‘Game of Thrones’ Prequel Series ‘A Knight of the Seven Kingdoms: The Hedge Knight’ Ordered at HBO

The Game of Thrones prequel based on George R.R. Martins Dunk and Egg books is officially moving forward at HBO.

The announcement was made during Warner Bros. Discovery presentation to press and investors on April 12, in which it was announced that the combined HBO Max and Discovery+ streaming service will be known simply as Max. It also comes a little over two years after Variety exclusively reported that the series was in development.

The show is based on the series of fantasy novellas by Martin, which follow the adventures of Ser Duncan the Tall (Dunk) and a young Aegon V Targaryen (Egg) 90 years prior to the events of A Song of Ice and Fire.

The series is currently titled A Knight of the Seven Kingdoms: The Hedge Knight. The official logline states, A century before the events of Game of Thrones, two unlikely heroes wandered Westeros a young, nave 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.

Martin will serve as writer and executive producer, as will Ira Parker, who was a co-executive producer on Season 1 of House of the Dragon. Game of Thrones and House of the Dragon vets Ryan Condal and Vince Gerardis will serve as executive producers.

Martin has published three novellas in the Tales of Dunk and Egg series to date: The Hedge Knight in 1998, The Sworn Sword in 2003 and The Mystery Knight in 2010. The three novellas were then collected and published together as A Knight of the Seven Kingdoms in 2015.

This is the latest Westeros-based project at HBO. Following the global success of Game of Thrones, the premium cabler moved to develop a number of series set in the world created by Martin.

Of the numerous projects announced as being in development over the years, the only other one to move forward before this has been House of the Dragon. That show premiered its first season in August 2022, earning a speedy Season 2 renewal less than a week after it launched. Season 2 is currently in production. Variety also exclusively reported that HBO is also looking to develop a series set during Aegons Conquest.
