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: Looking along the walls, you start heading in that direction, you do see a few markings that basically say 'sanctuary' in Thieves' Cant, in the direction of the light.
Player: All right. Confirmed.
DM: You guys continue onward?
Player: Yeah, I'll lead the way. Yeah, we sat here for 20 minutes in the stank.
DM: Yes. (clears throat) So, you guys continue forward up that tunnel. Eventually, as it curves around, the light-- you can see-- it's shifting, because it appears to be a distant fire light that is the source in this vicinity, and as you turn the corner, as the tunnel slowly curves around, it opens up into a large central sewer chamber, though most of it is dry, and you can see there is a large mound of dirt in the center that seems to rise above most of the water that has collected along the ceiling, and there are a series of platforms constructed out of wooden scaffolding at different levels all throughout this chamber. Some of it looks a little rickety, some of it looks very old, but various states of moisture rot. (offscreen sneeze) You hear a sneeze from the distance from one of the-- As you look and see a series of small bonfires throughout the room that are currently lit and surrounded by figures. You see a ramshackle tent city, and/or a series of small, wooden hovels that have constructed here. You see a number of figures that are huddled around these bonfires: cloaks, hoods up, generally keeping warm in what is a relatively cold, subterranean area. You guys, glancing over here, as you're first looking, and you can see a few of them appear to be laid up and hurt, and there appear to be at least a few individuals that are heavily bandaged or have slings on. As you guys step into the room, not being very stealthy in your arrival--
Player: We could have been, but I use a bit of sign language from the Cant, and let them know that I'm part of the Clasp?
DM: Okay. A few of them stand up, hands on the side of their hilt, and stop there for a second before one individual steps out of the shadows and puts his hand up, putting it down. You recognize this to be Garthok.
