Apate

"Apate" means deceit.   Imagine a world shaped as a bowl. This bowl is the charted world, with terrain gently sloping downward from a circular wall of inconceivably dangerous and perilously high mountains. In the center of this circular world is a vast lake. At the bottom, in the center of this body of water is the entrance to the underworld.   The majority of the gods in this world (at least, the ones the surface-dwellers are familiar with) all house themselves where the mountains meet the sky. However, the eldest and most spiteful god lives in the underworld. This is how I explain gravity in my setting. This elder god spitefully pulls at everything, gently but sternly urging everything to return to where it originally came from.
