This area is a bit of dust and gas that connects the Gran-Dal and Vespucian Arms of the galaxy. Some planetary systems, and some rift areas have little gas for star formation.
There will be usable, and false, lines of travel. A few small ‘empires’ out here. Of course, if Joso or Jalan ever take note of them, and decide to move in, these small areas of control may not last long.
Some of the ‘paths’ through this area could be used as choke points for anyone passing through that some large force might want to block.
There are rumors that the insectoids of Os-Chon backs one or more of these small ‘empires’, but these areas are mostly human.
