Krann orbits an ancient red sun, and is bathed in a crimson light. The entire ecology is based on the presence of the red light; the jungle vegetation that covers most of Krann's land masses is jet black, the better to absorb all available light. The rainy season on Krann lasts for several months. During that time, the jungles are lashed by powerful typhoons. The Kluuzot of Krann are lemur-like creatures, with softly glowing, amber eyes and body coloring which, though drab in the red sunshine, seems almost fluorescent under white light. They can see very well in the dim light, but light set at typical human levels of intensity all but blinds them.
For centuries, the Kluuzot lived under a complex feudal system, and their urban centers were linked by an intricate system of flagstone roads. Portions of the jungles were parceled out to barons by kings, and great wars raged in the trees and on the forest floors for resources and land.
The wars stopped when the humans came to Krann. The Kluuzot hoped to learn advanced science and culture from the aliens, but the Imperial scouts were not interested in opening dialogues. They were interested in the huge nova crystal deposits in the lowland plains and jungles - a veritable fortune in precious ore.
The Imperials swooped down on Krann and established a series of mines to exploit the natural resource. They enslaved the Kluuzot to serve as manual labor. The stubborn Kluuzot did not surrender willingly, and in the process of resisting enslavement, saw their entire civilization destroyed. |
