Shadowhunters, also known as Nephilim, are a secretive race of humans born with angelic blood. They are a demon hunting race that has survived for over one thousand years. They have fought the demons valiantly, creating their own culture and civilization within human society. Their mandate is to protect humans.
Above is the original meaning of Shadowhunters. On this site, however, instead of fighting demons, we live at peace and we have wolves in our ranks as well as the Nephilim. More info on Wolves and humans in the "Partners" topic.
