A God's Day Off

This story follows a God of primordial chaos- the big man in charge of making sure everything is nice, random, and abiding by the laws of entropy. His name is incomprehensible to us mere mortals, so let's just call him Ian. The problem is, he's a bit too good at his job. So much so, that he incites his fellow gods into a sort of civil war. One that knocks him off the pantheon.
For good, it seemed.
But fellows like Ian aren't that easy to keep down. This is where the story comes in, see. Ian's simply going to do what he does best. Cause chaos, while forging his way up to his place on the pantheon.
