CLASSIFIED: Recently, Intel managed to intercept and partially decrypt a series of Ravager burst transmissions. The following brief has been pieced together from these fragments and accuracy is questionable.
The Ravagers are an insectoid race, originating in the distant [No Translation Available] system, far beyond currently detectable exosystems. Long capable of interstellar travel, they left their home planet, [No Translation Available] after resource depletion, atmospheric degradation, and increased solar activity began to render it uninhabitable and the majority of their kind were wiped out. This period is described as “the Great Culling”— a period when all weakness and mercy were purged from the Ravager race. (Apparently, the more militant factions in Ravager society helped in this “Culling”.) The survivors boarded enormous ships and left their dying planet. Probes were sent out in vast numbers to locate and analyze habitable planets. Extremely advanced genetic seeding techniques allowed the probes to deploy virally distributed Ravager genetic material to planet surfaces, where native lifeforms would begin a rapid process of mutation
