Fire, in addition to representing Malachi’s bloodline, represents passion, destruction, light, and other realms. When Malachi and Mina are intimate, but before he takes her virginity, he unintentionally creates “flames licking at the floorboards in almost a perfect circle around [them]” (47). Once they share powers, Mina does the same, unintentionally setting a fire when she orgasms. Wolf teases her about giving “Malachi grief for doing this very thing” (288).

Once Mina and her men have left Malachi’s prison, he uses his fire to destroy it. This can be compared to how Mina uses fire to destroy her father’s corpse. Fire represents not only destruction, but also defeating an abuser.

Mina is also able to use fire to offer literal illumination. When Azazel appears in Mina’s hotel room, she uses her power to create fire: “the flames are nowhere near as strong as I’ve summoned in the past, but they’re enough to break the unrelenting dark” (351). This is not a destructive fire, not a fire of passion, but a fire being used to see what’s in front of her. Fire represents the enlightenment of seeing Azazel’s true form.

Finally, Azazel describes fire as a symbol of the demon realm. Azazel calls Malachi a “fire-bringer. I’d like to see how you do in my realm, vampire. We demons can show you what true fire means” (295). Azazel alludes to, but doesn’t fully explain, how fire is a more potent and powerful tool in the demon realm.

Eyes represent emotional states. When Wolf has sex with Mina, it “makes crimson overtake the blue of his eyes” (428). Red eyes represent lust in Wolf. Rylan’s eyes turn “to a pure silver that looks otherworldly” (115) when he feeds from Mina. His pleasure is represented by silver. Malachi has “flames in his eyes” (47) when he uses his fire magic; the flames represent his power. When he feeds from and has sex with Mina, Malachi’s eyes go pure black, symbolizing his sexual abandonment.

Eyes are also windows to the soul. In contrast with Mina’s men, Azazel has “soulless dark eyes” (336). This implies that he lost his soul, or never had one, as a demon. Lizzie has “icy blue eyes. There’s no warmth, there, no soul” (436). She is a vampire who can set her own brother on fire, indicating her soullessness. Both their eyes turn red. Lizzie’s “flare crimson” (439) when she senses Mina’s power. Lizzie and Wolf share the same original eye color and color change because they are both part of the Radu family. Azazel’s “eyes flare red, not quite managing to keep things under wraps” (352) when he shifts from his monster form to his human form. In his case, red eyes represent his true nature and his anger. The eyes thus become a tool for reading moral alignment and emotional truth in a world where speech, especially Cornelius’s compulsive speech, can deceive.
