Game Of Thrones: House Arryn, Explained

King Robert I Baratheon’s First Hand, Lord Jon Arryn’s sudden death ignites a feud between the Starks and the Lannisters. This hostility and rift between the two Great Houses of the Seven Kingdoms is sparked by the letter that Jon’s widow, Lysa Arryn sends North to her sister, Catelyn Stark. She claims that the Lannisters have a hand in Jon’s death. Around the same time, Queen Cersei Lannister and her brother, Jaime’s cryptic remarks in Game of Thrones season 1, episode 1 “Winter Is Coming” about the nature of Jon’s death indicate there’s more to it than meets the eye.
