During Celestia's early days as the ruler of Equestria, Canterlot suffers a crisis. They're having a shortage of food, and have no energy to keep working. Celestia, obsessed with being a good Princess, and holding her power as long as possible, turns into a tryrant. In order to have as much power as possible, she creates fear and unhappiness between the citizens of Canterlot. Luna is aware of this situation, and does something about it...something much worse than Celestia´s tyranny. It's Celestia's duty to protect her citizens from her wicked sister, and learn what being a leader really means.
