Yes, I understand that. I might have googled you Out of curiosity I did some research into the topic, including a tad bit into you, in the hopes of having a better understanding of exactly what you need in order to survive. Er, please feel free to look into my past, as well, if you like. I'm from a book called "Good Omens", as is Crowley. Please read it if you like, it's rather amusing, to be honest.
Well. It looks as if we shall have to choose between two evils, and as it seems that you aren't evil per se, then we shall have to allow you to feed off of very corrupt men with the admonishment that you won't feed off of anyone else. We can't very well have you starve, now can we? Although I am taking this moment to inform you that I am making all the requisite protests against this, and they're very strong, etc.
