Canterlot lies steeped in chaos, a virulent and deadly plague still boiling away after a decade of suffering. The city, and the ponies in it, still feel the effects, still feel the bite of the times. The lower city, cursed as it is, is mostly partitioned off, leaving each and every pony left stranded and without help. Ponies struggle day by day just to stay alive.

Even as the ponies suffer, politicians toil away, plotting and scheming, machinations rumbling just below the surface. The city is fevered, sick and bloated, ready to pop at any moment. A single pony may be enough to make it all erupt.

And make it erupt Twilight Sparkle shall.

One small step, one lucky break is all she needs to turn the city on its head and take her rightful place by the Queen's side. But even she may not be prepared for the shark tank that is Luna's court.

It has been more than one hundred years since Celestia banished Nightmare Moon. While Equestria has enjoyed a century of relative peace and prosperity, there are still lingering tensions between the three pony tribes.

Shadow Kicker, a proud warrior of Pegasopolis, must navigate the treacherous noble court of Canterlot and address the concerns and wounded pride of her own tribe in a desperate effort to prevent matters from coming to open warfare.

Steel Song is a lot of things. Earth pony. Uncle. Professional bodyguard.

Retired.

So when he receives a mysterious package from Princess Luna a few weeks after the changeling invasion, he's understandably apprehensive. More-so when he presents himself before the Royal Diarchs to find that not only do they desire him to come out of retirement, but to take command of a most unusual position...

A position that may have more significance than any of them suspect. Because strange thefts are occurring on the Equestrian Railway, thefts that nopony can explain. Thefts that may have far more sinister intentions than their seemingly innocent nature may convey.

Intentions sinister enough to shift the balance of power in Equestria forever.

"In the pegasus empire of Cirra, the quinquennial census of the population was incredibly important to taking stock of the resources of the empire. Two thousand years after Cirra's fall, the records kept by the censors offer an illuminating glimpse into what life was like for the pegasi and griffons in those ancient times. I have translated the personal records kept by one such censor, Aureus Primus, taken during the height of Cirran power in the Diodan continent. I present them here for you to read and learn more about this fascinating pegasus empire that we know so little about."

Supplementary work to Of Skies Long Forgotten. It is strongly recommended that you take the time to read that story first before reading this one, as this story focuses more on the worldbuilding of the setting explored there, and contains some spoilers to the plot of that story as well.

Part of the Price of Loyalty storyverse.

At first glance, Princess Luna's charioteers might appear to be little more than Royal Guards dressed in festive apparel for Nightmare Night. However, there is far more to the story than that - the Night Guards once played a pivotal role in the history of Equestria, and have sacrificed more for their beloved princess than most ponies are even aware of.

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.

The Shaper is a smith of unparalleled skill, her creations the most sought after in the fallen world. When a pony named Lyra comes to her with a unique commission she has to put all her skill to the test to craft a weapon of great power. For Lyra's goal is not an easy one, and it is not just any weapon that can kill a Dragon.

A story inspired by this and this image, as well as this challenge by CDRW (whose fic A Still More Glorious Dawn Awaits is quite good).

Blank Slate is the greatest thief of his generation. He has robbed countless nigh-impossible marks, and his talents as a master of disguise are beyond par - truly, nopony knows who he is.

And now he's preparing the greatest heist in mortal memory: the treasure vaults of the Princesses themselves.

But you have to get up pretty early in the morning to get one past the pony who defines when ‘early in the morning’ is…

This story is a sequel to Memories Don't Burn

The library is gone. Princess Twilight Sparkle has a new home...one that needs a lot of work.

She also has a lot of questions. Questions about her new role in Equestria, the part her friends will play in it...and whether or not she should assume rulership over Ponyville.

This is a sequel to Memories Don't Burn, but also an interquel, as it expands upon events between that story's first and last scenes.
