After discovering that Cadence is not who she appears to be, Twilight is sent to another world entirely by the disguised Changeling Queen to avoid her plan being disrupted.
When Twilight lands, she discovers that not only have Spike, Owlowiscious and Peewee followed her, but that they've arrived in a world where the main sentient species is human.
There's still a place where they teach magic, though.
Crossover with Harry Potter. Twilight will be effectively taking the role of Hermione.

I've marked this story as cancelled to reflect the unlikelihood of it continuing. If I do come back to it I'll revert that.

This story is a sequel to Scion of Chaos

Five years after the summer in which the three had gotten their cutie marks, Scootaloo, Sweetie Belle and Apple Bloom, now young mares in their own right, decide to go on a quick summer vacation, all as an attempt by Sweetie Belle to cheer up a sad friend. However, the trip turns out to be more than they had anticipated.

Set five years after Scion of Chaos and An Emerald Treasure. For the sake of context I'd recommend reading both of those first.

Special thanks to Mac349 and Plebeian for proofreading. Thanks to CMC4TW for editing/idea-mulling.

This story is a sequel to Justice

Worker's dreams have taken a turn for the worse. Feeling trapped, unable to talk about his experiences and unable to stop the near-nightly terrors, he wonders if he should reach out to the Princesses. It never occurs to him that these nightmares might be something more.
This is the final story of a trilogy. The first part is Order from Chaos, and the second is called Justice.

It's winter in Ponyville, and Diamond Tiara is queen of the Hill. Can the Cutie-Mark Crusaders cast her from her snowy fortress?

Lyra explains the unfortunate series of events that drove her to cry when the parasprite devoured her pie. Very minor shipping elements, with Bon Bon, obviously. It was inevitable.

Applejack tells a story she holds close to her heart.

A first-person(pony?) narrative from AJ's PoV.

This story is a sequel to Scion of Chaos

After returning to Ponyville from Canterlot, Sweetie Belle tries her best to find her place amongst friends and family and to remember what it feels like to be home.

This story takes place 4 days after the finale of Scion of Chaos. (I recommend reading that first, if you haven't already)
And set 5 years later is the sequel story: A Heart of Change

Thanks to Rameslack for his amazing cover art.

Sweetie Belle is compelled to learn magic after Rarity promises to teach her the finer art of dressmaking, but only once the young filly has learned the basics of magic. However, learning magic comes with its own set of complications and bears an unforeseen gift that will change Sweetie Belle's life forever.

Here's a one-shot sequel that takes place four days after Scion of Chaos: An Emerald Treasure

And this is a Multi-chapter sequel that takes place 5 years after the events of SoC and AET: A Heart of Change

Here's a poem that's based around the character Red Timber. (Not necessary to read for the comprehension of the storyline): Red Timber

On the advice of her sister, Celestia sets out to investigate and resolve the lost connection with her most faithful student. What does it mean to be a Faithful Student...or a Princess of the Sun?

Earned a six-star rating on Equestria Daily and featured on its very own TVTropes page!.

Things couldn't possibly get any worse for Rainbow Dash. Her job is falling apart, she's convinced that she's made her friends hate her, and even her dream of some day joining the Wonderbolts is in peril. While things are looking pretty bleak for Ponyville's coolest pegasus, her best friend and kinda-sorta fillyfriend Pinkie Pie is determined to whatever it takes to help her, and she's not going to quit until she can put a smile back on Rainbow Dash's face.

This is a side-story of "The Life and Times of a Winning Pony" which occurs after the events of Chapter Ten of that story.
