Inb4 calamity actually happens because they're treating unique species so terribly like this. I bet the 1st one got bullied cuz they're jealous and then calamity ensued.
Maybe? Honestly after they showed Earth, maybe the 6 spirits of the divine beasts might be outsiders and the spirits that Lusha can see and protect her might be the native spirits? Maybe world is trying to create its own divine beasts to lead the spirits since we already know that Light and Dark spirits exist?
Regardless, it looks like the world wants unique species to exist as a way to force the stagnated rotten water to start flowing once more
