Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.

This story is a sequel to The Second Pony in Space

Long ago, Starswirl the Bearded created a time travel spell. Nopony has ever traveled through time without the use of that spell. Except for one.

Rainbow Dash has returned to Equestria, and nothing makes sense. She knows the pegasus that visited her, but if Rainbow had been gone for ninety two years, she should be dead. And she knows that purple unicorn, but she should be an alicorn and look different. Her dragon should look different too.

But Nightmare Moon returns, and Rainbow and her new friends need to go obtain the Elements of Harmony to stop her from causing eternal night. But Rainbow doesn't want to send Princess Luna back to the moon again, and needs to show why she represents the Element of Loyalty.

Loyalty isn't always easy for everypony, but maybe Rainbow can make it look like it is...

This is the second story in the Shadow-Dashverse. Reading the previous story is highly recommended to understand what's going on.

This story is a sequel to The First Pony to Time Travel Without a Spell

Rainbow Dash has become an alicorn Princess, but there's still so much that she needs to do. A cutie-mark-removing unicorn, out of control vines that even Discord can't stop, and a power-hungry centaur are just the start. Plus, a certain entity just doesn't seem to leave no matter what...

Starlight Glimmer is Rainbow's friend, and Rainbow gave her a promise. She needs to stop her world's Starlight from going down the same path of revenge as her friend. But it's hard to explain this to somepony that you see in so many different lights. Especially since her world's Starlight doesn't believe in the multiverse.

And Discord is going to be in so much trouble by the time this is all done.

"Twilight, for the third time, I'm sorry I stole your alicorn-ness! ... What do you mean you don't mind? Then why have you been complaining about it?!?"

This is the third story in the Shadow-Dashverse. Reading the previous two stories are highly recommended for better comprehension.

Twilight Sparkle is dead. She died in battle, fighting to preserve the uneasy union on United Equestria between the pony races of old Equestria and the space ponies of Unicornicopia.

But in the wake of Twilight's death, the harmony she strove for has not endured. Using their control of the might armed organisation Starfleet, the Unicornicopian grip upon the land has only gotten tighter. Celestia is isolated, Twilight's friends are scattered, across the stars millions live or die at the whim of the Grand Ruler and his proconsuls.

Project Sentinel is the next step in the evolution of Starfleet, a perfect defence against a hostile universe: clone soldiers created from the DNA of the very best that ponykind has to offer. One such clone, Eve, is a physical copy of Twilight, with enhanced strength and none of the pesky moral qualms that made the real Twilight so annoying for Starfleet to deal with. When Eve, together with a small group of fellow clones, breaks free to search for deeper meaning in her existence, she sets off a chain of events that may allow all of Equestria to break free from tyranny, and all ponies to choose their own destinies once more.

Based on the My Brave Pony: Starfleet Magic universe by Dakari King Mykan, credit to him for most of the OCs

While visiting the earth pony town of Promise, the Great and Powerful Trixie is coerced into searching for a missing foal against her own better judgment. But things are not as straightforward as they first appear. When push comes to shove, what kind of pony is Trixie at heart?

She is Loyalty. She will be the last one standing by her friends, in peril, torture and death.

This is what everyone believes. This is what Twilight and the other Spirits of Harmony, Rainbow's friends, believe. And they took it entirely for granted. After the Mare-do-well incident, Rainbow Dash's Loyalty began to falter. She still felt the terrible sorrow of being deserted by everypony, to be forgotten in the shadow of a greater hero.

Over time sorrow grew to anger. As the powerful bond of friendship crumbles as Rainbow begins to drift away, The others discover just how powerful the Element of Loyalty is, and how its absence might have caused the downfall of the greatest heroes Equestria has ever known.

This story is a sequel to Somebody to Love

The Atlas Strongest Tournament is a tradition which stretches back to the beginning of the history of the Atlantean continent, and this year Princess Luna is officiating the tournament. Rarity receives a visit from her old Spinese master as young Scootaloo enters the tournament. Meanwhile, Darkness is gathering as the Queen of the Changelings begins her own secret plans for revenge against Twilight Sparkle and Ponyville.

What makes somepony evil? How bad can you be before you're too far gone? ... Then again, what makes a hero?

Follow the villains of Equestria in a story of light and darkness that spans a thousand years, in this seemingly unconnected series of events. Seemingly.

Flim and Flam: Past. Welcome, one and all! This, comrads, is an oppertunity! See the famed Flim Flam Brothers as lovable scamps selling their wares and learning the biz.

Trixie: Future. Given an invitation to the Golden Oaks Library, the Great and Powerful Trixie must once again face her biggest and most fearsome rival. Only this time, over tea.

The Shadowbolts: Present. After their celebratory flight show for the Summer Sun Celebration, the Wonderbolts were ready for a good night's sleep. Unfortunately, we know something they don't. This is the night Nightmare Moon was fated to return.

The Diamond Dogs: Past. These mines once contained a proud and fruitful society. Once, that is. These days, a few gems in the wall won't get you too far. The bold and noble leaders of this great mine, Fido, Rover, and Spot, have some explaining to do if they don't want a revolution on their paws.

Ahuitzotl: Past. Every nemesis is only as good as his hero. A.K. Yearling writes a prequel to the Quest for the Sapphire Stone about how she first met the dreaded Ahuitzotl and how they both became who they are today.

Iron Will: Past. Iron Will wasn't always the legendary self-help guru. Once, he was just a little minotaur lost in a maze, trying to find his little brother.

Diamond Tiara: Note: Written before Crusaders of the Lost Mark, it doesn't match up with canon. Past. Once upon a time there lived the King of low, low prices and his daughter, the princess. Also, Randolph, the butler.

Gilda: Present. Griffonstone needs a leader. That much is clear. When the leader of the griffons is called to an international war summit, Gilda, of all griffons finds herself getting invited.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?
