Coup at the Iron Throne
Eddard Stark attempts to install Stannis Baratheon as king, but Cersei Lannister, with the support of the City Watch and Littlefinger, stages a coup. Eddard is betrayed by Littlefinger and arrested for treason. His household guard is slaughtered, and he is thrown into the dungeons. This event marks the fall of House Stark in King's Landing and the beginning of the War of the Five Kings.
