Vampire

Vampires (Homo nocturnus) are a species indigenous to Earth, closely related to humans.

Mythology and Origins
Vampire mythology has diverged much more from clan to clan than teryo mythology has, but reconstructions tell us that the original vampire mythology said they originated from the eruption of Mount Toba in Indonesia around 70,000 years ago, which nearly wiped out Homo sapiens.

The story goes that the lava flows encased some humans, who were mummified in the debris and awoke hundreds of years later, feeding on humans and teryo at night, and infecting and interbreeding to create new vampires and spread around the world.

Society
Vampire society is dominated by a system of clans, which are more like nations instead of a familial group like teryo packs. Each clan is ruled by a king or queen. Due to their noctural nature and historic persecution, vampire clans have historically operated in the underworld of human society, engaging in crime and subsisting at the expense of humans. Some clans have tried to integrate themselves into human society, to become more accepted. Others have embraced the underworld further and become more like gangs.

Diet
Vampires need mammalian blood to survive, like humans need water. They do not need to eat or drink anything else, but many do just for pleasure. Historically, vampires have been nocturnal pack hunters, feeding on whatever mammal they can find, including humans. Today, most vampires subsist on cow or pig blood bought at a store, but some 'traditionalists' still hunt for human blood.
