  ==== Season 6 ====
  Cersei remains in the Red Keep, confined to her chambers and stripped of her authority. Although she accepts Tommen's apology for his lack of action in her arrest and walk of atonement, she remains looked down upon by other members of the court. Cersei learns from Tommen that the High Sparrow plans to have Margaery do a walk of atonement before Cersei's trial and conspires with the Small Council to have the Tyrell army march on the Sept of Baelor to secure Margaery's and Loras' release. Their plan backfires when it is revealed that Margaery has joined the Faith of the Seven and has convinced Tommen to merge the Faith and the Crown. Despite being stripped of her allies, Cersei opts to remain in King's Landing, having named Ser Gregor as her champion in her trial by combat. However, Tommen announces that trial by combat has been abolished and replaced by trial by the Seven. Cersei arranges for a cache of wildfire to be detonated beneath the Sept during Loras' trial, which kills the High Sparrow, Margaery, Loras, and the rest of the Small Council. As a result of Cersei's actions, Tommen commits suicide. In the power vacuum following Tommen's death, Cersei claims the Iron Throne as the first ever Queen Regnant of the Seven Kingdoms.
