Ponyville was first founded by earth ponies, but they wouldn't always be the only kinds of pony who would live there. Eventually, unicorns and pegasi would also call that little town their home, and Granny Smith, in her younger days, was right there to witness them when they first moved in.

Though there were a few bumps along the way, Starlight Glimmer now stands as the new Head Mare of Princess Twilight's School of Friendship. Today is her first day in the role, and to mark the event, she's decided to take the first class with the students. But there is one question. What to teach them?

The centuries-long rule of Celestia and Luna has come to an end. Now, it is Twilight Sparkle, the Princess of Friendship, who watches over the ponies of Equestria. To stand as leader of a whole nation is a daunting thing, but the young alicorn is more than ready. With her closest friends by her side, she's ready to face this great challenge, one day at a time.

Nightmare Moon is defeated, and Twilight Sparkle and her friends are the ones responsible. There are celebrations abound as all of Ponyville celebrates this momentous occasion. But for Twilight, there is still much to do, for the Elements of Harmony have shown her what true power really is. And so she and her newfound friends will use that power, and use it well, knowing that one rogue alicorn is not the only problem Equestria has to deal with.

With newfound confidence in both herself and her magic, Twilight decides to take a bit of a late-night stroll outside of Ponyville in the wake of the Ursa Minor incident. But when she does, she finds, to her shock, that a certain mare has not made quite as much of an exit from the town as she first suspected.

Having succeeded in their task of convincing the dragon to leave his mountain home, Twilight and her friends are of course delighted that things are getting back to normal. But shortly after their return to Ponyville, the young unicorn gets a surprise visit from the heroine of the hour, Fluttershy, who has something she needs to ask her.

Though Cadance is happy that her daughter Flurry has shown an enthusiasm for following in her hoofsteps, the older Princess knows that she still has a lot to learn. So, during a quiet afternoon together, she decides it's high time to teach her daughter some important things.

When Twilight first arrived in Ponyville, her faithful assistant Spike fell head over heels for the glamorous Rarity. But what if it hadn't been her that the little dragon had grown a fondness for? After all, Rarity wasn't the only mare he'd met that day.

Twilight Sparkle, the Princess of Friendship, is renowned across Equestria as being perhaps the greatest master of the arcane there could ever be. But Twilight herself knows that there is one pony who, despite not being an alicorn, has managed to successfully hold her own against her. So, despite years of friendship between them, Twilight decides that it's time she and her first student finally settle the question of who is truly the top mage.

Though Starlight knows a great deal about Twilight and her life in Ponyville, she is nevertheless curious about what that life was like prior to her arrival onto the scene. Discord, who is always up for getting involved with things like this, decides to show Starlight perhaps the most important part of Twilight's earliest days in the town.
