Inspired by "your human and you" by MadMaxtheBlack and the Percy Jackson Universe( it is not necessary to have read the percy jackson books but it is recommended as this story draws a lot of elements from the books)

The ponies of equestria, alongside the rest of Equus, never really thought of humans as nothing more than savage animals that were incapable of intelligent thinking or common sense. They are merely tools to be used when needed or pets to be kept for their own amusement.

This is common knowledge.

So imagine her surprise when the princess of friendship, Twilight Sparkle, finds herself with a "normal" human capable not only of critical thinking and common sense, but of so much more.
Things that a normal human should never be capable of doing.

Things straight out of mythology.
It seems things are just getting started for our little alicorn princess.

Noah Castellanos, son of Thetis, hero of Olympus, and the greatest warrior alive since Achilles himself, finds himself stranded on an alien world after committing the ultimate sacrifice to save his world.
Now,confused and sold into slavery in a world where humans are no more intelligent than the common cattle and were ponies are the absolute authority, he must learn to survive long enough to find a way back home.

At least there isn't some big bad primordial entity pulling the strings behind the scenes to make his life a living hell this time right?
...
right?
