughter, Sansa. Cersei, Jaime, and many others of the court accompany him. The royal party arrives at the Stark castle of Winterfell and Lord Eddard presents his household to Robert and Cersei. After initial greetings, Robert demands to see the crypts and pay his respects to his former betrothed, Lyanna Stark, stoking Cersei's impatience. After Robert and Eddard depart, Cersei sends Jaime to find their younger brother Tyrion, who has become distracted at the local brothel.

That evening a great feast is held and Cersei and Catelyn Stark exchange cordial words. Cersei seems impressed by Sansa, thinking that she will be a great hit at court. The next morning Eddard and Robert go hunting, leaving the castle largely empty. Cersei and Jaime liaise in derelict tower. Bran Stark climbs the tower and finds them engaged in sexual intercourse. He is caught watching by Cersei, and Jaime grabs him. He asks how old Bran is. When Bran replies "ten", Jaime sighs and pushes him out of the window, musing "the things I do for love."



The next day, at breakfast, Tyrion tells his family that Bran is expected to live and notes his sibling's guarded reactions to the news. Cersei visits Catelyn who is sitting vigil for Bran. Cersei tells Catelyn that her first child, a beautiful, black-haired boy, died because of a fever. She and Robert were grief-stricken and her prayers and tears were for naught. She offers to pray for Bran's survival, hoping that this time the gods will listen. The royal party sets out for King's Landing, now joined by Eddard, Sansa and Arya. However, a minor fracas between Arya's direwolf and Joffrey on the Kingsroad escalates into an argument between Cersei and Eddard. Robert defuses the situation by agreeing that he and Eddard will attend to their own discipline. Cersei insists that the direwolf must be killed. When Nymeria cannot be found (Arya having driven her off to protect her), Cersei has Sansa's wolf, Lady, killed instead. Eddard, furious, attends to the matter himself.

Arriving back at court, Cersei talks to Joffrey about the incident on the Kingsroad. She tells him that when he is king, the truth will be whatever he decides it will be. Joffrey tells her that he thinks there will be trouble with the Starks, and that when he is king he'll double their taxes, force them to contribute to a standing army and, if they should object, he'd crush them. Cersei elucidates that the North is too vast and wild to be militarily conquered by outsiders. She cautions Joffrey that he will need to be cleverer as king. She also advises him to be kind to Sansa to avoid storing up trouble for later, and concludes that "anyone who isn't us is an enemy." A raven arrives in King's Landing with news of Bran's recovery. Cersei fears he will expose their secret, but Jaime comforts her.

Cersei and Robert share a drink and discuss the threat from the Dothraki now that Daenerys Targaryen is married and pregnant. Cersei also tells Robert that at the start of their marriage she truly loved him. He says he knows, but could never love her back due to his feelings for Lyanna Stark.

Cersei and King Robert visit Eddard as he recovers from wounds sustained fighting Jaime and his guards. Cersei is furious with Eddard for having her brother Tyrion arrested and for fighting with Jaime, but Eddard is unrepentant.



Eddard confronts Cersei and tells her he knows her children are fathered by Jaime. She does not deny it, instead saying that she and her brother belong together, always. Cersei says she did love Robert, at the start, but on their wedding night he uttered Lyanna's name, which soured their relationship afterwards. Eddard advises her to leave King's Landing before Robert returns from a hunt, as he will then tell Robert the truth. Cersei instead warns him that "In the game of thrones, you win or you die."

Robert is mortally wounded on the hunt. Cersei is concerned that Eddard will tell Robert the truth, but Eddard chooses to spare his friend further pain. Robert names Eddard Protector of the Realm and regent. Upon Robert's death Cersei quickly installs Joffrey on the throne. Eddard tries to reveal the truth with the help of Petyr 'Littlefinger' Baelish, but Baelish betrays him and sides with Cersei. Eddard is arrested and imprisoned, whilst his guards are killed.

Cersei persuades Sansa to write a letter asking her brother Robb to bend the knee to Joffrey in return for her father's life. Sansa agrees, but the plan backfires, as the letter merely encourages Robb to raise an army and march into the Riverlands to confront the Lannister armies directly. In open court, Cersei encourages Sansa to make a new plea to Joffrey for her father's life. Joffrey agrees to spare him and let him join the Night's Watch, if Eddard recants the claims he has made about Joffrey not being the true king. Sansa is sure he will. Cersei is present at the Sept of Baelor when Eddard Stark 'confesses' his crimes, as per their arrangement brokered by Sansa and Varys. She appears to be genuinely shocked when Joffrey ignores the arrangement and demands Eddard's decapitation. The order is carried out by Ser Ilyn Payne, the royal executioner.

War erupts between the Lannister and Stark armies in the Riverlands and Cersei attempts to secure her son's hold on the Iron Throne. She takes a new lover, her cousin Lancel who was King Robert's squire and gave him the wine that made him too drunk to slay the boar that killed him. She also receives a letter informing her of Jaime's capture by Robb Stark.

In the books
In the Song of Ice and Fire novels, Cersei is a beautiful but also somewhat cold woman who does not get on with her husband, whom she considers to be a fat oaf. However, she dotes on and loves her three children. She is not politically skilled, and frustrated that her options for power are limited by her gender. Cersei is close to her brother Jaime, but is cowed by her father and despises Tyrion, whom she blames for killing her mother Joanna, who died in childbirth.
