The wartime alliance known as the Purist Coalition formed from the Intellion Union and Bio Confederation during the last of the Genotropic Wars. The primary goal of the Purist Coalition was the eradication of all impure humans in the solar system. Though radical and nearly unfounded, the extremists had won their regime through harsh propaganda. This led to the Purist Crusade that ended with the destruction of Coalition and their subsequent assimilation into the Earth Alliance.
