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, Grog and Arkhan, who are too big to squeeze past the trap, instead lock arms and use the Boots of Spider Climbing to walk across the ceiling. They all reach the other side and carry on.
DM: You guys continue up the next set of spiral stairs, climbing higher and higher up Entropis. You can see, every now and then, one of the various vein-like cracks of energy that's holding the tower together. You can glance out and see, very obscured, movement in the distance. It's too fractured; too much diffraction. Continuing upward, you come to a second, or another, floor. About four minutes of climbing. This next half-chamber, you see dozens of sets of chains and manacles affixed to the walls, where tortured corpses are currently dangling from them, left in pieces. The scent is terrible. Decay is strong.
Player: I cast Divine Sense. Undead.
DM: No undead.
Player: Traps?
DM: Go ahead and make an investigation check.
Player: 18.
DM: Okay. No traps in this chamber.
