Zanethu

Believed to be a post-garden world, Zanethu has large deposits of calcium carbonate in its sedimentary rocks, indicating it may have once had plate tectonics and even plant life. Its swirling clouds of dust and snow may have occurred more recently and blocked the sun, creating a mass-extinction event. Its surface gravity is comfortable and its temperature tolerable by most sapient species.
