A nobleman's illegitimate son discovers his true parentage amidst a brutal struggle for control of the Iron Throne, as noble houses across a vast fantasy kingdom wage war, form alliances, and betray one another in pursuit of power. Meanwhile, a exiled queen builds her forces across the sea, determined to reclaim the throne she believes is her birthright, whilst an ancient supernatural threat gathers beyond a great northern wall. The series, which spans eight seasons, is renowned for its willingness to kill off major characters and for subverting the conventions of epic fantasy storytelling.
