The Arch is Central

The ship’s engines occasionally release Unobtanium particles into the air, and the Arch maintains an energy field that gathers these loose particles.  Unobtanium particles, commonly called Dust, are the main currency aboard the FHS Justice, and throughout much of the galaxy.  The Arch functions as both a fuel recycling center and as the equivalent of the ship’s mint, purifying the particles for use as money.

Dust is a stable, low energy form of Unobtanium useful for most applications outside of powering the ship. The engines of the ship run on a purer form of Unobtanium that is both higher-energy and less stable, composed of a particular mixture of isotopes. This isotope mixture has been developed to not only power the FHS Justice but also to produce radiation from the engines that supports and enhances human life.

The Arch is huge, and only partially visible above ground.  The rest of its machinery is underground, connecting to the tunnels, corridors, and work areas that underlay each level of the ship. In those areas, the crew work alongside their robots, manufacturing needed supplies, and maintaining the utilities used by the rest of the ship.

Because of the essential nature of the Arch, and also because of the value of the Dust it refines, it is a frequent target of raids by hostile alien species. Dust is used throughout the galaxy as well as by the Heroes on the heroship Justice to enhance powers and weapons in various ways. “Dust raids” are often quick, sharp affairs, with heavy shock troops or elite marauders making a rapid strike against the heroes who defend the Justice in an attempt to steal such a valuable resource.  Counter-raids by heroes attacking alien ships are also possible, although in general these are challenging events, and must be led by the most skilled and powerful heroes.
