First of the Savage Skies series.
After running afoul of timberwolves in the Everfree Forest, Fluttershy is saved by a mysterious young colt with a most unusual and disturbing feature. Realizing that he is alone, without anyone else to care for him, Fluttershy realizes that she must try to bring this lonely foal out of the forest and give him a life of love and friendship. The problem is that this colt's...unique qualities have made him more than a few enemies, including some who are closer to home than Fluttershy realizes.

Now with a sequel: The Promise of a New Day.
Now with a TV Tropes page.

On a midnight train, one mare travels to Canterlot. She goes to see Princess Luna, presiding in her Night Court. With her, she carries determination and a book. The book has been passed from parent to foal, from generation to generation for a time longer than most ponies can even imagine.

She travels to Canterlot to give the book to Luna.

And neither pony will be the same after.

Inspired by the exquisite fan work: Children of the Night.

A drama couch is important business. Much like a wedding dress for a princess, It must be tailored specifically to the pony that will use it. Rarity finally faces that dreaded day when she must find a suitable replacement to one of her most treasured possessions.

Twilight Sparkle is trying to run away. But Sunset Shimmer needs her in order to help her best friend.

She'll do whatever it takes, even if it means submitting to the darkness once more.

Once upon a time, in the magical land of Equestria...

One week ago, Twilight Sparkle was crowned the fourth Princess of Equestria. Tonight, Ponyville hosts the 1003rd Summer Sun Celebration, and Princess Celestia and Princess Luna want a vacation. With two fine young princesses like Cadance and Twilight to take over for them, nothing could possibly go wrong.

Idol Hooves holds a special place in Equestria. He's probably the only exiled changeling to serve in the Royal Guard, or at least, that's what he expects, as exiles don't really broadcast that fact. However, it's well known that Princess Celestia loves all of her little ponies, and her guards perhaps more so, and that makes it one of the best ways for a changeling to discreetly feed.

But how does a changeling even get there, let alone get exiled in the first place? For that matter, why would it ever go to Canterlot? Set a number of years before the series proper, before Luna’s redemption, Idol details how he was exiled, the ponies he’s met, and the series of misadventures that led him to joining the Royal Guard, and should continue a good ways into the series, as something of an alternate perspective.

Soon, he’ll have to deal with a boisterous new princess to serve and a royal wedding in the works bringing a third to power. Will his old instincts bring this new life crashing down around him? What precipitates Chrysalis’s ill-fated assault on Canterlot? Is it really so wrong for a changeling to enjoy good craftsmanship to an obsessive degree?

"Twilight isn't exactly a social pony." Could win me the Understatement of the Year award.

However, what most ponies don't know is that Octavia, a high-class socialite, isn't exactly much better herself, despite countless rumours about a liason between her and a certain DJ.

Now, drawn back to the upper-classes that she tried so desperately to get away from, can Twilight Sparkle find solace, and companionship, from one of the very socialite ponies of her past that she is so desperate to escape?

This story is a sequel to Syncopation

Vinyl Scratch and Octavia Philharmonica. There's nopony in all of Equestria that doesn't know these names. They are the pinnacles of their genres and the peaks of every genre in between, but it wasn't always this way.

When they first met, Octavia was fresh out of the Canterlot Conservatory and Vinyl was the only member of Syncopated Records, a new music company created by Fancy Pants and his wife Fleur de Lis. They have grown since then, overcome trials both as individuals and as a company, but Fancy Pants still has greater plans for his company. Plans to expand, to become bigger names, to be known not only in Canterlot, but in all of Equestria! In order to do this, the musicians of Syncopated Records, Vinyl, Octavia, Harpo Parish Nadermane, and Lyra Heartstrings will travel through the princessdom, playing their songs and trying to make their own mark in music.

But it will be difficult. They'll have to be more than a company and more than a music group. They'll have to work together, getting used to their off-beat attitudes until they can work as one.

Syncopation must meet with Synchronization.

A head full of romance is what many Canterlot ponies would call a frivolous waste of time. Everypony was meant to play by the rules of high society: keep your nose in the air, laugh at important ponies' jokes, and attend all of the right parties. Upper Crust and Jet Set had been diligent in raising their daughter Crystal Wishes to be a pony everypony would know, but she wanted more out of life than that. She hoped she would someday meet a handsome prince and fall in love, just like in the stories she wrote.

Crystal knew life wasn't as easy as a foal's tale, but that didn't stop her from dreaming. All of the wishes, hopes, and dreams inside her heart escaped into her precious notebook as she wrote about princesses in power and dashing knights. So long as nopony found out her secret, she could continue to play the part of a dutiful daughter while waiting for her own love story to begin.

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?
