Rainbow Dash flies east.

Eighty years after the events of The Dread Chitin, Equestria is a radically different place. The arcane science of the late Duran Thirk and the information found on the Star League library core have combined to catapult the nation's science ahead by hundreds of years.

Now, facing the possible aggression of a completely unknown alien power, Twilight Sparkle and her friends have to gather together once more, leading a crew of the best ponies they could assemble in a voyage outside their own star system. They seek to learn about their potential foe, to explore the galaxy around them, and possibly find allies and friends to stand alongside them. Who knows what they will actually find?

Stranded on a hostile, alien world, Twilight Sparkle and Rainbow Dash must depend on one another and a fellow alien castaway if they want to return home to Equestria.(originally published on FFN)

This story is a sequel to Changeling Courtship Rituals

After many years of battle, Queen Chrysalis has finally defeated Twilight Sparkle.

To Twilight's surprise, she discovers that to changelings, this means they are now married. However, she has some thoughts about this...

***

A reboot/remake of Changeling Courtship rituals, where Twilight reacts in a much more normal way, rather than like a sitcom character.

It occurred one peaceful night. Half of Equestria awoke to the sound like a double-shot thunderclap. A percussion heard in the skies and rattling windows from Apploosa, to Canterlot, to Ponyville. Nopony knew what it was or what it heralded for the world as it drew a line across the nation.

For Twilight Sparkle, this isolated incident might have faded from memory after a time, if not for the strange rumors of a creature sitting on the hill on the outskirts of town.

These are her thoughts given written form. These are Sparkle's Notes.

Report EVERYTHING to the Princess.

In the 31st Century, humankind has spread to thousands of planets in the Inner Sphere. Once united under the glorious banner of the Star League, the Successor States and their noble houses now fight bitter wars over the scraps of empire. When a JumpShip carrying a special task force from the Federated Suns suffers a catastrophic misjump, the occupants find themselves stranded above a strange, beautiful world at once alien and eerily familiar.

Meanwhile, in the peaceful realm of Equestria, Ponyville’s resident bookworm , Twilight Sparkle, has stumbled upon hints of a secret buried for centuries. A secret that may lay bare long-forgotten aspects of Pony history and culture.

Our story begins on the planet Valexa, where the beleaguered Militia has launched a last-ditch effort to call for help against overwhelming odds.

Written with those who are not familiar with the BattleTech/MechWarrior universe in mind.

This story is a sequel to Habits of the Equestrian Phoenix

After going to Coloratura's concert, Sunset gets both good news and bad news.

Somepony stole her identity and is running around with her face.

That's the good news.

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.

  In a world where the stars shine through both day and night, a savage attack upon the Phoenix Tower of Canterlot Castle leaves the city in chaos, a princess abducted and the stars fading from the sky.
  Now, Princess Sunset Shimmer dons the legendary Solstice Raiment and the Flareblades of the Sunmother in a desperate quest to save the glittering heavens and the love of her life.
  Because if the stars die... her world will soon follow.

For years, Twilight Sparkle and Queen Chrysalis have been at each other's throats. Both have experienced victory over the other, and both have experienced defeat. Out of all the creatures in Equestria, none despise each other the way the pony Princess and changeling Queen do. They seemed destined to remain locked in battle forever, or at least until one is finally dead at the hooves of the other. The cruel insults, the vicious loathing, and the powerful spells that have passed back and forth between them at each meeting have become the stuff of legend.

Imagine Twilight's surprise when she finds out changelings consider this dating.

And now they're married.
