A few years earlier there had been an invasion. Hordes of tall, grey aliens with tusks arrived in spaceships as big as cities. Before all the news went dark, humans named the creatures orcs. The human armies had fought and failed. War crimes were committed on both sides. Eventually, society collapsed and the government was overthrown when food supplies failed. The humans turned on each other. Nowhere was safe. The orcs had rounded up the survivors and locked them away in refugee camps. In the fullness of time, some women had little grey babies.
