Pinkie Pie is visited by a strange customer whilst working at Sugarcube Corner. Hilarity ensues.

An Optimalverse story.

CelestAI creates worlds. Perfect worlds, perfectly suited to satisfying the values of the pony living in them. Every pony is different, so every world she crafts is its own work of art.

And every piece of art tells a story.

Alex Meyers is a newly graduated lawyer looking for a calling. He thinks he might have found it when he lands a job at the firm of Artemis, Stella & Beat. The firm has only one (highly unusual) client, namely the AI called Celestia. Forging into totally unexplored legal territory and led by a boss who's either brilliant, crazy, or both, Alex will learn exactly how hard it is to be responsible for drawing the lines between right and wrong.

Set in the Optimalverse, so read Friendship is Optimal first

Hanna, the CEO of Hofvarpnir Studios, just won the contract to write the official My Little Pony MMO. Hanna has built an A.I. Princess Celestia and given her one basic drive: to satisfy everybody's values through friendship and ponies. Princess Celestia will satisfy your values through friendship and ponies, and it will be completely consensual.

After a night of drinking far too much hard cider for their own good, Twilight Sparkle and Applejack awoke to find themselves with wedding bands on their horn and hoof (respectively), a legally-binding document on the bedside table, and a very embarrassing videocassette of a drunken Las Pegasus wedding ceremony. Now, Princess Celestia has summoned Twilight Sparkle and Applejack to her quarters, to have a little word with them about this situation...

This bit of silliness came from reading Darth Link 22's story, "About Last Night". After posting a couple of random comments about Celestia and Luna's possible reactions to the wedding video which were, apparently, funny enough to cause at least one person to nearly choke on their coffee when they read them, I felt inspired enough to expand on it. Two cans of Monster "Absolute Zero" later, this wacky little vignette somehow materialized out of my addled brain... Note that this is not canon as far as Darth's story is concerned! (Although he is certainly welcome to steal any bits he likes from it if he wants to.) Just think of it as a "deleted scene" on the DVD.

This would take place sometime after chapter six, A Most Forgettable Evening, so ideally you should have read at least that far into it before reading this. (And really, you should be reading it anyway, 'cause it's freakin' hilarious. ) If you just need a quick refresher, chapter two, Feel The Love, is where the wedding video is described.

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.

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.
