An Affair for the Loyal
The King is Dead – LONG LIVE THE KING!
Robert Baratheon, First of His Name, King of the Andals and the First Men, Lord of the Seven Kingdoms is dead. His son Joffery Baratheon has ascended the Iron Throne, with his Queen Mother Cersei Lannister ruling as the Queen Regent until Joffery comes of age. These are the halcyon days for House Lannister, Lord Tywin is battling the rebel “King in the North” in the Riverlands and this would be “King’s” father, the treasonous Eddard Stark has been put to death by the King’s Justice after confessing his crimes.
You are a member of a noble house sworn to the Lannisters. You hold domains in the prosperous West and have sworn oaths of loyalty to Lord Tywin. You have not, on the other-hand, sworn such oaths to your peers. As the Queen Regent once eloquently said “Our enemy is anyone but us.”
