CLASS: VAMPIRIC

   These ancient annelid mutations are one of the few vampires that live socially, expanding their numbers to untold millions deep below the ground. They feed almost exclusively on degenerate, mindless sub-humans that they have bred for millenia, only rarely snatching fresh stock from the surface world.

  An Undercreep cut into pieces will almost instantly generate multiple new bodies, though all but one will wither and die by the following day.
