Antaeus is a system composed of four terrestrial worlds and two gas giants. None of the terrestrial planets are livable, although Trebin is undergoing some terraforming efforts. Should those efforts be successful, a helium-3 refining facility is expected to be built on Edmos. The worlds have potential in untapped resources, although exploitation is discouraged for the time being due to rough terrain and hostile environments.

The system has a few mysteries to ponder on. On Trebin is a buried Reaper artifact that transformed the survey team that discovered it into husks. Massive structures have been detected on the gas giant Ploba, although the exact nature of these objects is yet undetermined.
