Axiom Consolidation
The Culture: Pure Technocracy. To an Axiom citizen, "waste" is the only true sin. Their worlds are Factories. They don't terraform, they process and utilise every isotope of the planet.
The Governance: The Grand Synchrony, an hierarchical structure of elected 7-9 millions brightest minds (augmented by quantum processors) who manage the logistics of thousands of worlds.
The Population: 75% Human. Allow humanoids to join, as long as they follow rules. About 1200 colonised star systems in 4 galaxies.
The Grand Project: "The Threshold", sometimes referred internally as gateway to Zytheralis. It is ultimate purpose of every citizen.
The Goal in this Sector. Research unique worlds to improve utilisation of resources.
