Fan Casting A Song of Ice and Fire

Set in a medieval fantasy world, the series primarily follows various political and supernatural threats to the Seven Kingdoms, a vast nation still recovering from a civil war that ousted the previous ruling dynasty of three centuries, the Targaryens. As the nobles busy themselves playing the game of thrones, a supernatural threat looms beyond the Wall to the far north that threatens to destroy the Seven Kingdoms and drive the continent into a permanent winter.
