So, it's our Earth. And, we desstryed it once already. I agree with your post at Westeros, that Father Earth is a entity that was awaken when Orogenes, Guardians and whoever else started fucking with him.
The magic is what ties everything together for me. It turns oroogenes into Stone Eaters, it's wheat controls the Obelisks and the Guardians. The question is, who is behind the magic? So, Schaffa seems to want Nassun to bring the moon back, isn't that what How wants Essun to do also? Is that what Alabaster was trying to do also? Or, was he just trying to completely destroy the world, a and wants Essun to finish it off? Confused about that part of it.
