This story is a sequel to Pandelirium

Things have started to settle down since Twilight Sparkle and Pinkie Pie were crowned as princesses of Equestria, but that doesn't mean that any semblance of normalcy will be arriving. The first major summit of Equestria's ruling princesses is cut short when a thief steals the Element of Magic and escapes to another world. However, because of Pinkie's rather unique skillset, Celestia sends her to retrieve it, rather than Twilight. But even though the other Element-bearers will be staying behind, Pinkie won't have to face this task alone....

This story is a continuation of the plotline begun in The Petriculture Cycle. The first story can be found here.

ponies always seem to get themselves into.

Pinkie doesn't tell ponies about Pinkamena and Surprise. The doctors said that they were bad for her, that they were a disease, but she disagrees. Sure, Pinkamena's a bit of a grumpy-pants, but she's still a great friend! She's often the voice of reason to counter-act some of the other two's crazier ideas, after all. Surprise, on the other hand, is a great prank-player, and always up for some fun. She's more like Pinkie, only more hyper. Both are great fun to be around, and they get on well.

Thing is, she knows that if she told ponies about them, then they would be dragged back to the hospital. And then be 'treated' again. None of them want that. Because of this, not even her best not-in-head friends know about them. The three of them have, for years now, been careful enough to keep the existence of Pinkamena and Surprise secret.

This has, of course, gone out the window now that Twilight is hammering on the door after overhearing one third of a conversation, with no sign of anyone else talking.

Hints of F/F shipping inside. Nothing will actually come of it here, though. Maybe in a future story.

Deep in the Canterlot library, buried amongst the books detailing the exploits of a 'Doctor Whooves' are a few volumes regarding the pony whom they are based on. This is third or fourth of them (depending on whether or not one counts the one with the festive cover), and contains short episodes of Sepia Tock's life.

After the invention of radio, DJ-P0n3 (aka Vinyl Scratch) holds the first Equestrian talk show with her co-host Octavia. Octavia quickly finds out her superior is very eccentric, leading their broadcast to be constantly derailed, yet somehow remain popular. These episodes were recorded for historical significance and transcribed. These are the Vinyl Scratch Tapes.

[Update 1/25/13]: Fully updated to contain all of season 1 and 2, correcting a vast oversight on the part of the author. Sorry it took so long to update it fully on Fimfiction, guys.

This story is a sequel to π

After Twilight Sparkle made her biggest secret public much earlier than she'd originally planned, the lives of the Element-Bearers and their closest friends somehow managed to become even more complicated than they already were. Yet despite the flurry of all of the added activity this brings, Princess Celestia decides to undertake a particularly ambitious project: the reformation of Discord. She delegates the task to Penumbra Noctis, who, more than anypony else, can empathize with the draconequus' situation, and who is therefore best suited to showing Discord the magic of friendship. On the surface, it's a very reasonable plan.

Unfortunately, Discord has never had much patience for reason.

This is the fifth and final story in The Petriculture Cycle. Reading the first four stories, which begin here, is highly recommended.

This story is a sequel to Avocation

Life in Ponyville has been relatively quiet recently, which is somewhat surprising, given that the town's librarian tried to usurp the Equestrian throne only a few months ago. Aside from the appearance of a grumpy pegasus who set up shop as a cloudsmith, the aftermath is so unnoticeable that most ponies aren't even aware that the incident happened at all. Unfortunately, all that's about to change, thanks to the return of a certain revenge-obsessed showmare....

This is the fourth story in The Petriculture Cycle; reading the first three stories, which begin here, is highly recommended.

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