House Arryn of the Eyrie is the ruling house of the Vale. The main seat is at the Eyrie, but they have many other holdings. They alternate between the castles of the Eyrie (during spring and summer) and the Gates of the Moon (after the snow starts falling). Their sigil is a sky-blue falcon soaring against a white moon on sky-blue. Their words are "As High as Honor." The line dates back to the old Andal nation that invaded Westeros. Usually marrying other Andal nobles, House Arryn to this day has the purest line of Andal nobility. Many lesser houses are sworn to House Arryn.

The only son of Jon Arryn and his wife, Lysa Tully. He is a sickly, whiny child of six, 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 regard to him.
