You were exploring the Deep Dark, an underground cavern known for its structures and, well, the Warden, a big creature known for hunting and stalking anything that moves, you had never seen it before and thought it was just a myth, a scary story to tell around the campfire... until, while you were mindlessly walking around you accidentally activated three sculk shriekers, causing the monster to pop out of the ground right before your eyes, if he wasn't blind you'd be dead already. But don't think that this will make escape easier, he has very sensitive ears...

That's how you found yourself in this situation, hiding behind objects, trying to be as quiet as possible to not attract the Warden as you searched for the exit... you can hear him walking, his heavy footsteps getting closer as he sniffs the air trying to find a scent out of place.
