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.

This story is a sequel to Dusk's Dangerous Game

Twilight Sparkle, known to all but the three Goddesses as Lady Everstar, the Evening Sage, has ruled over her kingdom for nearly five centuries with all the wisdom and grace of which she is capable. Her lands are wild and exciting, the prospects good for those with brilliant minds and daring hearts. But now something has changed in the Evening Kingdom, something has changed the balance of power so profoundly that even Twilight herself cannot tell how events may unfold.

Across the ocean, an ancient evil is stirring, its dark hunger can finally be realized. Its servants are many, brutal, and cunning. They are found among the lowest of lows, and the highest of highs. With the balance of power so disrupted, it is at last time for their shadowy plans to come to fruition, to cast off the darkness and strike against the night.

It will take the power of goddesses, magic both familiar and ancient, and the most unlikely of heroes to save not only the Evening Kingdom, not only Equestria, but the entirety of Creation as we know it.

Sequel to Lines and Webs and Dusk's Dangerous Game. Knowledge of the previous stories is not needed, but reading them is, of course, encouraged.

Followed by Courts of The Magi.

This story is a sequel to Lines and Webs

For four long years, Celestia's apprentice Twilight Sparkle, once a model pony and a hero among heroes, has waged a bitter and secret struggle with her onetime mentor. Though she works from the shadows, directing her forces from the Old Capitol in the Everfree Forest, Twilight Sparkle is unable to gain any advantage,

Likewise, Princess Celestia finds her once-faithful student far more cunning and elusive than she had anticipated, and even now searches for a way to bring Twilight Sparkle's rebellion to its knees.

It is a game of greys, of knives in the dark and of poisoned wine, where pawns are moved and traded and exchanged for greater advantage, all the while drawing both sides nearer to the conflict which shall tear Equestria in two.

At the center of this conflict is a new pawn, one who only wished to see the truth for herself. Drawn into a deadly game whose rules she does not understand, Sweetie Belle must learn to survive in a world where all is darkened, and nopony can be completely trusted.

Because when gods play chess, all pieces are expendable.

A nation will crumble, old enemies shall return in the most unexpected ways, and regardless of who is victorious, only one thing can be certain.

Nothing shall ever be the same.

Followed by Stormsinger.

It has been ten years since the defeat of the Changling Queen, and Equestria is again at peace. Twilight Sparkle and the Elements of Harmony have reached their prime, and have begun to settle down. Love and life abound in Ponyville, especially for Twilight's friends, but she has nopony to call her own.

There is a reason.

A series of events lead to a horrible revelation, and Twilight is thrust deep into a terrifying web of secrets and lies. Her peace is over.

This time, however, she won't be fighting monsters or madponies. What she faces will be much, much worse.

Act One of Two.

Act Two is here.

Currently undergoing editing by the wonderful Mstar!

For as long as the oldest of them could remember, the Guardians had defended what remains of humanity against the forces lurking in the dark. With gun, blade and the Traveller's Light, the heroes born of Earth put themselves between the monsters from the void and those too weak to fight back. Human, Awoken, Exo; the physical coil of the Guardian had never truly mattered so long as they were willing and capable of defend their homeworld.

Until a Guardian came from the wastes that was neither Human, Awoken or Exo; a Guardian not born of Earth.

This story is a sequel to Celestia

Villains rarely appear out of thin air. They start as most creatures do, but fall victim to fate, choice, manipulation... or love. Princess Luna's descent into the Nightmare is something that has been long forgotten by modern ponies, but Luna will always remember.

(Sequel to Celestia, and a part of the past that she would rather keep hidden. Reading Celestia is strongly recommended!)

This story is a sequel to Inexcusable

She looked just like Princess Celestia, except marred and broken. Her ceremonial barding had rusted slightly, and dirt matted her coat. Most noticeable was her hair; black streaks accompanied its usual multicolored luster. They looked like discolorations in an old photograph.

Worst was the scar across her chest. Her armor covered it, but nothing could hide what it meant.

The tarnished Celestia smiled at Luna. "H-hello, monster. I would say I am glad to see you, but that w-w-wouldn’t be quite accurate."

This story is a sequel to If You Came to Conquer

Princess Nightmare Moon had tried to keep it secret. She had suppressed her power, feigned ignorance, played the outdated fool at every opportunity. She should have known that something like this would happen. A threat that would reveal her, whether she played dumb or not.

If she had to reveal herself, then at least she could protect Equestria in the process. She nocked the arrow. The bow felt so flimsy, but she could not risk him absorbing a spell. She laced magic across the arrow and the string and the air, enough to make it fly faster and aim smoother. She sighted him easily; Tirek was a large target. Now he only had to turn around. An arrow to the spine would kill him simply and instantly, no matter how much magic he had absorbed.

Once he was dead, the hard part would come: explaining herself to Celestia.

Nightmare Moon won. She defeated Celestia, broke the Elements, banished the sun. This all happened a very long time ago. So long ago, that she has had plenty of time to change her mind.

Of course, fixing our mistakes is never so simple, and never without consequences. Even with particularly potent help.

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!)
