This story is a sequel to The Sword Coast

The shadows of the past plague the present.

Twilight Sparkle stands on a precipice, one false step from a dark destiny. Months ago, she set out to find her foster father’s murderer. After she defeated the Black Knight, she was hailed as a hero, but what she remembers most is the lives she took. On the path of strife, she discovered more about herself than she ever expected.

With her friends by her side, Twilight sets out for Canterlot, seeking the villain responsible for the death of her father and the crises that plagued the Sword Coast. On the way, a sadistic spellcaster interested only in power intercepts her and promises to unlock her potential. In the aftermath, Pinkie Pie is taken captive by the secretive wizarding order that rules Canterlot.

Twilight’s journey takes her through the doors of a prison and into the depths of a forgotten place. She encounters horrors made from nightmares and soul-stealing beasts raised from the black of the Abyss, but what she fears most is the monster within. How far will she go to save her closest friend?

When a dark enemy begins hunting the young wizard Twilight Sparkle, the walls of the fortress library of Candlekeep cannot protect her. Not even her mentor, the archmage Star Swirl the Bearded, can keep her safe. With a price on her head and the shadow of death on her heels, her only hope for salvation is the Magic of Friendship. Perhaps, with powerful allies at her side, she can find answers and uncover the truth about her destiny.

(This story is inspired by the Baldur's Gate CRPG series by Bioware, but you do not have to be familiar with BG to understand its events)

A damaged robot pony, unlike anything ever seen in pre-industrial Equestria, is found in the orchard. Before it collapses, it says only two words: "Twilight Sparkle..."

Twilight fixes the mechanical mare and gives her a new directive: "Make friends." Now a robot must learn what it takes to be a good friend and, while she's at it, what it means to live...

All Twilight wanted was to give Spike a special gift for his birthday. Yes, it was a book, but it was a very special book. An Enchanted Book like that Power Ponies comic they had recently experienced.
Things went wrong when Spike startled Twilight as she was working the spell for his (secret) gift. Needless to say, startling Twilight while she's in the middle of a spell can be a bad idea - as certain frogs can tell you.
Twilight has every reason to believe that she is now trapped in a closed reality bubble fabricated out of her own magic, with no way out. She's lost in some made-up universe reflecting some random story line.
Mike, of course, has a different opinion about the matter.

WARNING: Both Twilight and Mike love talking technical and explaining things to each other.

This story is a sequel to Dresden Gets Schooled

Harry Blackstone Copperfield Dresden's life has been even stranger than usual ever since he first got involved with Equestria. However, after his last adventure sent him to some strange high school dimension, things have finally settled down into something approaching normalcy. Or at least as normal as Harry's life ever gets. His new apprentice Sunset Shimmer is proving to be quite a handful, but Harry has experience with handling headstrong young women.

However, things take a turn for the worse when he learns that a new threat from Equestria has made its way to Earth. And naturally it's up to him to stop the Sirens before they rock the world's foundations.

In 2185, during his campaign against the Collectors, Commander Shepard discovered a previously unknown species whose origins predated any other race in the modern galaxy. Following a daring rescue from their ancient sanctuary, the Equestrian Herd was brought back into the galaxy where, for the first time in eons, they must walk their own path.

Knowing full well the terrible threat that lingers on the edge of the galaxy, the leader of this newly freed race fights to secure her people’s future while attempting to prepare for the storm on the horizon.

This is her story.

This story is a sequel to The Dresden Fillies: False Masks

It's been a while since the girls have seen their good friend Harry Dresden. Discord escaped, Luna attended her first Nightmare Night, the Royal Wedding was crashed by hordes of changelings, and Pinkie Pie threw a statistically improbable number of parties. They tried inviting Dresden, but between his new job and new apprentice, he always claimed to be too busy. The solution was obvious; if he couldn't come to his friends, they needed to go visit him. Besides, they say Earth is lovely this time of year. What could go wrong?

Crossover with the Dresden Files. Sequel to Forever!

For his first task as the new Winter Knight, Harry must travel to the land of cute little cartoon ponies to stop a plot by the Order of Blackened Denarius that threatens both Earth and Equestria.

Warning: Includes massive spoilers for the Dresden Files series up through Ghost Story.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.
