As Game of Thrones is coming to an end, HBO is now gearing up to reveal a number of spin-off series, so fans won’t miss George R.R. Martin’s epic storytelling that much. In fact, one of them is now in development and will soon hit the small screen.

The 69-year-old author is now hard at work and, in fact, is working with five different sets of writers for these upcoming television shows. Regarding that, HBO chairman Richard Plepler said at the MIPCOM entertainment conference in Cannes on Monday that he is impressed with the pitches he has been receiving so far.

The start of the spin-off series

The “Game of Thrones” spin-off series is set before the current television show takes place, Digital Spy reported.

Now that it is in development, Richard Plepler said that he is amazed by the “fantastic group of writers and talents” that are working hard on it. As a matter of fact, most of the people building the series are from “GoT” staff and crew so, they know perfectly well what they are doing and are very familiar with its 'ins and outs.'

"I think we will find with this embarrassment of riches an exciting property for us to move forward with,” Plepler went on to say about the spin-off series. They are now “looking at some things.” He even read old bibles and he is excited by what he saw.

Bryan Cogman, the man from “GoT” team, will be officially on board in one of the spin-offs. However, “GoT” creators and executive producers David Benioff and D. B. Weiss will be doing something else - “Confederate,” - when the epic television series based on “A Song of Ice and Fire” ends.

They won’t be working in any prequels.

Spin-off series’ other details

Richard Plepler didn’t reveal anything about “Game of Thrones” spin-off series’ storylines so fans still have no idea what they are about to see. Other crew members from the outside that will be joining the making of the prequels are Max Borenstein, Jane Goldman, Brian Helgeland and Carly Wray. But, George R.R. Martin will be working with all of them in different phases. He also revealed that he is “co-creating” Bryan Cogman’s project.

Plepler also revealed that no prequels will be released until “Game of Thrones” Season 8 ends. Now that Jane Goldman has finished writing her script, the others, too, might be almost complete. Martin even teased that the earliest it could hit the small screen is in 2019, the same year “GoT” is about to come to an end. But knowing the author, it could be later than that.
