Across the Seven Kingdoms, the Great Houses of Westeros struggle to control the Iron Throne. As the influential House Baratheon, honorable House Stark, treacherous House Lannister, and fierce House Targraryen vie in a life-or-death struggle for the future of the realm, dark and supernatural forces amass outside the kingdom’s defensive wall. Winter is coming. Do you have what it takes to emerge victorious in the only game that matters, A Game of Thrones?
