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, Caduceus and Shakäste investigate the back chambers, whch are holding chained, gagged humanoid figures. Lorenzo appears and casts Cone of Cold, knocking out Beau and Shakäste, and wounding Keg and Caduceus.
DM: You don't see anybody in there. You could make a perception check if you want to use that as your action. It's up to you.
Player: No, I will stay tucked in my little closet. Is there a way I can hide but still see around the corner? No?
DM: Maybe? Roll a high stealth check, maybe. We'll see.
Player: Nope. I mean 15, it's decent.
DM: Good to know.
Player: I'll just hold my action until I see something.
DM: Okay, good to know. What are you holding?
Player: A crossbow bolt, ready to fire.
DM: You got it. Beau.
