In 2293, a barbaric tribe called the Brutals live in the Outlands, led by Zardoz, a mysterious figure who claims to be a god. Zardoz arms a group of Exterminators with guns and tells the Brutals that killing is good and procreation is bad. Unbeknownst to the Brutals, Zardoz is actually Arthur Frayn, a member of a competing, more advanced race called the Eternals, who live in a paradise called the Vortex. The Eternals are immortal, but they are not immune to disease or sin, which can be punished by aging.
