The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

The sequel is here: The Twilight Enigma

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

Twilight had planned to visit Sunset Shimmer and her friends over in the other world for a nice, quiet weekend, away from all the worries and problems associated with being a Princess of Equestria. Unfortunately, things rarely go as planned.

After an accident cuts her off from Equestria, Twilight finds herself stuck in the human world until the gateway between the two worlds can be fixed. Which wouldn't normally be a problem...

...If she wasn't still a pony.

Now with TvTropes page!

Proofread by Dusty Old Qrow, RQK, Dusty Tomes (Ch. 2), Emtu, and Doctor Candor.

Princess Cadence is a foalsitter who, being in rich, hoity-toity Canterlot, has to put up with spoiled brat after spoiled brat.

Twilight Sparkle is a terrifying filly who drives away sitter after sitter.

They were bound to find each other.

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.
Also has a TvTropes page: Split Second Tropes.

This story is a sequel to Stormsinger

In wake of the assault on Starfall, Serale Everstar has agreed to her mother's wishes, and will travel the length of Equestria to pay respects to her mother's rival Courts. But burgeoning magical ability and the possibility of traitors around every corner have placed on the young Lady more stress than she could hope to bear alone.

Apprenticed to the Court Mage, Cobblestone, recently a cutpurse and recovering addict, is eager to begin her training in the arcane arts. But her own abilities have attracted the attention of old powers, not all of them with her best interests at heart.

Tasked with protecting his Lady at the cost of his honor, Vino Hedera is young and untested in the field of battle and the art of command. But all is not as it seems among his compatriots, and the greatest danger he faces may well come from within the ranks of those he should be able to trust with his life.

With the forces of the Shadow gathering, pursued by forces both foul and Fae, and unsure of who to turn to, these three ponies may have only each other to rely upon in the face of the most terrible enemy Equestria has ever known. It falls to them to prepare for oncoming war, one in which the stars may shake and the sun itself may fall from the sky.

Book Four of the Sunfall Saga. Book Three to be found here.

Unwilling to sleep in his own boring and less-than-comfortable bed, Spike presents Twilight with a deep and compelling argument as to why she should be his bed for the night.

TwiSpike cuddle time abounds...

Everypony enjoys myths and ponytales, even if they know such things aren't real. Alicorns fighting against a spirit of chaos? An ancient princess trapped in a library under a tree, waiting to be found? Quite enchanting and fantastic tales yes, but nonetheless as fictional as Daring Do and other such stories. At least, that's what Rarity used to think.

She doesn't anymore.

Dedicated to Annuska for being as amazing a writer as she is a friend.

Ten years ago, the Griffon Empire opened a portal to a strange new world and tried to annex it. In the peace settlement that followed they lost control of the province containing the portal. Since then, the Griffonian Democratic Republic had been completely isolated, surrounded on all sides by a hostile empire. Now, for the first time, a visitor had been allowed.
