Luna was a renowned center of human genetic research during the Dark Age of Technology, becoming home to massive underground genetic laboratories. During the Age of Strife, it was ruled over by brilliant but fanatical gene-cults who only submitted to the Emperor after the First Pacification of Luna, the first battle of the Great Crusade.[3] The pacification of the Gene-Cults of Luna allowed the Emperor to mass-produce the Legiones Astartes.[6]

During the Horus Heresy, its naval bases were destroyed by Horus's rebel Legions as they struck towards Terra.[1]

Ten thousand years later Luna again became a battlefield in the final stage of the Terran Crusade. Due to the reborn Roboute Guilliman's efforts to reach Terra via the Webway, Magnus and his Thousand Sons were able to emerge on the moon. In the subsequent battle the Chaos invaders were defeated thanks to the arrival of Imperial reinforcements from Terra that included the Imperial Fists, Custodes, Battlefleet Solar, and Sisters of Silence.[7]

Notable Locations

  • Somnus Citadel - Headquarters of the Sisters of Silence[2]
  • Port Luna - Naval base for Battlefleet Sol. An enormous shipyard capable of accomodating thousands of starships, at the time of the Horus Heresy it was the largest man-made military structure in history.[2a]
  • The Circuit - A massive artificial valley filled with military compounds, command centers, factories, and other facilities.[2a]
  • The Ring - A belt of defensive platforms that form a continuous ring around the planet. Made from rock excavated from Luna itself, it is bristling with countless Lance, Torpedo, and Macrocannon batteries.[2a]
