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, Even further down, the twins notice a crack in the wall stopped up with a boulder. Grog moves the rock, and they find a side passageway beyond.
DM: 19, okay. As you look across the body, I mean there's nothing formal about this area, there's no fine, chiseled structure. It looks like a natural formation. It just appears to have been the final destination for whoever these individuals were. And you do notice, the way they're adorned, they were an adventuring party. They were people who came down here long ago for whatever reason and the last destination was this small cavernous space.
Player: You said they're covered in webs?
DM: There are webs on them, but the webs themselves are small, natural spider.
Player: Small, natural. So not Bilbo Baggins.
DM: But you do notice that each one of their skulls has a giant hole bored into the bone itself. Different places in the skull.
Player: I'm just going to start searching all of them.
DM: Anyone else want to do anything?
