Vampire Physiology

Vampires, during the process of being embraced, have the internals of their internal organs wither away until the inside of each organ is empty. If the organ is not connected to the circulatory system, it becomes merged with it or withers away, results varying inconsistently. After the sire of the fledgling vampire releases them, the fledgling falls into a brief slumber, lasting from a few seconds for the more powerful vampires, to a few minutes. As a result, their entire body is filled with blood, like a living jar of blood, replacing all their bodily fluids. Vampires cannot eat, as they have no internal organs to digest solid food.

Blood runs a vampire's body, using it to heal, to walk, to use their Vampiric Abilities, and so on. The blood has varying degrees of sustenance depending on whose blood it is, with the most filling blood being young men and women in their 20s, the least being blood from animals.

The way vampires obtain blood is through their fangs and ingesting flesh orally for its blood content. For the former, when a vampire feeds on someone without embracing them or fully draining them of their blood like a Feras Sanguinis would, they are known as a "Vessel", and the feeding itself is incredibly pleasurable, for both vessel and feeder. Vessels that are fed on often enough can become addicted to the feeding. After the vampire pulls away from the vessel, there are two fang-sized holes left where the vampire bit the person's neck, which can be licked by the vampire to partially seal, as they could be open to infection otherwise.

As a result of being embraced, Vampires undergo drastic mental change compared to before the embrace, and are now an apex predator. With this, all vampires have an animistic side to them which is similar to Feras Sanguinis, but caused by a lack of self-control over this animalistic side of their character as opposed to a lack of blood.

When a vampire is gravely injured, they can enter a state of Dormita, a hibernation-like state, that allows the vampire to heal its body over time, with time varying wildly depending on the power of the vampire in question. During Dormita, the vampire conserves his blood while healing over his wounds or goes into Dormita due to a lack of blood in the first place.
