Vampires. A common myth. A hoax. A tale that was started during the dark ages to give something that a common Human could not understand a meaning.
Or is it just a myth? How do you we know whether these myths were told as a mere fairy tales or as a warning? To keep curious or mischievous children from going missing at night? To explain the unknown?
What if they were told to the Humans by the unknown? To find entertainment. To tempt the brave souls who dare try to disobey the rules? But, how could the unknown creatures of the night tell the Humans? Dreams? Signs? Messages? . . . In Person? Yes. That's right, in person around a warm fire on a cool summers night. But how? Anyone in their right mind would run off screaming, alerting the village. But yet, they didn't.
It was because these creatures, Vampires as you may call them, are among you. Everywhere. How? Because they look like you and I. They look Human.
They have reflections, they can go outside on sunny days. They can look and act Human without being suspected. That is why they're dangerous. They can feed, kill, and turn Humans into Vampires at any convenient time because no one suspects.
In the 21st century, blending in is easier than blending in during the dark ages. Your boss, your friend, your friends friend, your roommate, your teacher – all of them could be a Vampire.
That is also how they hide. How they hide from the people, the Humans, who know their weakness. Humans who can figure them out just by glancing at them.
The Humans who hunt them.
