From MC's Perspective:
Weird Town,
When I reached the City Gate. I was stopped by the Team of City Guards.
"Where are you going?" The Captain asked. He is wearing black clothes. His health complexion is bad. The other guards are not in better condition as well.
The other hand, I stopped my movements and turned towards the Captain.
"My companions are coming. I'm going to invite them. Otherwise, they will enter the wrong route," I replied.
Hearing that the Captain's expression eases a lot.
Then he thought of something before saying,"Wait, for me here."
After saying that he walked away to call someone. The person is none other other than the fat inn owner. The Captain collected the details of all the foreign visitors yesterday.
So he knows that Mask donned person is staying in Fatty's inn. The Fatty then answered the call. After knowing that the Captain is inquiring about the new customer.
