You continue to wade down the sewage pipe circuit. The light shining through some grids above lights your path. Fortunate I guess, 'cause you aint got a torch. You're starting to feel hungry. In the corner of your eye you spot a dark shadow moving around near the wall. You try to get closer to it, but it keeps shooting away. It scamperes off further down the sewer. Well there's nothing much else you can do but to try and find out what it is.
