Cruel Gods

From on high, the gods make sport of the mortals who toil below them. None know the cruelty of these beings better than Twilight Sparkle, a beautiful magician who was torn away from her friends by the gods’ divine hands. Granted immortality, Twilight Sparkle now whiles away her days in an inescapable miniature garden for the amusement of the gods, particularly Celestia. But the gods themselves are no strangers to the boredom of eternal life, and as Twilight Sparkle quickly discovers, they will do anything to keep themselves entertained, both at her expense and at one another’s.

I read this manga called "Olimpos" a while ago, its quite philosophical and a bit hard to understand but I felt like Twilight and Celestia could easily be transfered onto Ganymede and Apollo. Luna could easily be either Hades or Artemis, and Fausticorn would easily replace Zeus.
After all the rumours about Twilight becoming an Alicorn herself, it feels like its even more fitting.
