This story is a sequel to On Getting to the Bottom of this "Equestrian" Business

A magical accident causes the personalities of the future Mane Six at the moment of getting their cutie marks to be swapped with those of their human counterparts during the Freshman Fair. They have only three days to figure out what’s going on and find the right individuals to help them: Princess Celestia in Equestria and the newly-arrived Sunset Shimmer on Earth. In three days the mirror portal will close, and anyone not swapped back will be trapped in the wrong dimension and body for thirty moons.

Note #1: This story is set in the same universe as my earlier novel On Getting to the Bottom of this “Equestrian” Business. I’m using the rules I established in that story for how the Equestria Girls setting works, but nothing from the plot, and since it’s twenty-five years later, you might as well start over with the characters anyway. That’s why I think you can read this story without having to read that earlier fan-novel first. Therefore, I’ll be including author notes as necessary to catch you up on those rules.

Note #2: I use “H” for “Human” or “P” for “Pony” before a character name to refer to the mind, not the body. So “P. Rarity” is the character that starts out in a pony body, suddenly finds herself in a human body, and struggles to get back into her pony body by the end of the story.

Note #3: For the human parts of this story, I refer to the “Freshman Fair”, an event that happened in the comics. All you have to know is that it was an event held during school hours at Canterlot High when Applejack, Rainbow Dash, Fluttershy, Pinkie Pie and Rarity were freshmen. It existed in order for the various school clubs to advertise themselves and gain new members, and it was at this event that Applejack and company all met for the first time and decided to become best friends. (Oh, and Sunset Shimmer as president of the yearbook committee later interviewed each of them about the event, gathering the facts she would later use to tear their friendships apart.)

This story is a sequel to The Visiting Team -- Part II

Princess Luna wants to return her nightmare guards to the dark realm from whence they were summoned. And there's just one pony who can help her with that: Trixie Luna Moon. With her Advanced Projects team, of course...

Since it's been a while, here's a quick recap for those new to the Advanced Projects series:

On an alternate branch of the G4 timeline, Twilight Sparkle never left Canterlot and is now an Acting Princess, with a very different group of close friends: Tempest Shadow, Starlight Glimmer, Trixie Luna Moon, Sunset Shimmer, and Moondancer -- plus Cheese Sandwich as their on-call party pony. And each of these has had a very different past, as a result of meeting Twilight Sparkle so early.

In particular, Trixie was once the Great and Powerful student and protégé of Princess Luna... while she was Nightmare Moon. Which has its consequences...

Earth-pony Twilight Sparkle has always been a little "out there". But while testing her latest crazy idea, she finds that there are places even farther than that...

What does it mean to be a strong nation during a time of peace? What happens when all around you look to your state with wariness, suspicion or fear? What place does your homeland have in the future of the world? These questions and more plague the mind of Sunset Shimmer, recently promoted Colonel of the great Imperial Army. Thankfully though, she is not alone to consider them.

It's not often a literal toss of a coin can decide the course of your entire life. Rarity's work is interrupted by the memory of just such an event in her own.

Also stars Rarity's parents, Hondo Flanks and Cookie Crumbles.

The most powerful sorcerer in history rescues a young Princess from her own curiosity, and helps her found a new Empire. But the sorcerer has her own reasons for doing so -- and they're not nice reasons...

In canon, Sacanas is only mentioned in passing as the creator of the Staff of Sacanas, used by Tempest Shadow in her attempt to conquer Equestria. Yet what kind of sorcerer would fashion a staff designed to steal the magic of alicorns? Why was Tempest, while wielding the Staff and its power, so implacably, coldly vicious? And why does history seem to say so little about such a powerful mage? There's a backstory here, and this is my take on it...

One final note: I do not agree with or defend the opinions expressed here. My intent is merely to explore the question: can a pony somehow end up doing all the right things, for all the wrong reasons?

For a thousand years, the alicorns of House Solaris have ruled over the ponies of Equestria with wisdom and care. Now, in the present, Twilight, youngest daughter of the Queen, goes about her day as befits a Princess of the Realm.

Did you know Fluttershy was made Royal Game Warden of the last remaining Royal Game Preserve in Equestria? Of course, she only has that title because the newly winged Twilight needed something with which to defraud the government, and that "preserve" is, due to centuries of neglect, actually the Everfree Forest, but that's not really important.

Until, of course, the Griffon Ambassador showed up at her door demanding her services as a hunting guide for his lunch.

Then it was a little important.
