I haven’t actually used this map in a game, but I had some thoughts on what kind of adventure it might be used for, so I made an annotated version and some notes for DMs. The annotated version also gives my ideas on what the rooms might be, in order to make it a little easier to put to use. Of course, feel free to ignore any or all of it and use this map as you please. Let me know what you think (if anyone is reading this).
