The largest of the three decks with high ceilings and wide, expansive rooms with a distinctly earthy scent to the main chamber. Oddly enough the running of water can be heard just on the other side of the great dividing wall as well as what you know in your heart of hearts to be animals despite the absolute impossibility of it all. Over head lights imitate the cycle of day and night though the rhythm is unnatural. The nights are far too long and the daylight seems cast from two originating points. The originating room in the under deck serves as a mess hall and galley of sorts though the cooking devices are strange and confounding. With no fresh food to be found there is always a chance that the many cupboards might hold something of interest.
