\u000a      The colonists' advanced technology eventually leads them to discover the true nature of their universe, a simulation in a super-advanced alien computer. They achieve fleeting contact with the aliens, who for millions of years have existed only as beings of pure computer data. Most of the aliens' culture is incomprehensible to humans, but what little they understand enriches their culture considerably.
\u000a      <<set $system_cultural_database += random(20,30)>>
\u000a  <<else>>
\u000a      The colonists never become aware that their universe is a simulation in a super-advanced alien computer.
