Upon returning home from a well-deserved vacation, Twilight Sparkle and her friends find Ponyville in ruins. To their shock, Princess Luna herself appears to be at the center of whatever happened. The princess is all too eager to share the tale, however, and proudly recounts the events that transpired while the gang was away.

Twilight Sparkle's imagination as a child was unbelievable, probably due to all those books. Which also make up the amazing Fort Book, Twilightopia's first stronghold against the country of Armor! With the help of Captain Smartypants and Private Cadence, General Twilight defends her fort against her brother's advancing army of one!
A tale of Twi's childhood told from her point of view.

Inspired by the cover picture.

The friends we take for granted are often the ones that leave the largest impact on our lives. When Spike falls seriously ill with a mysterious disease and the ponies strive to nurse him back to health, Twilight Sparkle comes to grips with this very realization about her number one assistant--and friend.

EDIT: So this little story made it on Equestria Daily on 10/8/12. Now please excuse me while I pass out on Rarity's fainting couch while murmuring a soft Fluttershy "...yay."

This story is a sequel to Post Nuptials

In the aftermath of the wedding, Spike is bitter and avoiding everyone. Twilight's determined to find out what's bothering her charge, but she walks a very fine line when dealing with an emotionally distraught child.

Meanwhile, Rainbow Dash suspects something's wrong with Scootaloo, so she starts spending more time with her in hopes of picking the secret from her brain. As she begins to truly mentor the young filly for the first time ever, she begins to see the advantages to having a little sister.

And while all this is going on, Pinkie is struggling with some old family issues that have been brought to the surface, meaning she might have to confront her past at last.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

The Changelings have been defeated and Shining Armor and Princess Cadence have said their vows, but that still leaves the Mane Six and others with the issue of the strain on their friendships. And among all the guests present at the reception, a few of them are going to be suprised with what new relationships are formed.

"It's so nice to see you again!" said the thing that was not Celestia. "Oh yes, I know who you are, Twilight Sparkle. I had a taste of your magic the first time we met. Mortals forget things so easily, I find. Allow me to refresh your memory: you tried to kill me. But you failed, Twilight Sparkle. You only mostly killed me. And I guess that makes you one very unlucky little pony."

This story is a sequel to Inscape

Penumbra seeks gainful employment. Hilarity ensues.

This story is a sequel to Petriculture

It's been several months since Pinkie Pie made a stunning admission about her past that permanently changed her relationship with her friends, particularly Twilight Sparkle, but life seems to have settled back to normal (well, normal by Pinkie Pie's standards, at least). However, when an old nemesis returns and ensnares Twilight in her influence, it's up to Pinkie to make things right.

This is the second story in The Petriculture Cycle. There is a TV Tropes Page for the entire Cycle here.

In an effort to keep her mind occupied, Twilight Sparkle decides to delve once again into the grand mysteries of Pinkie Pie. This time, Twilight's focus is on her claims of growing up on a rock farm: like so many things related to Pinkie Pie, the idea that somepony could grow rocks as an agricultural product makes absolutely no sense. However, the investigation eventually leads Twilight to a rather... surprising discovery.

This is the first story in The Petriculture Cycle.
