When Twilight Sparkle had the magical surge that cemented her place as Celestia's student, the amount of power she released not only hatched a baby Dragon, it brought forth something else. Something that shouldn't exist any more.
Something that has Celestia worried.

A fluffy puppy.

[Despite the gore tag it's rather light on that, and they have yet to make a lewd tag and there's a bit of that.]

[ Despite having to tag the story with Gore it is light on that. It is however somewhat heavy on innuendo and lewdness, but there's still no tag for that.]

[ It would also be good if you read the first book as it ties directly into this one.]

[ LINK TO SEASON 3 ]

This story is a sequel to Tails of Innocence

It has been over 50 years since Princess Celestia took in a little three-tailed fox as her student, years filled with affection, teaching, discoveries, and love, raising her in the hope she could purify Luna from her corruption.

Now the day has come as the seal holding Nightmare Moon trapped is about to break. It is up to Kyuubi and Twilight to save Princess Luna.

Will the five-tailed kitsune step up and succeed? How will Ponyville react to a four-meters tall but fluffy predator? And most importantly, what struggles and sacrifices will be needed to achieve victory, and who will have to make them?

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.

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.

Adagio liked running the world, she really did. The power, the riches, and, most importantly, the adoration was what she lived for. However, even conquering empresses had off days or needed breaks. Thankfully, the Royal Band plays a melody to soothe their fatigued ruler. Of course, what really helps is Adagio's favorite servant, and the way she moves.

The Battle of the Bands had been a week prior and the Sirens were not taking it well. Without the ability to feed, they can't survive very long. Deciding to just wait for their time to come, the sisters spend their last night out at a restaurant, dealing with the symptoms of their hunger. They were expecting the Grim Reaper to come for them, scythe in hand. They were not expecting someone else to show up.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.
