"Evidently." replies your host. "Very well, allow me to give you the short version. This city has a warren of tunnels beneath it. There are the ones that everyone knows would be there .. storm drains, subway and maintenance tunnels. Then you have the older ones. Pirates and smugglers dug them, way back when. There are also natural caves and tunnels too, though not as many. The deeper you go, the stranger things you find. Go deep enough, you will not come back."<br/><br/>He took a look around the group, to judge if his warning was being listened to or ignored. "Lastly, there is the matter of my fee. Since I operate a secure way in, and frequently more importantly, out of the tunnels, it pays to keep it that way. That means maintenance costs. $25, each, will allow you in. On your return, a 2% fee on the value of whatever you have returned with, or another $25, whichever is more. I am, of course, open to alternate forms of barter." he adds, smiling.
