There was only one explanation. For all of it. All of the strange, erratic behavior. Her irrational fear of the sun. Her nocturnal habits of locking herself in in the dark and closing all the blinds. Wearing her sunglasses everywhere, even inside! It was time to invest in some silver, garlic, and a wooden stake.

Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

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.

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.

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 isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Princess Twilight Sparkle lay there in anguished silence for almost a minute until she decided to let Scootaloo, Apple Bloom, and me help her. It came out as a whisper: "My special talent isn't magic." Of all the ponies we might help, I had never imagined our first might be Twilight, or that it would essential for Equestria that we got it right.

Thank you everypony!

Celestia finds herself sharing company and her booze stash with Luna's crazed split-personality, Nightmare-Moon. However, as the night wears on, she finds she may actually be able to tolerate the dark alicorn. Maybe even like her.

For Nightmare Moon is the best pony: Contest numero uno.

This story is a sequel to Split Second

Twelve years ago, she broke time. Two alternate timelines exist, each with a different version of Twilight Sparkle. Both versions of her are able to see the other. In this timeline, Sparkle is a Necromancer.

Or rather, she was. Sparkle is dead now, not that she cares. She's got a new body. With Thorn (her undead dragon son) and Cobalt (her apprentice and an assassin for hire) at her side, she's ready to take on the world. Again.

(Spoilers in the comments. Read at your own risk.)
