Sylvester Archipelago

The large tavern turned out to be truly large. The five-story building housed several rooms on the ground floor where one could eat and drink, on the second and third floors one could rent a bed for the night, and on the fourth and fifth floors there was a brothel.
Upon entering, Gordian found a typical scene for these places.
- New girl, come here!
One of the pimps grabbed a slave girl, tore her clothes, and was about to take her right on the table, to the cheers of his fellow pimps. But the owner of the establishment arrived in time, he pulled the brazen fellow away and gave him a good punch in the eye. The very young girl immediately hid behind her owner. She was very scared, as this was the first time, but clearly not the last, that she had found herself in such a situation.
- Are you completely out of your mind?! Have you forgotten the rules?! You can touch, but you can't have sex! There are slaves in the brothel for that! Go change, - he said to the girl, rubbing his fist.

I was thinking more about invisibility. The problem is that the city is probably teeming with members of the Dragon Clan and their spies. And they will definitely suspect something if a salesgirl leaves the store with some stranger. Although a phantom wouldn't hurt, of course.
