Seritues sits atop the most powerful empire in history, built upon the creation and enslavement of a magical species. Known as the kosar, they are bound to live in harmony with humans and serve without question. But the empire is thrown into disarray when a kosar is accused of murder.

Seritues’s mistrust of their species leaves him the only person willing to investigate this great atrocity. The fate of the entire empire rests on his investigation and the senates’ ability to maintain unilateral control of the kosar.
