It has been a hundred years since Equestria has registered with the Cornerian Army. During that time technology on Equestria has increased at an astronomical pace. New buildings, new vehicles and new species now walk with ponies.

But along with the new technology comes a promise. A promise for those who wish to leave Equestria and travel to the stars beyond. To explore the vastness of space and protect it from those that seek to do it harm.

Slipstream is the first of two ponies from Equestria to join the ranks of the Cornerian pilots. So she will be the first to see that the heavens are far more dangerous than any would have believed. That it is a place of criminals, thieves...and mercenaries.
