In a distant future, humanity's remnants struggle for survival amidst the desolate landscape of a dying galaxy. The story centers on Killeen and his 'Family' – a band of genetically modified humans adapted to this harsh existence – as they encounter Mantis, a fearsome and unprecedented 'manhunter' machine. Unlike other killing-mechs, Mantis is not merely a destroyer; it is a meticulous collector of human minds, a plunderer of living personalities, and a weaver of complex, murderous illusions. When Mantis assimilates Cap'n Fanny, the Family realizes the true, horrifying nature of their foe. Killeen becomes obsessed with understanding Mantis's motives, particularly why it indulges in such elaborate, psychological warfare when it possesses the power to obliterate them instantly. His quest leads him into the depths of Mantis's 'sensorium,' a chilling museum of living ghosts and defiled spirits, where the true, terrifying purpose behind the machine's actions, and the fate of humanity, awaits discovery. This tale explores themes of identity, survival, and the blurred lines between man and machine.
