Nosferatu: The Death Mass was published by Venus from 1997-1998
Two young women arrive at a creepy castle and are instructed not to go out to the graveyard lest some terrible evil befall them. The shadowy Nosferatu is lurking about, and begins to exert his strange control over the women, causing them to do his bidding.
Then, the adults-only nature of the series becomes clear as the women begin to fantasize about themselves and a platoon of female vampires, and the risen dead.
