When Discord breaks free of his stone prison, he proves to be much older and wiser than he was on the show. A being of ancient and unimaginable power, he forces Celestia to make a deal to save her little ponies. What she doesn't realize is that one of the terms of the deal is that she forgets ever making it. Enter Navarone, a poor human just trying to get by—or at least, to the ponies that's what he looks like. Pulled from his home by an accidental summoning from one Twilight Sparkle, Navarone is thrust into a world of ponies and more violence than he expected from such a peaceful seeming world. These are his adventures—with a few asides from everybody's favorite Lord of Chaos, of course.

I make all the clop in this story skippable. But if you don't want to see it at all, I have it without clop on gdocs. But if you're a dirty heathen and you like clop, here's your version.
It feels unfair to spoil a story in the description, but a lot of people have asked for a warning about this, so the main character of my story eventually gets gender-swapped for a long duration.
