This story is a sequel to Hello From The Other Side
Princess Celestia and Princess Luna have ruled Equestria for many generations and have now decided now in this time of peace to step down. While passing the torch to Twilight, they have many things they want to do now that they're free from the constraints of rulership. What could possibly go wrong?
Note: While this is a parody of the (possible) upcoming Season 9 premiere, do know of course this is (again) a parody and does not reflect the events that will probably take place during said premiere.
