Lymetis is a desertified rock planet with a thin atmosphere of carbon dioxide and monoxide. The surface has water ice as well as occasional liquid water near volcanic areas. The planet has an abundant supply of zeolites, which the asari use for water purification, as an ingredient in detergent, and as a shielding material for disposal of radioactive waste. A small colony still maintains the mining equipment. Despite centuries of colonization, the asari have developed Lymetis at a modest pace. The planet shows no sign of resource exhaustion.
