Faction 1 was the original player faction that has now been technically removed. They used to exist alongside Faction 8 as separated deactivated ships and stations in early versions of the game. Now their station designs are merged with the starting faction, Faction 8. Currently, faction 1 contains no blocks, no ships when referenced in sandbox mode, and blocks.lua contains no references to a faction of index 1.
Its default color scheme is blue and light grey. It is often confused with Faction 8.
