The Arryns are one of the oldest lines of Andal nobility in the Seven Kingdoms and ruled as Kings of Mountain and Vale for centuries until they bent the knee to Aegon the Conqueror. Their seat is the Eyrie, a small but unassailable castle high on a mountain. Their motto is, “As High as Honor.”
Jon Arryn, Lord of the Eyrie, Defender of the Vale, Warden of the East, and the Hand of the King has recently died as the first book begins. He fostered both Robert Baratheon and Eddard Stark at the Eyrie, and joined them and Lord Hoster Tully in rebellion against the Mad King, Aerys Targaryen, after refusing to execute his wards and marrying Lord Hoster’s youngest daughter. During the war his cousin Ser Denys Arryn, the darling of the Vale, was killed by young Lord Connington. Jon was survived by his son and heir, the sickly boy Robert Arryn, and his wife Lady Lysa of House Tully.
The arms are represented in a fashion similar to the author’s original intent, and thus strikingly unlike the arms as represented by the publisher’s artists.
