It's a fantasy role-playing game.

DM: You are Caduceus Clay, a firbolg cleric . You are the member of the famous group of adventurers. Previously, Silverware, tools, and coins looted from ships were tangled in the seaweed near the bases of the walls all around the chamber. The Mighty Nein realized that the floor they were walking on was almost completely covered in humanoid bones.
DM: Okay. Glancing around, you can see areas where the seaweed is slowly shifting from the movement of Caleb's Expeditious Retreat. What was once still shifts, and you can see elements of the stone wall behind it. Your eyes barely make out a handful of small carvings in the wall. Small runic letters that are not in line, but at angle sporadically carved at places, but where the seaweed moves over and blocks it.
Player: Does my Detect Magic-- which I think is just barely still up? I don't feel like this has been a ten-minute venture since that.
DM: Yeah, I'd say you're pushing the edge on this one.
Player: It's not much longer, I know.
DM: I'd say as you step into this chamber-- are you heading to the center of it?
Player: No, I'm just coming in and looking around.
DM: As you're standing at the mouth of this, just past the edge, you do not detect anything particularly magical. Then as you take your first step into the chamber, you see this. You almost run into it. In the middle of this chamber, there is a small two-foot pedestal and a disc, a stone disc about that wide and about two feet from edge to edge that is resting on it but at an angle. It looks old. It looks weathered and there appears to be a spiral of runes, two sets of them, that curve inward around each other before merging in the center with one singular sigil where they meet.
