It would be inclined to offend a lot of people, I'm afraid, but it's my honest opinion. Our presence here tells me that this cataclysm is multiversal, not just universal. There are people here from alternate Earths, that much I'm certain of. So if the whole multiverse goes, then its attached realms, heavens or hells or Arcadias or Abysses, go with it. Not necessarily because they were wiped out, but because there's no one left to believe in them, so there's nothing to sustain them.
