It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously,  Some of them splintered off to try and acquire the goods that were taken from his store, however they apparently had already been stolen from the location they were being stored in, or been delivered already, they're uncertain as to what became of them. But they get the sense that it was probably best that they chose Gilmore over the gold, at first glance.
DM: Okay. Looking at the barrel, there are no traps currently set, and it's not locked. The only traps were on the outside of the cellar, from what you knew previously, and as that mechanism had already been shown to you by Garthok, so that was easily disabled.
Player: I'm not going to go crazy, I'm just going to go to the bottom of the ladder-- in I go.
DM: Okay. So while you guys are taking a rest--
Player: 30 for stealth.
DM: You drop down the ladder. As you head down what probably comes to about 15, 20 or so feet into pitch black-- it's completely dark down there. Do you have any light source, or do you want to--
Player: I have a Flame Tongue Dagger.
DM: Okay, so you pull the Flame Tongue Dagger. It puts out a very, very low candlelight, opens up the vicinity to you as your feet splash down into very, very shallow, a couple inches, shallow water. Looking around you, you are in a subterranean sewer system. The smell hits you as you hit the bottom of it. This is the entire underbelly of Emon, and there is the slight sound of trickling water that's rushing through this tunnel you're currently standing in. The ladder drops close to about a foot above the floor before it comes to a complete stop. Looking to your right, it descends a little further down on that side, and you can hear-- make a perception check.
Player: 22.
DM: Okay. To the right of you, what should be the eastern tunnel, you can hear the sound of trickling water growing louder; it's almost like this stream meets another. As you listen to the left, and the stench is pretty rough in this part, to the left you can see in the tunnel is a very, very faint dim, yellow light that is shifting ever so slightly in the distance as it curves around out of view. It is level to where you are now, actually, slight incline for a little bit.
