Suddenly, for no reason I can fathom, I found the interior of the compartment. The creators of this game are way smarter at constructing puzzles than I am at solving them, which is not particularly difficult as I am easily stumped; however, I suspect that very few players will find all of Goetia obvious. Even when I understand the clues I seem to either over-complicate the solution or fall for misdirection, just what I like.
