Coronavirus: The Aftermath

Humankind is on the brink of annihilation. It wasn't guns or bombs that killed billions, but a synthesized germ that swept the globe. The worldwide coronavirus that brought the planet to a halt in 2020 was just a taste of what was to come. Years later, that same organism was weaponized as an agent of genocide - the first salvo in what would become the Final War. Nearly 98% of the world population perished. Although a small number survived, the byproduct of that lethal pathogen only became evident years later when civilization tried to claw its way back from the brink. Yet nearly every survivor carried detrimental vestiges of that horrible contagion. Women rarely conceived. Those that did seldom made it to term. And when a healthy child was delivered, it was almost always a female. The handful of males born in the decades after the apocalypse were usually sterile themselves, making the extinction of our species seem imminent.
Yet somewhere n the deserts of New Mexico, a small community thrives, having been hidden away from the outside world since the global calamity. Secreted in a government facility deep within a modest mountain range rests Emergency Domicile Installation Nine - EDIN. Designed for more than 3000 inhabitants in the event of a national disaster, only ten percent of that number were able to reach safety in time. Most incredibly, the ancestors of the current residents took refuge in the bunker early enough in the war to have escaped the biological agent that wreaked havoc on the rest of the world. Men and women have existed in equal numbers for three generations. None carry any trace of the lethal and destructive coronavirus. They are the only humans left on the planet that can make that claim.
But, in the wasteland, if a single, breedable male is worth killing for, an entire community of them would invite all-out war. And the secret community of EDIN is about to be discovered by the outside world!
