The pure white destruction comes directly after X∞. It is nothing but white, and Greegee was the cause of it.
No atoms of dark matter are found anywhere at all. All there is, is nothing but white, white and more white. It went on for twenty years.
Actually, along with dark matter, all traces of EVIL were lost as well, so there were no killers, people attacking others, and wars.
So the place is the nicest place in the whole history of time. For now...
