Now, new photos from the set of the seventh season's production have confirmed Ramsey is returning to play the fiery young leader when the show returns next year.
The photos, taken and shared to Twitter by PAP4U, show Ramsey exiting her trailer on set in Northern Ireland, in full Game of Thrones attire.
The images were supposedly taken around the same time the show's other stars - including Kit Harington, Gwendoline Christie, Liam Cunningham, and more - had been confirmed to be in the area.
Of course, this is really no surprise.
Mormont was seen at the end of season six giving a rousing speech to the leaders of the North, rallying them together to support Jon Snow as the King in the North suggesting she'll play a major part in the northern storyline to come.
She also became a fan favourite in record time, prompting many memes and reaction gifs in her honour.
Game of Thrones is expected to return with season 7 around June, 2017.
