Oh yes they do exist. They walk among us. I would know. Trust me...
So what exactly are Vampires? Well, they once were people like you. Then they underwent a change. Sometimes this is natural (for many reasons) and sometimes they make a choice. They grow fangs. Their bodies become clinically dead, and need blood to support the soul. The sun is lethal to MOST of them. Some adore garlic, silver stakes DON'T kill, and crosses don't do shit. Scare you?
VAMPIRES WILL NOT KILL THEIR PREY!! They have what's called a code. What?! THOSE THINGS HAVE MORALS?! Hell yes. Why do you thing they are still around? Some vamps only drink from willing prey, and they have their own version of vegitarians. Some vampires will not drink from a human, only animals such as sheep.
Vampires do, however, have an indefinete life span. Most live for several hundred years and never age a day. Therefore, they have to move frequently. Neighbors tend to notice when you stay 20 for 5 years...
