When an enigmatic and ruthless pathogen known as the "Hollow Plague" begins sweeping through civilization, humanity is brought to the brink of collapse. Unlike any natural disease, this plague doesn't just kill—it leaves its victims hollowed out, transforming them into something unrecognizable and threatening the very fabric of human existence. As society fractures, a desperate race for survival begins. From the ashes of burning towns like Kushville to the shrouded secrets of the first "Nests," a disparate group of survivors must piece together a fragmented puzzle. When a mysterious broadcast—the Signal—points toward a reclusive figure named Lena Vale and a potential sanctuary in Saint Augustine, it sparks a dangerous cross-country journey. But as the missing links of the virus’s origins begin to surface, the survivors realize they aren't just fighting a biological disease. They are facing a calculated, descending dark, and the true horror may not be the plague itself, but the architects behind it.
