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.

(XCOM/FiM Crossover)

(Alternate Universe tag because of the divergence from canon that Stardust has caused)
(Uses elements of Season 4)
(Coverart produced by the amazing Carnelian!)

Celestia said it herself, that Twilight Sparkle is no longer her student. While wandering around in the city of Canterlot one day, Her Highness stumbles upon Trixie's local stage show. To Her Highness, there seemed to be much potential behind the mere performer's act, and soon found it hard to resist taking Trixie under her wing.

Would Trixie even be up to the challenge?

Slightly edited by NemoSpecific.

When a human appears in Equestria and is considered a threat, he is forced to flee from everything in the new land with nobody to help him while he is chased by colorfull ponies that want nothing but put him in a cage.

Megan Richards is a normal, everyday wife and published author of 'My Little Horsey'... however the tales she writes about aren't fiction, but stories from her past. She thought she put the world of ponies behind her, but sometimes the past has a habit of catching up with you...

G1 meets G4 in a hopefully epic tale of the past, the present and the future.

I own nothing, also, minor cameos from other Hasbro properties such as Jem and the Holograms, Transformers G1 and GI Joe.

Sequel: The Conversion Bureau: United We Stand

Side-stories and mini-arcs not able to fit into the main narrative: Side Stories of First Contact

This story is a sequel to The Elements of Harmony and the Savior of Worlds

The Conversion Bureaus have won. Humanity has been ponified, all traces of our civilization wiped clean from an Earth turned into Equestria. Princess Celestia rules over all, the tyranny of free thought abolished.

Humanity is at the cusp of a golden age. With allies both near and far, biped and quadruped, we strive for greatness, united as never before. Our mark shall be made in space, our influence felt throughout this Spiral Arm.

The Tyrant Princess sees this and is angered. A dome is opened... but this time, humanity is not alone against the Conversion Bureaus.

A spinoff/sequel to The Elements of Harmony and the Savior of Worlds, taking a place about a year after the events there, and my own little 'take' on the Conversion Bureau. This makes it a crossover with Transformers Generation One, GI Joe A Real American Hero and My Little Pony G1.

Thanks to Velkaden for the title. As well as Shubzilla for proofreading, the anti-Conversion Bureau for their help and SJC for help with the look of Megan.

Megan Williams had no big goals in life. Just to take over the family farm from her father. Then one day, her entire life is thrown into chaos when she finds herself transported to another world, full of magic and mythical creatures. A world where her very presence could threaten the precarious power balance that has existed for a millenia, for once there, she finds herself caught up in a political game of cat and mouse that threatens to plunge the world into war.

G1 MLP / G4 MLP Crossover

Special Thanks to Kevin Lee and Page-Mistress for their fantastic job of editing and proof reading.

Spin-off by Natomon01: Here

The friends we take for granted are often the ones that leave the largest impact on our lives. When Spike falls seriously ill with a mysterious disease and the ponies strive to nurse him back to health, Twilight Sparkle comes to grips with this very realization about her number one assistant--and friend.

EDIT: So this little story made it on Equestria Daily on 10/8/12. Now please excuse me while I pass out on Rarity's fainting couch while murmuring a soft Fluttershy "...yay."

Chris and Keon are two zoology majors that get separated from their class after following what Chris believed to be an undiscovered species of bird, during a trip into the Amazon rainforest.

Finding themselves stuck in a pit, they discover an ancient ruin adorned with murals and statues of what they believed to be ponies. They soon realize that the bird in question was the orchestrator of their fate, as they’re brought to what they are certain is their deaths.

Waking up, they are not only separated from each other, but in a new land entirely. Will they take this opportunity to learn about creatures only ever seen in legend, or will they be too busy being studied themselves?

Rated teen for sexual themes, crude humor, mild drug use.
