Found this thread through google, looking for a nice one shot adventure. Was going through the mr fwim one, and maybe I am missing something, but how did you come to those combo sequence to open the hidden door? I figured it has something to with the roman numerals, but I think I'm just misunderstanding something. Thanks!
Welcome to ENWorld

You know, it has been so long (three years) I've that I've forgotten how I created that puzzle! Let me see what I can recall...
[SBLOCK=puzzle in spoilers]
The Wizard's Study (area 9) has the wizard Bittergill's journal...with the chapters seemingly out of order (and missing a few chapters):
III - Wizardly Woes over Pipeweed
II - A Liquor for any Season
V - Audiences with Famous Mages
IV - Vivisection Brainstorms
IX - Spellcraft with a Little Music
VIII - Dining Alone (and I Like It)
Each of these chapter headings references a room in the dungeon for PCs to explore, and each of those rooms has a Roman numeral within it...
III - Wizardly Woes over Pipeweed = Smoking Room (area 14) = roman numeral XVII or 17
II - A Liquor for any Season = Pantry, Reserve Liquors (area 12) = XVI = 16
V - Audiences with Famous Mages = Audience Chamber (area 10) = XXXIII = 33
IV - Vivisection Brainstorms = Giant Mite Dust Stables (area 4, formerly a vivisection lab) = XXXII = 32
IX - Spellcraft with a Little Music = Organ Room (area 3) = LXV = 65
VIII - Dining Alone (and I Like It) = Banquet Hall (area 1) = LXIV = 64
Now, somehow from this point I arrived at a final answer of:
129, 128, 257, 256, 513, 512.
But that's where my memory fails me. Let's see, there's definitely a clear correlation between the numbers as they're presented (i.e. III minus 1 = II, 17 minus 1 = 16, and likewise 129 minus 1 = 128).
There's clearly another step I'm forgetting to arrive at that 129 as the starting number. Must have to do with the roman numeral chapter #s? Hmm. :/ [/SBLOCK]
