HBO has released the first teaser for new Game of Thrones prequel A Knight of the Seven Kingdoms – and it may only be brief, but it gives us our best look yet at the show's two protagonists. In the seven-second clip, which you can watch above, someone asks Ser Duncan the Tall for his name. We also get a glimpse of young Egg, some impressive sword-wielding, and Dunk in battle. Per the official synopsis, the series will follow "a young, naive 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."#news #entertainment #entertainmentnews #us #tending
