When Princess Luna became Nightmare Moon, her sister banished her to the moon with the Elements of Harmony. But in a separate universe, Nightmare Moon was able to turn the tables and banished Celestia to the sun. Because of this Nightmare Moon is the new Queen of Equestria, and while some welcome her rule, there are those who lurk in the shadows, waiting to put an end to the queen's rule.
