The alicorns have seperated themselves from pony society and conduct research in secret.

At the same time a young Princess Celestia can't wait to meet her new baby sister, little does she know this day will be one of the worst she will ever experience.

Returning from their honeymoon, Shining Armor and Cadence have organized a get-together in Canterlot for their friends and loved ones. Twilight and the other elements are all invited, and the invitations mention that Princess Cadence has a special announcement!

If only they had known that this announcement would turn their world upside down.

We all know the story of a human ending up in the land of Equestria.
Battles of magic, facing monsters and villains, self-discovery, friendship, and eventually a chance to go home...

But what if he didn't go home? What if he stayed and made a life there, in his new equine form?
This, is the end of that story.
