Yeah I didn't do a fantastic job retelling the theory, which can be found here:

"We have some clues to what that cause might be. Daenerys, Jon, and Robb, all magical children with the traits of their ancestors, were born roughly at the same time. Daenerys was the first succesful Targ to hatch dragons since they died out, and Jon and Robb are the first Stark wargs since... whenever they stopped being wargs."
I mean it's the top voted post on /r/asoiaf of all time so it at least has some good points.
My only contention with that theory is if the Night's King was the person who ended the war, why would human race get rid of him and then wipe him out of the record books? Why destroy the only record of how the war was won?
