The War of the Five Kings has reached its tipping point. Stannis Baratheon marches on King's Landing by land and by sea, sending his powerful navy up the Blackwater Rush to seal off any escape. Tywin Lannister moves south with all speed, leaving the north to House Stark and House Greyjoy, but his mighty armies will never arrive before the city is besieged. In the end, the man who sits the Iron Throne at the end of the battle may be determined by nothing more than the ingenuity of Tyrion Lannister's defenses.
