Have Spike take the C.M.C.'s on a tour of Canterlot so that they don't interrupt Braeburn's ceremony? It was such a simple solution, but even the best laid plans can go awry. Now, Luna and Applejack must contend with some unfinished business from the princess's past as Twilight deals with the fears and concerns of two little fillies... and two little dragons.

Nightmare Night! Rainbow Dash's favourite time of the year.

Well, it would be if she wasn't cooped up amongst the upper-class of Canterlot.

Taking matters into her own hooves, Rainbow Dash breaks out an old costume and goes to show the Canterlot elite what a real nightmare night is like.
Little does she know somepony else already has the same idea...

After working on a major project for the betterment of Equestria, Twilight Sparkle brings her work to her mentor and princess for approval and funding, and her proposal is rejected outright without explanation or sympathy.

Devastated by Celestia's refusal, Twilight tries to determine whether she has failed her work or her teacher - and wonders what her special status and talent is worth.

This story is a sequel to Only Got 100 Years To Live

Celestia has dropped a bombshell on Twilight. Her, growing wings? How can a normal--well no, she's no longer a normal unicorn: Normal unicorns get old; she hasn't.

What is she, then?

Twilight Sparkle is outliving all of her friends, and must come to terms that she has many more years in front of her.

Set before the end of season 2.

The storm is breaking on the Horizon.

It's been two months since the battle against Nightmare Moon. Luna is recovering, Celestia is busy turning the government back into a diarchy, and the Mane Six have returned to their lives. All seems well, but when Celestia discovers that half of the power of the Elements of Harmony have been transferred to each of the Bearers, she decides to send thirteen mysterious members of the Royal Guard to monitor them as they manifest and develop their new abilities.

The sins of a forgotten war still linger, and an ancient evil lurks in the shadows, just waiting for the right time to strike. The Mane Six suddenly find themselves once again at the heart of a conspiracy to bring about Eternal Night, and only by awakening their powers and realizing their full potential can they do anything to stop it. Friends both old and new will help them along the way, and an unseen force will guide them as it seeks to right a wrong made thousands of years ago. The Bearer's journeys will take them outside the borders of Equestria and into the world beyond, and when they return, they'll have the power and experience necessary to save the world and bring about balance in all things.

Cheer up, Twilight. It's not every day somepony changes species. In fact, no pony has ever changed species. It's something new and you like discovering new things. Granted, Equestrians don't like new things, especially things that fundamentally alter their government. So maybe there is reason not to be happy after all.

This story is a sequel to My Little Alicorn

After the events of "My Little Alicorn," everything seemed to be back to normal...except for one pony. Prince Blueblood is now trapped as a colt, his title, possessions and birthright stripped for his crimes. Before Princess Celestia will return him to normal, however, he must prove himself by attending Magic Kindergarten. Even worse, his current situation has attracted the vengeful gaze of two ponies he has offended in the past: the Captain of the Royal Guard and the Moon Princess.

Will Blueblood rise above his past self and emerge a better pony? Or will he sink back into his old depravity, and be stuck a colt for the long term?

Note: This is a sequel to "My Little Alicorn," so you might want to check that out first.

Twilight is beyond the title protege. Prodigies are merely brilliant. Twilight has surpassed most of the greatest mages in history before the age of thirty. Twilight's research has changed the landscape itself. She is a living legend who some whisper may be the greatest user of magic to ever exist... perhaps even an equal one day to the semi-divine princesses.

But Twilight's knowledge is not infinite. She has one final lesson to learn. Twilight must learn the Final Law of Magic.

Twilight Sparkle finds a book in the library.

Twilight Sparkle reads aforementioned book.

Twilight Sparkle's life is thrown upside down, her view of her teacher shattered, and her friends pitted against each other.

Everything will return to normal.

One of these statements is false.
