HMHVV

HMHVV (or Human-Metahuman Vampiric Virus) is a retrovirus that achieves its full virulence and power only in a magic-rich environment—such as post-Awakening Earth. The virus itself has existed throughout history and even expressed in very rare instances during the relatively magic-poor Fifth World. When a metahuman’s immune system fails to stave off infection, the virus begins to systematically re-shape their auras and genetic code—transforming them into forms reminiscent of the night-stalking monsters of legend.

The presence of HMHVV in a subject’s body can be determined by the Harz-Greenbaum blood series or simply testing for the virus itself.
