Sole source of a nanomaterial that is required to manufacture neuroelectronic interfaces and implant cybernetics
Material forms in the atmosphere of a gas giant, where it is harvested by gigantic aerostat mining platforms
Mines are controlled by factions that are constantly warring and fighting for control of individual mines
The miners and other inhabitants of the platforms have little concern for who is in control of their particular station; they just keep their heads down when the shooting starts and go back to work when it's over.
