The Coroner is an Exile who, as his name implies, occupies himself with studying deceased individuals who have died mysteriously. It is presumed that he is doing that for his own purpose. He is one of the Merovingian's information sources. He lives in Baldwin Heights. He is the nemesis of Hypatia.
The Cypherites reached him in order to prevent the Merovingian from doing any harm to the sleeping humans with the data that the wealthy Exile had. However, he told them that his rival, Hypatia stole the information from him.
