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.

While he has returned from being absorbed into Unit-01, Shinji finds himself in an odd situation. Now, in a body that looks nothing like a human's and with a snarky roommate in his head, he has to deal with new powers and abilities while those around him shift.

And he thought that fighting Angels was weird...

While experimenting, Twilight's new teleportation spell goes awry, sending her careening into a different world, just in time to take part in a fantastic ritual called Heaven's Feel. Twilight must adapt to the world of humans and take part in the vicious conflict that is the 4th Holy Grail War as a Servant alongside her equally reluctant Master. The duo must contend with powerful adversaries and survive the subtle machinations of the Magi determined to win the Grail at any cost. Can Twilight overcome her unwillingness to take the lives of others? More importantly, should she? And is there any way for the displaced Unicorn to return home? Trapped, alone and in a different world and surrounded by enemies on all sides, does the Magic of Friendship still hold any hope for Twilight?

A crossover with Fate/Zero.

1300 years. That is how long Princess Celestia has ruled her kingdom without a break. But it was not meant to stay that way because Luna and Twilight managed to find the millennia old record and revealed a horrible secret. Princess Celestia has nearly 100 years of unused vacation, and as a good student and sister they have no other choice than to force Celestia to take that time of. It wouldn’t have been so bad if a magic portal didn’t appear right when her holidays were about to start to whisk her away into a unknown world.

mlp/zero no tsukaima crossover

Big shout out to my great editor Poliamida for being awesome.

Bad things happen. Good things too, but mostly bad things. Sometimes, your wagon gets destroyed by a giant bear. Sometimes, you make a bad reputation in some town you promise to never visit. Sometimes, you compulsively splurge most of your savings on some fancy-looking trinket that you won't even wear. But getting sucked by a fiddlestinking portal to another world?

Well, not unless your name is Trixie.

[A Familiar of Zero Crossover]

If you could peer into the future, and see the exact cause, and time of your demise, how would that change your life? What if you saw the future and learned that that day was today? That's the dilemma Cozy Glow is faced with in this alternative version of the Ending of the End. In a dark twist, she uses Discord's chaos magic to take a peek into the future, and catches an early glimpse of her devastating defeat. Is there a way to prevent this horrible future from coming to fruition? Or is Cozy destined to an eternity of suffering? What does it take to make the change?

My second entry for the Cozy Glow Short Story Contest

Prompt: Cozy’s got a secret! Whether or not it’s hers is for her to know and you to find out.

The worst part of a betrayal is often not the act itself, but everything that lingers after. Trying to piece together the motivations of someone you once trusted, sifting through memories for some sign you might have missed.

Wondering if, somehow, they had a good reason behind it all.

Seeking closure, Twilight tries to find answers in Cozy Glow's abandoned possessions, but the truth she discovers is one that will make her question everything.

Written for the 3rd Annual Cozy Glow Short Story Contest.

Prompts used:
-Twilight Sparkle gathers Cozy’s belongings for disposal. One object surprises her.
-Cozy’s got a secret!

Twice in Equestria's history, an unhinged flying pony has attempted to take over before being sealed in stone as indefinite punishment. The first failed usurper didn't mellow at all during her sentence. The second one though...

Moody, atmospheric character vignette that got 2nd place in the Cozy Glow Group's August 2020 Short Story Contest. Golly, am I honored.

Not all villains are evil. Some are just misguided. There are some creatures who just need a helping hoof to have the opportunity to—

—bwa ha ha, no, the Queen of the Changelings would never be into that. So what's with this sudden change of heart? And what's with these sassy letters?

A not very serious fic with some isekai implications.

(Spoilers for the series finale)

Cozy Glow was supposed to be stripped of her phenomenal, cosmic power when she was defeated.

Instead, she just lost her memory. Having super powers and being pursued by the authorities, she comes to the only obvious conclusion a comic-reading child could:

She's clearly a superhero vigilante!

A trainwreck of idiotic decisions follows.
