After graduating from the Artificers' Academy that he has studied at since he was a child, Miles Nummer dreams of using his knowledge to help people. Instead a chance encounter with a church archon leaves him hopelessly entangled with a plot to destroy the heart of the society he lives in.

            Miles Nummer is an artificer, born with the ability to blend science and magic. After ten years of study in the artificer's academy he is ready to make his mark on the world. But after being saved from a mob by a beautiful young archon named Sophia Meisters, a soldier blessed with divine powers in the service of the church, the two of them soon find their paths interconnected as the murder of an angel leads to the discovery of a conspiracy to destroy both the church and the government that it supports.

            Now they must race against time to unravel a plot involving demons, homunculi, and illegal technology that could destroy the world in the wrong hands, and all the while every clue seems to point to Miles' own mentor being the one behind it all.
