The gang have run across a few vampires in and around Murfreesboro. Leroy recently killed a couple of pretty powerful ones that had set up house in his hometown and had been feeding from his father and sister.
Vampires are created when a vampire kills a human - allowing a vampire-demon to take over the victims body, taking the place previously held by the persons soul.
For the most part they can pass as human, but when the are engaged in deadly combat they "Vamp-Face" - at which time they have fangs, yellow eyes, and a brow ridge.
They possess superhuman strength, toughness, speed, and invulnerability to most damage.
Vampires can be killed by being staked in the heart, decapitation, and possibly through fire. Holy water can burn them like acid and a cross can sear them like a branding iron. They are severly damaged by direct sunlight and can not come into a home unless invited by someone who lives there.
