I've read and received several comments from a few folks who are having problems viewing the neon blue maps. I'm very sensitive to the issue, as myself and members of my family have had problems with our eyes. In response (because I want as many people as possible to be able to enjoy these maps), I've created a black and white version of the poster map above. Please pass this on to folks you run into on various message boards etc. where The Castle of the Mad Archmage is being discussed.
Edit: Image removed because it is out of date. See new Level 2 poster maps below.
