In a way, Darius brings the vampire back to a more classical interpretation. A modern day Dracula who is charming, sensual, and completely monstrous. There is no pretense of humanity with him. He considers himself a member of a species that is the true apex predator of the world, feeding on humans and using them as puppets for their own bizarre games. He's not struggling with any inner angst. Most humans are either food, entertainment, or useful tools to him. Sometimes all three. He finds the modern popular interpretation of vampires both amusing and useful for his own agenda.
