This story is a sequel to Stardust

Everyone knows the story of Hearths Warming Eve. They know the tales of the three pony tribes and how their strife brought the Windigoes upon them, and how the Fires of Friendship saved them from their frozen fates. For countless generations the tale has been told, but how has it changed over those years?

Or is any of it true in the first place?

Only one pony knows, and Celestia would prefer that the past stay forgotten.

(Based on a 'What If' line of thought that was born from the Stardust storyline. While some familiarity with Stardust and Mente Materia doesn't hurt, this story can be enjoyed on its own)
(Coverart available soon from the amazing FoxInShadow!)
(Many thanks to Arzoo, BradTheBrony, Vandenbz, and Setokaiva for prereading!)
(Complete with it's own TVTropes page as part of the Stardust continuity)
(Character tags will be added as chapters are added!)
(Possible spoilers in the comments! BEWARE!)

Equestria is still picking up the pieces after the defeat of Tirek, and everypony is helping out with the paperwork, even Rainbow Dash. Things change when Princess Celestia arrives, bringing with her a letter with some very stunning accusations of the exploits of a resident in the town of Oasis. Now, the main six are tasked with finding out if the letter was truth or fiction. Did this Mister Baker really do what they claim? Only one way to find out.

However, Mister Baker is not who, or what they expected.

Rated Teen for occasional language. Additional tags added for more dark themes.

Proof read and edited by the amazing SunnyPack , Snakeskin Ducktape, and Tyrannosaurus Tux.

No pony can slay the King. It's Nopony's destiny to do so. But when you cheat fate, fate cheats you.

Alternate Universe tag because here, King Sombra won when the Crystal Empire returned. He has been ruthlessly ruling Equestria and beyond ever since.
Proofreading by Smaug the golden.

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.

Tirek. Discord. The Changelings.

The ponies have faced all these threats, and triumphed, but things could have been handled better. Princess Celestia knows this better than most. She knows that to face threats even greater than Tirek, greater than Discord, the ponies need allies. They need friends to turn to when the chips are down and the mad gods and cruel tyrants are on the horizon

She and Princess Twilight Sparkle travel to the Griffon Kingdom to meet the Griffon King. They seek to negotiate a formal treaty, something more than a rudimentary "You stay in your yard, we'll stay in ours." If the Changelings invade, or Tirek is once more a threat, it will not only be the ponies standing against them, but the griffons as well. It's only logical, after all. The griffons and the ponies share a border. They share ideas. They share refugees and concepts and cultures. And there haven’t been any major hostilities since the Pony-Griffon War. That was almost a thousand years ago.

It is logical to enter an alliance, but politics aren’t always about logic. Sometimes they are about past crimes, mistakes, and tragedies. Sometimes, past grudges simply can't be let go.

(Rated Dark and Teen for some disturbing content, though nothing too heavy or overt)

Coverart from Pie on furAffinity

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.

It has been one of the closest guarded secrets of Canterlot's royalty. Deep in a specially constructed dungeon, surrounded by warding spells and powerful magic barriers, exists an enigma. Within a cage that could only be described as something out of a nightmare, it waits and watches all of Equestria. A creature that cannot age, is immune to disease, does not thirst nor hunger, and resists all injury. But, it also holds secrets and knowledge that could safeguard the kingdom. Its powers are frightening, but it is civil enough for debate when patience permits.

Princess Celestia has sought counsel with the creature before, enduring it making deal after deal for its services. The Princess walks a fine line when dealing with it, knowing full well anything could give it an advantage despite its imprisonment. She has had to go back on her word in these dealings, and from this a deep animosity between them has been born. It is a necessary evil as she is convinced this is a being capable of untold evil far and above anything Equestria has ever dreamed of. So long as it remains within the confines of its cell, her kingdom is made safe. So much magic has been woven to ensure that, there is little chance of escape.

So long as the magic holds, there is no danger. So long as the cage remains strong, the nameless creature stays enthralled in his cavernous dwelling. If that were to change--if the magic failed--not even the wisest could say. But one thing is assured, it does not bode well for Equestria.

This story is a sequel to Ponies, Pirates and Peculiar Psychopaths

Chrysalis has been driven out of Canterlot, her invasion defeated. However, an old friend from her time before becoming queen is more than happy to help her succeed with her plans.

Will these two achieve their goals, conquering pony-kind and ruling over them with iron fist and hoof? Or will they be stopped in time, preserving the peace that Equestrian has known for as long as can be remembered? There is more than just dreams of world domination at work, though, this is personal for Chrysalis and her rediscovered assistance.

Hopefully, the line that 'Evil never triumphs' will prove to be correct, or else a drastic change is going to descend upon not just Equestria, but the entire world.

Thanks to Avatar of Madness for the coverart.

After a tragic accident, a human ends up in Lord Tirek's body, as part of an attempt to reform the villain after his recent escapades. While the hero of our tale is trying to make sense of his new surroundings, the rest of Equestria thinks that the most terrible threat that their world has ever seen is back...
And the powers that be are definitely not happy about it.

There are a number of compounds the human body is incapable of synthesizing; these are found only in red meat. To save a dying human, Twilight asks her friends - except for Fluttershy - for advice.
