Werewolves

There are many who say the moon holds some kind of power over us, hence the word lunacy. Which means, periodic insanity thought to be caused by the phases of the moon. Which leads us to our topic, the werewolf.What are these creatures and why do they fascinate us.
The werewolf, can also be called Lycanthrope from the greek word lukos. There a human who can transform into a wolf or wolf-like creature. Said to be changed by a full moon and die by a silver bullet.
The werewolf has been in many folklore stories, and even in modern day horror films. In the middle ages the church stigmatized the wolf as the personification of evil or a servant of Satan himself.
I believe there is no answer, and that is what makes the stories and movies so great. We will always wonder.
