The year is 48,000 AD. Tens of thousands of years have passed since humanity left the solar system. They have spread throughout the galaxy, diversifying into beings significantly different from original humans through genetic engineering and environmental adaptation. Thanks to the FTL technology known as "Gate Jump," thousands of star systems were connected. However, one day, the massive gateway network at the galactic center collapsed, causing civilization to fracture into several factions. This event is known as "The Great Silence." The galaxy is largely divided into five sectors: Core Worlds The galactic center. Home to 40% of the population. The oldest civilization. Concentration of massive gateways. The heart of the Aurelian Empire. Rim Territories The galactic outskirts. Frontier lands. Frequent pirate activity. Operational area for Nomad Fleets. Free Systems Systems belonging to the Alliance. Superior technology. Politically free. Void Zone Regions isolated since the Great Silence. Loss of contact for thousands of years. A dangerous, unknown territory. Abyssal Reach The domain of the Abyssal Lords. Outsiders almost never enter. Human Civilization Level Humanity has effectively reached the "Post-Human" stage.
