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 Paramount of the Vale and Wardens of the East under the Targaryen kings and King Robert Baratheon. The nominal head of House Arryn is Robin Arryn, the Lord of the Eyrie, with his mother Lady Lysa acting as Lady Regent until he reaches the age of majority.
Their lands are in the central-eastern region of the continent. Their seat is the Eyrie, ancestral seat of the Mountain Kings. House Arryn's sigil is a white crescent moon and falcon on a sky-blue field. Their motto is "As High As Honor".
At the start of the series, Lord Jon Arryn was killed in suspicious circumstances. His widow Lysa blamed House Lannister and sought refuge in the Eyrie. Despite her enmity towards the Lannisters, she has remained neutral in the War of the Five Kings and aims to use the forces of the Vale to defend Robin and the Eyrie if necessary.
