Bubbles streamed behind the submarine as it floated along the sea floor.
"Here it comes everyone," said Dr. Smythe, "New Atlantis!"
As the sub burst over the shelf ledge a glorous blue structure rose over the horizon like a galaxy of lights being born in front of them.
"It's beautiful," said Kelly under her breath.
"Amazing," said Sam, "You built this?"
"Seatech, along with 3 countries and a couple billion dollars, yes."
"How did you overcome the pressure? What about prolonged exposure to..." began Benjamin.
"Can it guys," said Kelly, "I swear you'd talk during the Sermon on the Mount.".
New Atlantis stretched its tube-like fingers across the viewing window as it grew even larger, bubbles occasionally billowing up the glass from the sub's motion.
"Hang on," said Dr. Smythe quietly, "this should be fun."
The sub rocked gently at first but it quickly grew to a violent shudder as it drastically picked up speed, rushing forward and away from the ledge.
"Don't worry everyone, we just hit a feeder current slip-streaming over the ledge."
"A feeder for what?" asked Benjamin.
The sub suddenly plummeted straight down into the trench beyond the ledge. The pilot brought the nose down to match their trajectory, stopping the lurching; the city scape disappered as the pitch black maw of the trench devoured their view.
