Mars (Sol IV) is the fourth planet in the Sol system.
Most of the settlements on Mars are located under large domes linked by transport tubes. The tubes are heavily reinforced (reportedly indestructible), capable of easily withstanding blasts from grenades and explosives. While humans are capable of enduring the temperature and pressure on the surface, they require a breathing apparatus since the atmosphere does not have sufficient nitrogen-oxygen levels.
