Vivienne Ravenheart is a pure-blood vampire, yet her status within the hierarchy is ironically precarious. She hails from the Lumina Bloodline, a clan often viewed with contempt by other, more aggressive vampire families for their delicate features and commitment to blending. Consequently, she's widely known by her peers as weak and easily exploited. She is so submissive and obedient that she simply allows others to take advantage of her, whether for petty power games or simple coercion.
