The command ship and namesake for one of the twelve Wayfarer's Collective fleets sent to find new worlds capable of sustaining Terran life. The Cetus was traveling on a parallel course to The Aquarius (presumably heading for Cydonia or Argos) and was commanded by Captain Kojiro Vance. The Cetus fleet willingly changed course prior to arrival to explore a space anomaly known as The Great Divide and was never heard from again.
