This is the story of a brony, who inserted into Equestria.
But instead of a pony, he became the enemy of Celestia.

Would he decide to do what’s right, to love and tolerate
Or would his evil changeling nature make it hard to integrate

Then there is the question of the duty that is his natural birthright
Tasked by the changeling Queen, he was to murder Princess Twilight

So, here’s my attempt at a SI with a bit of a twist that others have done before. Go to Equestria, end up on the wrong side of the tracks, and have to deal with it. Enjoy!

Long ago, a terrible monster known as Ninetails unleashed a reign of destruction upon a distant land before being defeated by holy priests. While helping the land recover and purifying monsters, a fox they had in their care spawned a second tail. Despite knowing the risks, the priests believed she could be a force for good and began to train her in the ways of healing and purification. 

However, not long after gaining her third tail, word of her existence began to spread, causing her caretakers to fear for her life. They decided to send her to a distant land, a land of peace, harmony, and friendship. There, Princess Celestia found her and, interested in her ability to purify monsters, took the three-tailed fox in with the hopes she could save her fallen sister.

"Will she find acceptance and happiness among ponies? Will she save Luna? One thing is certain, her race's heritage and instincts won’t make it easy."

This story starts 50 years before Nightmare Moon Return. Humans make appearance only in prologue and they do not play any significant role later in the story. This is not pokemon in Equestria, main character is a Kitsune. Warning, bleeding, religious themes and fluff is to be expected.

"Darkness beyond blackest pitch, Deeper than the deepest night." Those words echoed through her dreams from foalhood. However as she grew her bonds with her brother, her assistant and her mentor quieted them. Her bonds with her friends, the other elements, silenced them. But what happens when those bonds break? When all she loves turns their back on her. What happens when the Nightmare awakes?

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

Whilst enjoying the company of Twilight Sparkle and her friends in the doughnut shop immediately following the events of The Best Night Ever a disappointed Princess Celestia send a letter off to Prince Blueblood explaining the implications of his failure of the "Rarity Test", among other things...

Shining Armor and Cadence's spell reveals something completely unexpected as it expels Chrysalis and her changelings out of Canterlot: A secret kept from everypony for several years...

Now with a TV Tropes page! Warning: Will Contain spoilers.

Desert Mirage lives in a world full of guns, lasers, explosives and people competing to be the best of the best. There she excels at what she does: hunting. She started as a nobody, and yet became one of the most sought-after gunslingers.

Sunset Shimmer was practically born the best of the best. Selected by none other than Princess Celestia to be her prized student... until she ran away to another world in search of power. Through trials and suffering she was eventually taught humility and friendship.

At first blush, they don't have much in common. But their connection runs deep, and sooner or later it will change their worlds forever.

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.

Meet Level Ledger, your average, well-read unicorn colt. He has a talent with numbers and systems, which is why Pegasus Air was so interested in acquiring his talents. They use him to make sure their books are balanced. Both the legal ones...and the ones that'll never see the light of day.

Meet Midnight Song, your not-average, well-trained Thestral mare. Everything she sets out to do, she accomplishes with aplomb. When she rises a little too quickly through the Day Guard's ranks, her superiors decide she needs to cool off and learn a bit about how to be a mature member of the Guard. Not a bad idea, seeing as she's a massive flirt.

When Level's rent goes up, he needs to take a roommate or risk being thrown out into the street. A twist of fate will see these two souls coming together and having the time of their lives.

Now, if only one of them could tell the truth to save their life...

A collab fic worked on by myself and Ausbrony. We liked the setting of Las Pegasus and the villains of Pegasus Air a lot, so we put our heads and characters together, and this came from our efforts.

In lieu of a list of dates, I will simply say that this story tends to get featured every time I update it for a short while at least. And I am very happy about that fact.~

This story is a sequel to Reformation of the Hives

Even though the threat of the jungle queens and Grogar have been diminished, life often times does not get wrapped up in a neat little bow. More troubles present themselves large and small. Our only hope is we keep passing life's constant tests, even when it is the last thing we wish to do.
