The CSRD was created after the silent conflict between Corneria and a wealthy colony world of Colisus. The Colisusins were a very scientific community and used biological weapons. The Cornerians, after winning the war saw they would need a way to combat unknown threats. So the CSRD was created. But it soon went from a future weapon developing section to a top secret research division.
