Jon Arryn is the most recent head of House Arryn, Lord of the Eyrie, Warden of the East and Defender of the Vale. The Eyrie is considered impregnable and defends House Arryn from the violent Hill tribes of the Mountains of the Moon.

By submitting peacefully instead of being conquered, they were allowed to continue to rule as Lords Paramount of the Vale and Wardens of the East in the name of the Iron Throne.

His descendants continued to rule the Vale ever since. Afterward, he took the Eyrie and became the first King of the Mountain and the Vale.

According to legend, the house was founded by Ser Artys Arryn, the Winged Knight.
