While the mining of the remains of former habitable planets could provide some resources necessary to the development of technology and machinery in the system, some elements were simply not present but were required for the advancement of civilisation.

To this end, gravitational engineers developed new, stronger vessels capable of guiding gas giants and ice giants into long, slow orbits at the outer most edges of the Mavros System. There, if they did not already have a natural moon, space stations were built and placed in orbit around them.

From either their moon or space station, the resources of the giants were then slowly harvested and transported to the inner planets for processing.

There are currently three such giants being harvested.

• Titan-Alpha is a gas giant, rich in hydrogen and helium as well as heavy metal deposits towards its core.
• Titan-Beta is an ice giant, rich in oxygen, hydrogen, nitrogen and methane.
• Titan-Gamma is a gas giant, rich in heavy radioactive elements.
