Better Than Any Man Prequel

I am going to run a kind of alternative prequel to Better Than Any Man, set before the death of Gabriele Bauer. The latter entrusts the player characters (all of them are female teenagers) with travelling to the War Room in Cachtice, in Voivodja, in order to figure out the exact position of Gustavus Adolphus' army [I know this is not what is written in the description of the war room, but I'm modifying that— in my version of Voivodja, the war room shows the movements of all armies in all known worlds]. Gabriele Bauer intends to use the information to organise the safe escape of Karlstadt's population before the Swedes are upon the hapless town.
