Nictuku
According to Nosferatu lore, the Founder of their clan has two major bloodlines. The second bloodline, descended from a tribal priestess who escaped his hunt (hinted to be Babba Yaga), are the entirety of the modern Nosferatu clan and worth nothing more than extinction as far the elder is concerned. The agents of this extinction are the Nictuku, hideous creatures Blood bound to the Antediluvian and perpetually engaged in a crusade to wipe out the clan's strays.
The Nosferatu treat the Nictuku seriously; part of their fondness for sewers is because they build these underground havens into massive fortresses, complete with gun emplacements and embankments on the lower levels. The Nosferatu information exchange tools, up to and including SchreckNet are intended to exchange Nictuku sightings.
