Mercury

Harsh desert planet with shield generators, plains, mountains, wastes, coastal peninsulas under blockade, and major cities like Heliopolis.

Mercury, the harsh desert world of the Red Rising Saga, emerges prominently in Dark Age as a frozen hellscape locked in a brutal Rim blockade, its shield generators and vast plains turned into battlegrounds amid the escalating Solar War. Shielded cities like Heliopolis endure relentless Society assaults, highlighting Mercury's strategic chokehold on the inner system. Though its role is confined to this pivotal volume, the planet's unyielding wastes and coastal peninsulas underscore the saga's themes of attrition and defiance, evolving from a peripheral resource hub to a linchpin of Darrow's desperate defense.
