The Diamond States

The Diamond States is the name of a coalition of four salarian city-states on the planet Mak'esh.

History
After the final assault on the reapers the salarian fleet was diminished, amongst the fleet there was only four female salarians. There was a great deal of panic amongst the salarians and the krogan ultimately were forced to protect the females.

The salarians settled on Mak'esh, four bases were established for the protection of each female and her eggs. The bases eventually grew into cities, named for the female they were built for.

Culture
Females typically outnumber males in these cities, most males are not allowed to breed in the city they are born, to prevent inbreeding. Certain males because of their genetics are considered ineligible for breeding, these males typically travel to other worlds.
