Petyr Baelish
The Eyrie was held by Lord Jon Arryn, who fostered Ned Stark and Robert Baratheon prior to Robert's Rebellion (also known as the War of the Usurper). After the war, Lord Arryn served as King Robert I Baratheon's Hand of the King (prime minister). After Lord Arryn was assassinated, his wife, Lady Lysa Arryn, took her sickly child, Robin, and fled to the Eyrie. Lysa refused to align herself with any of the claimants during the War of the Five Kings, but eventually pretends to a possible alliance with House Lannister after Lord Petyr Baelish agrees to marry her. Later Baelish kills Lysa after she attempts to murder her niece, Sansa Stark. As of "Feast for Crows", Baelish rules in the Eyrie as the Lord Protector and Regent for the sickly, epileptic Lord Robert "Robin" Arryn, and plans for Sansa to marry Harold Harding, who will become heir to the Eyrie and the Vale in the event of young Robin Arryn's death.
