Can the mane six discover calculus fast enough to win a flying competition, counter a deadly parasite, and destroy a tornado?

Welcome to the only MLP fanfiction which doubles as a calculus tutorial.

Once this fic is complete, it will serve as a complete walkthrough for calculus. I want to teach the intuitive side of math: tell you why things work, and make you feel like you could have discovered them yourself.

Petition your teacher to make this your school's standard textbook.

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

Twilight Sparkle finds herself inside a cocoon in the throne room of Canterlot Palace along with her friends and many other ponies. She is thrust into a dream world by Chrysalis who is feeding on the feelings of love and friendship she and the others will experience in their alternate realities. In her dream, she finds Princess Celestia, who has been able to cross between dream worlds. Twilight and Celestia must now travel between dreams in order to awaken their friends and stop Chrysalis. However, some dreams are not as happy as they expected, and some secrets held in the subconscious may be better left unawoken.

Now a comic illustrated by Zoarvek! http://zoarvek.deviantart.com/gallery/48143295

"Sex" tag added on 10/12/2014 due to sexual themes here and there. It's not the focus of the story, but it's in there. For a more detailed explanation of why the tag was finally added, see the author's note on "Corruption Ch 10"

Twilight still isn't having a very good day. An army of changelings is attacking Canterlot, and the experimental spell that blew up in her face has stuck her in a time loop until she gets everything perfect and saves Equestria.

She's got a plan. She's also got a problem: Suddenly, she's not the only one whose day is repeating. And when you're caught between unstoppable force and immovable object, life has a tendency to get complicated.

* * *

This story is an authorized alternate-universe re-imagining of Eakin's Hard Reset, in which multiple loopers turn the time shenanigans up to 11. (Knowledge of Hard Reset is not required, but based on reader comments, will help in sorting out the early chapters.)

Cliff's Notes versions: RampantArcana has started a GitHub repository to codify the time-loop rules and the early-story timeline. Hawthornbunny has posted a chapter-by-chapter breakdown of all the loops, including the ones we don't see, with a lot of critical analysis. Those links contain spoilers (of currently posted chapters). If you're confused, either one of those fan projects is a great starting point, and story comments have a lot of insightful discussion as well.

Publication schedule: 2014 kicked my plot, but as of November I'm picking up the writing again and hope to have something by the end of the month.

Cover art by Alexstrazsa.

Equestria stands on the brink of ruin. A necromancer has raised an army of the dead and is poised to plunge the world into darkness. Monsters and brigands roam freely across the land, preying upon the innocent.

Only one hope remains. Armed with swords, spells, snacks, and a bag of dice, five heroes band together to defeat the forces of evil… if their rolls are good enough.

Welcome to gaming night in Ponyville.

Dramatic reading by Goombasa.

Cover image by Elosande used with permission.

The Professor finds a strange, invisible object with the Smelloscope, and intends on taking the ship there to investigate and make observations. But, when they reach the object, something strange in the atmosphere crashes their ship, and they're now stuck in a world filled with colorful, magical ponies. The Professor must rebuild the ship to get back to New New York to continue business, while the rest of the gang is trying to cope with life on the new planet for the time being.

Because everyone loves Futurama.

Twilove for the awesome cover art! (She did a good job on that ship, if you ask me.)

The charming prequel to A Twilight Sparkle Story

The short tale of how I was trapped in a diabolical plot by a certain purple pony, and conclusive evidence that Twilight Sparkle may in fact be deranged.

This story is a sequel to A Twilight Sparkle Story

The story of Twilight Sparkle and her harrowing journey to Fluttershy's cottage, as narrated by the extraordinarily clever and handsome Discord.

Button Mash and Sweetie Belle decide to play Minecraft.

So of course, Minecraft decides to start spouting out of the computer and turning Button's house into hundreds of blocks, hostile mobs are spawning in his home and roam free, he has no idea when his mom is getting home, Sweetie Belle has no idea what she's doing, and as if that wasn't enough...

Button has absolutely no idea how to reverse this.

Totally normal day, right?

Inspired by the popular video Don't Mine at Night as well as a 90's movie called Jumanji while also paying homage to an 1879 opera called "Pirates of Penzance" in the form of an (attempted) song parody.

(Ahhh, this got put in the featured box, twice, Huzzah! Thanks to all my readers!)
