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.

Something is gathering around the bearers of the Elements of Harmony. Something dangerous. Something magical. There's only one pony with the knowledge, the skills, and the muffins needed to save Equestria as we know it.
A Friendship is Magic: the Gathering crossover, taking place between seasons 1 and 2. Here there be flashbacks, briefly seen OC's, and possibly every emotion known to man or tiny horse. Abandon all pretenses of not being a nerd, ye who enter here.

Something has happened and Twilight finds herself in a strange and dark new world. The Bipeds here have strange magic, advanced technology, and a lot of problems. She needs a few friends, and they just might need her. WORM crossover. Deadpan29 has created some great supplementary material that is canon to the story.

Twilight Sparkle, Sunset Shimmer, and Moondancer are the top students in Celestia's School For Gifted Unicorns. One is a dedicated bookworm with a love of learning, other is an outcast full of ambition, while the last one just wants to enjoy life... a lot.

Connected with unlikely friendship, together, they fight crime live their lives, one day at a time.

(Sometimes they fight crime, too)

While it is set in Stallionverse, knowledge of previous stories is not required (you'll miss a joke or two at worst).

Teen rating and sex tag for slightly edgier humor, innuendos and Moondancer.

My own chapters are edited by the ever kind and generous Docontra, whose patience knows no bounds.

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.

After tiring of Twilight's hostile attitude, Discord decides to "help" the Elements of Harmony by bringing in an alternate version of each of them. These duplicates from various worlds aren't told anything about each other, which is good. The last thing Equestria needs is these monsters working together.

Derpy just wants to bring ponies their mail. She's not trying to save the world.

It's funny how things work out sometimes.

Wake up. Go to work. Save Ponyville from unimaginable horrors beyond time and space. Have lunch with your PFF.

Ditzy Doo lives in a different world than her fellow ponies. She sees things nopony else can see—like higher-dimensional spatial anomalies, fae creatures, and eldritch abominations. And she uses what she sees to solve problems that nopony else even knows about.

But this time, Ditzy may have bitten off more than she can chew. Something very unfriendly is trying to enter Equestria through Ponyville’s Town Hall. An earth pony with an hourglass cutie mark has taken an unhelpful interest in Ditzy. The Princess’s personal student has grown suspicious. And, most irritating of all, her alarm clock radio is acting strangely.

Ditzy must race against the clock to save Ponyville—a clock that keeps playing the same song over, and over, and over ...
