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, Vex, Pike, and Scanlan invoke their divine blessings, and Scanlan prepares the Tome of Isolation.
DM: 44? So you stealth up around the edge and you see now, where once it was divided into two chambers, it now seems the chambers converged once more into a single room. It's not very big, and the tower's been slowly tapering the higher up you go. The room is fairly empty. You see a few vases in the corners and some basic ancient decor. Standing, not noticing you're there, you see three figures in full dark armor. Similar to who you fought in the ziggurat, or the one who was guarding the tunnel that led up into Thar Amphala.
Player: They don't look like the big kahuna, they look like the underlings?
DM: The underlings. You see them in the same dark, horned armor. There's one that's humanoid sized and one that looks to be halfling size. Or two of them, halfling size.
Player: From my hidden position, I want to see if I see any traps in the room.
DM: Make an investigation check for the immediate entry.
Player: I'm not entering. I want to do it from my peeky spot.
DM: For the immediate entry for what you can see. You can't investigate from across the room.
