From the french game 'In Nomine Satanis/Magna Veritas', originally produced by Croc. The strange naming scheme is due to the fact that it came as a boxed set of two books; 'In Nomine Satanis', or 'In the Name of Satan' is the book for Demonic players, while 'Magna Veritas', whose translation I cannot recall, was for Angelic players. INS/MV was mostly a stab at catholisism, and includes Jesus as a Archangel, portrayed as The boss's son.
