Werewolf

A Werewolf is human who changes into a wolf-creature every full moon. Even when they are not in wolf form they are more powerful than ordinary humans. They are also arch enemies of the vampires.

Even thought werewolves are able to breed the powers cannot be inherited. Only through a bit can a human become a werewolf.

Creation
Creating a new werewolf is easy and yet dangerous.

An already turned werewolf must bite the human. In a werewolf's bite is a toxic that is ment to kill the pray but when it comes in contact with human blood it mutates the human's DNA instead of killing it.

It takes about a month (from full moon to full moon) for the poison to mutate the DNA. And the final step is for the new werewolf to transform for the first time (this happens under the first full moon after being bitten).

But if the human is too weak the poison will kill them. The death of a bitten human can happen anytime doing the month. If the bitten survives the month out and transformer at full moon its out of danger of dying from the poison.

Cure
There is no known cure for being a werewolf except death by decapitation. When first bitten by a werewolf the human will either turn into one itself or die from the poison.

Origin
In an atempt to create more Archdemons, one of the seven Arcdemons, Death, feed her blood to the humans Quinn and Amara doing full moon which turned them both into wolf-like creatures. Inspired by them being half wolf and half human Death call them werewolves. Werewolves were the first of the werebeasts.

Later in life Quinn and Amara had four children: Two sons and two daughters. At their 18th Birthday their parents turned them into werewolves. The four children became the founders of the four original werewolf families: De Were Family, Van Helsing Family, Blood and La Luna.
