Originating in the asteroid belt of Sol the Belters are a large population of miners and space dwellers who have, for centuries virtually monopoloised asteroid mining throughout human space. It is estimated that there are over a billion belters in the Solar system alone.

Fiercely independent, the Belters often have a flexible attitude to the laws and regulations of 'flatlanders' (i.e. those dwelling primarily on planets).

Belters often also take on work as civilian space crew - they rarely join the military as they find the discipline too restrictive.
