Luna and Octavia are busier than ever with the Grand Galloping Gala fast approaching. Both of them have a long night ahead of them, and if all goes well should meet the next morning for breakfast.
Princess Luna, struggling with the loss of the one closest to her, attempts to re-integrate into society after her return from her imprisonment on the moon. All the while, she fights to cope with a growing envy and burning hatred for her sister.
In the beginning, the world was void and without form—and boring as well, since nothing lived on it and there wasn't all that much to do. For a long time the new world lay dark. Then Celestia chose to walk it alone, and there was light.
Raising the sun isn't an easy job. Celestia knows that better than anypony. It requires vision and creativity, and she can only do her best work when the inspiration strikes her. But, as is true with all good art, nobody else cares about that.
