11... as in The ELEVEN. So East, 11, should do the trick.
Maybe I missed something, but where do you actually get the information to set the compass to the East? I just saw that Zalvarez0627 mentions in the Wiki walkthrough (thanks for writing this up, btw) that this is revealed by reading the book, but I couldn't find any hint there.
Of course, once you know the holy number you can just do it via trial and error (haha), but so far David always left some hints to make his puzzles solvable without reverting to this method. So I suspect that there is some definite clue that Andoria is to the East. Have I overlooked it? Can anybody enlighten me?
