Twilight Sparkle - magus, heroine and Princess - has learned of worlds overlapping Ungulatia in space and time. Though this has been a well known phenomenon, safely traveling to these other worlds has always eluded pony mages. But now - after years of research and careful experiments - she prepares herself for the most audacious of all experiments: stepping hoof on the surface of an alien world and returning safely! What wonders will she find once she walks through her magic portal?

This assumes that Equestria Girls never happened.

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.

Twilight's World now has an audio reading by No One and Nobody. Listen HERE.

This most excellent cover art was provided by Void Heart

Ponyville, Equestria. Population 5000.

Fallow Meadows, Indiana. Population 8000.

Two towns, two species, two worlds.

But worlds will collide when both are hit by mysterious storms that transport them to a third world unknown to either. Trapped in a place hostile to them both, can human and pony learn to work together? Well, yeah, the story wouldn't be called Unity otherwise.

The real question is what happens when it turns out that they are not alone...

After years of shame and ridicule, archaeologist and explorer Lyra Heartstrings stumbles across a discovery that validates all her theories and ideas in one fell swoop. Along with her best friend, Bon Bon, and her old classmate Cadance, they find themselves faced with a mystery and marvel that may change everything.

Following the next greatest lead found in the database of an ancient race, another international team is formed. Led by Doctors Carter and Jackson, they strike out to explore another network of Stargates discovered in a galaxy on the edge of the local cluster. In the process, their findings will cause them to question much of what they thought they knew.

The adventures continue and unlikely allies will face dangers new and old as the Legacy of the Ancients continue to unravel in the latest chapter of the universe.

Now with a Russian reading by SviMik

As fate would have it, Twilight had to hatch a much bigger egg this time.

Celestia is trapped on Earth.
Not as a human. Not as an alicorn. She's a common horse, an Arabian mare, without her magic, voice, knowledge of the language - not even freedom, forced to work at a riding school.

What can a single Arabian mare do to get back to Equestria from this backwater European country? With only the mind of a princess and a pencil in her teeth, Celestia must find a way home.

[Illustrated] [Alternate Earth] (without Bronies)

This story is a sequel to Harmony Defended

Ten years ago, Equestria was nearly destroyed in a combined invasion of its worst enemies. Only with the timely intervention of its erstwhile human allies was the nation spared slavery and extinction. The war is over now, and the treaties of peace faithfully followed even after a decade. While earth ponies help rebuild Earth's ecosystem, human tractors erect roads and cities with terrifying speed.

Sweetie Belle helped make victory possible, but the cost of that victory was one of her best friends. Equestria is safe now, and ponies are spreading to the stars. Why doesn't she feel happier?

This story is a sequel to My Little Apprentice

The summer sun celebration brought the filly Second Chance into contact with one of the most powerful beings in Equestria, Discord. Thanks to him, she's got all her memories back, and has access to the powerful Jebr Stone. Will that be enough to save her dying species without sacrificing Equestria in the process? Nor is she the first traveler from her world to reach Equestria, or the only one with plans for it.

Will Chance's newfound friendships be enough to keep her sane and preserve Equestria through the dark times ahead?

This story is a sequel to The Last Pony on Earth

Alexandria; a name its founders hope might again become synonyms with scholarship in a world that only four months earlier hosted human civilization. Now only the last remnants known as the Human Preservation Initiative have retained their species, the remainder of the population has been transformed completely into ponies. Adapted to survive in a world now saturated with magic, the ponies of Alexandria settle in for what they expect to be long and boring lives.

They are mistaken. Between the gradual approach of winter, being completely new to the magic of their bodies, and the HPI constantly breathing down their backs, life in Alexandria proves to be anything but boring.

Until yesterday, my life was no different than anybody's. Go to work, pay the bills, sleep. Today, I woke up to a world without humans. The streets are empty, the power grid is running down, and not another soul is in sight. That might not be the worst thing, if I wasn't also a pony.

Where is everyone? Why is this happening to me?

Will l stay sane long enough to starve?
