Vegas had looser geographical and social boundaries compared to other nations on the Columbia continent.
Strictly speaking, Vegas had only one official administrative area, the capital Vegas. The rest of the territory was land where desert tribes loyal to the Vegas Chieftain resided.
However, there was no commonality among them to label them all with the single term "desert tribes."
Among the tribes were nomads who had lived in the desert for hundreds of years with populations numbering tens of thousands, as well as villages with populations of tens of people formed by salt mining prospectors just a few years ago.
So, the desert tribes varied greatly in size, history, and characteristics.
There was no law that governed them all.
Yet, there was a feature that unified Vegas as a single nation, and that was their affiliation with the security service of the Black Legion, a private army of the Vegas Chieftain.
