This story is a sequel to The Dresden Fillies: Strange Friends

Almost a year has gone by for Harry Dresden since he left Equestria. He'd have written, but between saving his newly discovered brother and destroying a scourge of vampires he's been a little busy. Then out of the blue he receives a strange letter from Twilight asking him to return. With no cases at the moment he eagerly accepts, but his friends aren't the only ponies expecting him. There's been a lot of rumors since his last visit and some ponies aren't too keen on seeing him come back.

A sequel to The Dresden Fillies: Strange Friends.

Not your typical Doctor Whooves fanfic. A series of events cause the TARDIS to blast into a dimension populated by (you guessed it) ponies and (of course) crashes. While waiting for the TARDIS to repair itself The Doctor runs across a certain brown stallion, whom he will discover is a reflection of himself in more ways than one.

But even after The Doctor was gone his mere presence created a ripple that would awaken an ancient being. Continued in the sequel http://www.fimfiction.net/story/15733/Doctor-Whooves-and-the-Sea-of-Dreams

Rarity's exploits in "Sweet and Elite" set in motion a chain of events that will find the unicorn dressmaker taking part in the greatest airship race in the world, the Alicorn's Cup. Excitement will give way to terror, as Rarity soon finds herself the victim of a plot against Equestria, and shipwrecked far from home with her least favorite stallion, the boorish Prince Blueblood. Rarity will learn of treachery in Canterlot and abroad, and will have search for something of substance beneath the prince's obnoxious veneer as she struggles to not only save herself, but her entire nation.

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...

What if Twilight and Trixie were both zeppelins who were in love? At last this age-old question has been answered!

Twilight has discovered a strange old book purportedly written by Star Swirl the Bearded, and Rainbow Dash discovers a latent spell in it that transports the two ponies to a strange island in the middle of nowhere. With no viable options available to them, Twilight and Rainbow begin to search the island for clues to a way home and the reason behind the odd puzzles and contraptions presented to them.

Dramatic Reading here.

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.

February Write-Off First Place Winner! Commissioned to produce a dress for Princess Celestia herself, Rarity orders in the finest fabric she can get her hooves on. However, her work is disturbed by a mysterious plague that spreads through the town, causing ponies to lose their beloved manes! Is it the work of a phantom prankster? Perhaps a deadly disease? Or maybe something a little more... colourful?

An unfortunate event gives Princess Celestia a fresh view on her life by forcing her to see the world from a very different viewpoint. With Equestria changing around her, she is faced with a personal crisis... if she can ignore how cute a certain lavender unicorn suddenly looks to her.
