Robert Arryn is the only son of Jon Arryn and his wife, Lysa Tully. He is a sickly, whiny child, now Lord of the Eyrie and Defender of the Vale. Robert is afflicted with a disease that causes frequent seizures. His mother, Lady Lysa, rules the Vale as regent in his name. He is intellectually and physically stunted, and is not even weaned from his mother's breast.

Upon the death of Robert's mother, Petyr Baelish assumed the position of Lord Protector of the Vale, and claimed the rule of the Vale and the guardianship of Lord Robert through his brief marriage to Lady Lysa. Several of the more prominent nobles of the Vale signed a declaration to oust Petyr from the Eyrie and assume the rearing and training of Robert Arryn, calling themselves the 'Lords Declarant.' Robert has become even more emotional and unstable after his mother's death, and has become highly attached to his cousin, Sansa Stark, in her guise of Alayne Stone, who has taken on a surrogate maternal role with regards to him.

On the TV showEdit

On the Game of Thrones TV adaptation of the books, Robert Arryn is renamed Robin Arryn, to avoid confusion with Robert Baratheon and Robb Stark. This change was suggested by George R.R. Martin, as it allows the writers to retain the character's nickname of "Sweetrobin". On the TV show he is played by Lino Facioli.
