George R.R. Martin, the author of the A Song of Ice and Fire book series that inspired HBO's Game of Thrones, never seems to be short on new ideas. Currently, he's working on multiple shows for HBO, including multiple prequels to Game of Thrones. 

Now, Martin has mentioned yet another concept based on his work that he would like to see on televisionnot a prequelbut a story that focuses on the common people of  Westeros and runs concurrently to Game of Thrones, which is set to air its highly-anticipated final season next year.

In a new interview with The New York Times, Martin likened his new idea to the classic movie Rosencrantz and Guildenstern Are Dead, which retold Hamlet from the perspective of two minor characters. "Hamlet is going on in the background, but it’s all about Rosencrantz and Guildenstern," Martin explained. "I wanted to do a show called Spear Carriers, which would actually be set during the events of Game of Thrones, but it wouldn’t be following Dany, Tyrion and Jaime. They would all be there in the background like Hamlet."

Martin went on to say, "It would be more like, 'Here’s a story about a guy in the City Watch; here’s a story about a prostitute at one of Littlefinger’s brothels; here’s a story about a mummer who’s in town to do juggling and tricks.' And they all get caught up in the events. I think that kind of show would be a lot of fun to do."

Although A Song of Ice and Fire features a wide variety of characters from different walks of life, and Game of Thrones has stayed true to that spirit with its large diverse cast, the cornerstone characters tend to be royals or nobles, which is a necessity for portraying the political intrigue that's so important to the show's plot.

Little is known yet about Martin's upcoming television projects, so it's not clear if he'll ever have the time and space for this particular spin-off. It doesn't seem likely that Spear Carriers is already counted in the list of Game of Thrones-inspired series already being developed or considered by HBO, as Martin admitted freely, "I haven’t been able to convince HBO that this is a good idea yet, but I would actually love to do something like that."

Considering his success so far and his influence on the genre, any idea that Martin would like to develop probably has a fighting chance. As he mused, "Maybe I’ll be able to convince them to do it!"

While one still-untitled Game of Thrones prequel is in development at HBO and has already cast Naomi Watts and Josh Whitehouse, Game of Thrones will return for a final six-episode season in April 2019.

Another show based on Martin's work, Nightflyers, is currently airing its first season on SyFy.
