A violent, unexpected thunderstorm wakes Rainbow up in the middle of the night. Unable to do anything about the storm but unable to sleep, she has nothing to do except lay in bed and think. Ponies, Ponyville, her job, her friends, and the differences between Loyalty and Honesty - not all of them always make sense.
A short swim through Rainbow Dash's stream of consciousness.

Rated ‘Teen’ for language.

It's been a thousand years. Princess Luna is returned, and the castle staff must scramble to see that she has servants to attend to her needs, and just as importantly, that they look the part. Of course, it turns out that it's rather difficult to find competent servants on such short notice. A hooffull of servants are chosen based on their appearance and duties, and are assigned to serve the Moon Goddess as personal retainers until more suitable replacements can be found. When coloring, Cutie Mark, and chance coincide, one of the castle's junior stewards is thrust into a role any loyal servant ought to jump at: Lunar Hoofservant. Unfortunately for Nightlight, Princess Luna is far more demanding than her older sister, and being her servant means contending with an unforgiving goddess who demands nothing short of perfection. Furthermore, somepony must be responsible for the inevitable failure. The duty of "Royal Hoofservant" just might be synonymous with "Royal Scapegoat."
Saddled with responsibility far beyond his post and expected to fail, Nightlight has no choice but to quit his post or to become the servant that Luna needs. This is the story of a pony's development from colt to stallion, and from servant to leader.
Thanks much to DirePony for the editing and story direction he's graciously provided me.
Rated 'Teen' for alcohol use, mild innuendo/sexual references, and pony-swears.
Not based on the (excellent) sci-fi novel of the same name by Robert Heinlein.

Some Canterlot entertainers aren't just musicians... and some ponies fall in love with them anyways.

When one of Equestria's most popular cellists appears at Twilight's birthday party, it's just another gig for Octavia, but a shock for Twilight and the rest of the party-goers. She arrives, wishes Twilight a happy birthday, wows them with her beautiful music, wows them with her musical beauty, and doesn't leave until after everypony else has left. So when a few ponies suggest that this 'entertainer' might be more than just a musician... some eyebrows are raised, but nothing more. Twilight is beyond reproach, after all, and Octavia can earn her living however she wants. When she sticks around Ponyville, however, it becomes a slightly different story - Twilight is romantically-naive, after all, and Octavia is... most certainly not.

The romance of Twilight Sparkle, Celestia's protege, and Octavia van Clef, Canterlot's most famous entertainer.

Rated 'Teen'. Per FimFiction's rating guidelines, this story contains some 'more adult themes', but has no 'graphically adult content'. Rated primarily for sexually suggestive material, but also (in later chapters) alcohol use and adult language.

Dearest Billy,

It is with a heavy hand that I must relay: He is dead, and passed away among his bees only some hours ago. I, too, am not long of this earth, thus it falls to you to publish my final wish. The attached parcel is my tin box--you have ferried it hither and thither before--and it is where notes from all our adventures, spanning two centuries, as many wars and three monarchs had been safely kept. The remaining bundles within, however, we agreed some time ago to never publish, lest our reputations be shredded. However, with his passing heavy on my mind, I cannot forget such cases, so singular and impressive that they prove, without a doubt, that Sherlock Holmes was the greatest detective London, Britannia, and Worlds beyond our farthest imaginations could ever have known.These cases will confuse you--perhaps even tarnish your memories of us--but mark my words: they are as true and real as the paper upon which you read this letter.

Most Faithfully,
Dr John. H. Watson MD

Hearth's Warming has always been a time for family and friends. A time when the ponies of Equis remember the frigid days before the rise of Modern Equestria, and bask in the warmth and comfort of their loved ones.

But for one particular holiday season, strange things are happening in Ponyville that can’t be easily explained. Least of all by Scootaloo, who is having her own share of troubles during this normally festive time of year.

When the mirth and whimsy of Hearth’s Warming starts to take on a more dour and icy edge, things take a turn for the stranger when out of the blue, the enigmatic “Doctor Clockwork” appears.

Join the Hourglass Stallion as he takes it upon himself, his temporary companion Spike, and the newly-conscripted Scootaloo to save Hearth’s Warming before the holidays are ruined forever!
