Why I Didn't Save Anyone

That spoon proves who he is,
But if Hat lets him keep it, he could kill everyone.
Reeling from the aftermath of a terrible but ultimately necessary act, Hat, the assistant of a fantasy author, figures out just the right thing to do to fix everything. But then he just has to go and take that nap.
Waking up in the world his boss writes about, Hat encounters a naïve young man with a spoon of incredible power whom he soon realizes is one of the most important figures in the history of that world. However, the man is not what Hat expects, and his attempts at greatness often end disastrously.
Should Hat intervene and risk changing the history of his favorite world or should he let his foolish new friend continue to make mistakes that could destroy everything he loves?
