It has been a decade since Twilight Sparkle was crowned sole Princess, and Equestria is at peace.

The Crystal Empire, not so much. King Sombra is apparently unkillable, despite all efforts. He returns several times a year to be destroyed, leaving behind his horn and always swearing vengeance. The jaded Crystal Ponies, some literally jade, have grown used to their tyrant attempting to return. Princess Cadance rules with her husband Shining Armor, while their daughter Flurry Heart excels in school. All is well.

All seems well, until Cadance begins to suspect that something is wrong with her daughter after the latest battle with Sombra. Flurry quite literally walks off a blast of concentrated dark magic. What Cadance discovers will shake her family to the core and upend everything she thought she knew about her daughter.

Flurry Heart is evil. If Cadance cannot save her daughter, she must stop her before it's too late.

Twilight is on a mission. There are twelve missing ponies to find, whether they be dead or alive. But what she finds will destroy everything she believes in. The Equestria she knows is not all that it seems. But there is one who will set everything straight.
"It is said that history is written by the victors! And the victims' bodies are lain in a bloody heap, left to be forgotten. Well, I have seen through the victims' eyes and seen the lies you have spoken! No more... No more will your lies infect me! "

"Sunset, you weren't the first unearthly threat to come to this world, and you won't be the last. If we seem calm in the face of strange events, it's not because we're oblivious or indifferent to them. It's because they're not strange to us. The Fall Formal may have been the most important night of your life, but to us... it was Thursday."

(Slice-of-life adventures of Canterlot High's unlikely band of monster hunters.)

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.]

Season two is live here, Season 2

This story is a sequel to Twilight gets a Puppy

Join the Sparkle siblings as they deal with Chaos, live through Nightmare Night , survive the CMC, deal with charlatans, giants, dating, and the wedding of the century.

All somehow without strangling each other, or their friends.

[ 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.]

Research log #579

It's been over one and a half years ago since the last activation of the device, though the magical signature hasn't changed it seems... weakened, to such a degree that the re-activation is impossible.

As described in the notes of research log #249 any attempt at providing the device an artificial source of magic to power failed, the device simply needed more energy than even the combined magical power of both Princess Luna and Celestia were capable of providing. You must be wondering now, I've already described these circumstances in previous logs so why bring it up now?

Simply said I'm out of options, every attempt of reactivating the device have failed and I'm only left with a single choice. I'm going to have to reverse engineer the device in an attempt to understand the mechanics with which it operates...

...At the risk of maybe never being unable to reconstruct it later.

I'm so sorry Fluttershy, I never should have involved you or any of the girls in the exploration of this structure. I hope that if we ever see you again you can find it in yourself to forgive me.

-Twilight Sparkle

In the true sense of Mass Effect, this story will be CYOA (Choose Your Own Adventure) giving you the reader the choice to decide the action of our protagonist.

I hope you enjoy!
