Core authority

Core authority was a Forerunner organization tasked with tracking slipstream space journeys across the galaxy. It was noted that they could track slipspace journeys if they were rational, while irrational series of jumps were harder to track. The Didact used this to an advantage while on the run from the Forerunner authorities shortly after he was revived from his exile in a Cryptum.
