The figure salutes you with his trident
Opposite the figure (where I said there was a door, I am going to be a but more precise for the mapper) is a 10 foot passageway leading east, but it goes maybe 5 feet and ends at a door (in mapping terms, instead of the door being at the edge of a ten foot square, it bisects the 10-foot square)
The passageway leads at least another 30 feet south, with a statue barely visible in a west alcove (you are guessing that there is an alcove every other square - 10', 30', 50', etc). There is also an alcove in the section 30 feet south of the door, which seems to have a statue
