Ziost I is a vast planet covered by harsh wastelands and nearly impassible landscapes. Found very close to the Ziost sun, the surface of this planet reaches extremely high temperatures during the daylight hours, forcing all animal life into caves and rocky crevices. Due to the scarcity of water on the surface, very few species live above ground. Underneath the surface, however, lies an intricate ecosystem. Networks of caves have been dug by the burrowing animals that live on the planet, creating many cave openings at the surface. These tunnels allow life to escape the heat during the day, but they serve a practical function as well. Explorers have found that these tunnels many times lead them directly to underground mineral deposits, saving the work of prospecting and digging. However, due to the vast deserts that have to be crossed to extract these minerals, miners often look elsewhere.
