Set just before the events of chapter ten of Friendship is Optimal. One of the last living humans survives and scrapes by in the ruins of Eugene Oregon. He is approached by a simulacra of Twilight Sparkle, who promptly attempts to convince him to upload himself to Equestria. He balks at first, so Twilight plays to her strengths: studying.

Part of the Optimalverse.

WARNING: RATED TEEN FOR IDEOLOGY. This story attempts to take a realistic and balanced view of why an intelligent and religious person might not upload. It does not attempt to convince the reader to believe any of the viewpoints discussed. However, it is written in as unbiased a way as possible, therefore, both theists and atheists will probably find portions of it offensive.

Three friends who have fought together countless times have decided to retire from their lives as adventurers. They return to their home city and take up local jobs, they have lived this way for half a decade now. But their retirement from their youthful ways of adventuring is put to an end when they are tasked with a new goal from their leader, to find a cure for their people.

When Rainbow Dash's newest trick backfires spectacularly, she and Fluttershy find themselves stranded in the middle of nowhere. Together, they'll have to survive and find their way back to Equestria and Ponyville...no matter how far the journey.

After reading a book by Spitfire's personal trainer, Rainbow Dash decides that the best way to get closer to her ultimate goal of joining the Wonderbolts is to add strength training to her practices by having one of her friends ride her. However, when she decides that Twilight Sparkle is just the mare for the job, the pegasus gets a bit more than she bargained for.

Today's the day that Applejack is leaving to compete in the Equestria Rodeo, but something's... off. Derpy's been acting strange, even by her usual standards. Eh, it's probably nothing, right? After all, what are the chances that an eccentric mailpony behaving even more oddly than normal could ever be important in the grand scheme of things?

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.

Set in the Optimalverse, a middle-aged woman enamored of 'Equestria Online' confronts what permanent emigration to Equestria - uploading to a virtual existence - really means... but can she even hope to truly understand such a thing - and more importantly, can she trust the artificial intelligence known as 'Celestia'?
