Now that Game of Thrones is finished, fans are already speculating about the announced prequel series. There's believed to be a couple of spinoffs in the future, but the one that will based off the Long Night, thousands of years before Thrones, seems to be the only one moving along so far.

The prequel series is already reportedly set to start filming next month, with the working title of, according to Production Weekly, Bloodmoon, as reported by ComicBook.com. Both blood and the moon are two themes frequently used in George RR Martin's book series, A Song of Ice and Fire.

Unlike Game of Thrones, which is a title that pretty much gives away the basic plot of the series, Bloodmoon probably won't spoil too much about the premise of the upcoming prequel. So far, besides the show's time frame, we know that Naomi Watts, Miranda Richardson, and Josh Whitehouse, among other actors have been cast. Martin and Jane Goldman will serve as creators.

Although production seems to be happening faster than we thought, HBO's President of Programming Casey Bloys has said that the series won't premiere for at least two years.

"I have to get a sense from production when we see scripts for a season, how big and involved it is," Bloys told Deadline this month. "Shooting a pilot in June and having it on the air a year later feels a little rushed, but it’s too soon to tell."

We'll be keeping a close watch on all the details to come from Bloodmoon, if this is in fact the confirmed working title.
