In the aftermath of the War of Five Kings, "Sparrows", religious folk seeking the protection of King Tommen Baratheon following a spate of atrocities committed against members of the Faith of the Seven, converge on King's Landing. When the Most Devout convene to elect the new High Septon, the sparrows hijack the selection process and force the selection of their leader, who is dubbed the "High Sparrow" by the royal fool Moon Boy. Cersei Lannister permits the High Sparrow to re-establish the Faith Militant, the military arm of the Faith, in return for the Faith forgiving the Crown's debt to it and blessing Tommen. The Faith Militant subsequently arrest Margaery Tyrell and several of her cousins when Cersei's confidante Osney Kettleblack claims to having slept with the women. The High Sparrow is suspicious of Osney's testimony (not unfairly, as Osney had been persuaded to perjure Margaery by Cersei to shore up her own power) and has him tortured until he confesses not only that Cersei arranged for his false testimony, but also that she ordered him to kill the previous High Septon. When Cersei visits the Great Sept of Baelor, the High Sparrow has her arrested and imprisoned.
