HBO confirmed that they are in talks with author George R.R. Martin for a possible spin-off of the Emmy Award-winning scripted series "Game of Thrones."

According to Entertainment Weekly, the network's programming president Casey Bloys revealed that they are still exploring potential ideas for the story that may delve into the thousands of years of Westeros' history.

"I would say it's still kind of preliminary ongoing talks. There are areas we are exploring, but I wouldn't point to any one and say, 'This is what we're going to do,'" he added.

When prodded if they have finally determined the episode count for season 8, which marks the end of the franchise, "I'll take as much as we can get," the executive simply answered.

Bloys also added that despite the hopes of some fans that the final episodes of the hit series will be made into a movie, he said that the network prefers to focus on serving its subscribers.

"I want everything I can get for HBO, I'll just leave it at that," he concluded.

Forbes shared that if the prequel will be given the green light, two of the possible narratives they can showcase are the so-called "Tales of Dunk and Egg" and "Robert's Rebellion."

The former is said to be an ongoing series written by Martin following the journey of a hedge knight who becomes a Kingsguard legend, Ser Duncan the Tall, and his squire Egg, who apparently would eventually become King Aegon V Targaryen, Maester Aemon's brother.

Their adventures are deemed to take place 90 years before the main events of the "A Song of Ice and Fire" saga. The author has written three installments about the duo which were then compiled into "A Knight of the Seven Kingdoms" book.

On the other hand, Robert's rebellion revolves around the civil war that happened 20 years before current timeline. It can be recalled that both in the TV adaptation and in the novels, it was revealed that House Baratheon teamed up with House Stark, House Arryn, and others to overthrow Mad King Aerys, who is Daenerys' father, ending the Targaryen's rule.

Since there is no official announcement yet regarding the prequel, information should be taken with a grain of salt.

Season 7 of "Game of Thrones" is slated to air in summer 2017.
