Five years have passed since the final defeat of Ganon, and life has more or less returned to normal in Equestria. But the fragile peace does not last for long. Without warning, a portal to Hyrule opens up in the Everfree Forest. Sensing an opportunity, Princess Celestia drags Vaati and company to a diplomatic meeting to establish an alliance between Equestria and Hyrule.

But Vaati's return is met with open, fierce hostility, and the sorcerer is subjected to a trial that will doubtlessly be biased. But even as the people of Hyrule and Equestria debate Vaati's fate, the servants of Majora strike at last, and all the races of Hyrule and Equestria must make a bitter decision; unite against the powers of darkness, or be consumed by the evil of Majora.

The War of the Three Worlds has begun. It all ends here.

(I HAVE DECIDED TO REWRITE THE EWM SERIES. THIS IS THE OLD VERSION AND WILL NO LONGER BE UPDATED.)

This story is a sequel to Project: Sunflower

After the events of Project: Sunflower, Erin Olsen has returned to Ponyville, happy to pursue her studies in magic. After everything that happened the year before, she's looking forward to spending her days studying and having fun with her friends.

Meanwhile, on the newly discovered world of Harmony, humans and ponies work together to study this strange new world. However, their arrival causes something ancient to begin stirring. Something that may end up changing everything.

Erin will need all of her courage, all of her cleverness and, of course, all of her friends to see herself through what happens next.

Don't forget to check out the other part of the collab, Grey Hat

It has been one year since the invasion of Avol failed and the subsequent surrender of the dratali. Since then, the galaxy has seen peace like that which many had never seen. The races of Avol have been in negotiation with the races of the Alliance of Sapient Races. Now, Twilight Sparkle, her friends, and a few others are leaving their homeworld. While the others leave to forge a path in the stars for their fellow pony, Twilight returns to Earth with her boyfriend, Curt, to begin a project of her own; a guide to help ponies better adapt to very different culture.

Not long after their arrival on Earth, though, her plans take a dramatic turn. Between Curt's proposal to the discovery that humans have been developing magical abilities, the nightmare pony has her hooves full. No matter what, though, she was determined to come out on top, publish her book, teach a new race magic, marry the man of her dreams, and prove that even a nightmare's dreams can come true.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

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.

This story is a sequel to Pony Age: Origins

With the defeat of the Archdemon, Twilight Sparkle, new Arlessa of Amarethine, must assemble a new team of Grey Wardens to defeat the threat of the ponyspawn. Her friendships will be challenged by a cunning new foe while betrayal and deception lurks behind every corner.

Edit: Now a collaborative effort with Loyal2Luna

Commander Shepard has been through a lot, but now that the Reaper War's over he can finally relax and take a little R&R, right? Soak up the sun, grab a few drinks, spend some quality time with Tali, introduce a new race to the galaxy... wait, what?

In the aftermath of the war, a new species has been discovered amidst the destruction and fire. A species that have access to powers never seen before, powers which could prove vital to the continuation of galactic survival.

The Citadel Council has elected to send Shepard, along with the rest of the crew of the Normandy, to introduce Equestria to the universe outside of their solar system.

Now Shepard must wade through obstructive bureaucrats, antagonistic journalists, and the odd, angry prince in order to bring Equestria into a new age of space and adventure.

So settle in, it's going to be one hell of a vacation!

Now has it's own TvTropes page

Commander Shepard remembers firing the crucible. She remembers she had to make an important choice. She remembers good friends, a lover, and plenty of loyal crewmen.

She just can't remember what her choice was. What the threat she was striving so hard to end was. Or what the faces of the most important people in her life look like.

She also has no idea how she wound up in the monster filled forest she's come to call home for the past eight months. Or how she picked up a snarky A.I. making its home in her omni-tool.

The lost children...

Ten long years have passed since the Book of Darkness Incident. In those ten years, Equestria has come into its own as an allied world with the Time-Space Administration Bureau. Though diplomatic interactions between the two are still rocky, cultural, technological and academic sharing has helped to smooth over the bumpy relations to some degree.

In an attempt to foster better relations between the two worlds, the Bureau has established a special joint training task-force, bringing on some of the brightest and most talented mages in all of Equestria. A group of young humans, ponies, and... others have been selected as candidates for this new, experimental group.

Unfortunately for the humans and ponies of the Resolution Instructional Operations Task Force, things are not all they seem. A new threat is brewing; one that may destroy the fragile peace the Bureau has long sought to maintain... and dredge up secrets of a past long, long forgotten.
