The Kindred are humans infected with one of five strains of a mutagenic retrovirus called the Kindred Virus. Although they call themselves Kindred, they are commonly known as "vampires." Due to an anemia caused by genetic damage from the virus, vampires feed on the blood of uninfected humans. Vampires are known to mainly bite a victim's neck, extracting the blood from the carotid artery. They use the term "Kindred and Kine" to refer to all of humanity. The Kindred are also known for their enhanced physical capabilities, longevity, and lethal reaction to sunlight.
