A gloomy feel has taken over the ponies of Equestria. Small and sudden tremors keep occurring and there's a small purple void in the sky, striking fear and anxiety into the hearts of residents in Equestria. Every day it grows larger and larger, and hope keeps waning and waning. Prince Shining Armor hasn't been seen since the day that the void appeared in the sky, either. This wasn't a mere coincidence, this was the end of the world.
