Vampire

Also known as 'vamphyri'. A mythical, undead, immortal, parasitic monster that feeds on the blood of living humans in order to animate itself. This is done via fangs, or the less-used method sucking the blood through the skin's pores. A single bite can transform the victim into a vampire. Vampires are unable to physically procreate as their bodies remain frozen in time from the moment they become 'undead'. Sunlight is a vampire's mortal (and on occasion fatal) enemy, as vampires are "creatures of the night". Vampires can be killed by sudden or prolonged exposure to sunlight, dismemberment, wooden stakes to the heart, and by fire. A stake must be put through the heart of a vampire's dead victim and their head must be severed from the body, or they return as full vampires. Vampires cannot enter a home without being invited in first. They have no reflection in mirrors. They also cannot cross running water (unless it is in their own homeland). Rumored to be weak against garlic, holy water, and crucifixes. Also rumored to have illusionary shapeshifting abilities as well as the power of flight, mind-reading and hypnosis. May or may not sleep upside down or in coffins.
