Twilight Sparkle has recently transferred to Canterlot High. On top of tests, studying and all the drama that comes with that, Twilight also has to deal with monsters. Yeah, you heard right. Twilight finds herself embroiled into an age old conflict that could rip the world apart, if she doesn't step up and become a Guardian, a defender of earth from the forces coming forth from the Witching Hour. Twilight cannot face this threat alone, others will join her fight. But will it all be enough to stop the evil that's coming? Or will High School be what gets this young lady?

(A new story from the creator of Equestria Noir. While characters from that universe will be present in this story, strict knowledge on that series is not necessary to enjoy this story.)

A curator was found murdered in his own office, guarding a journal from EW2 era Equestria. The journal as it turns out, belonged to a former detective. A tale of forbidden love, a feud between sisters, and a legendary medallion. Can Private solve this murder before history begins to repeat itself?

(Based heavily on the Castle episode 'The Blue Butterfly')

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.

When Twilight Sparkle was just a kid, her best friend was a girl named Sunset Shimmer. Though their friendship had a bit of a rocky start, they quickly became inseparable, no matter how much everyone thought of them as ‘weird’. They were there for each other.

Were.

Years after the tragic accident that tore them apart, Twilight is determined to move on from her loss, and she sets off on an independent research project to investigate the strange happenings at Canterlot High. Little does she know that she will soon come face to face with what appears to be a literal ghost from her past.

Twenty years after Luna’s second rebellion, the pain of her rebellion has yet to heal as Celestia withers in isolation.

Yet sometimes the scars that were most carefully hidden, cover the deepest wounds.

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

Meanwhile, on the newly discovered world of Harmony, humans and ponies work together to study this strange new world. However, their arrival causes something ancient to begin stirring. Something that may end up changing everything.

On the eve of the Summer Sun Celebration, Spike discovers all of Ponyville has been trapped in a deep sleep by an unknown enemy. What's more, even he himself is falling victim to the spell. Fortunately, the Princess of the Night is wide awake, even when she sleeps.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

Warning: this story is a sequel. Therefore, it is highly recommended that you read the prequel first before continuing!

Over half a year has passed since the changeling attack on Ponyville, and Applejack would like to think things have finally settled down. Much has changed for the young changeling, and all of Equestria in kind. The new district in Ponyville proves that, along with the town's many new residents.
But there is much the young queen does not yet know about being a changeling. Some things, she will learn, can be chosen, while others will be chosen for her. With new allies and enemies emerging all around her, Applejack must discover what it truly means to rule before the choice is taken from her forever, and the history of the changelings repeats itself, once again...
