Well don't assume that for a few reasons! :P

*Vampire society is fractured. No one rules it. The remaining clans war with each other, external forces and are divided by deadly internal politics. The other players [u]are not your allies[/u] and even those that pick the same bloodline may betray you. The only thing that will keep characters from each others throats is the threat of having their hearts obliterated by unseen hands.
*There are no 'purebred vampires'. Of the Five Houses only three remain (Vetala, Draug and Alp), while Dhampir are afflicted with a blood-thirst they don't really count, as they're merely vampires that haven't come into their curse yet. Dhampir that live long enough eventually become one of the other flavors of vamp.

On a side note I'll be avoiding the muscles are meaningless trope, so don't expect to be superhumanly strong.

In a nutshell it's probably best to leave most preconceptions at the door.
