Personally I’d really like to the deep dives on towns with fencing masters, mentioning interesting elements of inter- and intra town rivalries for extra setting material. More Codex Superno type stuff would be amazing, especially if there’s anymore islamic or pagan material to be mined up.
Monsterberg II could work if it’s a bit bigger or the characters are more tied into the action, but it’s nice as an introduction to the setting where GMs and groups can continue on with the threads that are still there to make their own adventure. General historical one-shots in Hungary against the Ottomans, Indiana Jones style archeological adventures in Italy or Hanseatic politicking would also be amazing.
