Outside the door, the passage slopes downwards and you follow it for several minutes.
You notice an unpleasant smell which gets stronger and stronger as you go.
Eventually you come to an opening.
Looking through it, holding your nose,
you can see a large open sewer flowing across the passageway.
A rope hangs down from the ceiling.
Will you wade across the sewer ?,
or try to grab the rope and swing across ?
