Our hero, the Marty Stu, has been sent on by the djinn's magic to yet another reality in the Equestrian Multiverse. He awakens to see that once again, he is not a human, but some combination of man and snake. A Yuan-Ti perhaps. More annoyed by this outcome more than anything else, he decides to explore where he's been sent this time.
Another addition to the universe Rust and Blackwing created.
