What happens when one is embraced?
First one is killed, most usually by being drained of all blood. Then, some of our sire's blood is introduced to us and begins its metamorphosis. I believe the power of the blood somehow traps our spirit like a fly in amber, somewhere between here and the hereafter. Hence we are dead, but do not rot, and this is why we must feast on the blood of others in order to extract their life-force to feed on.
Our heart does not beat, our organs wither and die, our bodies change and so does our mind. The potentials of our old human shells are overwritten and expanded. We go beyond human, like a butterfly from a caterpillar, we are so much more and so different than that which we come from.
Humans are omnivorous, eating plant and animal matter. We are carnivores, indeed parasites, feasting on one thing and one thing alone. Blood.
Humans form pair bonds to mate in order to produce children and for pleasure. We reproduce without sex, we have no need of anyone but ourselves and most gain pleasure only from feeding and the taste of blood. Those who claim to still derive pleasure from sex are either mad, or haven't yet cast aside all their human foibles. Sex is a barrier, they are trying to say "Look, I still enjoy the human things in life!" But this is a dangerous sham.
Humans are diurnal, we are nocturnal. Indeed the very presence of the sun is deadly to us, more so than to any other creature on the face of the planet.
Humans abilities are pretty much standard, one can do the same as any other pretty much. Our abilities differ from Vampire to vampire and go beyond what is possible in the natural world.
We are not human. Do not pretend to be. This does not mean giving up morality, art, beauty, it just calls for a recognition of who and what we are, and that is not human. To hold ourselves to a stylised morality that even true humans do not keep to is laughable. We need a new morality just for us. The word of Cain carries most of that message. The humans are prey, but this does not mean we cannot like or respect them, honour them even. After all, we came from them.
