An omnipotent bring visits a land of tiny horses, and makes some adjustments to destiny.
In A Bored God, apprentice deity Rijalis is trapped on Earth for an eternity. Here, he goes to Equestria instead, and addresses some problems that the world's own creator had with making destiny run as she wanted. Even with omnipotence, things can get a little difficult for someone who isn't used to being a pony.
