Vampires are anti-life, or Tactus disvitae. They feed off the magic potential, including the vestigia, of their surroundings and of living creatures.
At one point DCI Nightingale and Peter Grant went to a seemingly abandoned house in Purley. They encountered a family of vampires in the basement, and used phosphorous grenades to annihilate the vampires.
