No. None at all. The only key element I have to go on-

-is the fact that the location he retreats to that I mentioned prior, was a full world he left simulating in the back of his mind. A planet with an imaginary society that’s just disappeared. And if it’s gone because something happened to it, then someone is out there with more knowledge of our past than I believed to still be around.

Could his mental state have something to do with its disappearance? Simulating one’s past like that would be considered clinically unhealthy behavior.
