An intricate cave system that skips the underground facility completely. It is a natural system that came from earth when Touchdown was first launched into space. Over 360 miles of caverns with tunnels up to 10 miles long and 4 meters in diameter and chambers that reach 40 miles across and 20 miles deep. Each foot of cavern is of raw limestone laced with amethyst, quartz, and topaz that were enhanced to remove the impurities of each crystal. The caves are a popular attraction for tourists and natives both, with tours that last up to 4 hours and cover at most 5 of the 30 chambers and historic spots at each point. The caves are expensive, but the people in charge will barter labor for a chance to explore these amazing natural formations. Aside from guided tours, spelunking expeditions with at least one expert are available for the most adventurous of customers.
