No one sees anything immediately strange or dangerous in the tunnel. The tunnel itself appears to quite old though, the brickwork encrusted with decades, or perhaps centuries, or wear and neglect. Best guess is this would be part of the sewerage system from the early 1900s. Obviously it is no longer in use, otherwise things would be much less pleasent.<br/><br/>((If anyone has ideas on searching, feel free to post them, otherwise it will be just ordinary tracking rolls to turn anything up as you move along. When posting rolls, just the final result will be fine. I trust you all :) )
