Fi Solar System
The planets of the Fi Solar System are detailed in the Voodoo Planet novel.
The colony was founded by escaped prisoners—and just one racial stock. They took off from Earth close to the end of the Second Atomic War. It was a race war. One side in that line-up tried to take over Africa; herded most of the natives into a giant concentration camp and practiced genocide on a grand scale. Then they were cracked themselves, hard and heavy. During the confusion some survivors in the camp staged a revolt, helped by the enemy. They captured an experimental station hidden in the center of the camp and made a break into space in two ships which had been built there. That voyage was a nightmare, but they were desperate. Somehow they set down on Khatka without power enough to take off again—and by then most of them were dead.
The humans are a tough breed. The refugees discovered that climatically their new world was not too different from Africa, a lucky chance which might happen only once in a thousand times. So they thrived, the handful who survived. But the white technicians they had kidnaped to run the ships didn't. For they set up a color bar in reverse. The lighter your skin, the lower you were in the social scale. By that kind of selective breeding the present Khatkans are very dark indeed.
They reverted to the primitive for survival. Then, about two hundred years ago, long before the first Survey Scout discovered them, something happened. Either the parent race mutated, or, as sometimes occurs, a line of people of superior gifts emerged—not in a few isolated births, but with surprising regularity in five family clans. There was a short period of power struggle until they realized the foolishness of civil war and formed an oligarchy, heading a loose tribal organization. With the Five Families to push and lead, a new civilization developed, and when Survey came to call they were no longer savages. Combine bought the trade rights about seventy-five years ago. Then the Company and the Five Families got together and marketed a luxury item to the galaxy. You know how every super-jet big shot on twenty-five planets wants to say he's hunted on Khatka. And if he can point out a graz head on his wall, or wear a tail bracelet, he's able to strut with the best. To holiday on Khatka is both fabulous and fashionable—and very, very profitable for the natives and for Combine who sells transportation to the travelers.
This water-logged world combined all the most unattractive features of a steam bath and one could only dream of coolness, greenness—more land than a stingy string of islands. A human could swim—if he wanted to lose most of his skin. There were minute organisms in that liquid that smacked their lips—if they had lips—every time they thought of a Terran.
