It's stated in the book that it will be described further in future modules. Well, my players just made their chars. One for example is a Swedish paratrooper and my brother, who is also a player (US Airborne Brigader General, the terms never stopped coming

) served att Karlsborg IRL so I am pretty sure the players will want to go there!
I don't have problems with creating my own stuff but It is such a shame. Can you please stop putting things in the middle of the maps that will be described further some other time!
Or does anyone have a brilliant idea for stopping my players from going there before above mentioned, future modules arrive?
