When I have good visual images to work with, I can more easily write the details of an adventure. This publication has good artistry and the images are very useful for me as a writer. I am sure that they are also what a DM needs to use in a game situation. You can use the images (or parts of images) by the copy and paste method and place them wherever needed in your own adventure. I like the way the rooms fit together. I like the way they look in a doc, odt or pdf format. The details are taken care of and the options are many!
