The werewolf origin is a half-truth, the story told is an embezzled tale that old wives and grannies tell their children and grandchildren so they have pride in what they are. The story is that an old woman who was a devout pagan gave the last bit of her life to a moon spirit in need. The moon spirit rewarded this woman with internal life, but at a cost. This woman will need to devout three days of each month to the moon as one of nature's creatures: a wolf.

This is still mostly true today, during the full moon the urge to change is extremely strong. Typically only elders are able to resist the urge to shift. This desire is a buildup as the moon waxes from the new moon to a full moon. The desire disappears as the moon wanes from a full moon to a new moon. 

A werewolf is only created two ways, however, one way is considered taboo. A werewolf can be born, from either both parents being werewolf, or a werewolf and human parents. They are not considered hybrids as the werewolf gene typically takes complete control. The other ways is through biting another, however, this is can be extremely lethal as a werewolf bite contains massive amounts of poison. This poison can either kill a human or turn a human into a werewolf. Vampires are not effected by this poison, as their own nullifies the toxins.

Werewolves take the appearance as normal wolves, except they are typically taller, longer canines, longer claws, and have the ability to command regular wolves. They can have special markings, nothing too extreme, they also have normal fur colors, and normal eye colors.

In human forms, typically they will have the ability to grow muscle mass faster than normal humans, they are also able to run faster, jump higher, and are stronger than normal humans.

Werewolves tend to form very strong familial bonds, with pretty much anything. Pets they have, friends, cars, plants, you name it they can get attached to it. These bonds are coded within their genes to help protect them from outsiders but also to carry on the werewolf line. 

Unlike vampire houses where each one has a specific power based off the original founder, werewolf packs have specific, almost witch-like abilities. They are typically more inclined towards nature, the elements, and other natural means. 

Werewolves have similar weaknesses to Vampires do, such as silver, iron, decapitation, and removal of the heart. But they are also weak to wolfs-bane, and lack of nature. If they live within a city, such as New York, and are around very little plant life, they will soon grow extremely weak and some are known to loose touch with their wolf side all together. Not a cure, as they slowly wither and die afterwards.
