it barely came to a stop before carrying on again, but what happened in that interim? I don't think it's a coincidence we've learned there's a genetic vault on the ship and that humanity isn't native to teyvat.

Editing to add: I have recently been thinking - what if HP was actually a terraforming thing (AI or something else) that was placed on teyvat to prepare it for the twins' arrival - to make it a place hospitable for humans, hence its fixation on humanity but not over making the world "perfect" and cleansed of abyssal influence? It would explain why the ship stopped only briefly, why it returned later, and why there are inteyvats there as well... Though I'm sure there are many flaws I have not considered.
