Every soldier who survived the war fears the biological superweapon nicknamed “necroplasm”. Toward the end of the war, American scientists had developed a virulent biocide capable of liquefying living tissue within a matter of seconds. The addition of chemical cannons on tanks and man-sized chemical throwers left toxic puddles of necroplasm all across the American west.
Although there is no living person who fully understands the chemical makeup of necroplasm, one thing is clear: for reasons unknown, radiation bonds to the biocide causing post-war necroplasm to function as a powerful mutagen. Some have even theorized that necroplasm itself has transformed into a living organism.
It is well known that the majority of humanoid mutants are created from direct exposure to necroplasm. However, scientific expeditions led by the Guilds of Academia suggest that prolonged exposure to necroplasmic particles in the air cause reproductive mutations in plants and animals. Luckily, a sealed chemical suit is all that is necessary to keep the biocide at bay. Unfortunately, few wastelanders have access to such a luxury.
As a result of vocal opposition from General Morris Kass, mutants are typically frowned upon in human settlements. In response, the mutant races of the Mo-Javi have formed their own tribes and civilizations, often in close proximity to pockets of radiation. Maps of the wasteland often include known locations of necroplasmic puddles and radioactive hotspots. These areas are known as the “rad-lands.”
Because humans overwhelmingly avoid the rad-lands, these sections of the desert have seen a sort of Cambrian explosion. Life is abundant in these regions and constantly adapting to new threats. It is rumored that a tribe of nomadic shepherds nurture and feed the creatures of the Mo-Javi, though such claims are often dismissed.
