House Arryn rules the Vale that shares its name, a fertile land nestled within the great range of the Mountains of the Moon. In their idyllic domain, the Arryns have often found themselves isolated from the greater events of the realm. This ended nearly fifteen years ago, though, as Lord Jon Arryn’s devotion to his former wards, Eddard Stark and Robert Baratheon, drew House Arryn directly into the events that ended the Mad King’s reign. With Jon Arryn’s recent and sudden death, rule over the Vale falls to his widow and their sickly son, Robert, the last of the Arryn line. Lady Lysa has fled to the seclusion of the Eyrie, a virtually impregnable stronghold high in the mountains and the seat of House Arryn, and threatens to shut the Bloody Gate to the rest of the Seven Kingdoms at a time when the knights of the Vale may make all the difference.
