Game of Thrones doesn’t reveal much about the Night King’s true identity before season 8 is finished though what we know about the villain tells us he could have been a Stark. Of all the Great Houses of Westeros, House Stark is one of the most important throughout Game of Thrones. The Starks play a pivotal role in George R.R. Martin’s books, and this carries over into HBO’s TV adaptation. They’re heavily involved in defeating the Night King in the series, but several of the Starks also appear to have a connection to him.
