Rarity's exploits in "Sweet and Elite" set in motion a chain of events that will find the unicorn dressmaker taking part in the greatest airship race in the world, the Alicorn's Cup. Excitement will give way to terror, as Rarity soon finds herself the victim of a plot against Equestria, and shipwrecked far from home with her least favorite stallion, the boorish Prince Blueblood. Rarity will learn of treachery in Canterlot and abroad, and will have search for something of substance beneath the prince's obnoxious veneer as she struggles to not only save herself, but her entire nation.

No OCs. The challenge is in shipping something not seen before, is it not?!
Don't bother checking the character list either. I won't spoil the identities there. Maybe when all the chapters are done and online. Maybe.

This story is a sequel to The Best Night Ever

Final Arc - The Black Wedding
CH63 - If I Had a Heart
- The ponies of the Fourth Tribe are ascendant. Shining Armor hunts down his changeling "daughters," and even Lady Antimony won't get in his way. Meanwhile, high above the burning city of Canterlot, a long awaited reunion occurs, and Twilight confronts Alpha Brass and makes a final decision.

It began with a mare from Ponyville and a time-looping Prince from Canterlot. This most unlikely union now stands at a crossroads: a ruthless changeling invasion; a conspiracy within the highest circles of the Equestrian aristocracy; a half dozen power hungry noblemares looking to become a Princess in all but name. With the prize of Canterlot and its Platinum Crown at stake, it falls to six Elements of Harmony to once again save not just Ponyville, but all of Equestria.

Someone out there made a playlist for Platinum Crown: Rarity, Blueblood and Chrysalis. Pretty sweet!
Wish I knew who, or even when they did it, though. I especially like the Chrysy playlist.

Bon Bon's voice is funny, and that's about all that anypony who meets her notices, as her marefriend Lyra soon steals the spotlight with her explosive personality, strange obsessions, and curious beliefs. And why not? Bon Bon is, after all, a perfectly ordinary, boring pony in every way but two: her voice, and the carefully kept secret that she isn't really a pony.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.
