In the story mission “Utopia”, you explore deep into Titan’s past. As the mission progresses, things appear weirder and weirder. Eventually you arrive at a giant aquarium looking area, and later in a gigantic dome with a hole in the roof. My questions are: what exactly was Titan supposed to be? What did they do? What was that huge dome, and why is there a hole in the top? And finally, why was it abandoned?
