"Perhaps," the Medicine Seller said. He tended to make his rounds through the city - he only really came to Hightown when he needed the money.

"I am not difficult to find, however. I sell my wares at Lowtown and the Gallows as well."

And Darktown. And the Blooming Rose. And the Hanged Man. But he wouldn't invite any to visit the first, it would be rude to imply that this man might frequent the second, and the third... well. Maybe he had a taste for bad beer and Mysterious Meat Pie, who was the Medicine Seller to judge?
