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, The spiraling tower of black iron and copper. He throws a square, metal icon.
DM: All right. You leap over, grasping, lose your hand for a second, and get back up there. The soreness is starting to kick in; you're not used to this much physical activity of this type of strength, and it's kicking your ass.
Player: So fast, but so weak.
DM: So fast, but so weak. It's already hot here, and the beads of sweat are pouring down your face at this point.
Player: I have little indoor fans, like I'm a baseball mascot.
DM: Yeah, basically. Thankfully you have fire resistance so you don't have to worry about the heat getting too much on you. It's more of the physical exertion that's getting you. You do eventually pull over to the next window. As you get to it, you pull up into the lip, and as you reach out to grab, your hand hits something. You look up, and you see that this particular opening has an imperfect, thick glass window or at least a glass surface that is currently blocking the entrance. This is actually a window that is closed.
Player: Is it transparent?
DM: Somewhat transparent, yes.
Player: So it's just cloudy?
DM: It's somewhat opaque, because of the nature of its creation it wasn't perfect glass. It's about that thick, and the entire oval is about six feet high, and about four feet wide.
Player: Can I check for traps?
DM: Sure, go for it. Make an investigation check.
Player: Okay, oh good, 27.
DM: All right. This window is trapped. As you glance around, you can see that it is. It is a window that has a slot on the side. The glass is wider than the window in a slot that's pulled up through chains that you gather would probably lift it from the inside, like a winch that would pull it open or closed. However, on the bottom, you can see along the edge. On the very bottom edge, you can see some sort of slight bit of material that doesn't match both the glass or the blackened iron structure of this building. It's a silver plate that rests where the glass sits down. As soon as it would move, a weight would shift, and something would happen.
Player: Looking at it, do I think I could disarm it from this side? Or is it something from the inside of the room?
DM: It would need to be something from the inside. Even if you were to attempt to do it from the inside, you would have to be at the base of the structure. From this side, it's too big for you to do anything, really.
Player: Okay, and I can't see shit.
DM: Make a perception check.
Player: Natural 20.
DM: Which gives you a total of?
Player: Oh, perception? A total of 32.
DM: All right. As you peer in and close your eye on the inside, you can see another bedroom similar to the one over there that you just passed by. But this one is exorbitant in its decor. You see beautiful deep red tapestries along each wall that are the full length of it. The bed itself is a canopy bed that is 40 feet tall with heavy dark silks and fabrics that dangle from it. This is a gaudy bedroom for some sort of a giant.
Player: Any armor on the walls?
DM: No armor visible from this perspective, no. You do see small pieces of art. There are other metallic trinkets that are built into the wall. But nothing that resembles armor, unfortunately.
