He filed 101 support tickets. The System turned him into a demon. Kairon is a system clerk who finally gets his own city charter. He does what any good bureaucrat would: reads the entire Terms of Service, finds a loophole, and exploits it. Unfortunately, doing so calls down a pillar of hellfire that roasts him, his villagers, and everything within a league. Now he's a demon with ten confused imps, a giant tower with a floating eyeball, and a rudimentary system that tears buildings through rends in reality — while a theocratic empire prepares to hunt him down.
