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, Fortunately, the party is able to kill them with only a few injuries. The noise, however, attracts a pair of slow-moving rock monsters from opposite sides of the river, but Yasha and Jester are able to paddle past them and the boats escape further down the tunnel.
DM: As you move in that direction past the rock slide, you get a faint source of magic further beyond that rock slide.
Player: Beyond the rock slide?
DM: You get a better look at it. Actually, you don't get a better look because you don't have light.
Player: That's on one side of the passage that we are in?
DM: That's on the north side of it, yes.
Player: If I crane my neck in the other direction, is there anything on that side?
DM: Nope. Nothing of magical essence on that side of the chamber.
