Season 2 spans several months on a world where the seasons last for years at a time. The Seven Kingdoms are at war, with the King in the North, Robb Stark, fighting to win independence for his people and those of the Riverlands. Robb decides that he must win the allegiance of the fiercely independent ironborn to his cause, and sends his best friend Theon Greyjoy to treat with his father, who is hatching plans of his own. Meanwhile, Joffrey Baratheon holds the Iron Throne with the backing of the powerful House Lannister, but his uncle Renly has also claimed the throne with the support of House Tyrell, whose armies are much larger. As they struggle for the throne, Tyrion Lannister arrives in King's Landing to take matters in hand, only to face opposition from his scheming sister, Cersei, now the Queen Regent.
