Westeros is coming back, yet this time the hit Northern Ireland-based series will be getting a prequel as network executives give the project a green light.

The Belfast Telegraph reported that the series’ US-based production company has requested a pilot episode of the prequel, but this will most likely not come out until the final season of Game of Thrones is wrapped-up in 2019. It is said that the new show will probably come out sometime in 2020.

As written by the author of the series, George RR Martin, the prequel will take place around 1,000 years before the current series and battles over the Iron Throne in the ‘Age of Heroes’.

It will tell the story of “the world’s descent from the golden Age of Heroes… [and] from the horrifying secrets of Westeros’ history to the true origin of the White Walkers, the mysteries of the East, to the Starks of legend,” as an official HBO statement said.

Details about the plot are under close tabs at the moment, but knowing that Martin is behind the project can guarantee that the program will have an amazing setting, premise, and characters for sure.

The new series will have many referenced characters in the main series, such as the ancestors of existing characters and founders of the Stark and Lannister houses, Bran the Builder and Lann the Clever, respectively.

The success of the prequel and whether or not the production company decides to proceed with a full series, however, is reliant upon how well the pilot performs, so we’ll just have to wait and see.

Are you looking forward to the prequel?
