This story is a sequel to Teething Problems

Twilight Sparkle has been called to go on a business trip with the two princesses, and takes Spike along with her.

The trials and tribulations of inter-realm travel are not for the faint of heart, as they are about to find out.

Everyone's favorite musical pairing is back in another fanfic! Octavia and Vinyl are now room-mates, and are like any other couple...but how will they react when they discover there's another about to show up?

Twilight Sparkle is summoned to settle a legal matter involving The Great and Powerful Trixie... What in Equestria did she do now?

The Elements of Harmony are defeated and Nightmare Moon stands on Equestria's throne as their new Queen. Is Equestria doomed to suffer through night time eternal or will they be... perfectly fine? Twilight finds her new job as slave or "personal assistant" to her new ruler to be a bit maddening. But is this evil sarcastic queen really as bad as she originally believed? And just how many others are diabolical enough to cash in on the change in staff? Can Nightmare truly run a peaceful Equestria? Let me just answer all these questions right here in the description...

Finding herself with wings and unusually powerful magic, Twilight Sparkle proceeds to have breakdown after breakdown, until with the help of her friends, she confronts Celestia and Luna about it... And learns that she's a far more important little pony than she ever imagined - for all the wrong reasons.

Thanks, man!

This is the story of the end. This is the story of the death of Equestria. It is the story of the reign of her royal majesty, Princess Twilight Sparkle of the Fading Sun.

The alicorn sisters are dead and Equestria has turned to Twilight Sparkle to guide it. However, just maintaining a dim sun a fraction as bright as her mentor's keeps the new princess near her limits.

Years have passed and Twilight Sparkle is sure of only one thing. Equestria is dying.

Vinyl Scratch suddenly becomes a magnet for bad luck and odd situations. After a bad reception of her newest music, she decides to take a break from being a DJ and try to fix her music. But what happens when an not so unfortunate accident involving a sandwich makes the answer more insane than a simple shipping story should be. Watch what happens when worlds collide, the 4th wall is broken, the narrator is extremely handsome, and Muffins may be the answer to everything!

Robert Parker is a 24 year old ex-web developer living in New York city. In the wake of the conversion movement, he has seemingly lost everything. Haunted by the same nightmare every night, he soon realizes that he must make a choice.

To those unfamiliar with the Conversion Bureau: it is a scenario created by an author named blaze in which Ponies either appear in the human world or have lived beside humans without incident for millennia. One day, in the face of all the damage humanity has done to its world, the ponies offer a solution: undergo conversion to become a pony and allow the world to be inundated with Equestria's influence: thus healing it and bring forth a golden age.

Many different authors have taken many different approaches to this idea, all of them are worth checking out.

At first glance, Princess Luna's charioteers might appear to be little more than Royal Guards dressed in festive apparel for Nightmare Night. However, there is far more to the story than that - the Night Guards once played a pivotal role in the history of Equestria, and have sacrificed more for their beloved princess than most ponies are even aware of.

The legends told of their return.

For over a decade Equestria has been beset by the dragons. Every year more villages vanish in flames, and the lonely cities stand as our last redoubt. Winter has gripped the world, and our hope is fading.

But the legends tell of another, a light in the darkness. The Dragonborn, a mythic warrior reborn with the power of the Voice, the only one who can stand against the dragons.

But when she appeared, she was not what we were expecting...
