Vampires are said to be mythological or folkloric beings who live by feeding on the blood of humans. 

Their recorded history dates back 4,000 years ago. There are supposedly three types of these vicious creatures: full-blood, half-blood, and demon blood vampires.

Full bloods are vampires that are completely of their race. They don't have a drop of any other kind of blood in them and they choose not to. These figures feed on any kind of blood, but especially, the young blood of children. They have many abilities, especially the ability to be immortal. In order to be immortal, they need to feed on a demon vampire's blood. Their weakness is the blood of half-bloods. They settle in among the humans, bearing perfect faces. However, they are too perfect. Flawless, pale skin, the fullest red lips, sharp but somehow trusting eyes: in  simple terms, they are beautiful. Common among vampires.

Half-bloods are half vampire, half human, like their namesake. They are usually formed when a full-blood and a human produce an offspring. Like full bloods, they have perfect faces, but they look more human than vampire. However, they are not immortal and can be killed just like a regular person will be. But they can't be attacked by full-bloods; that's their strength. They don't have a desire for blood unlike full and demon bloods, but they do like to eat meat. Very rare.

Last, but not least, are the demon bloods. These vampires are the ones that have lurked around since the start of vampire history. To this day, they still hide among humans. They are the most dangerous and is feared by everyone who knows of them. These creatures advance in power, strength, ability, and everything. They are also rumored to be the most vicious and cruel out there. But that's not all. Within seconds, they can turn from a human form to a vicious creature with eyes red as blood and fangs as sharp as swords. It is said that they kill everything in their path, vampires and humans alike. The only known way of slaying them is by letting them drink their own blood. It's like a poison to them. They are one group, consisting of only 15 vampires.

They are not so mythological now, huh?
