So once again the day is saved. Literally. In this case, by that new unicorn who came into Ponyville and fought Nightmare Moon, the nightmare that would never end (until it did).

They say this unicorn is strange. They say she's a princess and a witch, who lurks in dark libraries and tames mighty dragons.

Well, Dinky knows that's bunkum, but who cares? She's never turned down a quest, not with her Sisterhooves Sisters in tow.

What a team they are too: Odd Job, carrot-farming sister and cosmic punching bag; Apple Bloom, who's got the heart of an apple (and the imagination to match); Alula, the pegasus who couldn't be more pegasus if she tried (harder); and Piña Colada, who's what you get as a sort of add-on if you seek out Berry Punch's beverages.

Together, they will bravely and nobly discuss over drinks what to do about this new hero in their midst, and see if they can fit her into their usual playtime. After all, it wouldn't be much of a quest if it wasn't dangerous. Twilight will just have to take her chances.

“Somethin’ tells me we ain’t in Ponyville no more, Winona.”

After being misled into drinking a mug of experimental tea in Twilight’s home, Applejack ends up jumping back and forth in pony history, and she doesn’t like it one bit. But the history books need editing: the stories aren’t following their original courses, and it’s getting worse with each century. Ponies are vanishing from their places in space-time. Now far away from home, Applejack just happens to fill a niche in a new discipline: time-travel rodeo.

With the guidance of Twilight Sparkle, who in turn is guided by Spike the dragon, who in turn is guided by a really snazzy Dewey Decimal System, Applejack must impersonate famous ponies from the past and re-enact the events that made Equestria history. It’s a tough job, but somepony has got to do it. Who better than ol’ reliable herself?

There’s just one catch: if she fails, Applejack will cease to exist.

With an assortment of astronomers, archaisms, after-eights, apothecaries, aardvarks, anti-ageing acid, atomic magic bombs, and – of course – lots and lots of apples.

When Twilight and Spike are summoned by Rainbow Dash to Zecora's hut, they're alarmed to discover that Fluttershy has a parasitic plant attached to her back. Unfortunately, getting rid of this monstrosity is only one of the problems they'll have to confront...

The first alicorn to be born rather than made. A pony of incredible power. A pony with a very important destiny.

Under the guidance of the fretful Princess Twilight, the sardonic Spike, and the ever-loyal crystal ponies, she will rise from the ashes of a childhood nightmare to become the princess she was always meant to be.

The journey won't be easy, but she won't give up. She was meant to be the Crystal Princess. That is her purpose.

And she will stop at nothing to keep it that way.
