A new 'Game of Thrones' prequel, based on George RR Martin's 'Dunk and Egg' books, has been officially greenlit. 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, reported Variety.

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'.
