The Equalizer Civilization began as a ideological/technocratic fundamentalist unification of the minor colony world of Pnas Greenen. After unifying the local culture, it developed into an infamous highly expansive human empire that attempted to implement true equality among all humans and human derived civilizations by a regimen of nanosurgical mental modifications and massive agent software networks. The economy was an attempted autotopia, and politically the Equalizers were anarcho-communists who implemented ubiquitous surveillance on a local, planetary and even interstellar scale.
Beginning in the 9600's The Equalizer Civilization blossomed in the sparsely inhabited Monoceros Outer Volume region among a number of relatively low tech local systems. It collapsed within a few centuries, but the wars which accompanied the collapse wiped out most humans in that volume.
