A former conman who traveled small town USA impersonating priests and stealing church funds before ditching and finding a new target. Unfortunately one small southern church he took over ended up being the location of a previously failed ritual to bring a Duke of Hell into the mortal world and into a new host body. Isaac accidentally completes the ritual and winds up tied to a demon who only calls itself Crow.     
    Unable to leave and unable to be exorcised from Crow, Isaac unwillingly becomes a demonic host and an actual priest of Hell. He is enamored with and married to the mysterious Ezra, who played an unwitting role in Isaac not being killed by the possession process.
