A soldier from the frontlines of the Equestrian Civil War returns home, out of place and out of touch with the world that he once called home and struggles to fit in. Little does he know his past will be coming back to haunt him.

Fluttershy has always had trouble finding her voice, confident only when surrounded by her animal friends. So of course she's eager to take in a small blue creature she thinks needs her help. But when her newest guest begins destroying everything, Fluttershy may have to find her a voice a little sooner than she expected.

As the Zentraedi launch their relentless assault on Macross Island, Captain Gloval makes a desperate decision; to make a hyperspace jump to outflank the alien fleet. However, something goes horribly wrong and the ship warps across the galaxy to an unknown planet... along with Macross Island.

And the planet is not uninhabited.

With no hope of returning home in their lifetimes, the crew of the ship and the people of Macross Island are in seemingly poor straits.

There's a special clinic for unwed mares who want to have a foal. Everypony knows it exists, even if nopony really wants to talk about it--or to be seen visiting it.

It's called the Family Planning Center, and today, Twilight Sparkle is going there for the very first time.

Update, 23 October 2013:
The "Planningverse" is now officially open, and as such, this story has been retagged "Incomplete", as myself and others will be expanding upon the basic concept here within the core story.

(Rated Teen + Sex for obvious reasons, but this story is not technically clop.)

Hi, my name is Ditzy Doo. Many of you know me as the author of the 'Wasteland Survival Guide'. For 200 years I wandered the Equestrian Wasteland, and through those experiences I gained the knowledge that I shared with everypony through the Guide. Now, it's time to tell my side of the story.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

It's been a thousand years. Princess Luna is returned, and the castle staff must scramble to see that she has servants to attend to her needs, and just as importantly, that they look the part. Of course, it turns out that it's rather difficult to find competent servants on such short notice. A hooffull of servants are chosen based on their appearance and duties, and are assigned to serve the Moon Goddess as personal retainers until more suitable replacements can be found. When coloring, Cutie Mark, and chance coincide, one of the castle's junior stewards is thrust into a role any loyal servant ought to jump at: Lunar Hoofservant. Unfortunately for Nightlight, Princess Luna is far more demanding than her older sister, and being her servant means contending with an unforgiving goddess who demands nothing short of perfection. Furthermore, somepony must be responsible for the inevitable failure. The duty of "Royal Hoofservant" just might be synonymous with "Royal Scapegoat."
Saddled with responsibility far beyond his post and expected to fail, Nightlight has no choice but to quit his post or to become the servant that Luna needs. This is the story of a pony's development from colt to stallion, and from servant to leader.
Thanks much to DirePony for the editing and story direction he's graciously provided me.
Rated 'Teen' for alcohol use, mild innuendo/sexual references, and pony-swears.
Not based on the (excellent) sci-fi novel of the same name by Robert Heinlein.

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.

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.

Cheer up, Twilight. It's not every day somepony changes species. In fact, no pony has ever changed species. It's something new and you like discovering new things. Granted, Equestrians don't like new things, especially things that fundamentally alter their government. So maybe there is reason not to be happy after all.
