"Sir, I believe we are getting closer to discovering the secret meeting place of the underground organization. We have retrieved some documents from one of their agents who was captured last week."
"So, tell me the details!"
"We don't have any details yet, as the documents were written in a language we don't understand. They contain strange words like 'játszótér' and 'kelkáposztafőzelék'..."
"Well, we're not getting too far with those then."
"There is something else, Sir! The package also contained a recording of some kind of transmission. We are not sure how to use it yet, but the experts are working on it already."
"Excellent! Let me know immediately if there is any progress!"
"Will do, Sir!"
Update 2023-10-16: We have received some intel about the meeting spot being relocated due to increased activity of sk8ers in the vicinity, so the coordinates in the transmission need to be corrected by -0.006' N -0.012' E.
