"Big Boss this way."

The kobold leads you through a network of tunnels. As you take note, you notice that they don't try to mislead you, but the path is complex enough you aren't 100% sure you could retrace it. Not to mention any of the traps that are hidden along the path which you might trigger.

In due time, you find yourself in front of Big Boss, who is still the fattest kobold you have ever seen. However, at the moment, he's doing something you'd not think possible: he was standing up and screaming at his attendants in a shrill voice. The squeaking rant seems a parody of the draconic tongue.

He does not immediately notice your entrance and your escort is far more intimidated by BB than he is by you. "Say hi yourself. I'm gone."

With that, the kobold is gone down a hidden side-passage before you realize it.
