And then suddenly comes the Conjunction of the Spheres and you, people, appear here. Human survivors, come from another world, from your former world, which you managed utterly to destroy with your still-hirsute hands, barely five million years after evolving as a species.

Thus unbridled lust never leaves you, sex totally governs you; it’s a drive more powerful even than the survival instinct.
