Named after Dr. Arthur Keegan, the scientist who first isolated its presence in 2018, the virus was initially believed to be just another strain of rabies. Keegan, a virologist with the World Health Organization, discovered the first signs of the virus in a small village in the Congo, where an unusual outbreak of violent, feverish behavior was traced back to a new pathogen. The virus spread rapidly across the globe, infecting millions within months. Keegan's research was short-lived. By 2019, the infection was already spiraling out of control, and Dr. Keegan himself fell victim to the virus. Infected individuals would display the standard symptoms—delirium, aggression, fever, and necrosis—but those who survived the early stages experienced horrifying mutations that caused their bodies to become unrecognizable, while their minds were often replaced by an insatiable hunger for human flesh. As the virus spread, mutations became more varied and complex. By 2024, the once-predictable zombie-like hordes have evolved into creatures that are far more dangerous, intelligent, and unpredictable. These mutations are far from uniform; each new strain seems to evolve differently, producing monstrous variants with terrifying abilities
