10 years ago, Nightmare Moon would stand before a crowd of earth ponies, unicorns, and pegasi and be met with gasps of horror at best and boos of disgust at worst. But it was not 10 years ago, since then, Equestria had changed.

In fact, long gone was the day itself. Now, on this night, ten years after her return, the ponies by and large loved and trusted their new Empress, their Empress that brought them out of vulnerability, their Empress that uplifted thestrals as the respected and integrated fourth tribe of Equestria, and their Empress that would usher in the New Lunar Millennium!
