Twilight's caught a special type of flu, and it's up to none other than Princess Celestia to nurse her through it. A special, tender little moment follows in this most unexpected of circumstances.

Celestia makes sure to surround herself with the most competent staff
in all of Equestria, but when they go too far in her service, she takes
things into her own hooves.

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.

This story is a sequel to Off The Edge Of The Map

When Twilight is sent with Luna on a diplomatic mission to Draconia, they quickly find themselves somewhere that doesn't appear on any map, and Luna is lost in more than one way...

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

Celestia has had enough of half-arsed promises from her loyal subjects. It's time to wear a different hat.

Twilight and her friends are approached by Princess Luna who presents them with a set of questions that trigger a long and perilous journey.

Did you ever stop to wonder what became of Trixie, Gilda and Blueblood after your encounters? What did these episodes truly mean to you? What role will they yet play in the lives of the Elements of Harmony?

Last, are these questions as relevant as the journey towards the answers? Who will benefit from seeking these answers - you, them, or I?

Twilight Sparkle wakes up one morning to a harsh dose of unreality. She is stranded, without her friends, on an island which matches no known locale on Equestria. Surrounded and harried on all sides by the alien and the dangerous, she will find her mettle sorely tested, and find perhaps that the best friends you will ever have in your life are the ones you make when your back is to the wall...

Thanks to CedricBale and noobie56xx for tracking down the name of the artist so I could give them credit.

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

TV Tropes

Only fools, madmen, and adventuring parties go into the Malpheggi, the swamp beyond the Everfree Forest. It can be left as an exercise for the reader as to which of these categories Samus Marcus (a Thyatian swordsman, or so he says) and Ivan (his companion in trouble) fall into. When they are rescued by the registered adventuring party, the Elements of Harmony, a grand quest across the D&D world of Mystara begins. Together they face culture shock, international politics, romance, dungeons, and a dragon with a grudge as Marcus learns how to trust his new friends and make up for his past mistakes while the Elements of Harmony try to save Equestria from a threat which proves more... complicated... than they originally thought. Also, pie. And hats. A D&D (Mystara)/MLP Crossover.
