Vampire Safe Houses are buildings scattered randomly throughout Hungary where Vampires can go to hide from the sunlight, perform research experiments, or to torture Lycans for information. One Safe House is shown to be hidden in the woods, while another is in an abandoned building in the city. A network of computers connects all the Safe Houses to one another, and motion sensors make used Safe Houses appear under an 'Active' status should they be occupied. The Safe Houses contain large amounts of weapons and ammunition, as well as sophisticated computers that count down the time until dawn, among other things.
