House Arryn

House Arryn of the Eyrie is a Great House of Westeros that rules the mountainous region of the Vale of Arryn, from their seat of the Eyrie.

Tracing their origins back to the Andal Invasion, House Arryn ascended to rule the Vale when Artys Arryn defeated the Griffin King in the Battle of the Seven Stars, himself becoming the first King of the Mountain and the Vale. House Arryn continued to rule as Kings over their Kingdom until Aegon's Conquest, when they bent the knee to House Targaryen, becoming the Wardens of the East.

House Arryn supported Robert Baratheon in his rebellion against the Iron Throne, with Lord Jon Arryn becoming Robert's Hand of the King upon his victory. Jon Arryn's death ultimately lead to the War of the Five Kings, during which House Arryn under Jon's son, Robin Arryn, remained neutral. House Arryn went on to pledge it's forces to House Stark, before briefly seceding from the Seven Kingdoms as part of the Third Kingdom of the North. Alongside House Stark, House Arryn bent the knee to Daenerys Targaryen to secure her support during the Great War against the White Walkers, and once again extended the gesture to House Baratheon upon House Targaryen's extinction at the conclusion of the Great War.

House Arryn's sigil is a white falcon volant and a crescent moon on a blue field, and their House words are "As High as Honor".
