The only settlement on Theev - 2116 A434500-F NA DI is Blacksand City, the world’s capital and downport. Blacksand is built in a maze of canyons, from which skyscrapers of the Blacksand City - Upper City extend high into the dark sky. The upper levels are quite different in character from the Blacksand City - Lower City, and are linked by sealed walkways. It is possible to land small craft atop some of the skyscrapers, and all have grav vehicle ports. Thus there is really no need for most visitors to enter the Lower City, and many would not want to.
