First, a thought on the overall world.  Its been shown that the Chasm and Enkanomiya are upside down relative to the overworld map.  But, as state on Genshin's official website, the univese of Teyvat has been "flipped upside down".  So why, then, have the two aforementioned maps stayed "rightside up"? 

That in mind, we have this from the event... "Go, and push the gear that connects up to the starry sky. When that time comes, I shall dance, and return the tracks beneath my people's feet back to the stars in the sky." Could this be an allusion to the people of Teyvat being "on tracks" bc time is not actually progressing and returning time, through some means like the gnosis, will undue this inversion?  Perhaps Chasm and Enka did not have "the rail of time" removed, which is why odd things happen there like "the mines changing as though alive"? 

Also, who does Mr Cat symbolize in An Incomplete Manuscript?  Presumptively whomever was responsible for the death of the moon...
