With the Clone Wars long over and the Galactic Civil War not yet begun, Emperor Palpatine has focused the Imperial Military on pacifying the regions on the edges of the Galaxy and expanding the reach of the Galactic Empire. The Unknown Regions have long been separated from the rest of the Galaxy by the Hyperspace Disturbance, but determined scout groups still manage to find routes to explore the strange worlds beyond. One such expeditionary force has stumbled upon a world that seems ideal for human habitation, but there's just one problem - it's inhabited, and the local alien population is proving far more difficult to subjugate or remove than expected...

Two thousand years after the return of Princess Luna, Equestria's technology and magic has advanced far enough that the once far off dream of faster than light travel is now a reality.

And that reality is the ES Harmony, the pride of its designer, Princess Twilight Sparkle, and Equestria's first FTL capable starship. It is due to make its maiden voyage to travel further than anypony before it.

And yet when they receive a distress call from origins unknown, this ship's maiden voyage will become one the crew will never forget.

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.

Friendship, the Final Frontier.
When a Starfleet ship discovers that the Orion Syndicate is enslaving ponies, her commander decides to do a good deed and return the rainbow-maned pegasus home to Equestria. Things don't go smoothly for the crew of the USS Judges, but what they find may be one of their biggest discoveries ever.
A Friendship Is Magic/Star Trek Online crossover.

This story is a sequel to The History Of The Human War

First state visit to The Human Refuge's home, Luna Aeternal is happening. What will happen? Twilight Sparkle accompanies Princess Luna as she visits the human colony on the moon. What kind of place is the mysterious human home? What will she find there? And will they survive the visit without restarting the most devastating war in the history of Equesteria?

Sort of sequel to The History of Human War. Originally planned to just add this to that fic, but it kept growing until I had to split it into two parts and then it kept growing until it started to be longer than other "After The War" chapters combined. So now it is its own story. Enjoy.

It is the year 2012. When military pilots discover a previously
uncharted Bermuda triangle-like area in southern Oceania, a cordon around
the area is established.
Soon it is noticed, that inside the cordon, there is a large, isolated and
utterly undiscovered land mass. And it is inhabited, too.
The UN, upon realising that the inhibitants' civilisation seems to be
highly advanced and organised, decides to send a diplomatic mission to
make a proper first contact, and to achieve a peaceful cooperation with
the rest of the world. Had they only prepared both sides properly, they
may have not have had the risk of a full scale war...

This Fanfic will be posted in form of two... no, four scenes per week.
It is, as it heavily relies on dialogue, kept in form of a piece of theatre, (with music cues and all). Please don't judge too harshly, it is my very first piece of Fanfiction, as well as a Pilot (as I will most probably post sequels to this to flesh out side characters). Please leave lots of feedback in your comments on what I can possibly improve. You'd all be really helpful.

Enjoy.

A lawyer doesn't always want to know what really happened. It's a tightrope walk. Whether or not the lawyer believes in his client's innocence is not the issue. It's his duty to defend his client - no more and no less.

Nearly one year has passed since Australian pilots discovered Equestria in the middle of the Indian Ocean.

Now the world watches in awe as, with the Princesses' blessings, one of the most ferocious and dangerous tyrants of the equine world - none other than Chrysalis, the Queen of all Changelings - is marched before one of the highest courts of law of the human world - the International Criminal Court in The Hague, the Netherlands.

But the Queen is wrathful and determined, still one of the planet's single most powerful creatures.
How can mere humans, who know next to nothing of her mystical home, achieve justice for the Equestrians?

Alexander Estermann is a conceited defence attorney who will have to wade through a quagmire of vengeance, racism, manipulation, lies, hearsay and self-deception to get to the core of the affair.
Seemingly the whole world is working against him - up and including the Queen herself.

Rated teen for liberal swearing and gore for minor gory descriptions and pictures.

Disclaimer: This is not a story that is meant to reflect reality. Several things about international law have been changed to accomodate the scenario and make it, well, readable. If that should offend you for any reason, I wish to apologise in advance.
