The vampire as a race are divided into two types. The Vampire Lords who are far more powerful, as well as exhibiting average to superior intelligence. Then you have the Vampire Underlings who are weaker, as a result of feeding off of humanoid beings, as opposed to the Lords, who fed solely on other demons. Underlings will make similarly weak vampires, while a Lord will make stronger vampires. Vampire Lords who feed off of mortals risk weakening, but they are capable of turning them with little issue. Underlings commonly serve Lords, often corralling creatures, as cattle to be fed on by themselves, and the Vampire Lords. They do not consume souls, but they often refuse to consume of the blood of something that does not have one. The only documented cure to Vampirism is Resurrection.
