This story is a sequel to A Stitch in Time

Having discovered the message left for her by Star Swirl the Bearded in the distant past, Twilight once again finds herself caught up in the middle of a struggle against forces far greater than herself. In order to even stand a chance she'll need to travel further and wider than she ever has, and forge some unlikely alliances with old enemies. All to bring down the powers that have manipulated and shaped her entire life, and retake control of her own future.

After the events of Hard Reset Twilight's life and mental well being are slowly returning to normal. Her recovery is cut short, though, when a letter arrives informing her that the time loop spell she cast is causing severe damage to space and time itself. In over her head, Twilight tries to summon anypony who will know how to fix it. The pony she gets is the last one she ever thought she would meet... and nothing like she expected him to be.

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.

Over a thousand years ago, two royal siblings fought for the sky and were exiled, one by her sister's hoof, and one in penance for what she had done.

In the present Republic of Equestria, no one remembers them as anything more than legends and old pony tales. Save for one shy filly who fell from the sky one fine summer's day.

An Alternate Universe "What If" tale, reconstructing the beginning from a different angle.

From the mind of Lapis-Lazuli...

When Dinky Doo finds something unexpected under her bed, she decides to find out what put it there.

(With thanks to Carmine from the FimFiction IRC for inspiring this story.)

A Diamond Dog king, feeling bold after gathering an army of 100,000 dogs, decides the best way to flex his new muscles would be to invade Equestria for past perceived slights. As such, he sends a letter to Princess Celestia with a declaration of war.

It goes about as well as you'd expect.

A troubled Princess Celestia, wandering her School for Gifted Unicorns late one night, chances upon her young faithful student Twilight Sparkle, who has problems of her own:

She can't catch the Tooth Flutterpony.

What possible advice could Princess Celestia give to her upset young pupil, who is desperately trying to prove that an old ponies' tale is real?

Inspired by Skywriter's How to Remove a Unicorn Tooth (which is a much better story and you should probably go read it, if you already haven't); and, of course, Sir Terry Pratchett's Hogfather (which you should have already read, and even if you have, you should go read it again).

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

Now with its own TV Tropes page

There is now a follow-up to this story: Sunflower - Side Projects
Sequel: Project Sunflower: Harmony

Shawn Spencer, psychic detective, is a thick-tufted boy genius who ice skates through life on polished blades of snarky eloquence. He has tested himself against some of the greatest criminal minds of his time and emerged victorious... though often through unbelievable luck and not a small amount of bumbling.

Now, he faces a challenge unlike any before. One that will test his mind, his sanity, and his adaptability as he is thrust into the midst of an unfamiliar world and the ponies who populate it.

The Mane 6 face their own challenge, as an old enemy, tempered in the crimes of a much harsher world than theirs, returns to Equestria. It is a challenge they are ill-prepared for and one that only their strange, new, alien friend can help them overcome.

There may be spoilers in the comments. You've been warned.

For their first home together, Twilight and Applejack wanted a house close to Applejack's farm and big enough for Twilight's books, with a little something special besides. They settled on the perfect place, one of the oldest barns on Sweet Apple Acres, and had it converted into a comfortable house for their little family. But when strange things start happening just after they move in, Twilight finds that she has a mystery to solve before she can really call her dream house "home."
