Koszra (CA663781) is a desolate world a little larger than Earth and orbiting an Fclass star. While life is abundant in the oceans and there is oxygen in the atmosphere, the land is a wasteland of sand, boulders and dried mud. It came as a great surprise when first survey of the planet found several dozen oases of complex life, inhabited by a complex ecology made up of dozens of species, with none more than a couple of square kilometers in area. Even more surprising was that the oases were inhabited by an intelligent species that toiled endlessly to maintain the oases, which would have been unstable and prone to dying out without their efforts.
