Core Worlds

The Core Worlds (also known as the Galactic Core and, during the Imperial Period, the Imperial Core) were some of the most prestigious, well-developed, well-known, and heavily populated planets in the galaxy. In astrophysical terms, the Core denoted the central area of the galaxy, and in broad terms this was true enough, but the precise usage of the term was sometimes more complex. The major Rimward hyperlanes radiated outwards around little more than half the galactic disk, and the Core Worlds occupied a C-shaped region of space around the Deep Core, the heart of the astrophysical core (generally considered to be a separate outlier area), extending outwards towards the Unknown Regions.
