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: As he does so, the guy's like, "Jamedi, the captain will be right here-- What?" Just looks really confused.
Player: Is there a way to slip by?
DM: Your stealth check, yes there is. You dart past.
Player: Slip by the back, yeah.
DM: Right at that moment you look over your shoulder, and you can see the captain is now heading down the hallway in your direction.
Player: Okay, I'll make the effect disappear.
DM: He goes, "What? I don't?"
Player: Oh, but I'll leave the effect of the cards still there. [cheering]
DM: You run to the end of the hallway. You see those stairs ascending down into the cargo hold below, and you hear over your shoulder, "And where is he?" "No, but Captain, he was right-- Look at the cards."
Player: Poof!
DM: You hear the argument, and the guy desperately trying to explain what he just saw, as you disappear down into the cargo hold below.
