In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

A millennium ago, give or take, Princesses Celestia and Luna were nearly defeated by the most powerful villain that they had ever faced, Grogar, the dreaded lord of Tambelon. Thanks only to the whims of random chance, the two princesses survived that encounter, but have been forced to live in fear of the time of his inevitable return. That time is now...

...But whatever revival was intended has gone a little... wrong. Behind the wheels of Grogar's body is the spirit of a slightly extremely eccentric human. Equestria would have been lucky to survive the real Grogar, but will the ponies fare any better with this loon ruling Tambelon?

This story is a sequel to Convergence

Equestria was just a game, one of an endless number of semi-illicit online games created to take advantage of the ubiquity of cheap augmented reality hardware. But that changed, when for no reason anyone knows, the virtual population of Equestria woke up.

Two decades have gone by since then, and the world has been transformed. The former game network has grown to encompass the backbone of trade, infrastructure, and research the western world over. Its vast computational resources have given rise to an infinitely subdivided world of overlays and sublayers, coterminous with the various cities and towns within Equestria. Every person in the modern world is assigned a Synth, a pony personal assistant that adapts to their needs and helps them access those parts of the world governed by Equestria's systems.

It is a world Dakota barely remembers, thanks to an automobile accident that turned most of her body to mush. But thanks to the medical miracles created by joint equestrian-human research, her life is saved by a remarkably new series of implants.

But Dakota isn't content to sit around while her body slowly knits itself together. There are unanswered questions to answer, questions that will ultimately lead her to the oldest mystery of both worlds.
