Through unknown means, Sombra amassed an army and launched an attack against the Crystal Empire and a changeling sub-hive. This forces Celestia and Chrysalis to meet, and agree to a temporary alliance between their kinds. Neither is happy about the situation, but for the lives of the ponies and changelings they lead, they are willing to do what is necessary.

Yet, as weeks and months pass, the pair find working together is not as horrible as they originally believed. Is a lasting peace, and perhaps more, possible between ponies and changelings, between a princess and a queen?

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

Twilight Sparkle has always ignored Hearts and Hooves Day, seeing it as just another normal day with extra chocolate and the occasional broken-hearted friend to comfort. But when Rarity convinces her that not having a date during the holiday is contrary to proper princess protocol, Twilight rushes to do everything in her power to live up to the expectations presented to her.

There’s just one problem, though: Twilight has never been on a proper date before.

After a few rather disastrous attempts to find a date in Ponyville, Twilight goes to her mentor in Canterlot in a last ditch effort in the hopes of finding the answers she seeks. Princess Celestia, however, may have something more for her than either of them had anticipated.

Dismayed after her loss to Chrysalis, Celestia departs the royal wedding reception early, retreating to her royal chambers to console herself with a bottle of wine. Concerned for her sister, Luna soon follows to check up on her...

Twilight Sparkle has always loved Celestia—as a friend, and a mentor, and something else as well. And she finally, finally found the courage to admit those feelings.

Celestia turned her down as gently as she could. That's what she thought, anyway.

But the night is still young—and it's a night for being wrong.

[Rated T for suggestive sexual content. This story takes place between the Season 2 and 3 finales. Additionally, I wasn't able to find the artist who did the cover art, if anyone knows please drop me a line so I can credit them.]
