Finalist and judge's top choice in Equestria Daily's 2012 Nightmare Night contest.

Fluttershy has been plagued by nightmares, and Twilight wants to help her get rid of them. But when the bookish mare begins to pry into the depths of Fluttershy's unraveling psyche, she finds more questions than answers. What do her dreams mean? Why won't they stop haunting her? And why does the creature she keeps seeing inside them seem like more than just a simple night terror?

Distance can drive us apart. It can also bring us closer together.

After all is said and done, and the ponies have gone their separate ways, the only way they have to keep in touch is through letters.

It is the responsibility of a king to care for his people and maintain order in his kingdom. That shouldn't be much trouble for a ruler as powerful as Discord, right? With his faithful and insecure advisor at his side, the draconequus sets out to explore his new world and personally see to it that peace reigns in Equestria.

However, the ponies want nothing to do with their frightening new ruler, and the unamused Spirits of Equestria aim to drag the Spirit of Chaos away before he can cause any more harm. Can Discord be the ruler Equestria needs? Or is he truly doomed to become the monster he is seen to be?

Deep in the Royal Library is a book. A terrible book that is said to send whoever reads it mad. A book so dangerous that it has to be hidden away and secured with chains to prevent it from ever being opened.

A book which has just been accidently checked out by Spike on behalf of Twilight Sparkle.

The Star In Yellow is rising once more, and only Rainbow Dash and Spike can save Twilight before it's too late. Ideas live forever. Ponies do not.

This fic is loosely inspired by the 19th century story 'The King In Yellow'.

Greed can drive a pony to do crazy things. And when Manehattan con artist Masky catches wind of a story about the flashiest gems in all of Equestria, the smell of bits is just too strong to pass up. He'll drag his dragon accomplice through the hell that is an innocent rural town, contending with lecherous grannies, fresh country air, belligerent farmers, a score of hysterical dames, screaming children, and a dangerously business-minded Pinkie Pie to get his hooves on those jewels, or get somepony else to die trying.

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.

Many years after sending her beloved protege to Ponyville, unease sits heavily on Princess Celestia's heart as her relationship with Twilight Sparkle seems to have cooled despite all they've accomplished together. On the advice of her sister, Celestia sets out to investigate and resolve the lost connection with her most faithful student. What does it mean to be a Faithful Student...or a Princess of the Sun?
