The passage runs along for several metres and then ends at a door.
You listen at the door and can hear a
deep heavy breathing coming from inside,
as if some large creature were asleep in there.
Cautiously you try the handle and the door opens.
Just inside, although the room is dark,
you can see that a very large Goblin-like creature is asleep on the floor.
You may either risk tiptoeing into the room,
or you may return to the fork and try the right-hand passage.
