Like previous seasons in Game of Thrones, the fifth season continues storylines primarily set within the fictional land of Westeros, while a few storylines are set in another continent, Essos. After the murders of King Joffrey and his grandfather Tywin Lannister, Cersei Lannister’s young, indecisive son, Tommen, rules Westeros as king. Tyrion flees to Essos, where he meets Daenerys Targaryen, who struggles to rule Slavers' Bay and regain control over her growing dragons. The Lannister family encounters new enemies, including a religious cult that Cersei foolishly empowers; they arrest her and Queen Margaery; Cersei confesses some sins and is released after a walk of atonement. Jon Snow becomes Lord Commander of the Night's Watch and serves under Stannis Baratheon, who pursues his claim to the Iron Throne by marching on the rebuilt Winterfell. Littlefinger has left Sansa Stark at Winterfell; she marries Ramsay Bolton, who rapes and imprisons her. Stannis is defeated and killed, while Sansa makes an escape with Theon. After Jon loses Night's Watchmen trying to rescue thousands of Wildlings from the White Walkers, several of his men mutiny and kill him. In Braavos, Arya Stark receives training as an assassin but disobeys her trainers, who blind her. Jaime retrieves princess Myrcella from Dorne, but she is murdered.
