HBO has announced that Game of Thrones fans are about to learn about the "Horrifying secrets of Westeros's history." If that doesn't sound intriguing, then you're probably not a fan of the hit HBO series. For those who are fans, this is a huge bit of news. The network has officially picked up one of its Game of Thrones prequels to pilot as announced today. The project is untitled at this point, or at least to the public, and it comes to us via George R.R. Martin and Jane Goldman, who was the screenwriter for Kingsman.

Jane Goldman co-created the Game of Thrones prequel spin-off with George R.R. Martin. The duo wrote the story together while Goldman wrote the teleplay. Goldman will also serve as the showrunner while she and Martin will executive produce the new series. HBO had this to say about the new show.

"Taking place thousands of years before the events of Game of Thrones, the series chronicles the world's descent from the Golden Age of Heroes into its darkest hour. And only one thing is for sure: from the horrifying secrets of Westeros's history to the true origin of the white walkers, the mysteries of the East to the Starks of legend... it's not the story we think we know."

The "horrifying secrets of Westeros's history" is enough to sell just about every fan of Game of Thrones. While nothing else has been revealed about the new prequel series, it's plenty to go off of for fans who have been waiting for any bit of information about these new prequels. Jane Goldman is one of four writers who were given the opportunity to develop a Game of Thrones spin-off series.

In addition to Jane Goldman, the other writers developing the projects have been Max Borenstein (Kong: Skull Island), Brian Helgeland (Legend), and Carly Wray (Mad Men, The Leftovers). All of the writers have been reportedly working with George R.R. Martin in various different levels of involvement to get a new Game of Thrones series off of the ground. Before anyone gets too excited, it seems highly unlikely that all four of the projects will end up getting a pilot ordered from HBO, no matter how hungry fans are for more content.

Fans have been waiting to get any information about the final season, so this is just bonus news and more to get excited about.
