It's a fantasy role-playing game.

DM: You are Caleb Widogast, a human wizard . You are the member of the famous group of adventurers. Previously, you changes Frumpkin into a spider. At the guard shift change after midnight, the group splits into two: Nott, Caduceus, and Keg in one group; you, Beau, and Nila in the other.
DM: Okay. There does not appear to be any person in the courtyard. Those two guards are the only two that were currently set on the outside. You can see the horses that were pulling the carts that are set over on the side at the moment. You can see the carts that have since been repaired and are currently waiting in rest. You can see the front door to the stronghold, and you can see the back door.
Player: Frumpkin saw all of this, yeah? Saw the doors, all of that? I'm going to creep my way to the front door and as I go, I'm going to cast Detect Magic.
DM: You're still on the outside of the wall.
Player: Yeah.
DM: You have to make your way through the perimeter of the wall, which has its own front gate, which is closed. Do you want to head to that?
Player: Right, to the outer wall.
DM: The outer wall and out that way, okay. Cast Detect Magic?
