Location from Foundation by Isaac Asimov
Pleasure world turned imperial capital — a planet of resorts and entertainments that became the Mule's seat of power, proving that even paradise can be conscripted.
Kalgan was the galaxy's playground during the Empire's height — a world whose entire economy ran on entertaining the wealthy and powerful. When the Mule conquered it, he kept the pleasure infrastructure running because it served his purposes. A smiling population is easier to control than a resentful one, and Kalgan's entertainment industry provided cover for the intelligence apparatus he built. The transition from resort world to military capital happened gradually and then all at once. One season the visitors were tourists; the next they were officers on leave from the Mule's fleets. The casinos still operated but the high-stakes tables were reserved for warlords dividing conquered territories. The concert halls played the same music but the audiences wore uniforms. After the Mule's death, Kalgan tried to maintain his empire under lesser rulers and failed. The planet became a cautionary tale about power built on one person rather than institutions — the exact lesson the Seldon Plan was designed to teach.
Tropical archipelagos and warm seas under a golden sun. The resort complexes are sprawling compounds of white stone and colored glass, designed for indulgence — swimming pools carved into cliffsides, amphitheaters open to the sky, promenades lined with shops selling luxuries from a hundred worlds. Under the Mule's rule the pleasure infrastructure remained but the atmosphere shifted: armed guards at the spaceport, surveillance drones disguised as entertainment, and a permanent tension beneath the holiday veneer.
