As Karen is now "marked" by the bite of a vampire, both he and Blade tell her to leave the city.Meanwhile, at a meeting of vampire elders, Frost, the leader of a faction of younger vampires, is rebuked for trying to incite war between vampires and humans. As Frost and his kind were not born as vampires and are therefore not pure-bloods, they are considered socially inferior. In response, Frost has one of the elders executed and strips the others of their authority.Upon returning to her apartment, Karen is attacked by a policeman, who is a "familiar", a human slave controlled by a vampire.
