Night Lamp

Jack Vance has specialized in science fiction decadence since his first stories in 1950. This novel's decadent world is called Fader, whose inhabitants have only leisure to pursue since they have a genetically engineered slave class to do their hard work. Fader is threatened by many dangers, but the pleasure-seeking inhabitants are paralyzed by lack of will. Vance has developed his own vocabulary, sometimes tricky to decipher, to convey an alien speech, but the meaning of his invented words emerges as the story unfolds.
