As the party made their way into the tunnel, they were surrounded by the inky blackness that only exists below the earth's surface. Though absolutely man-made, the tunnel had a naturally musty atmosphere, and the lack of airflow made it feel much smaller than it actually was. The end of the tunnel opened up in the massive underground sewer system below the development district. This particular section of the system hadn't had people in it for years, at the very least, and the silence felt tangible.

There were myths about the city's sewers, stories of failed genetic experiments being tossed into them to rot, or to hunt if they managed to stay alive. There were also stories of some gutter folk trying to start a new district in the sewer, but nobody had seen anything to prove that as anything more than rumor. Plus, if there were monsters or people in the sewers, ThyssenKrüpp would have cleared them out long before this...right?
