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.

This story is a sequel to Destinies

Nearly a year has passed since the events that had brought two realms together. Each had kept the other a secret until now, two worlds separated by a certain cartoon. Finally, both are ready to deal with the inevitable complications, to realize the benefits of trade: human technology for Equestria, and magic for humanity.

The Princess of Friendship is convinced she‘s up to the task, while Meg‘s doubts over the true meaning of her cutie mark grow as the two worlds converge.

Read Destinies first. You won‘t have any idea what‘s happening if you don‘t.

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

Magic is bleeding out of Equestria and into another realm, a realm where magic does not exist. Twilight must stop the flow of magic before disaster strikes. Can the natives of this realm be of help? How do sapient beings function without magic anyway? What's this about a cartoon?

Takes place shortly after season four.

It's an ordinary day in Ponyville, until Applejack says Twilight is purple. She should have known better.

Mark Wells was a klutz, but even he could not imagine stumbling into a mirror that he had just bought at an antique store and ending up in a world of colorful equines, not to mention gaining hooves and wings at the same time. And whoever heard of green fur on a horse? Perhaps the great and powerful Princess that the guard was taking him to would have some answers because he sure didn't!

An alternative version of canon events with humorous twists. Written in collaboration with Airy Words.

Unable to recall why she's here, Twilight is told she has experienced a 'Game Over'. Then she is asked to start over. With eagerness she accepts.

Now with the ability to see reality in a way that can make Celestia envious, Twilight finds her life has quite literally started over.

Will she change the time line? Will she prevent the worst events she has ever experienced? And will she actually bother to level up Luck?

[Third Person]

Commissioned by Canary In The Coal Mine.

After losing his last living relative, Carter Arvil, former CIA Agent turned real estate agent, is approached by a mysterious woman who offers to sell him a magical kingdom. Assuming the woman is simply a little unstable and selling a magical pony styled theme park aimed at little girls, Carter accepts the deal. A deal which immediately takes a turn for the unexpected as the offer was exactly what it said on the tin and comes with several major strings attached.

Like having to be a pretty pink pony princess.

Her brilliant plan was ready to put into motion. All she had to do was get to the right place, then wait. How hard could that be? It wasn't like Twilight had any security measures of any kind.
