It has been many months since Discord's defeat but after such a destructive war, nothing will truely be back to normal. While Equestria was saved for such a horrible fate, Earth still remains a scorched ruin; laid to waste by Discord's forces. It has fallen to such a great evil and will never truely recover.
Or maybe... Just maybe... there is still hope left for it.
