7) The party discovers a grated-over 3 foot wide circular drainage pipe on the south wall of the sewer tunnel. By the looks of it the looks of it the grating looks like it has been opened recently (grate has a hinge and has been left slightly ajar).

If the party continues east, go to 6.

If the party enters the drainage pipe, they must crawl. The party crawls approximately ten hexes south and then the tunnel turns to the east. The party then travels approximately 100 hexes and then the tunnel turns north ten hexes and exits through a grated opening into a larger tunnel that travels east-west (like the tunnel at 3). Go to 8.
