This story is a sequel to the From the Shadows comic arc (51-53).

Shadowlock and Twilight parted on good terms, after a few clashes. But when he shows up again, asking for help in undoing the damage he caused, the two of them embark on an adventure that will change both their lives.

Immense thanks to Triq267 for prereading and consultation, as well as to the wonderful folks at /mlp/, where I posted the rough draft.

Note: I commissioned the cover art from PrinCrim.

Twilight Sparkle's Harmony Project is the culmination of her life's work. The only thing left is for everyone to be gathered, so that all of Equestria can join together in Harmony.

But now that success is staring her in the face, Twilight begins to have doubts. Fortunately, she has a friend like Discord, who is only too happy to lend a paw to a friend in need...

"Beware Her wrath, fools who dare threaten our Kingdom. For if Celestia be our Shield, then Luna is the Sword."

Spiritual companion to Sweet Celestia.

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.

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

Plowpony's Day- a day of peaceful rest and relaxation. Or it was, until Twilight Sparkle badly mangled a teleportation spell. It has left her with a bad case of Horn Rot, a disease that if untreated could prove fatal. What's more, the malady is advancing faster than the slow-brewing potion that cures it!

There is one swifter cure: the Beneviolet, a star-shaped flower that grows in the distant Archback Mountains, far beyond the western borders of Equestria. Applejack, Rainbow Dash, and Rarity choose to undertake the long journey for the sake of their friend. Their path will wind through floes of ice, across gold-tinted plains, into distant forests glimmering with magic. They will learn much about the world beyond their homeland- and much about themselves, as well.

Yes, it's "Dangerous Business," here on FIMFiction. A huge debt is owed to all those who have supported me over the years. I've edited the story some to remove extraneous bolding and italics, but other than that, it remains unchanged. I hope new readers enjoy it as much as old ones did.

Hope is the faith of the young. Losing everything she holds dear, Puppysmiles embarks on the adventure of her life to find her mother, her hopes of meeting her again driving her through the horrors of a world not of her making. Too bad the Wastelands doesn't care about hope.

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

When Balefire baptised all of Equestria, life itself was nearly extinguished. As the dust settled, little was left save for shattered ruins and broken hopes, shadowed beneath a cloud-filled sky, the survivors crawling from their shelters to eke out a meager existence amid the remnants of the past.

It was far above the surface that last shreds of Civilization held firm. The pegasus ponies, whose capitol of Cloudsdale was obliterated in the Last Day’s first strike, closed off the sky in grief. Proclaiming the surface lost to it’s fiery fate, they turned their backs on the surface world. Anypony who defied the new Council’s ruling would be branded as an outcast forever, and cast down to the hellscape below to die.

It was here that the greatest minds and strongest warriors the pegasi could produce gathered for their greatest undertaking yet... A great return; a new war nearly two-hundred years after the first.

Even as the dust settled and corpses cooled far below, the pegasi turned back to a culture of war... Just as in the days of old, ponies divided themselves and fell to chaos, distrust, and discord.

This fic will be a starting point for stories to come, and is also a prequel to a work-in-progress piece entitled 'Fallout Equestria: Finding Harmony' by RedSquirell456 (the author of My Little Metro and Whisper Sun, Silent Moonamong others) that will feature some familiar faces.

Applejack and Twilight are called by the cutie map to Ponyville, oddly enough, but face some technical difficulties.
Twilight then decides she's hungry for a hayburger.

Deep in the Royal Library is a book. A terrible book that is said to send whoever reads it mad. A book so dangerous that it has to be hidden away and secured with chains to prevent it from ever being opened.

A book which has just been accidently checked out by Spike on behalf of Twilight Sparkle.

The Star In Yellow is rising once more, and only Rainbow Dash and Spike can save Twilight before it's too late. Ideas live forever. Ponies do not.

This fic is loosely inspired by the 19th century story 'The King In Yellow'.
