Diaries of a Madman

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 with the devil-himself, of course-in order 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. Enter the poor human hero.
