From A Wiki of Ice and Fire
Fair Isle is an island in the Sunset Sea off the coast of the Westerlands. It is controlled by House Farman, whose seat Faircastle sits on it. The Crag is northeast of Fair Isle, while a peninsula containing Kayce and Feastfires is south of the island.
During the reign of Aerys I Targaryen, the ironborn raided Fair Isle, making off with half its worth.
The Battle of Fair Isle took place off the coast during the Greyjoy Rebellion.
