Human: Produce a detailed written description of a foreboding scene inside a ship with a door and metal plates. Assistant: 
Heavy, overlapping metal plates have been bolted together to form a narrow corridor, the metalwork so carefully crafted that the entire structure could probably withstand great fluctuations in temperature and pressure. The floor arcs upward from east to west, so that the west side of the room is at a higher level than the top of an isinglass door in the eastern wall.
