  • French physicist Prosper-René Blondlot discovers N-Rays, an exotic type of radiation, creating the basis for future N-Ray based weaponry.

21st Century Edit

  • The skip drive is invented, allowing spaceships to approach and then "skip past" the speed of light, sparking another space race as corporations began exploring and claiming purchasing rights to known star systems.
  • The Earth Directorate is formed. It begins cataloging stars and selling nominal ownership rights to them.

23rd Century Edit

Early 23rd Century

  • Ten corporations band together to establish the Halcyon Holdings Corporation, pooling their resources to purchase rights to the remote Halcyon system from the Earth Directorate.
  • The first colony ship intended to settle Halcyon, Groundbreaker departs Earth. Upon arrival, the colonists first attempt to terraform the moon Terra 1, but the process causes its ecosystem to mutate and renders the planet extremely dangerous to inhabit. HHC abandons Terra 1 and shifts its attention to Terra 2, where it establishes a successful colony.
  • Using a legal loophole, one corporation obtains exclusive rights to Terra 1. The moon is renamed Monarch, and the corporation re-brands itself as Monarch Stellar Industries. Infuriated by the move, HHC applies a Hazard Clause to Monarch, declaring it an illegal territory and making any corporate activity there a criminal offense.


  • The colony ship Hope, laden with hundreds of thousands of passengers, departs Earth and begins its journey to Halcyon. At some point during transit, its skip drive malfunctions and the ship is forced to continue on using only its slower sublight engines, extending its travel time by decades.
