The various communities in Twilight overlap, intersect, and clash at times. There are the literal families, like Bella and her father. There are adoptive/created families. (Dr. Cullen made or found each of the other vampires, bringing them together for ethical companionship.) There is Forks, a small town where everyone knows everyone else's business, or thinks they do. There are shadowy suggestions of a larger vampire community, which operates like predatory animals staking out hunting territories. Finally, as old and mysterious to the people of Forks in its way as the vampire community, there is the native population. Somehow the Quileute Indians know about the vampires, and are watching over their presence among humanity.
