So in my universe the galaxy is divided up into cubical volumes of space of 50, 500, 5000, and 50000 light years (roughly it's actually divided into my own unit types, but they're roughly equal). There are 1000 of the previous areas in the next area up.
Currently I'm calling them Sectors, Blocks, Grids, and Octants, but that doesn't really work, nor does "Quadrant" for the last one, especially since a sector really applies to any area of space in reality so the 50000ly area can be called a sector as much as the 50ly area.
So what are some other names for areas like this?
I'm talking about titles like sector, zone, territory, region, etc. None of those fit and I'm sure I am missing more and limiting my scope of thinking largely due to star trek.
