The new one-hour drama would be based on the “Tales of Dunk and Egg” series of novellas by George R. R. Martin.

Comprised of three books, 1998’s The Hedge Knight, 2003’s The Sworn Sword and 2010’s The Mystery Knight, the series follows the adventures of “Dunk”, Ser Duncan the Tall, and “Egg”, a young Eagon Targaryen, and is set 90 years prior to the events of “Game of Thrones”.

All three books were published together in a single volume in 2015, titled A Knight of the Seven Kingdoms.
