It's a fantasy role-playing game.

DM: You are Grog Strongjaw, a goliath barbarian . You are the member of the famous group of adventurers. Previously, Vax sneaks ahead to get a closer look around the room. As nothing happens, Percy then leads the way forward onto the platform.
DM: The anvil is right in front of you. He's on the other side of the anvil. You only see the upper part of the torso because he's standing off the platform below it. So you see him from the waist up; he's about 20 feet tall from top to bottom, you only see ten feet of his torso there. The blade's out in front.
Player: And the hammer is somewhere between me and him?
DM: Yeah. Make a perception check to see if you remember which chain it was.
Player: Seven.
DM: There's four chains on each side that are dangling off the side, and you are not sure which one it is.
Player: Oh, it went hanging off.
DM: It went held off the side, so now there are four chains that are taut on each side of the anvil that are vanishing.
