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.

Twilight Sparkle is a gifted student and scholar. When she attempts to harness her creative side by writing a science-themed sensual romance novel, however, things rapidly get out of hoof. Can her friends stage an intervention before she humiliates herself (and them) at a prestigious literature recital?

No. No, they cannot.

"It's called 'Shh'," said Fluttershy. "It's a game about who can be quiet the longest. Sound fun? I'm the world champion."

Fluttershy is not a pony who makes things up. She really is the world champion of "Shh," or The Quiet Game. And now it's time for her to defend her crown, with Twilight Sparkle and Rarity along for the ride.

We all wear a mask called composure, beneath which hides a heart that twists with guilt and hidden feelings. Regal as she is, Princess Celestia is no exception. What might be revealed should circumstances cause this mask to slip - or break?

Set several years after the potential conclusion to the series.

This is the story of the end. This is the story of the death of Equestria. It is the story of the reign of her royal majesty, Princess Twilight Sparkle of the Fading Sun.

The alicorn sisters are dead and Equestria has turned to Twilight Sparkle to guide it. However, just maintaining a dim sun a fraction as bright as her mentor's keeps the new princess near her limits.

Years have passed and Twilight Sparkle is sure of only one thing. Equestria is dying.

NOTE: Written before "It's about Time" in season 2. Everything after "Read it and Weep" was ignored throughout this story.

Rainy weather and a looming deadline drive Twilight Sparkle up the walls and Spike out of the tree. Only Pinkie Pie can save the day, by introducing the reluctant librarian to an unexpected new hobby. Astoundingly, sex does not ensue.

It's been a few weeks since Luna's returned from the moon, and all is not well. She's become more introverted than ever, rarely leaving her room and obsessing over work. Celestia hopes that studying Twilight Sparkle's Friendship Reports will at least help her get out of her shell, though an unusually talkative servant may just help in that regard...and is anypony else getting strange feelings from that statue out in the gardens?

As of May 4th, now featured on Equestria Daily. *Squee*

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!
