Shape changers that are able to change into wolves. Also known as the Lupine Virus In the early stages they only change on the full moon and have little control. Once they gain control of their lupine nature they can change at will and are simply more stronger on the full moon and other unique moon cycles. They most often work in packs and sometimes organize into larger groups called Septs. They hunt humans and other animals. They have a taste for hearts. It keeps the Lupine nature in check. People infected with the Lupine Virus tend to have increased hair generation and a increased taste for red meat, usually more rare. Finally werewolves and vampires are at war and battle each other whenever possible.
