House Arryn

House Arryn is one of the Great Houses of Westeros. It has ruled over the Vale of Arryn for millennia, originally as the Kings of Mountain and Vale and more recently as Lords of the Vale and Wardens of the East under the Targaryen kings and King Robert Baratheon.

House Arryn's sigil is a white moon and falcon on a sky-blue field. Their motto is "As High As Honor".

In the books
In the Song of Ice and Fire novels, House Arryn is the oldest and purest line of Andal nobility. The Andals landed on the Fingers, an area of peninsulas, hills and rivers on Westeros's eastern coast, six thousand years ago and helped conquer the area of the Vale. Ser Artys Arryn is said to have founded the family after slaying the Griffin King, who had previously ruled the region for the First Men, on the shoulder of the Giant's Lance where the Arryns later built the Eyrie.

During the summer they rule over the Vale from the Eyrie, but during the winter they descend to the Gates of the Moon, a castle at the foot of the mountain. The Gates of the Moon appear to be missing from the TV version.

A notable change from the books is that Jon Arryn and Lysa Tully's son is now called 'Robin', whilst in the books he is 'Robert'. This change was made to prevent confusion with Robert Baratheon or Robb Stark. George R.R. Martin approved this change, noting that Robert Arryn's nickname in the books, 'Sweetrobin', remains intact.
