The ringed gas giant whose gravity captured the extrasolar object Phoebe, preventing the protomolecule from reaching Earth billions of years before humanity evolved. Phoebe Station, built on Saturn's irregular moon, became the site of the protomolecule's discovery by Protogen researchers. After the Eros incident, Mars destroyed Phoebe Station and drove the moon into Saturn's atmosphere to prevent further protomolecule contamination. Titan, Saturn's largest moon, hosts a significant human settlement and serves as a waypoint for outer system traffic.
