Canterlot plays host to a changeling wedding. For the queens being wed, it will be a day of unity between their disparate clans--if they can keep from killing each other first.
Six stallions must use all their willpower in order to harness powers of Elements of Harmony and stop Nightmare Moon from casting an everlasting night.

It was never supposed to end like this. Princess Cadance has saved all of Equestria from the changeling threat. What comes next isn't going to be half as easy. One wedding may be cancelled, but a new engagement has begun.
