Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

Ten years ago, the Griffon Empire opened a portal to a strange new world and tried to annex it. In the peace settlement that followed they lost control of the province containing the portal. Since then, the Griffonian Democratic Republic had been completely isolated, surrounded on all sides by a hostile empire. Now, for the first time, a visitor had been allowed.

Twilight has a brand new theory. She has theorized that it is possible to create pocket dimensions and a way to enter them. Facing the ridicule of the rest of the theoretical magic community she has set forth to prove them wrong. She will construct a portal and enter it.

She does. Inside, she finds a field of empty white.

The story now has a dramatic reading by MrSnarky. Visit his channel on youtube.

Twilight's relentless study of Pinkie's strange abilities leads to a horrifying revelation.

This site really needs an existential horror tag.

The Changelings have been defeated and Shining Armor and Princess Cadence have said their vows, but that still leaves the Mane Six and others with the issue of the strain on their friendships. And among all the guests present at the reception, a few of them are going to be suprised with what new relationships are formed.
