The opposite of the Natives might be the Mechs. A faction of machines and robots. They are the heavy lifters on Serra. Be it mining, production, or construction. Their artificial brains have a limited amount of intelligence and no sense of creativity. Their main urge is to do the work they are constructed for and preserve themselves. Governmental meetings with them take very long because they are slow to calculate decisions in the complex social matters discussed there. Some of the Mechs are very old. Even dating back to the age before the Schism. They produce new versions of themselves in factories, to fight the constant corrosion gnawing on their mechanical bodies.
