Demons and humans are locked in endless struggle.

This is an intrinsic fact of nature. The demons believe their salvation lies in bleeding humanity of the life-force called light, while the humans are equally determined to defend it.

Within the sprawling empire of Lu-nevet, the two sides have settled into an uneasy peace, employing less violent tactics. But this peace can only hold for so long.

The state religion of Lukeira sends devout demon hunter Mitzli deep into the borderlands to bless the victims of demonic pranks. Once they arrive, however, they find unexpected signs of violence. They team up with irreligious hunter Veleiry to investigate-and the destruction the two uncover is an ominous sign of what's to come.

Meanwhile, shiftless demon Kor falls under the scrutiny of his vampiric commander, Mant-meaning he must actually do the work of tormenting humans, rather than taking credit from his now-ex-partner Yez. Slowly, he begins to realize that the demons' strategy is shifting, and may be heading down a path he cannot follow.

Mitzli and Kor will have to betray their respective factions if they want to put an end to the violence before it escalates. But the two of them, both outcasts among their own kind, are the only ones who know the truth. How can they protect the world if no one will listen?
