Here’s the premise of HBO’s Game of Thrones prequel:
The untitled prequel takes place thousands of years before the events of Game of Thrones. It 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.
