A new theory looks at the possibility of the Night’s Queen's return in “Winds of Winter.” Fans of the TV series may not know that the Night’s King actually had a wife back in the day, but very little is known about her since all records were destroyed.

The Night’s King and his wife lived in Nightfort, committing a lot of atrocities during their reign. When the King in the North Brandon and the King Beyond the Wall Joramun joined forces, they were able to defeat them. However, they discovered that the Night’s King made sacrifices to the Others, and all records relating to him and his wife were destroyed.

If the old stories are to be believed, it seems that the Night’s Queen is actually the more dangerous one. The Night’s King was actually the thirteenth Lord Commander of the Night’s Watch who fell in love with a woman "with skin as white as the moon and eyes like blue stars." He lost his soul after he shared a bed with her. So if this Queen is so powerful, will she appear in the next book?

A new theory on Reddit suggests that it is possible the Night’s Queen was taken away and imprisoned after Brandon won the war to wipe out the White Walkers. The Night’s King, however, found a way to turn babies into White Walkers, hence his army. Meanwhile, his wife could have been imprisoned in the crypts of Winterfell.

The return of the Night’s Queen could add a new dimension to the story in “Winds of Winter,” giving fans an idea about the real motivations behind the imminent White Walker invasion. All secrets will only be revealed when George RR Martin completes the book.
