Watch out, in this module, as you're approaching the endgame. The second to last section has a typo, on the cut-away map that's meant to be your key to the whole shee-bang. There's also a rather important piece of information/description, missing from a room that's of major importance to that section.
I wish to the Dark Lady that they'd errata these bloody adventures. I really like it, but how do you miss things that are THAT important?
Which bit?
