Colonized in the 16th century, Helios is a highly developed world and the corporate headquarters of Heirotus. Industrial output peaked well before Heirotus came along, though fresh investment and development by the company snapped the planetary economy out of a long period of torpor. Unfortunately, industrial output has been sharply curtailed by a recent period of geologic instability.
Major planet-side industries and resources include electronics, aquaculture, and hydrocarbons. While a good amount of Heirotus hardware is still manufactured on the surface, the company shipyards and BTS production lines are scattered throughout the cluster.
