In spite of this, Theon refused his sister's offer to return to the Iron Islands, and decided to hold Winterfell.. Following Robert Baratheon's death in 298, Robert's son Joffrey assumed the throne. He was assassinated by his brother Euron Greyjoy in 303 AC, becoming the fifth and last of the five kings to die in the war. Stannis Baratheon claimed the Iron Throne on the basis that he was the rightful heir to his late brother, King Robert I. Forming an alliance with the High Sparrow, leader of the sect, Cersei engineered his election as the new High Septon and authorized the Faith Militant, the enforcement branch of the Faith charged with defending the faithful, to rearm.  Ser Edmure Tully remains at Riverrun to guard his rear.. At the Great Sept of Baelor, Loras confessed to his crimes to the seven judging septons, one of whom includes the High Sparrow himself, and the gathered court, which includes Kevan Lannister, Mace Tyrell, and Queen Margaery. She appointed her ally, former Maester Qyburn, as the new Master of Whispers (as Varys is believed to have released Tyrion), and Lord Tyrell appointed as the new Master of Coin.

In essence, the war was a three-way battle for the Iron Throne fought alongside two independence movements. House Bolton's rule over the North was now seemingly unopposed; Sansa's escape, however, has weakened their claim. Receiving news of his father's arrest and a demand that he come to King's Landing and recognize Joffrey as King, Robb Stark mobilized the armies of the North and assembled a host of 20,000 men; due to the urgency of the situation and the vastness of the North, he could not wait for more. The army is led by none other than Littlefinger and Sansa at the behest of Robin Arryn.
