@MartianWhile I'm still keen on playing Nyarlathotep, I have just realized that a figure such as Lucifer/Satan or Samael might have more of a reason to be on the council in the first place. That being human souls. Now I'm not sure what they'd do with them, maybe they eat them, maybe they use them as building material, or maybe they corrupt them to make more demons or just to spite whatever celestial powers that be, but nevertheless the devil would have a stronger motivation to make sure the council remains as it was before Dracula disappeared.
Plus he could have history with the old vampire given some interpretations of where Dracula got his powers from. Or, barring that, common ground in their hatred of God (who I imagine wouldn't be omnipotent in this and more just a powerful deity). I know there are issues with this power scaling wise and such, and we only get one character so I'd need to decide which idea to pursue more, but I just thought I'd mention it since Nyarlathotep's only real motivation is to start shit and cause chaos.
