A Second "Game Of Thrones" Prequel Announced Its Cast, And It Stars Some Major Newcomers

Here's the new series' logline, courtesy of HBO: "A century before the events of Game of Thrones, two unlikely heroes wandered Westeros…a young, naïve but courageous knight, Ser Duncan the Tall, and his diminutive squire, Egg. Set in an age when the Targaryen line still holds the Iron Throne, and the memory of the last dragon has not yet passed from living memory, great destinies, powerful foes, and dangerous exploits all await these improbable and incomparable friends."
