Game of Thrones Season 3 spans several months on a world where the seasons can last for years at  a time. Autumn has fallen across the world, with winter not far behind.  The people should be preparing for years of snow and ice, but the Seven  Kingdoms of Westeros instead remain gripped by civil war. Would-be king  Renly Baratheon has been assassinated, altering the alliances in the  war. The cruel boy-king Joffrey Baratheon has won a great victory by  securing an alliance with House Tyrell, with his supporters defeating  his uncle Stannis in an epic battle. Joffrey now commands the largest  armies in the realm and his triumph appears inevitable.

King  Robb Stark remains in the field, however his homeland, the North, is  partially under ironborn occupation. Robb needs to decide on a course of  action to win an overall victory. He must also win back the allegiance  of House Frey, whom he has offended by breaking his marriage pact to  them. King Robb has won every battle he has fought, but as with old King  Robert, the Starks will have to see if good soldiers make good kings.

Stannis Baratheon may be defeated and most of his army destroyed or  scattered, but he is not out of the fight yet. Having retreated to his  headquarters on Dragonstone island with his handful of surviving  soldiers, Stannis' status as the last legitimate heir to his older  brother Robert still casts a shadow over Joffrey's claim to the throne.  With the priestess Melisandre at his side, Stannis can still influence  the course of the war by striking where least expected.

The  lives of many others still hang in the balance. Bran Stark and his  protectors must cross the frozen wastelands of the North to reach the  Wall, whilst Arya must brave the war-torn Riverlands in search of her  mother and brother. Brienne also has the thankless task of taking the  captive Jaime Lannister home across hundreds of miles of battlefields  and carnage. Theon Greyjoy must face the consequences of his actions at  Winterfell. And in King's Landing both Tyrion Lannister and Sansa Stark  must brave the currents of a much more dangerous court in order to  survive.

On the eastern continent, Daenerys Targaryen has fled  the political viper-pit of Qarth. Her dragons are growing and her fame  is spreading, but to take the Iron Throne she will need supporters and  an army. Both may be found in the corrupt cities of Slaver's Bay... for a  price.

Beyond the Wall, the White Walkers are on the move,  threatening both the Seven Kingdoms and the lands of the Free Folk.  While the Night's Watch faces the threat of the White Walkers in the  field, Jon Snow must infiltrate the wildling army of Mance Rayder and  discover the King-Beyond-the-Wall's plans.
