Grelia is probably better known for its successful Land registry site.
Due to their strict business nature and meticulous attention to detail they have become a roll model for other planets who wish to set up their own licensed settlements.
The Grelian's have advanced to a stage where they now have little need for external off world trade.
A large percentage of the Grelian population are lawyers, or have employment in the law enforcement sector. Whilst the rest seem happy enough to work menial government approved jobs to keep things ticking over smoothly.
