Well in this story, the demiwardens are a force made of minor gods made to monitor and arrest other gods who cause danger to mortals. They're basically like a fantasy FBI, military and police mixed together.
That one reminded me of the horror story I was considering. A story in which death is an actual entity (akin to Final Destination), but rather than using elaborate means to kill people, it would possess one person, kill a handful whose time was up, then when the currently possessed individual was sentenced to death, they'd jump to the next, rinse and repeat the process.
