For werewolves, a clan is different from a family, although clan affiliation does tend to run in families, passed down from one werewolf generation to another. But a clan is actually a group of like-minded werewolves with many shared interests and a shared purpose who trains, hunts and hangs out together on a regular basis.
Each clan has its own moon. Some werewolves think that it is the moon itself that gives each werewolf his or her powers and characteristics, but many more werewolves believe that while the moon of your first transformation may contribute to your character, that both your character and your clan affiliation are more a matter of choice and training.
However, it is indisputable that each clan claims a different moon of the year. Many clans will initiate new members on this moon and some of these rituals are super secret.
Some clans actively recruit new members but other clans are more secretive, they require new recruits to find them.
There are 12 main werewolf clans active around the world who agreed to be listed on this site. In fact there are many more secret clans and in time hopefully these clans will agree to let themselves be known to the world. But until they do, you can find more information about the twelve main clans here on the site and consider which clan you might like to join, if you get the chance.
