Princess Twilight Sparkle has died a hero, but no one knows why.

Between an ancient evil that had not even existed until she struck it down, a mysterious crystal ball that bears some unknown significance, and a set of cryptic notes and behaviors from the princess during her final days, the circumstances behind it all are murky at best and suspect at worst.

And the rabbit hole only grows deeper from there.

The Crystal Ball Trilogy is a series of stories which deal with time travel, parallel universes, and other manipulations of time and space. Feedback is the first story; it is succeeded by Substitute and Divergence.

Twilight Sparkle may be a brilliant scientist, a flawless engineer, and a wielder of otherworldly magic—but she's not infallible. Sometimes, she isn't okay. Pinkie knows this.

Inspiration is Rarity's Element, and Sweetie Belle her greatest achievement. But the filly has questions, ones that Rarity might not be able to answer on her own. What makes a pony? How can somepony know if they really are alive? Are they alive if they laugh and cry? Are they alive if they think, if they make mistakes and have ideas?

If Sweetie Belle is nothing more than a collection of wires, is she truly alive?

It is the day of Nightmare Night. Everypony is busy with something to make sure the festival is going to be a success. Everypony except Twilight. Her job—crafting fireworks and keeping them at a safe place—was completed days ago. Unfortunately, she exaggerated the “safe” part a bit, as she lost her only way to get to them.

Will she get the fireworks in time for the festival? Well, that depends on your choices!

This is an interactive, “Choose Your Own Adventure!”-like story, where you get to decide what Twilight does next! (Further details are in Chapter 1.)

Note about the tags:
This story is, in theory, a Slice of Life. However, for you it is an Adventure. But as there isn't any tag that would come closer to “interactive story”, I had to pick this. A pre-reader I asked confirmed it was fine for this case.
Just so you won't get confused.

Okay, I don't know if anyone can hear this, or read this, or whatever, but I'm trying my best to use Pinkie Pie's legendary fourth-wall-breaking powers to try and get a message out.

If you can hear this, I need help. I'm in Equestria, and man, this is strange. But I'm also stuck in Pinkie Pie's body, for some reason.

Yes, it's just as weird as it sounds. And now, I need your help... because all the ponies in this town think I'm crazy!

A damaged robot pony, unlike anything ever seen in pre-industrial Equestria, is found in the orchard. Before it collapses, it says only two words: "Twilight Sparkle..."

Twilight fixes the mechanical mare and gives her a new directive: "Make friends." Now a robot must learn what it takes to be a good friend and, while she's at it, what it means to live...

Foals can do it, you can do it too! Miss Cheerilee points out some basic rules for all of her students to follow. (Note: rated teen for not having random sex scenes with Twilight Sparkle). Also, apologies to my editor Future, because I didn't run the story by him and he puts up with that sort of crap

(Also also, huge thanks to blackgryph0n *original artist* and Paleo Prints *the touch-ups* for letting me use their fine cover picture!)

Luna is on her way to visit Celestia, but hears her squealing for someone to 'stop!'

She walks in on Twilight on top of a red-faced Celestia, and the two of them react like guilty teenagers. Just what the buck is going on here?!

Sandbar is excited because he just won six tickets to the Buckball World Series in Fillydelphia. After informing his friends of this great news, he proceeds to talk about the Fillydelphia Fillies, which includes telling them the names of the players.
That's when things get complicated.
Based on Abbott & Costello's Who's On First? comedy routine

It is astounding what one can accomplish over breakfast. Breaking the laws of reality wasn't quite what Rainbow Dash had in mind during this particular brunch. She wasn't really in the mood for a lecture on the matter, either, but Twilight was eager to provide one.

Warning for chaos, breakfast foods, and the general nonsense that comes with writing absolute madness.

Thank you to Cynewulf and Axolu for taking my silliness seriously. Very seriously.

Featured on 11/27! Thank you all so much!
