Second Question

Exploration Stage: Post Office
From: Mr. Black
Description: The airship mission was triggered by a special signal that reached us through the fog. But where did it come from? Miss Woodville claims a slot machine is involved. But in the Upper City, all of them have been out of order for a while. Can you prove you have a working slot machine?
Completed: This token seems familiar... You get these by wining games in the slot machines near City Hall. I haven't been there in such a long time. There's a date of issue on the back of the token; it coincides with the date we received the signal.
