Caine's childer are called "The Damned," and no
  vampires embody this more than do the wretches of Clan
  Nosferatu. While other vampires still look human and may
  travel in mortal society, Nosferatu are twisted and deformed
  by the curse of vampirism. To put it bluntly, the Embrace
  transforms them into hideous monsters. Unable to walk
  among humans, Nosferatu must dwell in subterranean
  sewers and catacombs. Other vampires revile Nosferatu,
  considering them disgusting and interacting with them only
  when they must.
        Because of this stigma, however, Nosferatu are
  survivors par excellence. Few creatures, mortal or vampire,
  know the city's back alleys and dark corners like the
  Nosferatu do. Additionally, Nosferatu have refined the crafts
  of sneaking and eavesdropping to fine arts; if anyone or
  anything has the latest dirt on mortal or vampiric society, it is
  the Nosferatu. Finally, millennia of shared deformity and
  abuse have fostered strong bonds among the monsters.
  Nosferatu forego the squabbling and feuds ubiquitous to the
  other clans, preferring to work in unison. You mess with one,
  you mess with 'em all - and that can get messy indeed.
