Sequel to the story Convergence.  

Two years have past since the portal between Earth and Equestria was destroyed.  With the complete cut off of all interaction between the two worlds, it seems that all would be well with Equestria.  The war has long since stopped, and the interactions with humanity, short though they may have been, have brought a great leap in technology.  However, something is brewing behind all of these peaceful happenings.  Something that will definitely make things a little... chaotic.  

Something sleeps in the Nevada desert.  Something that had been idle for a long, long time.  Then, one fateful day, thanks to a weapon test gone wrong, it is awoken, and the two worlds will never be the same.  Two men find themselves in the midst of a strange new world, and in the company of a species that is almost laughable.  All seems good at first, but quickly, they realize that some of their fellow humans have plans for the new world...  and the plans are anything but good.
