Long ago, Princess Luna became very jealous of her sister, Princess Celestia. More so, she was jealous of how the ponies loved her sister's sunlight. When the jealousy became too much, she turned to dark magic and brought on an eternal night. But it wasn't enough-No she needed more than just that. She built an army, abusing the dark power that she had gained and brought a quick war to Princess Celestia.
