By the year 3010 humanoids live underground like termites...!
Those in the Western Alliance bunker have vastly increased their
lifespan but reduced their population to 50 because they regard humans
as intrinsically destructive. "We can't be cured, only culled."
The
privileged 300+ years-old elders in this gerontocracy have been
preserved at the physical age of eighty. They are maintained by robots
and a eugenically streamed, short-lifespan humanoid underclass. To
curb veniality further, they are obliged to live by three stringent
edicts distilled from the behaviour of social insects—Conformity,
Rigour and Utility.
Mark5 is a sub-class Sex Cadet streamed to service women elders and he'll do anything to survive as he navigates his way through the carnage and collapsing infrastructure of earth's final brutal civilization.
