So I know the locust origin of being mutations of immolation treatment to simplify the idea… but that was roughly 100 years or so… how did the locust populate so quickly to the point that they were a overwhelming number compared to humans that survived E-Day? Also….. the rest of the world… did locust stop those humans too or is the entirety of the world just the few bits of land that we have seen in media?
