Although half vampires reach physical maturity at about the same age as humans, they are effectively immortal if they continue to consume the blood of mortals.

Treading between the worlds of the day and night, half vampires range greatly in alignment based on with which parent race their alliance lies. Those who lean towards their vampire heritage tend towards Lawful Evil, while those who embrace their humanity lean towards no particular alignment.
