It's a fantasy role-playing game.

DM: You are Beauregard Lionett called Beau, a human monk . You are the member of the famous group of adventurers. Previously, Caduceus, Caleb, Jamedi, and Nott ran towards the stairs to the outside. you and Jester waited by the well for Fjord.
DM: Top of the initiative order. Beau, you're up first. While you're in water, movement is considered difficult terrain. If I recall, attacks are made at disadvantage while in water.
Player: Okay. Yeah, we're definitely underwater. Do we see the entrance or exit ahead of us?
DM: Those are the stairs that lead upward, yes.
Player: So, if we just book it, we'll go--
DM: Yeah, that's an option.
Player: We're just going to have these guys--
DM: That is entirely an option you can do.
