Rarity and Twilight are dating. Rainbow Dash just asked them both out as a joke.

She didn't expect them both to say yes.

Rainbow Dash's morning was pretty much ruined.
She tripped getting out of bed and landed flat on her face, giving herself an aching muzzle.
She forgot to buy her favorite brand of hay flakes at the store yesterday and had to eat plain toast for breakfast.
She found out she had to pull double-duty today and tomorrow on the weather patrol.
Oh, and she found a nearly-dead foal, broken and bleeding at the edge of Ponyville.

The rest of her day became a whirlpool of stress and worry but the colt woke up, thank Celestia.
Something's not right, though. Nopony can find his parents, he's not in the registers, and there's an unsettling look in his eye...

Sunset Shimmer knew she was better than the other ponies around her, even if she didn't have her cutie mark yet. She had to be.

She just needed to find a way to prove it.

Applejack, Twilight, and Rainbow Dash really enjoy each other's company. So much so that some ponies are beginning to wonder about them. Twilight and Applejack are a couple after all, so its a bit unusual that Rainbow always seems to be invited along. But sometimes, a couple is more than two.

When Twilight Sparkle was just a kid, her best friend was a girl named Sunset Shimmer. Though their friendship had a bit of a rocky start, they quickly became inseparable, no matter how much everyone thought of them as ‘weird’. They were there for each other.

Were.

Years after the tragic accident that tore them apart, Twilight is determined to move on from her loss, and she sets off on an independent research project to investigate the strange happenings at Canterlot High. Little does she know that she will soon come face to face with what appears to be a literal ghost from her past.

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.

After the catastrophic failure, and subsequent destruction of his spacecraft. Captain Randolph 'Randy' Edwards is crippled, lucky to have lost only his lower legs to the burning thanks to the heroic efforts of Princess Luna. With the relief of all his friends on Equis, now it was only a matter of time before Randy's race followed up on his discoveries. Though instead of flying ships descending on the planet once again. Humanities response came with a simple little ping.

(A sequel to Arrow 18 Mission Logs: Lone Ranger)
It all started with an unexpected visitor. A single, curious individual from farther away than anypony could ever have fathomed. At first, a curiosity of a creature to be minded by the Princess' protégé. Then a spectacle as he took ponies where they had never gone before. And finally, an ambassador who brought an entire planet together with the simple realization that there are more important things out there than petty squabbles.

And it all almost went up in a fireball.

But friends don't let friends die so long as they have the power to rend the heavens on sheer force of will.

Now stuck in a hospital bed, Captain Randolph Edwards, commander of the one-man space mission to the anomalous planet known as "Equestria", must wait for a rescue that will be a year in the making... Minimum.

What ever will he do with himself?
