Wine cellar
The Yabba obviously didn't believe Link. This was quite awkward.
Thinking a bit, Link said, "Look at me. I can't be a demon right?"
The little Yabba held a short-handle musket. It was like a handgun from earth. At the moment, the muzzle was shaking but still pointed at Link. "Demons are the best at disguises. Those demons outside aren't scary. It's the evil demons pretending to be humans that are. Like Akensser, he's a respected artisan, but he betrayed us all!"
Thus Link learned that there was a traitor from Lirico. It was the artisan Akensser, just like in the game.
Link looked helpless. "There's no point for me to hurt you, right?"
"Yes you do!" the little thing yelled. "Kill me, hurry! I won't say anything."
This intrigued Link. The Yabba definitely knew something.
