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, The Wharfmaster has heard of Marius LePual, a dubious sort of prick, and he's probably hanging out at a waterfront dive somewhere. The other party members go to the Mother's Lighthouse, where Gladys, the Lightkeeper, is a follower of Melora and admits them because Caduceus is, too.
DM: "Depending. When he disappears to do most of his work beneath in the Sluice-- something. There are two submerged gates in the harbor."
Player: The Sluice Weave, perhaps you are talking about?
DM: "The Sluice Weave, yes." Not that you'd know that, technically.
Player: You said Sluice Weave. Oh, they said it? Eh, shit happens. Forget it.
DM: It's fine, it's all good.
Player: Banished from the game!
DM: I know. You're done! Caleb is murdered. No.
