Vampirism is the result of the mutation of a human subject infected by Human Meta-Human Vampiric Virus (HMHVV). HMHVV is, at base, a Chimera Bacteria Integrated Phage of weaponized Tuberculosis integrated with Rabies. The intended effect of the disease was to cause its victims to waste away as the virus consumed their cells to fuel a hyper-aggressive rage that would cause the infected to attack others, and in the process, spread the disease. The Soviet Biopreparat program consisted of 18 research laboratories and centers throughout European Russia. Experiments codenamed Project: Vozrozhdeniye at one such lab working with the Tuberculosis integrated Rabies and several serums intended to produce super-soldiers resulted in the fission of HMHVV sometime in the late 80’s.
