One day, the USS Jennifer got a call in about a spot underwater where unidentified activity had been detected. So the submarine went to check out what was going on there and were baffled by what they came across. They discovered a small intact part of the city of Atlantis, run by Poseideurk. As gentle as the leader was, he invited them into the city and took them on a trip in Aetheron.
If you’re quick enough to put on your diving suit, maybe you could also make it in time. Hurry up, there’s still a spot left in the train next to Poseideurk!
