Nosferatu

Blood of the Nosferatu is twisted and ugly, which carries over to their outward appearance. Many Nosferatu are immediately recognizable as vampires, and as such are unable to openly live in society without much difficulty. Those of this bloodline are often adept rogues, slinking through the dingiest parts of cities and towns to garner information or smuggle goods. There are, however, a rare few of the Nosferatu blood that become more monstrous not just in appearance, but temper as well.
