“ The name Atlantis came from an old book Victoria had never read. A lifetime residency in the ASM paradise was rumored to cost anywhere from 15 to 20 million dollars. The rich and powerful lived under the dome because they considered themselves separate and superior. Few of them left the comfort and security of Atlantis. To them the outside world was weak. Second Sector citizens where miscreant dregs of a defunct society. In order to enter the Atlantian dome one first had to be cleared by a resident. Gate security personnel strictly enforced this rule, even when outsiders carried a badge and gun. ”
