A Star Trek Crossover
It was a long six months, but thankfully it was finally over. After an uneventful tour of duty patrolling the Tzenkethi DMZ, Lieutenant James Scott, Helmsman of the Akira-Class USS Juno Beach, was glad to be rotated off for three weeks shore leave.

En Route on the Shuttlecraft Nichola Goddard to the Trill Homeworld, there was a small mishap... Apparently Dark-Matter doesn't mix well with Matter/Anti-Matter Drive Cores.

Crash landing outside a small hamlet town inhabited by Ponies, a Starfleet Officer must find a way to make the best of thier situation.

In the year 2036 an asteroid dubbed "Apophis" struck the Earth and contaminated fifty percent of its water and atmosphere with an extraterrestrial pathogen dubbed "The SOL Strain." After two years, sixty percent of all human life was gone! With the world's governments struggling to keep their countries together; all seemed lost.

That is where my story begins.

My name is Chloe Cooper and I'm the only known human to be genetically immune to the SOL Virus. During the pandemic, I volunteered myself for experimentation. In order to keep me safe, I and three other humans were locked away in a vault deep within the Appalachian mountains. There these people, who I soon considered my friends, ran many tests on me and the virus, however after months without contact from above it was time to put the project to rest.

Cryostasis pods dubbed: "Cocoons" had been built in case we failed. 16,000 years later I awoke to sirens, signaling a whole host of problems.

And now? I'm the last of my kind.

Character tags will be updated depending on where the story goes

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.

The year is 2806, and Humanity has long left the loving embrace of their planet. After defeating the fanatical Enlightened, a warmongering alien race who had come to destroy them, many thought that an era of peace and prosperity was to come.

But that was not the case. Earth was lost in the war, and Humanity was divided.

A galactic civil war is raging in the galaxy, and three notorious pirates seeking to leave that life depart on a voyage to find the long-lost homeworld of Humanity: Earth. But complications arise as their destination is far more colourful, and far more occupied than originally expected…

Follow the tale of the Cerberus Pirates, and their struggles on a foreign world with nothing but the technology on their persons and the wreck of their ship to work with. Striving to get back to Mother Earth, and doing whatever it takes to achieve that goal.

When a young human super-soldier falls to Equestria, he must move on from his dark past filled with war, tragedy and bloodshed. Will he embrace this new chance at life, this new beginning? And most importantly. can he protect it when an ancient evil returns for a second time?

(NOT a Halo crossover.)

!!!Due to an incredibly busy schedule now that exams for college entry are closing in, New Beginnings is on Hiatus!!!

Twelve thousand years ago, humanity was driven into a war with an unknown enemy. Fire rained from the heavens and the sky turned dark as the sun dimmed. Acid poured from the clouds and a plague was unleashed upon mankind: A virus that caused men to turn on one another. A disease that forced man to fall to his knees and beg for mercy. A pathogen that ravaged man’s civilization.

And when humanity lost all chances of reconciliation, all hope of keeping their loved ones safe, they pulled the plug, three hundred souls left Earth while sacrificing their only home to the angel of the enemy.

In the twelve millennia since the Great War, all traces of humanity have been wiped from the surface of the Earth. In man’s rightful place now are a multitude of sapient species. For twelve thousand years, these animals have lived in peace and harmony, man reduced to nothing more than but a myth, a folk tale, a legend.

But word has spread across the countryside. Word of forgotten beasts that still walk the western wastelands. Creatures able to bend the world to their will without the help of magic. Creatures said to be older than time itself.

Teen for language, and dark moments. Character tags will be added as the story progresses
