Clary Fairchild: So what are you Shadowhunters?

Hodge Starkweather: We are sometimes called the Nephilim... In the Bible they were the offspring of humans and angels. The legend of the origin of Shadowhunters is that they were created more than a thousand years ago, when humans were being overrun by demon invasions from other worlds. A warlock summoned the Angel Raziel, who mixed some of his own blood with the blood of men in a cup, and gave it to those men to drink. Those who drank the Angel's blood became Shadowhunters, as did their children and their children's children. The cup thereafter was known as the Mortal Cup. Though the legend may not be fact, what is true is that through the years, when Shadowhunter ranks were depleted, it was always possible to create more Shadowhunters using the Cup.
