The end of the universe as it implodes into itself, MidJourney
At Order 8 of Lithias, it is believed that as God is the Universe itself, there will be a day in which the universe will die, and all our souls and spirits, as well as those of the demigods, will be erased from existence. Given a multiverse theory (which Lithias does not rely on, but amuses) we would all go on then to have parts of us turn into the various new Universes, and subsequently new Gods.
With this Multiverse Theory in mind it would be that the Universe is alive, and part of a virtually infinite multiverse. As one Multiverse dies from aging too far without successful life, it does not go on to giveaway to life to new Universes. For the Universe more fit to create life in a successful and rather rapid manner, it will die an earlier death when an unknown goal is met, it will burst into parts each with maybe slightly varied Natural Law. This is just like the reproduction of organisms in Reality, where-in fitness will vary and over time lead to more and more fit organisms.
Keeping in mind this potential path of fate, it is hoped and trusted that our universe will succeed at reproducing, lest we otherwise be fully forgotten in the scheme of the multiverse.
Once again, this model for the multiverse is not relied on by Lithias, but it is amused by Order 8, Order 8 at its base is still valid with different multiverse models, but those tend not to flow as naturally.
