Hypothetical far-future chronology: let's say, the second version of the original world is shown to exist for 200,000,000ish years, and by then, they've discovered 9 total other universes, one of which is so large (in some sense) that exploring it is what made for the gap between the discovery of the 5th and the discovery of the 6th. Still, the ur-destroyer has not awoken/returned/been released, and no proof has been found by the explorers that the entity still exists. So, the question of the Second Destruction is thus far unanswered.

("What about the tangent you imagined at the end, where a band of adventurers stays behind to square off against the emergent ur-destroyer at the last? Who are left there like that as a little last mystery for the readers? Like, that's all the reader is given to 'know,' that at the end, there was this squad, and they tried something, maybe it worked, maybe it didn't, everyone else had escaped that world so..." Yeah, true. Well, I guess that turns on whether the bizarre ethereal sci-fi post-narrative is worth writing more strongly than that scene? Or we adapt the idea some. Suppose either way that, when mortals left the destructible world when the ur-destroyer did at last re-emerge into their world, then the escapees did not find out what happened, not as a matter of common/public knowledge thereafter. Whether the adventurers "saved the day," whether the world was redestroyed but then recreated again, or redestroyed and left that way, etc. none of that is automatically given to be known to the reader via the POV of the final epilogue/coda, arguably. So, instead, from the invincible realm, explorers have gone out, and they know not how many other universes there are "period," but they assume that the more they find, the likelier it is that there are as many as can be.)
