Woah nelly here we go. Here is a full size map on 8.5×11 quad-rule paper. I’ll be damned if I draw in a grid on this one. And yes, I do have a hard-on for starting my dungeons with 50′ x 50′ rooms. Thanks Mentzer.
The one thing I didn’t pen in are the 40′ stairways in both the upper left and the middle of the left third of the map. You can still see some of the pencil lines. My idea was for one to go up and the other down, but I just couldn’t make up my mind. Oh well.
