An eastern province of Germany.
Based on empirical research it is assumed that every second Pole is a roguelike developer. There seems to be a critical lack of anything better to do in Poland. They celebrate something called "Fat Thursday". They were Communist, but now they aren't.
Poland is worldwide recognized as the home of the Polar bears, hence their name. They are fierce bears that organize raids over the poles from time to time.
There are trees. Poles are made from trees. Poland is full of Poles. That's how we know there are trees in Poland.
There are prostitutes. We know this because prostitutes are also called "whores". Ore comes from mines. At mines, metal is extracted. Modern poles are made of metal. Many Poles in Poland are modern. That's how we know there are prostitutes in Poland, because where else would the metal come from to make the modern Poles?
Note that this also explains the existence of children in Poland (there are miners, who work at mines) as well as electric guitars (there is metal, which uses electric guitars to make otherworldly sounds).
Poland has a strong history of producing logicians. It was also the home of King Casimir the Great. To understand how eccentric the Poles are, consider that they called him "the Great" just because he did an excellent job running the country and not because he slaughtered lots of foreigners, and just because he saved all Europe from being overrun by the Turks, the usual qualification for greatness.
