"I... have ruled these lands, for a thousand years and some. Roughly more than a year ago, my Sister, Princess Luna, returned to us. Originally, in our previously shared rule, she... became jealous of the attention the Day garnered, and I failed to realize just how deeply it upset her, that she didn't find similar for her Night. She revolted, spurred by jealousy... and I was forced to utilize the Elements of Harmony, to lock her away, on the Moon. For a thousand years."
