The show, A Knight of the Seven Kingdoms, is an adaptation of The Hedge Knight, a novella by George R.R. Martin. There will be six episodes in this initial season.

Here’s the show’s synopsis, from Warner Bros. Discovery:

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.
