This story is a sequel to Days of Wasp and Spider

Believed dead by their creators, the ponies that will become Celestia and Luna have broken their mental conditioning and escaped into the wilderness. Here they plan the revolution that will free all ponykind, knowing that it is only a matter of time before their ruse is discovered.

Back in their underground arcologies, the ponies' erstwhile masters deal with the consequences of the escape, all the while unaware that something lurking at the bottom of space-time wants them all dead.

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

Crossover with the Dresden Files. Sequel to Forever!

For his first task as the new Winter Knight, Harry must travel to the land of cute little cartoon ponies to stop a plot by the Order of Blackened Denarius that threatens both Earth and Equestria.

Warning: Includes massive spoilers for the Dresden Files series up through Ghost Story.

Ten years is a long time, so Sunset Shimmer thinks. Ten years since she was last a pony. Ten years since she started her life anew as a citizen of Canterlot City. Ten years since making a group of wonderful friends. Ten years of absence from Equestria.

She's perfectly fine with that absence continuing for many years to come.

Twilight Sparkle doesn't appreciate Sunset's reluctance to talk about the past. She's been studying the strange activities surrounding Shimmer since they were teenagers, and has only found further questions. But a murder with ties to Equestria gives Twilight the chance to learn the truth about magic. To stop a terrible enemy from rising again, they must both journey through the mirror. Enlightenment is at Twilight's fingertips.

She doesn't quite know what to think when she meets Princess Twilight Sparkle.

Written before Friendship Games was released.

Celestia is not invincible. Strong, yes. Ageless, assuredly. Magical, undoubtedly. But not invincible.

The Princess of the Day has been attacked, and she did not escape unscathed.

While Luna fights against the mortal fear gripping her subjects in the wake of the assassination attempt, the enemy runs free. Twilight Sparkle must assemble a team to bring the pony to justice. Few ponies can be trusted, and fewer still can be expected to succeed.

But the kingdom has heroes: The Knights of Harmony. Ponies who have stood against evil and won, who fight to make Equestria a safer place. Each is an expert in their particular field, masters of their trades, but they have yet to work together.

An adventurer past her prime.

A tinkerer with too much time on his hooves.

A spy whose primary instinct is to lie.

A dishonored soldier with an axe to grind.

As they delve into the origins of the assassin, they find that Equestrian history still has secrets long buried. Can the knights come together as a team before she finds her next mark?

In the warmth of her cloud home, Rainbow Dash is about to turn in for the night when she hears Scootaloo crying outside in the middle of a vicious blizzard. Plucking the freezing filly from the snow, Rainbow hopes to provide some much-needed comfort for the otherwise tough young pegasus, but she uncovers a disturbing reality that she knows she cannot handle alone.

Knowing only one pony that could really help her out, Rainbow enlists Twilight’s help, determined to set things straight for Scootaloo. But what Rainbow doesn’t know is that in her efforts to provide a better life for the filly, her friendship with Twilight will develop into something more.

Today, I will tell you the story of the lost book of prophecies...

Overnight, the Void awoke, threatening to destroy all worlds. Once again, Twilight was chosen to be the savior, this time by traveling the multiverse to rescue it from an untimely demise. The journey will be long, come with many friends, several enemies, and test her like nothing else ever has. Each world has its own rules, its own ways—but all are in danger from the nihilistic desire of a cackling Count.

A reimagining of Super Paper Mario with ponies and a few twists. Every world Twilight visits will be a new crossover, and part of the way this story is structured is to encourage readers to guess what worlds are going to appear. No familiarity with any franchise is required to read the story, as is tradition with my crossovers.

Read this spoiler only if you want to know the surprise crossovers ahead of time. Updates whenever a new franchise is revealed:
Contains MLP, Super Paper Mario, Avatar: The Last Airbender, Sonic X, Star Trek: The Next Generation, The Chronicles of Narnia, Mario in general, Warhammer Fantasy, Numenera, and Final Fantasy
