Vampires are mosquitolike insects about 6 feet tall at adulthood, with some of the most convincing capacity for superficial changing of appearance possible. They prefer to live in swamps and lakes, which likely lead to the archaic belief that they cannot cross running water. Vampires are omnivorous, with the aquatic larvae feeding mainly on plants and insects while the parents often choosing a much more diverse diet. Females have a biological need for blood in order to reproduce, preferring large mammals as their target. While Unaril and other Aldarthan sapients have certainly been attacked by them, this is largely overshadowed by their attacks on livestock.
