The story features many iconic characters that viewers grew to love or hate. Important figures include Jon Snow, a brave warrior from the cold North; Daenerys Targaryen, a exiled princess known as the "Mother of Dragons"; and Tyrion Lannister, a clever nobleman who uses his intelligence to survive. Beyond the human fights for political power, the kingdoms face a far greater danger from the North: a terrifying army of ice creatures known as White Walkers, who threaten to destroy all human life beyond the giant Great Wall.
