Major Thomas Williams of NASA was wondering if he would ever get any further than Earth's orbit. Turns out he got quite a bit further than he expected.

A mysterious brown Earth pony with an hour glass Cutie Mark sneaks into Canterlot Castle, only to be caught by Princess Celestia herself. Curiously, Celestia is intrigued by the seemingly endless stream of nonsense this pony is wont to speak. Luna soon joins them, and the group heads into the very depths of the castle, where something has been lurking for far too long...

Author's Note: The story begins with Season 1 Luna, weakened and with very little magical power, as well as having 'flat' hair.

Doctor Whooves is also an Earth pony in this fanfic, as he has appeared as both a Pegasus and Earth pony in show.

Co-Authors: Bramble Rose, MudBug, Diomedes

When a experiment gone wrong lands a ruthless and powerful foe in the middle of Equestria, Twilight and her friends must put trust in a battered group of human soldiers if they are to stave off a revolution of the Bolshevik variety...

For little less than one thousand years, the species of Equestria had been a part of the Trade Order, sharing the millenium of peace of prosperity the humans had enjoyed.

Now, with the arrival of alien invaders and the return of ancient evils, that peace was been shattered. A people unused to war had to rediscover its ways and fight for their home. The Trader Emergency Coalition was born from this need.

Ten years have passed, and the sitation has improved to the point High Command has authorized a rotation of the forces, sending the weary first generation back to their homes, to rest and recover.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

So it was only a matter of time before Princess Celestia came to him with a job: keep Princess Luna company. Sounds easy enough, but as Sleepy Head interacts with the Queen of Night, he discovers secrets that will change his and Luna's life forever.

AUTHORS NOTE: Be aware that the shipping in this story could be classified as light-shipping or friend-shipping. I left the shipping tag out initially, but since the relationships between the characters are a big part of the story I felt compelled to add it. Also, a new summary is in the works, one that best shows the reader what to expect in this crazy fanfic.

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.
