Following a dramatic debut season finale, 'A Knight of the Seven Kingdoms' isn't showing any signs of slowing down yet. The 'Game of Thrones' prequel, set roughly 100 years before the events of the flagship show, is based on the 'Dunk and Egg' novella series by author George R. R. Martin. Season 1 depicted the events from the Ashford Tourney, during the course of which Westeros witnessed its first-ever Trial of the Seven in several years. Towards the end of the first season of the HBO Max show, Peter Claffey's Ser Duncan the Tall had once again hit the road as the brooding and solitary Hedge Knight, accompanied by Dexter Sol Ansell's Prince Aegon 'Egg' Targaryen. Season 2 is now set to return with more characters.

According to The Hollywood Reporter, 'A Knight of the Seven Kingdoms' has cast Lucy Boynton of 'Bohemian Rhapsody' fame to play Lady Rohanne of Coldmoat, also known as the Red Widow. Babou Ceesay, who was previously seen on 'Alien: Earth', will be portraying the character of Ser Bennis of the Brown Shield, and 'Westworld' star Peter Mullan will be playing Ser Eustace Osgrey of Standfast in the Reach. As is already known, the second season will adapt the novella 'The Sworn Sword'.

In terms of the plot, Season 2 will unfold amid a severe drought. Dunk and Egg would be drawn in to negotiate a peace settlement between two warring houses who are fighting over the rites of passage of a river. It was previously reported that, to realistically portray the drought-ravaged landscape, the production team will be filming several scenes in Spain rather than in Belfast, Ireland, where much of the debut season was photographed. 



Speaking about the upcoming sophomore season, showrunner Ira Parker had revealed, "It’ll still be six episodes. I think the scope will be the same, maybe even smaller. The budget has stayed the same, but everything is more expensive due to inflation. Plus, book two takes place in a drought, so we can’t shoot exteriors in Belfast. We have to go to a sunny location with no water, which costs money — that’s a major expense we didn't have in season one. I’m having a lot of fun with season two. It’s going to be a different season, and, I hope, for the better.” 

The star of the 'Game of Thrones' franchise is evidently on the rise as the prequel show's season one finale averaged 14 million U.S. viewers across all platforms and 26 million worldwide, as per statistics made public by HBO. This has prompted the network to further expand the universe of the fantasy shows, with Warner Bros. officially confirming the development of a 'GoT' movie based on King Aegon I Targaryen’s conquest of Westeros. The movie is being written by Beau Willimon, who was previously the wordsmith on 'Andor'.
