It's a fantasy role-playing game.

DM: You are Nott the Brave, a goblin rogue . You are the member of the famous group of adventurers. Previously, Fjord tells them he sees visions of a giant eye, and hears a voice. The sphere reminds him of that eye, and he wants to know where the temple is.
DM: You create the image of him walking back and forth. The guard notices. (spluttering) Pats another guard that you don't see on the upper side of the door. Guard's like, "Is Cosko back? Go get the captain." The other guy goes and walks away, and the other guy stands there nervously looking back and forth. "Jamedi?"
Player: I'll have Cosko moonwalk across the hall.
DM: "Jamedi? Jamedi!" He goes and starts walking in that direction.
Player: Okay, I'll make my run away, my getaway. (trilling)
DM: Okay, you get by, you get outside of the door. Are you running to the right or the left?
Player: Left.
DM: You run to the left. You go running down the hallway, and you're now not that far behind the other guard, who was rushing off and heading up a small set of stairs that leads up to the captain's quarters. You remember this before. You're actually heading away from the cargo hold this way now. You're heading up.
Player: Oh. I don't want to do that.
DM: Yeah.
Player: I'll turn around and go the other way.
DM: Okay, you go the other direction, and the guy who's now walked up towards Cosko, towards Jamedi, is now rushing up to it and goes and is talking to him like, "Sir, hello?"
Player: I'll have Cosko, is there a stairs or a ladder near here?
DM: Make a perception check.
Player: Okay, oh, that's a four.
DM: You're not sure, you see a couple of chairs, a card table that's currently empty. You can see the hallway continues past where this illusion is happening.
