Lincoln is an ocean world located in the Ragna system. It is a member of the Colonial Confederacy, and it is home to the behemoth shipyard ring of Red Giant Incorporated. While millions of people live in the floating cities on the surface that hover above the seas on giant gravitonic converters, billions live on the Shipyard Ring, making up 45% of the population of Confederate worlds.

The Shipyard Ring is not only the main supplier of military ships for the confederacy, but also the main manufacturer of all civilian goods and ships made in Confederate space. It houses large defensive garrisons, and large defense platforms and orbital guns are in far orbit and artificial stability positions around various hard-points of the station.
