This story is a sequel to A Friend of the Night

So it's finally happened. The reign of the Princess Sisters has come to an end, with new blood Twilight Sparkle taking over the reigns. It's been a long time coming, in truth, and Equestria as a whole as well as the Princesses themselves will likely benefit from the change of pace. But change is still a frightening thing, just due to the sheer... uncertainty of it all.

Fortunately for Luna, there's still a constant in her life. A little, green, fast-talking, mischievous constant.
