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 The Dresden Fillies: False Masks

It's been a while since the girls have seen their good friend Harry Dresden. Discord escaped, Luna attended her first Nightmare Night, the Royal Wedding was crashed by hordes of changelings, and Pinkie Pie threw a statistically improbable number of parties. They tried inviting Dresden, but between his new job and new apprentice, he always claimed to be too busy. The solution was obvious; if he couldn't come to his friends, they needed to go visit him. Besides, they say Earth is lovely this time of year. What could go wrong?

This, is Berk. Well, you can’t see it right now, but Berk is a beautiful place, full of life. Vikings and Dragons living together in a harmony that no one knew could ever have existed. Yet this story isn’t about Berk; this is a story about Toothless and I, as well as a few new friends. A story about a journey that began as a routine flight, and turned into something of legend.

This is our story about crossing The Divide.

A How To Train Your Dragon crossover written in collaboration with my awesome editor AuthorGenesis. Give him some love, considering this is as much his as it is mine, if not more.

And now pre-read by the fantastic Doctor Candor!

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.

Wilfred Xavier Manning is an exemplary clerk. However, he is somewhat less qualified to deliver invitations. Especially when the recipients are six of the strangest girls he has ever met. Such a minor detail means nothing to a man with Wilfred's sense of duty, yet still waters run deep. There is more to each girl than there appears, and if Wilfred is brave enough, there may be more to him as well.

Ninety six years ago, before the return of Nightmare Moon, a strange alien exploration probe landed on the world of Mundus, on the continent of Equestria. Uniting efforts, the griffons, ponies, zebras and minotaurs cracked the probe and shared the spoils with one another. Advanced technologies were found, advanced technologies that kick-started the Industrial Revolution of Mundus. The races lived together in harmony, and a new age of prosperity descended upon the world.

Regretfully, they did not heed the warnings that came with as much as they should have. Warnings from a long lost race once called 'Humanity'. Warnings of the Ethereals, and their mad plan. They did not train their armies, prepare their peoples, refine their technologies with speed and fervour. All that was done was the creation of a pact. A pact, and the XCOM Project.

Six years after the return of Nightmare Moon and Princess Luna, the Ethereals have arrived. In response, XCOM has been reactivated, as dictated by pacts almost a hundred years old. They know of mankind's struggles. They know of mankind's mistakes. But will they find victory where countless others have found failure? Only one thing is certain.

The Enemy has Advanced.

This story is a sequel to Stardust

When Equestria’s newest member of royalty asks for aid to be offered to her friends from abroad, the best and the brightest volunteer to serve. Captain Steel Song of the Dusk Guard are immediately mobilized to help XCOM defend their world from the enemies that besiege them. However, their first joint operation with the humans takes a turn for the worse and they quickly find themselves fighting for their lives against the full force of the monsters that threaten Earth.

Please READ the description first:
This story is indeed AU, though not by a whole lot, less as AU as my previous Stargate crossover. Hope you enjoy the past 6 weeks of toiling...

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."
