Domini, a human woman marked as a sacrificial offering to Satan by a Boston-based cult, is abducted mid-ritual by Dracula, who defies his predatory instincts upon encountering her. Captivated by her beauty, he spares her life, forging an unexpected emotional bond that alters his behavior. Their connection deepens into a romantic union, culminating in the birth of their son, Janus. This familial tie softens Dracula’s vampiric ruthlessness, driving him to seek an uncharacteristic domestic peace.

Their fragile stability collapses when vengeful Satanists murder Janus, a loss that devastates both parents. The child is resurrected temporarily as an ethereal being with angelic traits and luminous powers before reverting to infancy. Domini’s presence intensifies Dracula’s internal clash between his monstrous identity and a newfound longing for mortality. Her involvement attracts threats from Satan—enraged by the stolen sacrifice—and vampire hunters intent on destroying Dracula. While her role centers on sustaining these relationships, the narrative omits her history before the ritual and any autonomous goals outside her ties to Dracula and Janus, leaving her agency unexplored beyond familial devotion.
