Whether you were happy with the way Game of Thrones ended or not, you probably weren’t ready for it to end. Lucky for you, you won’t have to wait too long for your next dose of Westeros. A long-rumored Thrones prequel is in the works, and it’s already begun filming in Northern Ireland — the same location for much of the original series’ filming. The prequel doesn’t have a title yet, though it will be set during the Age of Heroes, thousands of years before the events in Game of Thrones.

So far, according to the Belfast Telegraph, filming has taken place at a secret location in County Down, on the north coast of Northern Ireland, and Titanic Studios in Belfast. Many hope the show will touch upon the origins of the Night King, the founding of the great houses of Westeros, and of course, plenty of dragons.

HBO has been rather tight-lipped about the new series, however, saying, “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, only one thing is for sure: It’s not the story we think we know.”

In addition to Naomi Watts, who will play the series’ lead, the show will also star John Simm from Doctor Who and Life on Mars, and Miranda Richardson from The Crying Game.
