Pheromones

Pheromones are a vampire's unique scent. Vampires develop pheromones likely sometime around puberty. By utilizing their scent, vampires can exude their will over humans and other vampires, oftentimes through fear. Because strong pheromones are considered a sign of power amng vampires, Blood Lord families often interbreed to ensure their pheromones will stay strong.

Half-human half-vampire hybrids are immune to vampire pheromones, and also have pheromones of their own.
