The Quiet Kid choose to stay in Equestria for a two deliberately specific reasons. He needed a refuge from the problems of his world back home. And, his ability to summon up nearly any piece of military hardware he so wished in an instant required greater care than California, or really any human presence, could offer. Now, 2 years later, he unexpectedly wakes up back on Earth. Right in the middle of one of the largest cities on the West Coast of the United States. Not what he was expecting, but it could be worse.
Right? Right???
Well, he soon finds that this was not the earth he left behind. But rather something much, much more awkward and unsettling. He'll need to keep his wits together-and, with a little help from his alicorn companion, hopefully be able to escape the dystopian aberration he has found himself in and return to Equestria unscathed.
All one big joke, please take none of this seriously and or, personally.
