The Mutacrat are a Xeno race. When the Mutacrat were younger they were a feral people that had stone age technology at best. When an Adeptus Mechanicus vessel crashed on their planet, Mutaset, the Techpriests moulded these Xenos into a technologically advanced race. Now a space-faring race, they are technologically adept, devoted to the Machine God and hungry for new technology.
