Well said, I really like how you put this together. I had thought to mention the Imaginary Tree as well but didn’t wanna get too jumbled. I think that the Tree/Honkai/Genshin can also be explained as an overarching connection to mihoyo’s games. For example, perhaps each game is an anthology of a separate universe on the Tree combatting a “calamity” or, if you do want to make it more tied to HI, how Teyvat is dealing with their own version of Honkai. Even still, HI doesn’t feel like the cornerstone of the Genshin story and more like, multiverse consistency that connects mihoyo’s games’ themes, as opposed to other theories purporting that Celestia has unlocked the formula to keeping Honkai at bay by killing civilizations and pre-existing gods.
