HBO's Game of Thrones prequel is already filming under the working title Bloodmoon, but a leaked logo may confirm it as the show's official title. Earlier this year, HBO announced the prequel series would begin filming in the summer, and the Bloodmoon working title was first revealed at the start of production. However, creating a logo for a working title is unusual, which suggests it could, in fact, be the Game of Thrones' prequel's actual title.

The Game of Thrones prequel series is set thousands of years before the setting of the hit HBO series, so the two shows won't exactly be directly linked. Still, the prehistoric setting is a period in Westeros called the Age of Heroes and it is when many of the Great Houses of Westeros (Stark, Baratheon, Lannister) were first founded - or so the legends say. The Game of Thrones prequel series will explore the time when the land's myths were first born, and this may also include a further explanation for the origins of the White Walkers. Because of this, many had taken to referring to the prequel series as The Long Night. Even A Song of Ice and Fire author George R.R. Martin uses that title, though he did clarify that The Long Night isn't the official title of the show.

And to be fair, Bloodmoon may still not be the Game of Thrones' prequel series' official title either, but the reveal of the logo (which can be seen at Watchers of the Wall) makes an argument for this being the official title. The photo is a close-up shot of a production sheet, and what is shows is the word "Blood" above the word, "Moon" where the second "O" in Blood is reflecting to become the first "O" in Moon. Separating the two words is a spear, a common weapon in Westeros and one that dates back centuries given its relatively simple construction. It should be noted this is merely a photo of the image printed on a piece of paper in black ink, not a full color presentation or piece of key art for the series, but if legitimate, this would be our first look at the logo for the Game of Thrones' prequel series and a confirmation of its title being Bloodmoon.
