Planet Calia

Calia is prone to constant, heavy sandstorms. Trading is performed off-world and farming is impossible. Mining is at an all-time low statistically.

Story
An advantage Calians have is that sandstorms provide protection against hostile forces. Any attacker dumb enough to enter the mainland will have to endure a mouthful of sand before they can even flaunt a weapon. That isn't to say there isn't anybody dumb enough to try.
