Galactic Atlas

Atheri Prime is home to densely clustered predominantly young and middle-aged yellow and orange stars, with stable planetary systems and a generally calm stellar environment. It is home to many temperate terrestrial planets, water worlds, ancient biospheres and complex ecosystems, and has a higher-than-usual tendency towards stable climates. As such, a larger than average portion of the oldest continuously inhabited societies and agricultural centers are found in Atheri. Beneath its forests, deserts, and seas lie the remains of countless forgotten civilizations, and comparatively fewer truly untouched worlds remain.

The Middle Ring contains the greatest concentration of stable, long-lived star systems in the galaxy. Protected from the volatility of the Inner Ring, while also remaining more hospitable to life than the sparse Outer Ring, it is home to the greatest diversity of inhabited planets. The comparatively quiet stellar environment makes eclipses, seasonal cycles, and stable climates common across many worlds. Stars here tend toward remarkable stability, allowing planetary systems to evolve uninterrupted over billions of years. Due to this, countless intelligent species first took to the stars in the Middle Ring, and many of history's greatest civilizations trace their origins to its worlds.
