The Legend of the Cold One

According the Twilight, the legends of the "Cold One" are described by Jacob Black as:

According to the Quileute legend, my grandfather made the treay that kept them off our land. The cold ones are the natural enemies of the wolf- well not the wolf really but the wolves who turn into men like our ancestors. You could call them werewolves. The cold ones are tradionally our enemies but this pack that came to our territory during my great-grandfathers time was different. They didnt hunt the way the others of their kind did- they werent to supposed to be dangerous to the tribe. So my great-grandfather made a truce with them. If they would promise to stay off our lands, we wouldnt expose them to the pale faces. They are always a risk for humans to be around the cold ones, even if they are civilized like this clan (the cullens). You never know when they might get too hungry to resis. They dont hunt humans, they prey on the blood of animals.
