I've updated the map with what I believe to be the correct orientation of the Nave and following areas. This leads to a much more sensible overall layout. I'm sure the scale is somewhat off, but this leads to the rather neat finale of having the Orb Chamber directly beneath or very near the back hall. I've added some labels to make the map easier to understand as well - though I believe "Main Hall" should say "Entry Hall." It does leave open the question of what shortcut Alexander and Daniel take to avoid the sewers, but one can suppose an unpictured hallway that leads from the Cistern entrance to the caved-in hallway of the nave.
Kein, I hadn't known about the super_secret.rar file, thanks for the hint! Although the maps in that document only cover the first chapter, they show a process that supports the theory of the devs thinking through each area individually rather than designing the whole castle at once.
Here's one little gem I found in that document:
Quote:This map also has some short enAlexanderers with the servants and all shall be easy to avoid.
It looks like they did a find and replace of "Count" for "Alexander" in this document at one point. Perhaps he was the Count of Brennenburg before he became the baron?
